      Research on high resolution numerical weather prediction for dense cities. Focused on evaluating and improving boundary-layer parameterizations. Performed data analysis on different observation platforms to gain insight on WRF model performance including satellite systems (Landsat, JPSS, GOES-R), ground-based systems (ceilometer, microwave radiometer, surface weather stations) and aircraft-based measurements (ACARS) of meteorological variables.

      Consulting project for COVID Alliance to build a tool that would assign point-of-interest information to clusters of cell-phone ping data by using OpenStreetMap and Yelp to help quantify the most likely business a person may occupy. Cell-phone ping data was hosted on Snowflake (SQL) databases and Python (Pandas, GeoPandas, Folium) was used to contextualize the ping data with business information (Yelp API) and corresponding building footprints (OpenStreetMap).

      Successfully led a cross-functional collaboration to integrate software within the Weather Research and Forecasting (WRF) model for use in operational weather forecasting using high-performance computing. Conducted exploratory data analysis for model vs observation evaluation of weather model performance. Experience with full-stack web development using Meteor for an online model vs observations system. - Tested the performance of the urban physics module with NOAA's operational framework against observations of winds and temperatures over New York City (high performance computing, urban weather forecasting). -Experience with a physically-based retrieval method for Microwave radiometer measurements -Experience with Meteor framework for building a verification system for boundary-layer observations against WRF simulations.

      I participated on current work to develop a liquid-lens/liquid-piston system with pinned contact lines. I was able to learn the basics of the surface tension phenomena that is behind the design of the system. My tasks dealt with organizing the CAD model of the prototype to be ready for the next stage of development.
