Ojas Pradhan PhD | Data Science for Buildings

About

I am a doctoral researcher in the Building Science and Engineering Group (BSEG) led by Professor Jin Wen at Drexel University.

My research interests include application of machine learning, big data tools and timeseries analysis to develop innovative AI-based solutions to address environmental challenges and promote sustainable practices. My current work focuses on developing data-driven strategies to optimize performance and control of smart Grid-interactive Efficient Buildings (GEBs).
