Dr. Daniel M. Westervelt


Climate change and air pollution scientist


I am currently a Lamont Associate Research Professor at Columbia University’s Lamont Doherty Earth Observatory in Palisades, NY. I am also an affiliated scientist with the NASA Goddard Institute of Space Studies in New York, NY, and an air pollution advisor to the US State Department. I am an affiliate faculty of the Columbia University Data Science Institute.

Prior to Lamont, I worked as a Science, Technology, and Environmental Policy (STEP) postdoctoral research associate at Princeton University.

I completed my PhD degree in May 2013 in Civil and Environmental Engineering from Carnegie Mellon University, under the supervision of Dr. Peter Adams.

Outside of work, I enjoy sports, science, reading, and New York City living.

All future news will be posted to the Westervelt Aerosol Group website
