Only three current members of Congress have Ph.D.s in a science, technology, engineering, or math (STEM) field. [View all]

Jerry McNerney Democrat CA-11 Mathematics University of New Mexico
Bill Foster Democrat IL-11
Physics Harvard University
Shri Thanedar Democrat MI-13 Chemistry (Polymers/Organometallics) University of Akron
No current US Senators have one.
We can add another in the US House in 2026:
Megan ORourke (Democrat), running for NJ-7, got her Ph.D. in agricultural ecology from Cornell University, earned tenure at the Virginia Polytechnic Institute and State University (Virginia Tech), and worked as a government scientistuntil President Donald Trumps administration left her work in limbo.

Hopefully there are others running as well.
We need far more STEM Ph.D. scientists and far less bankers/investors, business executives, corporate lawyers, etc in Congress.
