Research Areas

We develop membranes and catalysts with tailored properties by combining synthetic chemistry, novel processing, and systematic characterization with careful evaluation of performance in challenging applications. Our publications focus on molecular sieve synthesis, crystal structure elucidation, pattern formation, morphology control, and incorporation in engineering devices. Our work is strengthened by substantial industrial interactions.
