Ethan Meitz

Computational scientist

I’m a mechanical engineering PhD researcher at Carnegie Mellon. I use physics, machine learning, and high-performance computing to understand the world—from vibrating atoms to interacting proteins.

I’m exploring AI-for-science research roles, with a focus on scientific discovery through machine learning and high-performance computing.

Outside the lab

Art, drumming & Habitat for Humanity

I grew up in St. Paul, Minnesota. Outside research, I draw, paint, and play drums. I’ve also spent many hours building homes with Habitat for Humanity, including a summer of AmeriCorps service in 2019.
