I am presently a Stein Fellow/Lecturer in the Department of Statistics at Stanford University. Previously, I was a Postdoctoral researcher working with Prof. Hans-Georg Müller, who is also my PhD advisor, and Prof. Jane-Ling Wang in the Department of Statistics at University of California, Davis. I finished my PhD in June 2019. Prior to this, I received a Bachelor of Statistics in 2012 and a Master of Statistics in 2014 from the Indian Statistical Institute, Kolkata.

My research centers around developing statistical methods for nonEuclidean data, examples being distribution and network valued data and time varying object data. Here is a link to my CV. In June 2021, I will join as an Assistant Professor in the Department of Data Sciences and Operations at USC Marshall Business School.

I love to sketch. In my spare time I sometimes go on sketchcrawls. I also love hiking.

Research Interests

Modeling and inference for dynamic networks- generating mechanisms and reconstruction of network archeology.


Interface of statistics and metric geometry - broadly applicable statistical methods, theory and inference for analyzing metric space valued data with applications in brain imaging studies, child neurological development, traffic network analysis, social network analysis, genetics and compositional data.

Functional and longitudinal data analysis and its overlap with metric geometry- with focus on studying samples of dynamic metric space data, examples being time varying networks, distributions or tree valued data.

Online learning problems- specifically contextual multi-armed bandit problems with unconventional contexts.
