2008 Sacks Prize awarded to Epstein and Raghavan

The 2008 Sacks Prize Awarded jointly to I. Epstein and D. Raghavan

The ASL Committee on Prizes and Awards has selected Inessa Epstein of the 
California Institute of Technology and Dilip Raghavan of the University of 
Toronto as the recipients of the 2008 Sacks Prize. The prize consists of a 
cash award plus five years free membership in the ASL for each awardee.

Epstein received her Ph.D. in 2008 from the University of California, Los 
Angeles, under the supervision of Greg Hjorth. The Prizes and Awards 
Committee citation notes that in her thesis, Some results on orbit 
inequivalent actions of non-amenable groups, she "solves one of the most 
important problems in measurable group theory, the resolution of which 
involves a combination of deep results from different branches of 
mathematics.'' Raghavan received his Ph.D. in 2008 from the University of 
Wisconsin at Madison under the supervision of Ken Kunen. The Committee 
cited that his thesis, Madness and set theory, "uses modern methods 
associated with independence proofs to obtain, just using $ZFC$, results 
on almost disjoint (MAD) families, that in particular solve a twenty-year 
old problem of Van Douwen.''
