Chair’s corner Graduate enrollment increases by 20 percent The beginning of the academic year is always an interesting and exciting time. This year we welcomed into the department 36 new graduate students, for a total of 138, and over the last two years we added seven new postdoctoral fellows, four new fac- ulty members, and six new lecturers. We are teaching more than 9,000 students this semester, and enrollments in our graduate classes have increased by an astonishing 20 percent during the last two years. Special congratulations are in order to our Phi Beta Kappa undergraduates; to our Women in Science Fellows; to our former PhD student Oscar Perdomo, PhD’00, who received a prestigious research award from the Colombian Academy of Sci- ences; to Professor Roger Temam, who was awarded the Prix Jacques-Louis Lions prize by the French Academy of Sciences; and to Professor Chuck Livingston, who received the Lester R. Ford Award from the Mathematical Association of America. I hope that you will get a chance to look at the articles about these people in the current issue. Other interesting articles describe Professor Matthias Weber’s research in geometry and the undergraduate research project at Cummins Engine Corp. supervised by professors Michael Jolly and Koby Rubinstein. We also extend our best wishes and thanks for their many years of service to our recent retirees, professors William Ziemer, Madan Puri, and Thomas Bagby.

It consisted of solving a certain partial differential equation in order to determine the probability of one gene type taking over a population. This PDE approach is an alternative to direct simulation of a random process. Two numerical techniques were applied to solve the PDE. Students Xiao- hong Che and Saied Yasamin used a finite element package, and George Mohler de- veloped a finite difference code. The proj- ect considered the case of three gene types that lead to a PDE in a triangle (see figure 1). It has laid the groundwork for the study of populations with more gene types. In particular, the finite difference code can be generalized to reasonably solve the case of four types where the PDE would be in a tetrahedron. The faculty mentors for this project were Elizabeth Housworth and Mike Jolly. The engine project was carried out in conjunction with Dan Oren, an engineer, and Mike Sharp, a statistician, both in the Fig. 1: Solution to a PDE connected to the gene project
