Prof Larry Rolen has a new book, titled Harmonic Maass Forms and Mock Modular Forms: Theory and Applications which is available at the AMS bookstore. Prof Rolen is also teaching a special topics course on Modular Forms this Spring 2018.
Larry Rolen is a Visiting Assistant Professor in SoM here at Tech, whose research interests lie in number theory and more specifically modular forms, harmonic Maass forms, and quantum modular forms.
Prof Michael Lacey of the SoM has been called to be a expert witness in a recent case where prosecuters in several capital crime trials have been accused of striking black jurors discrimenently. We had a chance to speak with Michael Lacey about this very important case, and this is what he said.
Potential reasons to strike a juror are manifold, influenced by a number of considerations. Under ideal circumstances, the reasons for striking a juror should be generally race neutral. Namely the reasons for striking a juror should be as prevalent in the pool of qualified white jurors as in the pool of black jurors. Put differently, knowing that a juror is struck should give us very little information about the race of the struck juror.
In a jury trial, there is a pool of jurors which are selected randomly from the county in which the trial is to take place. The lawyers on each side have a certain number of strikes, which they may use to remove potential jurors from the pool. Whomever is left after all the strikes are used are the jurors which will sit on the trial.
In the cases under question, Prof Lacey was called to determine if the likelihood of an all white or nearly all white jury was statistically probable given the potential jury pool in each case.
Prof Lacey uses a deck of cards and elementary counting principles to illustrate the likelihood that all of the potential black jurors in a jury selection pool are struck.
We have a deck of 48 cards, 4 of which are Red Ace cards. Draw ahand of 12, which are the 12 strikes by the prosecution. If the handof 12 contains all 4 Red Aces, then the prosecution has struck all 4qualified black jurors. These are the sorts of probabilities that a pokerplayer would be well acquainted with. They are easy to calculate, andpart of a standard course in statistics.
In the seven cases under question, each jury that went to trial was deemed statistically unlikely to occur for race neutral reasons. Taken together, the likelihood that the jury selection process occurred for race neutral reasons was astronomically small, Prof Lacey says.
The likelihood of the seeing these outcomes in the jury selection is approximately the chance of winning the Powerball Lottery three successive times, purchasing only one ticket with each play.

Prof Prasad Tetali, former interim chair of the SoM, had this to say about Robin:
Robin has a remarkable record as a teacher and a mentor. His tireless efforts to challenge and encourage young talents at critical early stages of their careers has had a profound impact on the lives of a large number of PhD students and postdocs.

TODAY Online news release:
El Pais press release: (in Spanish)
The College of Sciences has selected Matthew Baker as the inaugural Associate Dean for Faculty Development. The position was created to complement the positions of Associate Dean for Academic Programs and Associate Dean for Research. Baker is a professor in the School of Mathematics. He will begin his new role on July 1, 2018.
The Associate Dean for Faculty Development in the College of Sciences is responsible for developing, implementing, and assessing programs that enhance the instructional, research, and career opportunities for faculty. Key areas of responsibility include faculty hiring; mentoring of faculty; faculty retention, promotion, and tenure; and diversity, equity, and inclusion at the faculty level.
“I’m delighted that Matt is willing to be the first holder of this important leadership position,” College of Sciences Dean and Sutherland Chair Paul Goldbart says. “As a mathematician of global renown, an educator celebrated for the clarity of his lectures, and a faculty member with demonstrated accomplishments in service to Georgia Tech and the worldwide mathematics community, Matt is well positioned to advance our deep commitment to the professional development of faculty members as thriving, fulfilled researcher-educators who have extraordinary impact.”
Baker joined Georgia Tech in 2004 as an assistant professor of mathematics and was promoted to full professor in 2011. As a pure mathematician, he is treasured by the international mathematics community for the depth, power, and creativity of his research in some of the most demanding aspects of pure mathematics, such as algebraic and arithmetic geometry. His accomplishments have been recognized by numerous awards, including his election as a Fellow of the American Mathematical Society in 2012 and selection for the Simons Fellowship in Mathematics in 2017.
As an educator, Baker is deeply committed to enhancing students’ experience, even in the most challenging mathematics courses. This has brought him awards for teaching excellence from both Georgia Tech and the University System of Georgia. Baker is also a thoughtful and effective leader, as he demonstrated during his service as Director of Undergraduate Studies in the School of Mathematics.
“I’m honored to have been selected, and I look forward to being part of the College of Sciences leadership team,” Baker says. “I am eager to build upon the faculty-mentoring activities that Associate Dean for Research Julia Kubanek has introduced in recent years. I hope that my unique perspective as a mathematician is helpful in addressing issues of diversity, equity, and inclusion – and of fairness and transparency in hiring, promotion, retention, and salary considerations. I look forward to supporting the needs of our diverse, accomplished, and ambitious faculty.”
