Faculty Profiles

Ray, Pallav

Assistant Professor, Meteorology, Ocean Engineering and Marine Sciences

I work on tropical climate dynamics and its variability using observations, high-resolution models (WRF) and theory.   If you are a prospective graduate student (MS or Ph.D.), please feel free to contact me. For PhD in Meteorology, you will need to apply to the Environmental Science or Oceaography PhD program.  If you are looking for a postdoc, please feel free to contact me as well.
