Experience

Post-doctoral Research Scientist (Associate Specialist); August 2014 - Present Earth Research Institute (ERI), University of California Santa Barbara, CA Project and Research: The Madden-Julian Oscillation (MJO) and predictability of extreme precipitation in the United States and other extra-tropical regions.

• Performed time series analysis on large data sets of hind-cast forecast for extracting trends and forecast- skill; resulted in one publication in a leading climate journal and presentations at conferences.

• Designed numerical experiments to analyze the changes in trends and associated mechanisms, work currently in progress.

Post-doctoral Research Scientist; January 2014 - July 2014 Center for Ocean-Land-Atmosphere Studies (COLA) Fairfax, VA Project and Research: Monsoon sub-seasonal variability in the tropical regions in observation and simulations.

• Processed very high resolution and high frequency data (big data sets) to derive products on which time series and composite analysis were performed to extract trends and mechanisms; results published in a leading climate journal and presented at conferences.

• Designed and carried out numerical experiments on General Circulation Models (GCMs) to extract the dynamics and mechanics associated with the trends by adding spatially and temporally varying signals, which improved the GCM’s variability, publication material is in review.

• Calculated the forecast and predictability skills of Indian monsoon in the European Centre for Medium-Range Weather Forecasts (ECMWF) model in gradually increasing spatial resolution data sets (MINERVA Project); results presented at conferences.

Research Assistant; May 2007 - June 2008 Raman Research Institute Bangalore, India Research: Analyzing Properties of Electromagnetically Induced Transparency (EIT).

• Worked on EIT experimental set-up to conduct experiments and analyzed output (time series data sets) to study the absorption properties of different transition levels; results published in two physics journals and presented at conferences.
