Ilissa Ocko

Climate Scientist

Areas of expertise: Climate change, aerosols, black carbon, climate modeling


Ilissa Ocko helps EDF and the Office of Chief Scientist with anything concerning climate change. Ilissa’s main focus is helping EDF prioritize black carbon mitigation efforts based on the best available science.


  • Ph.D. and M.A., Atmospheric and Oceanic Sciences, Princeton University (2013)
  • B.S.E., Earth System Science and Engineering, University of Michigan — Ann Arbor (2008)

Ilissa Ocko used climate models in graduate school to explore how aerosols, such as black carbon, influenced various climate conditions over the past century. She has a certificate in environmental policy from the Woodrow Wilson School, has done scientific illustrations for groups like Climate Central and Weather Underground, and as an undergraduate she was a weather anchor on the university’s television network.
