Nageswari Shanmugalingam , PHD

I received my Bachelors degree from the University of Rochester in 1994 and my doctoral degree from the University of Michigan in 1999, under the supervision of Professor Juha Heinonen. More up-to-date information can be found on my
google website  or the website https://homepages.uc.edu/~shanmun/

Ph.D: University of Michigan at Ann Arbor 1999

BSc: University of Rochester Rochester, NY, 1994 (Physics, minor in Astronomy)

My research area is geometric analysis. I am interested in the connection between inequalities in analysis and their geometric implications, and also in quasiconformal maps and the geometric properties of metric measure spaces conserved by them. I am also currently interested in the geometry behind the theory of functions of bounded variation (BV) and Besov spaces, and I am also interested in various notions of boundary in potential theory, and in the study of transformations of metric measure spaces that preserve bounded geometry.
