I'm an Assistant Professor in the Department of Biostatistics
at Johns Hopkins Bloomberg School of Public Health. Prior to
this, I completed my PhD in Biostatistics from
University of Minnesota
under the supervision of
Dr. Sudipto Banerjee and
Dr. Hui Zou.
I'm interested in all aspects of spatial and spatio-temporal statistics . Application areas include air pollution , ecology and forestry data.
I'm also working on spatial disease mapping and plan to explore spatial models for neuroimaging, Earth system models and assessing health effects of environmental
My research interests also include developing the theory and methodology for high-dimensional data , small area estimation , and
Bayesian hierarchical models .
See my research page for more details on my projects.

I'm looking for PhD students to work on ongoing projects on spatial statistics and small area estimation.
Currently there is funding for the following projects:
- Small area estimation of key populations relevant to infectious diseases using survey data
If you're interested to work on any of these projects, please contact me.
If you've a dataset or an idea for a project, and want to discuss with me, feel free to email me or walk into my office anytime I'm there.
