Kate Juschenko Kate Juschenko works in the field of operator algebras and group theory. She obtained Ph.D. in 2011 from Texas A&M University. She did one year postdoc in EPFL, Switzerland and was an assistant professor in Vanderbilt University during Ben Weinkove one year. Originally from Manchester (England), Ben Weinkove obtained his bachelor’s degree from Oxford University. After Aaron Naber receiving his Ph.D. from Columbia University in 2004, he was a Benjamin Peirce Assistant Professor at Harvard University Aaron Naber’s current and a Royal Society Research Assistant at Imperial College research interests focus on London. He received a Sloan Fellowship in 2008. He held the study of geometrically a faculty position at the University of California, San Diego motivated equations and before arriving at Northwestern in the Fall of 2012. In Winter their applications. His 2013, Ben was appointed full professor. His research is in the work primarily focuses on area of geometric analysis and complex geometry. the study of manifolds with Ricci curvature bounds, whether it be lower or upper, and their possible denegenerations in limit spaces. He also works in the other areas of interest, primarily regarding sectional curvature, minimal varifolds, Ricci solitons, harmonic maps between riemannian manifolds, mean curvature flow, Ricci flow, and elliptic equations. Math Faculty Retiring in 2013 Clark Robinson was born in Seattle dynamical systems. These systems are deterministic so there and received his B.S. degree from the is no uncertainty or chance in how they evolve.
