Aditya Mishra, Ph.D.

Flatiron Research Fellow, CCM, Flatiron Institute

Aditya Mishra joined the Flatiron Institute in 2017 as a Flatiron research fellow in the Center for Computational Mathematics. He is developing statistical methods and software with applications to microbial data. Before coming to the foundation, Aditya obtained his Ph.D. in Statistics from the Department of Statistics, University of Connecticut, Storrs. His Ph.D. dissertation is on statistical methods for low-rank and sparse recovery in multivariate analysis. He holds a B.S. and M.S. degree in Statistics and Informatics from the Department of Mathematics, Indian Institute of Technology, Kharagpur, India.

Research Interests

My research interest includes dimension reduction, variable selection, multivariate analysis, regularization, statistical computing, compositional data analytics, robust statistics, microbiome data analytics, variational inference,  and marine ecosystems modeling.

I am interested in developing statistical methods and computational tools to solve the challenging data-driven problems in biological science.

As a collaborator in the Simons Collaboration on Computational Biogeochemical Modeling of Marine Ecosystems (CBIOMES),  I use existing statistical tools and develop novel statistical methods to analyze marine data.
