1-27-2009: On January 6, 2009, Aaron Pixton Received the 2009 AMS-MAA-SIAM Morgan Prize for outstanding research in Mathematics by an undergraduate student. The Frank and Brennie Morgan Prize for Outstanding Research in Mathematics by an Undergraduate Student recognizes and encourages outstanding mathematical research by undergraduate students. It was endowed by Mrs. Frank Morgan of Allentown, Pennsylvania. The citation for the award is as follows.

Aaron Pixton is the winner of the 2009 Morgan Prize for Outstanding Research by an Undergraduate Student. The award is based on five impressive papers in addition to his Princeton senior thesis. One of Pixton's papers has already appeared in the Proceedings of the American Mathematical Society, two others have been accepted by Forum Mathematicum and the International Journal of Number Theory, and two others have been submitted. In addition to being creative, Pixton's work spans a remarkable range of topics, including combinatorial number theory, modular forms, algebraic topology, and Gromov-Witten invariants. Pixton participated in Research Experience for Undergraduates (REU) programs at Cornell University, the University of Wisconsin-Madison, and the University of Minnesota Duluth, and wrote interesting papers at all three. One of his mentors described his ``ability to digest current research papers, to formulate interesting questions ..., and within a week's time, to start solving [them]" as ``simply astonishing" and considers his work as ``probably stronger than many Ph.D. dissertations." Another mentor describes the ``depth and breadth" of his papers as ``amazing."

Biographical Note: Aaron Pixton was born in Binghamton, New York, and has lived in nearby Vestal, New York, all his life. He was interested in mathematics from an early age, when he enjoyed reading recreational math books. His formal study of mathematics began when he took various math classes from Binghamton University during high school. Pixton spent the past four years studying mathematics at Princeton University, from which he graduated in June 2008. During this time period, Pixton took advantage of opportunities to work on original research both at Princeton during the school year and at REUs during the summers. Pixton is currently at the University of Cambridge doing Part III of the Mathematical Tripos. Next fall, he will be returning to Princeton to enter the Ph.D. program there, where he plans to study some combination of number theory and algebraic geometry. Pixton's nonmathematical diversions include playing chess, reading fantasy books, and watching his seven cats.

Darryl Daugherty got a teaching position at Lycoming College in Williamsport, PA.

Elizabeth Wilcox got a visiting position at Colgate University after graduating from our department.

Jamil Ferreira, who was in our graduate program for four years, and worked with Alex Feingold, sends some news about his current situation in Brazil. His work is at the Department of Mathematics of the Universidade Federal de Ouro Preto (Federal Univ. of Ouro Preto). There are several nice pictures of Ouro Preto in the internet. This town has been named as a cultural patrimonial of the humanity by UNESCO.

He has written (in Portugese) and published a book on the rigorous construction of various number systems. You could see some more information at Jamil's Book Information and then click on "A Construcão dos Números". The publisher is the Brazilian Math Society (Sociedade Brasileira de Matemática - SBM).

He is studying function fields and some applications to cryptography, but his main activity is still teaching algebra and analysis for math undergraduate students in the math major.

His children: Iara (9) and Maíra (almost 7). They dance ballet, study music and practice swimming, besides regular school and lots of playing.

6-16-2012: Viji Thomas got married on Feb. 4, 2012 in Baroda. It was a traditional Indian Christian wedding with about 850 guests. His wife's name is Brittany Serafini (now Brittany Zachariah, as his church name is Zachariah). They got married at a second ceremony in Dushore, PA, on April 21, 2012. His wife will join him in India in Oct, 2012. Viji has been a post-doc at the Tata Institute of Fundamental Research since September 2010. He will be there until September 2012. After that he will be going to the Kerala School of Mathematics, where his collaborator from Spain will join him for a year, and they will be working together on a problem. Even though The Kerala School is a new research institute, it is historical. It is historical because at this location, mathematicians had done work in Calculus about 2 centuries before it was done in Europe. So a lot of Calculus was done by this school in Kerala. This institute is supposed to be built at the same location where this historic school was located centuries ago. You can read about this historic school here : Keraia School of Astronomy and Mathematics
