Data Scientist II, Pacific Northwest National Laboratory, Richland, Washington (May 2022-Present) My role involves designing, developing, and implementing statistical and machine learning techniques to analyze data across multiple application domains of national significance including renewable energy siting, environmental surveillance, military installation resilience, site contamination assessment, wildlife habitat analysis, climate change, decarbonization-related energy system interactions, and environmental and energy equity.
Graduate Research Assistant, Department of Statistics, Kansas State University (January 2019- April 2022) The research project included collaborative work with Dr. Trevor Hefley at Department of Statistics and Dr. Alice Boyle at Department of Biology. The project was based on identifying the key climatic drivers of population fluctuations in highly mobile animals in Konza prairie, Kansas using long-term multiple sources of community data. I've used data fusion to jointly model multiple sources of data in a hierarchical model framework to model the species distribution and species abundance. Moreover, I used theory and tools from missing data literature to account for missing data issues in data.
