    At Putnam, students rise to the challenge

    For the third consecutive year, MIT placed first in the William Lowell Putnam Mathematical Competition and dominated the upper rankings. Among 4,275 participants from 554 colleges and universities in the 2015 contest, 57 of the top 199 scorers — nearly 30 percent — were MIT students.

    The Putnam, a prestigious annual contest for undergraduate students in the U.S. and Canada, is highly challenging even for the math-inclined pupils that choose to participate. The highest score this year was 99 of 120 possible points, and the median score was 1, according to the recently released results. (At least half the students received a score of 1 or 0.)

    “We are tremendously proud of MIT’s undergraduates who have dominated the William Lowell Putnam Mathematical Competition over the past dozen years,” says Michael Sipser, dean of the School of Science. “It is a privilege and a pleasure to have such talented students. Congratulations all!”

    The winning team was made up of MIT juniors Mark Sellke, Bobby Shen, and David Yang. Two MIT students — Yang and freshman Yunkun Zhou — were among the six competitors with the highest individual scores and were named Putnam Fellows for their achievement. Freshman Danielle Wang received the Elizabeth Lowell Putnam Prize, awarded each year to the highest-scoring female student.

    “The depth of MIT’s dominance is unprecedented,” says Tomasz Mrowka, the Singer Professor of Mathematics and head of the Department of Mathematics at MIT. “Each year since 2004, we’ve had at least 20 students receive an honorable mention. And every year since 2002 — with the exception of 2011 — at least two MIT students have been Putnam Fellows. Congratulations to our students, absolutely amazing job.”

    The school with the first-place team receives an award of $25,000. Each first-place team member, as well as the winner of the Elizabeth Lowell Putnam Prize, receives $1,000. Putnam Fellows receive an award of $2,500.

    Zhou, who took the exam for the first time this year, competed in the Harvard-MIT Mathematics tournament and the International Mathematics Olympiad as a high school student. “I think the competition is hard, and I was really fortunate to be among the Putnam Fellows,” he says.  “Some people said this year’s test seemed to be harder than the one last year.”

    Peter Shor, the Morss Professor of Applied Mathematics, was the faculty coordinator for MIT’s 2015 Putnam team and taught course 18.A34 (Problem Solving Seminar) to help freshmen prepare for the exam. Shor was himself a Putnam Fellow as an undergraduate student at Caltech.

    “Most problems, you don’t need to know more than calculus to solve, but you need to be clever,” says Shor. “There are some standard tricks you can learn that are used in Putnam problems regularly, but there are also problems where you haven’t seen anything like it before. Those are probably the best ones, but also the most difficult.”

    The exam consists of 12 problems, worth 10 points each, that students tackle across two three-hour sessions. The first problem of the exam is relatively straightforward; the last problems of each session — A6 and B6 — are the trickiest. This year, not one student received full points on B6.

    “The hardest problems, which are the last problems of each session, seem to require some trick or some very sophisticated way of looking at something,” says Bobby Shen, a junior who was a member of the winning team and one of the top 16 individuals. “Sometimes the solutions are short, but the way to find them is difficult.”

    Doing well on the Putnam is an impressive feat — but the test score is not a measure of all mathematical strengths, Shor emphasizes.

    “They have to know elementary math reasonably well, and they have to be quick and clever in terms of solving math problems — which isn’t necessarily the same types of strengths that make great mathematicians,” says Shor. “Some people that do well on the Putnam go on to do great mathematical work. But other people who are great mathematicians did not do well on the Putnam, and vice versa. It’s a question of speed versus depth.”

    All-MIT Diversity Forum highlights progress, challenges for campus community

    Pieces of tangible progress and reminders of ongoing challenges blended together on Friday at the All-MIT Diversity Forum, a day-long Institute conference where participants addressed the many facets of sustaining an inclusive educational community.

    “This year, in many ways, our students have become our teachers,” said MIT President L. Rafael Reif, in his opening remarks at the event.

    Reif was referring to actions the Institute has taken in recent months, partly prompted by requests made by MIT’s Black Students’ Union (BSU) and its Black Graduate Student Association (BGSA).

    Overall, Reif said, MIT aspires to sustain an ethos of “decency, humility, respect, and kindness” on its campus, especially with regard to matters of ethnicity, religious pluralism, gender, sexual orientation, and physical disability. 

    “I believe that in our best moments, we are that kind of community,” Reif added.

    The forum also provided a public platform for speakers to emphasize the many benefits of diversity in institutions of all kinds.

    “Diverse groups solve major problems,” said Lorraine Goffe-Rush, MIT’s vice president for human resources, asserting that organizations that draw upon a broader variety of perspectives are better able to reach their goals.

    Over 425 members of the MIT community attended the event, which was held in Kresge Auditorium and the Samberg Center.

    “A matter of justice”

    The forum’s morning session featured a forthright panel discussion, with extensive audience participation, covering topics from campus-specific diversity issues to the politics of resentment that have become a part of the current U.S. election campaign.

    Melissa Nobles, dean of the School of Humanities, Arts, and Social Sciences, noted in her remarks that many people have been watching the ongoing election with “amazement” due to the charged statements about ethnicity and religion being deployed in the presidential campaign.

    At the same time, plenty of people find it easy to ignore the possibility that discrimination and prejudice may be widespread in society, observed Abubakar Abid, a graduate student in electrical engineering and computer science at MIT.

    “There are many people who don’t believe it’s a problem,” said Abid. “I know, because I used to be one of them.”

    By his own account, Abid became more sensitized to the presence of prejudicial attitudes by taking MIT’s course 9.75 (Psychology of Gender and Race), which helped him perceive how deeply embedded social attitudes may be.

    “Multicultural education is key to solving problems,” said Abid. “It challenges us.”

    As such, Abid added, he is now more keenly aware of developments that highlight a lack of tolerance in society — such as the recent episode in which a town in Georgia, near the place where he attended high school, blocked the building of a new mosque. 

    Ed Bertschinger, professor of physics and the Institute community equity officer at MIT, added that those who rarely encounter prejudice have a responsibility to be mindful of its existence.  

    “I’m privileged to belong on campus,” Bertschinger observed. Referring to a recent incident in the news, he said: “I’m privileged to board an airplane speaking a language that the other passengers consider natural to them, and not to be removed from the airplane for speaking my native tongue.” Such events, he noted, “are uncomfortable experiences, and our response to them must not be to ignore them.”

    Other panelists attested to the transformative personal effects of becoming involved in efforts to establish social rights and equity.

    “Participation in social movements has a profound impact on us as people,” said Sasha Costanza-Chock, an associate professor in MIT’s Comparative Media Studies/Writing program, who has studied social activism extensively — and holds the view that a career in academia does not prevent scholars from actively supporting civic causes.

    Tanalis Padilla, a panelist and professor of history at MIT, emphasized that inclusiveness is not just a political stance or civic attitude, but a moral imperative that stems from taking equality seriously. We should “act on diversity not as a mere question of respect for difference, but as a matter of justice,” Padilla said.

    With progress, discord

    Today’s activists, of course, are also striving to sustain the advances made by other advocates, politicians, or family members in decades past, many of whom, as some panelists pointed out, fought for change in seemingly more difficult circumstances.

    In the morning panel, Jelani Cobb, the director of Africana Studies, an associate professor of history at the University of Connecticut, and a staff writer at The New Yorker magazine, pointed out that his father had left Georgia for New York City, sight unseen, in hopes of building a better life for himself and his family.

    As a result, said Cobb, at times “it makes me feel ashamed if I feel pessimistic” about the possibility of further racial progress in the U.S., no matter how contentious or regressive political debate may appear at any given moment.

    Cobb also gave a keynote address at the forum, emphasizing that social progress and political discord often accompany each other in American society, during repeated episodes in which “people are concerned that their country has been infiltrated by people who don’t look like them.” At stake, Cobb emphasized is the question, “Who is included in this idea of ‘We the People?’”

    Whatever advances in civil rights have been earned over time, Cobb added, progress is something that has to be guarded and actively preserved.

    “Vigilance matters,” Cobb contended, adding: “James Baldwin said that the world is held together by the love of a shockingly few people.”

    And while politics and policy in the U.S. have often been justified on the basis of American “exceptionalism” in democratic, economic, or military terms, Cobb suggested the concept should be given another meaning: “I would like to live in a country that is exceptional in confronting its shortcomings.”

    Student proposals and new MIT policies

    The forum’s afternoon session included workshops and a town hall meeting, which addressed concrete policy changes, among other subjects.

    MIT Vice President Kirk Kolenbrander has been leading a working group of MIT’s Academic Council, which is implementing a series of BSU and BGSA recommendations to promote diversity and tolerance at the Institute. The student proposals were submitted in December 2015.

    As Kolenbrander noted during the town hall meeting, MIT has already budgeted in a 10.4 percent increase in undergraduate financial aid for the 2016-17 academic year, and is in the process of implementing a series of other major student recommendations.

    These measures include expanded diversity orientation for undergraduate and graduate students. Undergraduates will have diversity orientation sessions in small focus groups, to be held in spaces designed for diversity and inclusion, as well as online diversity training programs. Graduate students will also be required to have diversity training, and there will be university-wide orientations sessions for incoming graduate students of underrepresented ethnic backgrounds.

    MIT Medical has also expanded its counseling capacity to assist students who are dealing with race-based traumatic stress — a BGSA proposal — and, in response to a BSU recommendation, has hired a psychologist who specializes in issues relating to the African diaspora.

    That specialist will be one of two new psychologists starting in the summer of 2016, along with a new internal medicine specialist who has experience directly relevant to the concerns of diverse student populations. In the meantime, psychologist Stephanie Pinder-Amaker, director of the college mental health program at McLean Hospital, has been holding on-campus meetings to address salient issues with members of the community.

    The working group is also implementing student recommendations concerning the collection and release of data about ethnicity and MIT. This project will include data about why students of color turn down offers of undergraduate admission to MIT; the addition of new questions about diversity and inclusion, to be added to the MIT Quality of Life and Undergraduate Enrolled Student Survey; the release of data (with appropriate levels of privacy) about those questions; and annual, updated data about undergraduate academic pathways for underrepresented minority students,  including major retentions rates and enrollment statistics by course.

    Kolenbrander lauded the student groups for their constructive proposals and ongoing engagement with the MIT administration.

    “It’s exactly this kind of example that creates change in our community,” Kolenbrander said.

    In further remarks at the town hall, MIT Chancellor Cynthia Barnhart emphasized that the Institute’s leadership group had “worked closely” with the student groups. And Bertschinger noted that the student-administration dialogue had expanded beyond the two initial groups to include other student organizations.

    “There are many [additional] groups whose recommendations have been received,” Bertschinger said.

    Kolenbrander also announced that Judy “JJ” Jackson will be rejoining MIT as the diversity and inclusion officer, to help accelerate diversity initiatives on campus.

    The administration is continuing to work with MIT departments and programs individually to address recommendations of the student groups, which have called for increases in underrepresented minority faculty and students within the next decade, and have asked departments to craft statements affirming their commitment to diversity.

    The MIT history faculty, for one, has already released its statement on diversity — which the administration has termed a “compelling” example while acknowledging that collaborating with every department on these matters will be an ongoing process.

    “The work continues and needs to advance,” Kolenbrander said.

    National Academy of Sciences elects four MIT professors

    Four MIT faculty members have been elected to the National Academy of Sciences (NAS) in recognition of their “distinguished and continuing achievements in original research.”

    MIT’s four new NAS members are: Arup Chakraborty, the Robert T. Haslam Professor of Chemical Engineering and director of MIT’s Institute for Medical Engineering and Science; Nancy Lynch, the NEC Professor of Software Science and Engineering in the Department of Electrical Engineering and Computer Science; Hidde Ploegh, a professor of biology and member of the Whitehead Institute for Biomedical Research; and David Sabatini, a professor of biology and member of the Whitehead Institute.

    The quartet of MIT professors was among 84 new members and 21 new foreign associates, from 14 countries, elected to the NAS. Membership in the NAS is one of the most significant honors given to academic researchers.

    Arup Chakraborty

    Chakraborty studies the human adaptive immune system, which mounts specific responses to diverse pathogens. The central focus of his lab is to understand the mechanistic underpinnings of this response and to harness this understanding to help design better vaccines and therapies.

    Chakraborty, who earned his bachelor’s degree from the Indian Institute of Technology Kanpur in 1983 and a PhD from the University of Delaware in 1988, is also a member of the National Academy of Engineering. His many awards include a National Institutes of Health Director’s Pioneer Award, the E.O. Lawrence Memorial Award for Life Sciences, the Allan P. Colburn and Professional Progress Awards of the American Institute of Chemical Engineers, a Camille Dreyfus Teacher-Scholar Award, a Miller Research Professorship, and a National Young Investigator Award. He is also a fellow of the American Academy of Arts and Sciences and of the American Association for the Advancement of Science.

    Nancy Lynch

    Nancy Lynch studies the theory of distributed computation. In recent years, her work has focused on questions about ad hoc networks — networks that are constantly adding and dropping members. How can you guarantee that a vital piece of information will reach every member of a network, if the shape of the network is always changing? How can you distribute data across a network so that you won’t lose information if any members drop out, but you won’t overwhelm members’ memory banks with unnecessary redundancy?

    Lynch received her bachelor’s in mathematics from Brooklyn College in 1968 and her PhD in mathematics from MIT in 1972. She taught at Georgia Tech from 1976 to 1981, before joining the faculty at MIT, where she’s been for 35 years. She is a fellow of the Association for Computing Machinery (ACM) and a member of both the American Academy of Arts and Sciences and the National Academy of Engineering. Her many previous honors include Donald E. Knuth Prize for outstanding contributions to the foundations of computer science, jointly awarded by the ACM and IEEE, and two Edsger W. Dijkstra Prizes from the ACM for outstanding papers on the principles of distributed computing.

    Hidde Ploegh

    Ploegh’s Whitehead Institute lab, which he established in 2005, has focused on developing innovative tools and techniques with which to explore the complexities of the immune system and its response to antigens, including those from invading pathogens and cancer cells.

    Prior to joining Whitehead, Ploegh taught at Harvard Medical School, where he led the immunology program. Before moving to Harvard, Ploegh was a professor of biology at MIT’s Center for Cancer Research (now the David H. Koch Institute for Integrative Cancer Research). Ploegh’s honors include a Meritorious Career Award from the American Association of Immunologists and a special National Institutes of Health Director's Pioneer Award in support of “high-risk, high-reward” research. Ploegh earned his bachelor’s degree from the University of Groningen in 1975 and a PhD from the University of Leiden in 1981.

    David Sabatini

    A pioneer in the study of the key cellular regulatory metabolic pathway known as mTOR (for mechanistic target of rapamycin), Sabatini’s lab has been discerning the individual roles that mTOR’s protein components play in diseases such as cancer and diabetes as well as in the aging process.

    Sabatini was appointed a Whitehead Fellow in 1997 after completing the MD/PhD program at Johns Hopkins University School of Medicine. In 2008, he became a professor of biology at MIT and an investigator of the Howard Hughes Medical Institute. Among Sabatini’s many honors are the Paul Marks Prize for Cancer Research and the National Academy of Sciences Award in Molecular Biology. He earned his bachelor’s degree from Brown University in 1990.
