Regi Oommen

Senior Environmental Scientist

As a kid, I loved baseball, especially the statistics and data behind it. I would go through box scores in the paper the next day to keep track of my favorite team and players, logging the information into my Commodore 64. I enjoyed exploring the data and looking for trends. Working at ERG on a variety of emission inventory, ambient monitoring, and air quality modeling projects has allowed me to continue my passion for analyzing big data sets. And now I get to tell the story behind the data too.
