I began working at Lehman College in Spring 2000. Before taking the job here, I earned a doctorate at the Courant Institute in 1996 and then worked as a postdoc at Johns Hopkins and at Harvard. I am also a doctoral faculty member at the CUNY Graduate Center and a frequent visitor at Stony Brook, where I work with doctoral students and postdocs conducting mathematics research.
My research is in the field of Geometric Analysis: Riemannian Geometry, Metric Spaces, and Geometric Measure Theory. In the Fall of 2013, I was a visiting research professor at MSRI as part of the program on Mathematical General Relativity. In the Fall 2018 and Spring 2019, I was on leave to serve as a member of the Institute for Advanced Study (IAS) and also as a visitor at Simons Center for Geometry and Physics (SCGP). Here is a Report on my 2018-2019 Fellowship Leave (pdf). Here is a 2013 Research Description which was distributed when being nominated for American Mathematical Society Fellow by Shing-Tung Yau and by William Minicozzi.
I was selected as an AMS Fellow in 2015 "for contributions to geometry, including the study of Ricci curvature, and for mentoring activities, especially for young mathematicians from underrepresented groups." In 2024 I was selected as an AWM Fellow for "utilizing every opportunity to open pathways to mathematics for more women and students by creating and maintaining online access to advice, mathematical resources, and information about women mathematicians; for organizing the “Inspiring Talks by Mathematicians” lecture series featuring under-represented speakers, and for dedicated and active contributions to the Association for Women in Mathematics."
