Professional Biography:

I am doing post-doctoral research at NASA Ames since 2016. My current research is focused on understanding the role of radiatively active clouds on the process of dust lifting and maintaining background dust opacity during northern hemisphere summer on present day Mars. I use NASA Ames legacy global circulation model to study radiatively active clouds and its impact on dust lifting schemes like wind stress and dust devil lifting and current Mars climate. I have used global and mesoscale modeling and data analysis to understand cloud microphysics and dynamics. I received my PhD from Colorado State University with Prof. William Cotton as my advisor. My dissertation was on the impact of dust and aerosol pollution acting as cloud nucleating aerosols on orographic precipitation in Colorado river basin. I have also been involved with field projects where I have taken in situ measurements from aircraft with the Desert Research Institute, Cloud Condensation Nuclei (CCN) spectrometers and compared the CCN spectra with cloud droplet spectra to obtain a better fundamental understanding of cloud physics. I have a Master’s in Atmospheric Sciences and my thesis was on ‘CCN relationships with cloud microphysics’. I have another Master’s in Electrical Engineering with my thesis focused on ‘Generation of spectral nulls in Electromagnetic noise produced by DC-DC Converter’; and a Bachelor’s in Electrical Engineering.
