DESCRIPTION:Title: On Voting Preferences\n\nAbstract:  The central problem 
 I want to talk about is how to measure voter preferences in a ranked choic
 e election.  Just from voters' rankings\, can we "learn" whether there wer
 e distinct blocs of voters\, who preferred distinct slates of candidates? 
  To study this\, we came up with some interesting ways to measure differen
 ces between rankings and between ranked objects\, and we developed some ex
 act optimization (IP) approaches.  Much of this should be applicable to ot
 her studies of preference.  (There's a much bigger modeling literature on 
 consumer preferences and web rankings than on voting\, for some reason!)  
 This is based on joint work with Kris Tapp and with our own David Shmoys.\
 n\nBio: Moon Duchin’s research focuses on discrete geometry and randomiz
 ed models\, with applications to the study of voting and democracy. She is
  a member of the faculty at the Brooks School and the Department of Mathem
 atics\, affiliated with the Center for Data Science for Enterprise and Soc
 iety. Duchin was hired as part of the Provost Office’s Radical Collabora
 tion initiative. A prominent voice on fair redistricting\, Duchin has deve
 loped mathematical models to analyze the potential and actual outcomes of 
 changes to policy and voting districts. She has served as an expert in red
 istricting litigation in Wisconsin\, North Carolina\, Alabama\, South Caro
 lina\, Pennsylvania\, Texas\, and Georgia. Recently\, her work has turned 
 to the study of alternative systems of election. Her research has been rec
 ognized with a National Science Foundation Faculty Early Career Developmen
 t Award (NSF CAREER)\, a Guggenheim Fellowship\, and a Radcliffe Fellowshi
 p. She was a Sloan Professor at the Simons-Laufer Mathematical Sciences Re
 search Institute (SLMath) for their recent program on Algorithms\, Fairnes
 s\, and Equity.  She is a fellow of the American Mathematical Society. Pro
 fessor Duchin received her Ph.D. in Mathematics from the University of Chi
 cago. Her undergraduate degree in Mathematics and Women’s Studies is fro
 m Harvard University.\n\nPanopto Webcast
