We engineer membrane interfaces where molecular separation, chemical reaction and switchable transport happen in the same place.

ABOUT THE LAB
Membranes that do more than sieve
Membranes that do more than sieve
The RAMP Lab designs interfaces where separation and chemical reaction happen together, and where transport can be switched by redox state, applied potential or the surrounding chemistry. The goal is separation processes that use less energy and fewer chemical inputs than running each step on its own.
Chemical separations account for a large share of industrial energy use, and they struggle with complex mixtures, low selectivity and dilute product streams. Coupling reaction and separation on one platform attacks those bottlenecks directly.

Why Reactive and Adaptive Membranes
Why Reactive and Adaptive Membranes
Chemical separations are among the most energy-intensive and challenging operations in industry, often limited by complex mixtures, low selectivity, and dilute product streams. Reactive and adaptive membranes address these bottlenecks by coupling reaction and separation within a single platform, enabling more efficient, sustainable, and versatile chemical processes.
