Welcome to the Xu Group

We work on designing, characterizing and understanding complex systems of synthetic polymers, nanoparticles and biomolecules to develop new functional materials that exhibit novel electronic, photonic, and biological properties.

Our Research

Join Us

We are a diverse, interdisciplinary group at the University of California Berkeley. Our members have backgrounds and research interests ranging across the fields of materials science, chemistry, biology, mechanical engineering and computing.

We are always looking for talented and motivated graduate students and postdoctoral researchers to join the group. Interested applicants, please send a copy of your CV to Prof. Xu. Interested undergraduate students should reach out to a postdoctoral researcher or graduate student you would be interested in working with!
