Computing & Engineering

Chemical Engineering major, explained.

Transform matter and energy into useful processes at real-world scale.

Chemical Engineering explores how chemistry, physics, mathematics, biology, transport, thermodynamics, and process design turn materials into safe and useful products. Students commonly study Thermodynamics, Transport processes, Reaction engineering, Process control, and Chemical process design. Programs vary by college, but the field generally combines foundational ideas with applied work so students can investigate meaningful questions, make informed decisions, and communicate what they discover.
