Steven Spallone obtained his PhD in 2004 from the University of Chicago. He was a postdoctoral fellow at Purdue University and the University of Oklahoma before joining IISER Pune in 2012.
Our primary research focus is developing the theory of characteristic classes for representations of familiar groups, such as Lie groups and symmetric groups. This includes invariants such as determinants and spin structures. We are also interested in the arithmetic theory of partitions, and its application to symmetric groups.
