He is the course director for Human Health and Global Environmental Change and created the HarvardX course “The Health Effects of Climate Change” which explores how climate change influences health through its effects on air quality, nutrition, infectious diseases, and human migration as well as solutions to the climate crisis. Through this course, thousands of students from over 100 countries have learned how climate change directly impacts their lives, and what they can do to become part of the solution.

In 2015, he was awarded a Lokey-Businesswire visiting professorship at Stanford University and has also been a visiting professor at Columbia University. Dr. Bernstein has been a member of the Harvard President’s Climate Change Task Force and co-Chairs the University Food Standards Committee.
