Outside a nondescript office on Madbury Road in Durham sit eight parking spaces, appearing unremarkable to hundreds of passersby each day. In fact, they are part of a trial run, a data collection and analysis experiment, if you will, the eventual success of which could accomplish nothing less than solving the university鈥檚 parking challenges once and for all. For those of you all too familiar with the university鈥檚 perennial parking headaches, you also know that a Nobel Prize (for peace?) would be a fitting award.

The office is the 91制片厂 Connectivity Research Center, and the trial run involves a series of hockey puck-sized sensors placed beneath the asphalt of each parking space. Using wireless communication technology, the sensors record, in real time, not only when a space is open or occupied, but also, in concert with a handy algorithm we鈥檒l call 鈥淭he Parking Space Algorithm,鈥 the likelihood of it being available at any given time, based on general usage patterns.

One need only imagine this capability expanded campus-wide to begin to see its transformational potential. Using their 91制片厂 app, for example, thousands of students, faculty, staff and visitors would be able to enjoy real-time updates about every parking space on campus as classes and work shifts changed over. They also could know when to expect the Campus Connector or Wildcat Transit to be available anywhere on campus to whisk them off to lecture hall or office during peak commuting hours, no matter where they parked.

When this brave new world of transportation arrives, says Robert McGrath, director of the analytics and data science master鈥檚 degree program, 鈥渨e鈥檒l have fewer people sitting in their cars and reading before business hours, idling until a spot opens, or playing the meter game, and more people finding a place to park and getting where they need to go on time, saving on fuel emissions and, who knows, maybe even getting more exercise.鈥

Next stop, Stockholm?

Well, we鈥檙e not there yet . . . but these kinds of small-scale projects with large-scale implications are growing in number as, sensor by sensor, fiber optic cable by fiber optic cable and student by student, a network of scientists and researchers are setting the table for the smart campus and smart world of tomorrow.

How large-scale a future are we talking about?

McGrath offers the wry smile he has smiled many times before when discussing this topic with newbies. 鈥淲hen people think of the next big thing, they鈥檙e usually not thinking nearly big enough,鈥 he says. 鈥The world is going to change so fast and dramatically in the coming years that nobody will quite be ready for it.

An Agile Education
Whether we鈥檙e aware of it or not, we are all familiar with the world being created through the collection, analysis and application of data 鈥 lots of data 鈥 in every corner of our daily lives. Data analytics governs Google鈥檚 and Facebook鈥檚 selection of ads served up to you when you visit their pages and following you when you leave. It allows scientists to model molecular activity in the quest to understand and speed up the application of lifesaving medical procedures (see 鈥淒eep Learning鈥). It allows some airports to simulate and coordinate the movement of huge jets safely to and from their gates (See 鈥淎lgorithm鈥).

It also threatens to undermine our privacy and freedoms and will surely require a massive retooling of the workforce, a concern that McGrath and his small but influential team are working practically around the clock to address. 鈥淲e鈥檙e coping with the speed of change by trying to educate our workforce without knowing what kind of workforce we need,鈥 he says.

Four years ago, there were 14 academic programs in data science in the U.S. Now, there are more than 200. 鈥淚t鈥檚 the fastest growing industry in the world, and some countries (including Australia and Norway) have created entire universities around the subject,鈥 McGrath says. With some of New England鈥檚 heavy-hitting private campuses ramping up, it will be difficult for 91制片厂 to stay on top, says McGrath. 鈥淏ut people may be surprised to know that we鈥檝e kind of owned the Northeast.鈥

Provost Wayne Jones Jr. believes that in an era where big data is everywhere, 鈥渢he analytics program at 91制片厂 has filled a niche for students from all majors interested in gaining these new skills to advance their career.鈥

With well-established programs in computer science, mathematics, engineering, business, health policy and economics, the university didn鈥檛 get serious about analytics until 2012, when Lisa MacFarlane, then provost, appointed McGrath and College of Health and Human Services Dean Michael Ferrara to create a presence at the university for this cutting-edge field. Her charge to the group, recalls McGrath, was to centralize the program rather than 鈥渉aving six different colleges doing six different things鈥 and to focus on an educational mission.

The result was a master鈥檚 degree program in analytics and data science 鈥 colloquially known as DSA, and modestly set up at 10 Pettee Brook Lane in Durham. There used to be a pizza place next door that went bottoms-up. But lunch is not foremost on DSA鈥檚 menu of priorities. What is on the menu at DSA is hard work, which comes in the form of a yearlong boot camp featuring an 鈥渁gile鈥 approach to graduate study that has no exact comparators at 91制片厂 or, seemingly, any other university.

For those unfamiliar with the Silicon Valley mantra of 鈥渁gility,鈥 it refers to the practice of fearless experimentation, finely tuned responsiveness to the needs of stakeholders and adeptness at pivoting on a dime to meet these needs as they change. Agile organizations may write up multi-year strategic plans, but they feel comfortable scrapping them in a heartbeat to address emerging technologies.

If anyone embodies the agile mindset at 91制片厂, it鈥檚 Prashant Mittal, DSA鈥檚 clinical assistant professor. Mittal came to 91制片厂 from the University of Southern Maine Muskie School of Public Service, where he labored in frustration at what he dubs 鈥渢he huge disconnect between what business schools were teaching and what industry needed.鈥

鈥淔aculty become comfortable with a course and stick with it, year after year,鈥 says Mittal. 鈥淚ndustry, on the other hand, is constantly solving new problems requiring new tools and skills.鈥 By Mittal鈥檚 estimation, universities typically lagged about seven years behind industry in terms of student preparation.

McGrath and Mittal were determined to close the gap by seamlessly integrating classroom work with industry relevance 鈥 not through capstone or standalone projects but by baking experiential learning into the fabric of their program.

Over the course of one summer and two semesters, each master鈥檚 degree cohort 鈥 whom McGrath calls 鈥淒atacats鈥 鈥 takes classroom-based modules that run concurrently with two practicums with various industry partners. Explains DSA lecturer Phani Kidambi, 鈥淚f you look at data science programs at many universities, they are basically made up of existing courses packaged as data science. Real data science isn鈥檛 a collection or sequence of courses but a dynamic field that constantly changes.鈥

Far from a 鈥渟equence of courses,鈥 91制片厂鈥檚 DSA classes are densely interwoven tapestries typically involving up to half a dozen faculty members from around the university. A course on data architecture or visualization techniques, for example, may draw on Paul College鈥檚 Billur Akdeniz Talay to teach marketing analytics or Tevfik Aktekin or Burcu Eke to teach optimization. Computer scientist Arvind Naray may come in from the College of Engineering and Physical Sciences (CEPS) to teach a module on programming using the powerful Python tool, and colleague Adam Boucher may be called on to teach mathematical foundations and linear algebra.

鈥淒ata science evolved at the intersection of mathematics, computer science and an area of application, such as health care, transportation, space travel, the environment and so forth,鈥 McGrath says.

The 鈥渁pplication鈥 phase is where the second pillar, the practicums, really shine. Practicums operate like consultancies, in which 91制片厂 student teams, advised by faculty, de- vote large numbers of hours to devising ingenious solutions to problems brought to them by several dozen industry part- ners. Recent partners have included Martin鈥檚 Point Health Care, Lindt Chocolate, Amazon Alexa, the Boston Red Sox, Planet Fitness, Walmart, Unum Insurance, CA Technologies, Granite State College and other local and national firms.

The Stanford of the East?
We鈥檝e already indulged in some good-natured, Nobel Prize hyperbole. Here鈥檚 another one: 91制片厂 analytics is the 鈥淪tanford of the East.鈥

Unlike hackathons and similar events, DSA鈥檚 practicums focus on real problems the partner lacks the time or re- sources to take on. In one practicum, the 91制片厂 team worked with Martin鈥檚 Point Health Care to develop a tool to predict who their next high-cost users would be. Mittal was de- lighted to learn that data scientists at Stanford University ar- rived at a similar approach to their work with insurance giant Kaiser Permanente. 鈥淚 was very proud that although we are far from Silicon Valley and working with a smaller client, we are doing the same kind of thing on a relative scale.鈥

DSA鈥檚 rigorous format not only stands out at 91制片厂, but nationally as well. Just ask Joanna Gyory 鈥19G. Gyory came to DSA with a bachelor鈥檚 degree in biology from Cornell University, a master鈥檚 degree in marine and atmospheric science from SUNY Stony Brook, and a Ph.D. in biological oceanography from the joint program between MIT and the Woods Hole Oceanographic Institution. After a career in academia and a couple years of maternity leave, she wants her next career to be in industry.

鈥淚 enjoyed the theory and research focus of academics,鈥 Gyory says, 鈥渂ut now I鈥檓 really interested in the applied, methods focus of analytics. One great strength of the pro- gram is the diversity of people it draws. They come from sports, music, IT, biology 鈥 you name it 鈥 so I鈥檓 exposed to people with different ways of looking at problems.鈥 Gyory says another difference between her earlier degree work and DSA experience comes from the focus on group projects rather than solitary scholarship. As a result, she says, 鈥淚鈥檝e strengthened 鈥榮oft鈥 skills such as conflict resolution, communication and thinking on your feet.鈥

Soft skills such as communication come in handy during a nerve-wracking rite of passage that has quickly become a hallmark of DSA: Mittal鈥檚 regular 鈥渢eam oral exams.鈥 In addition to written assignments, Mittal regularly devotes class time every week or so to grilling students on current topics, tools and applications. Recent alum Steve Glover 鈥18G recalls these sessions with startling clarity: 鈥淲ith the class seated around the conference room table, Prashant grills us one-by-one. He starts out easy, and then asks harder questions, taking the student ever deeper into a problem until, finally, the student simply can鈥檛 answer a question. Then, he moves on to the next person who may have to pick up where the previous one left off 鈥 if they can!鈥

鈥淭he key to this kind of assessment,鈥 says Mittal with a twinkle in his eye, 鈥渋s not only to know your business but to know how talk about it to other people who may not be experts in the subject. If you can鈥檛 do this, your great ideas aren鈥檛 going to be useful.鈥

Sound cruel? Don鈥檛 worry about these students. The agile mindset is one that embraces failure. 鈥I like to say we are in the business of failure,鈥 explains Mittal, 鈥渁nd that humility is the most important virtue for successful data scientists.鈥 To illustrate what he means, Mittal says he typically teaches his students as many as 75 algorithms to solve a given problem. Students鈥 ability to try one, fail fast and move on to the next option makes or breaks their project.

鈥淭he wisdom lies in figuring out when the pathway you鈥檙e taking isn鈥檛 working,鈥 Mittal says.

And when it comes to self-correction, DSA practices what it preaches, changing roughly 25 percent of its master鈥檚 degree and certificate content each year to reflect the intro- duction of new tools and, indeed, career pathways. From its humble beginnings of 14 students in 2015, DSA has gradu- ated more than 100 students and also offers online certifica- tion for those who don鈥檛 want to devote a year to boot camp. At this point, the program boasts a 100-percent placement rate for graduates, most of whom enjoy higher salaries and more rewarding work.

The success of the graduate program also has led to the development of a bachelor of science joint degree program between 91制片厂 Manchester and CEPS where students can take an analytics track in Manchester or Durham, or a data science track (more foundational math, statistics, computer programming and less applied) through CEPS in Durham.

Innovation and Economic Engine

Datacats

When most people think of campus planning and master plans, they think bricks and mortar, pedestrian walkways and so forth. What they think less about, says Scott Valcourt, director of IT strategic technology at 91制片厂 and adjunct lecturer in computer architecture, 鈥渁re all the things we might learn about what goes on around us and the uses to which we might put this information.鈥

Valcourt鈥檚 talking about a 鈥渟mart campus.鈥 One of the hallmarks of smartness involves the breaking down of data silos, which enables the larger organization to connect the dots and open the lines of communication between, or among, formerly isolated offices. We saw what might happen with 91制片厂 parking and transportation services, but the potential for new and productive configurations is virtually endless.

Consider just a few examples. In the not-too-distant future, campus lighting could be entirely motion-detected, saving enormous sums on energy. Further up the mission-critical food chain, analytics could drive the university鈥檚 innovation and economic engine even more than it does now. McGrath鈥檚 team is already working with a number of university centers, including the new John Olson Center for Advanced Manufacturing 鈥 which engages with New Hampshire鈥檚 manufacturing industry to modernize their technologies and groom the next generation of skilled workers 鈥 and the 91制片厂 Connectivity Research Center (CRC), the site of the parking project noted earlier.

CRC鈥檚 founding director and associate professor of elec- trical engineering Nicholas Kirsch and research program manager Christina Dube are helping the 91制片厂 greenhouses develop a wireless application that can measure pH, mois- ture content and other values without expensive infrastruc- ture. 鈥淚f it works, the application could be used across hun- dreds of university research acres and be commercialized for wider use,鈥 says Kirsch.

McGrath says 91制片厂 is 鈥減oised to become a world leader in environmental analytics鈥 through the collaborative efforts of environmental scientists, data scientists, statisticians and computer scientists who are developing the capacity to build a nationwide network of sensors monitoring streams, waterways and adjoining land areas, with sensors transmit- ting up to 20 data points every 15 minutes.

鈥淭he university has sought national funding to build out the work and develop a doctoral program in watershed infor- matics,鈥 he adds, 鈥渢he first of its kind to bridge what we do in data science with environmental science.鈥

As with the university鈥檚 educational side of analytics, Provost Jones points to the timeliness of the university鈥檚 鈥渢raditional strength in the connectivity of devices and interoperability鈥 as the building blocks for more such industrial partnerships.

An Eye on Ethics
While the upside to such achievements appears endless, some applications of analytics, machine learning, and big data have certainly had a Who鈥檚 Who of critics. Not the least of these involved the late physicist Stephen Hawking, who warned that humans were 鈥渆ntering a new phase of what might be called self-designed evolution, in which we will be able to change and improve our DNA.鈥 Hawking worried that such capabilities would be available mostly or exclusively to the wealthy, creating nothing less than a 鈥渟uper-human鈥 race.

In a similar vein, The New York Times best-selling historian Yuval Harari, author of 鈥21 Lessons for the 21st Century,鈥 argues that science fiction鈥檚 fear of artificial intelligence, captured in films such as 鈥淭he Matrix,鈥 is misguided. What we ought to fear more, writes, Harari, is 鈥渃onflict between a small superhuman elite empowered by algorithms and a vast underclass of disempowered Homo sapiens.鈥

McGrath and his team are well aware of the ethical implications arising from the uses and abuses of machine learning. That鈥檚 why they鈥檝e brought in professor of philosophy Willem deVries to perform the critical role of gadfly, lecturing to every master鈥檚 degree cohort about the existen- tial nexus between human and artificial intelligence, people and robots.

鈥淲e can do all kinds of things we couldn鈥檛 do before, but that doesn鈥檛 mean we should,鈥 deVries cautions students.

DeVries believes that invasion of privacy tops the list of the dangers posed by the 鈥淚nternet of Things.鈥 鈥淎s human beings, we鈥檙e both a physical body and a set of information,鈥 he says. 鈥淎s our information becomes digitized, it becomes available for commercial, political and other uses 鈥 and abuses.鈥 To illustrate, deVries points to the 2016 case of Target. The big box chain captured the public鈥檚 fascination and fear of corporate intrusion on private life when its marketing department used the purchasing history of a teenage girl to figure out she was pregnant before her own family knew. The tip-off came when Target mailers began pitching diapers and baby bottles to her at home. This kind of practice rankles the lifelong Kantian in deVries, who says one formulation of Immanuel Kant鈥檚 categorical imperative places respect for other people at the top of the ethical pyramid. 鈥淜ant believed we should never treat others as a means to our own ends but rather as ends in themselves,鈥 deVries says. 鈥淭his applies to our bodies and our 鈥榠nformation.鈥欌

Count deVries, therefore, among those who remain skeptical about another technology, driverless cars, that touches on a project currently underway between the CTC and the city of Dover. 91制片厂 and Dover are trying to tackle the Garrison City鈥檚 gridlock problem along its main thoroughfares by making the sequencing of stop lights more responsive to traffic volumes.

While Kirsch and his colleagues are in the early stages of installing sensors to measure traffic patterns, the long-term goal is to install wireless communication devices in traffic lights and cars alike. Cars could communicate their presence to the lights and, eventually, to one another, ultimately replacing the human decision-making, with all its flaws, involved in tasks such as braking for lights, avoiding people and other cars, finding alternative routes to destinations and staying in one鈥檚 lane, a feature that is already appearing in new automobile models.

What do you think? Are you ready 鈥 will you be ready in your lifetime 鈥 to cede control of your driving skills to an algorithm?

Or, do you find yourself nodding in agreement with deVries, who argues, 鈥淒riving is very difficult, and it would be, in practical terms, impossible to test thoroughly a system as complex as a driverless traffic control system would have to be. Do we really want to adopt a life-critical system that isn鈥檛 thoroughly tested?鈥

It seems Sheen Estevez wasn鈥檛 entirely right after all: you can argue with the data. What you can鈥檛 do any longer is ignore it. It鈥檚 there by the gigabyte, terabyte, petabyte, and, yes, the yottabyte for us to gather, analyze and apply in an effort to make our world a better place. We can only hope.

No wonder the folks at 10 Pettee Brook Lane are working so hard!

You Know Me Al(gorithm)!

Algorithms are step-by-step procedures for performing calculations according to well-defined rules. Because algorithms describe general truths that work every time, we can use them to perform highly complex, repetitive tasks without having to reinvent the wheel. The Greek philosopher Euclid is cred- ited with inventing the first algorithm in his treatise 鈥淓lements鈥 (300 BCE). The Euclidean Algorithm offers a technique for quickly finding the largest common denominator of two positive integers.

For much of their existence, algorithms were known mostly to mathematicians and computer scientists. Lately, we鈥檙e learning how influential these ingenious tools are in our daily lives.

In the 2015 documentary 鈥淭he Secret Rules of Modern Living: Algorithms,鈥 an Oxford University mathematician considered the ubiquitous smartphone. Every time we take a selfie, an algorithm breaks down the data that comes in through the phone鈥檚 camera aperture and puts a box around our faces to focus on. Hold up a well-composed 鈥渇ruit face鈥 using a banana smile, cherry nose, and oranges for eyes, etc., and the camera still picks out the real face.

Algorithms seem simple 鈥 once experts explain them. Their power emerges when we see them applied to problems of staggering complexity. At London鈥檚 Heathrow Airport, for example, data scientists and aviation engineers devised an algorithm to simulate the entire outward-bound operation of its planes 鈥 from their initial pushback from the gate to taxiing and takeoff. The Heathrow Sequencing Algorithm aims to cut two minutes of taxiing time per plane per year, saving nearly $20 million per year in fuel costs. Now, imagine the reduction in costs and emissions if the world鈥檚 1,200 international airports followed suit. 听

Dedicated to Deep Learning

Clinical trials are expensive and valuable parts of the pharmaceutical drug devel- opment process that companies, investors and, most of all, patients want to succeed. They鈥檙e also long and arduous undertakings often involving patient, disease and treatment profiles that produce enormous amounts of data to sort through 鈥 often compiled in different languages.

It鈥檚 what Chris Bouton, co-founder of Vyasa in Newburyport, Massachusetts, would call a 鈥渃omplex information system.鈥 Vyasa has developed a deep learning platform that helps firms make sense of such systems and, in this case, turn data into successful drug treatments. 鈥淒eep learning refers to creating algorithms that enable machines to learn and adapt more or less like people do, only many orders of magnitude faster,鈥 says Bouton.

In 2017, Bouton hired Justin Greenberg 鈥12, 鈥16G to create an algorithm called Chem Vector, which allows clients to find novel lead molecules to aid in the development of new medicines and treatments. Explains Greenberg, 鈥淩ather than rely on hundreds of scientists to try to randomly mutate a molecule using test tubes and microscopes, Vyasa鈥檚 algorithm simulates testing in a fraction of the time.鈥 Ultimately, a drug will have to be developed and tested on people, but Greenberg鈥檚 algorithm should help Vyasa鈥檚 client get to that critical stage faster.

Like many DSA grads, Greenberg counts himself among his profession鈥檚 鈥渄ata for good鈥 adherents, motivated primarily by a passion 鈥渢o help those in need in order to pioneer humanity towards a better future.鈥 Before coming to Vyasa, Greenberg worked in a hotbed of applied analytics 鈥 healthcare 鈥 helping Elliot Hospital鈥檚 Center for Clinical Excellence successfully design and implement a predictive model for identifying patients most likely to be readmitted within 30 days of discharge.

Greenberg credits DSA with turning his life around. 鈥淚 doubled my income, bought a home and am finding fulfillment in a way I didn鈥檛 think possible,鈥 he says. 听
