Project Ideas for Doctor of Philosophy in Chemical Engineering

Molecular design and process innovation for a decarbonized future.

🏛 Introduction

Northwestern’s ChemE PhD tackles grand challenges—carbon capture, circular plastics, precision medicines—through catalysis, metabolic engineering, and AI-driven process control. Doctoral candidates integrate operando spectroscopy, mesoscale simulation, and techno-economic analysis, often spinning out cleantech ventures with Argonne collaborations and venture-capital mentorship.
