Samanvaya Srivastava

B.S. and M.S., Chemical Engineering, Indian Institute of Technology Kanpur

Ph.D., Chemical Engineering, Cornell University

Postdoc, Pritzker School of Molecular Engineering, University of Chicago

Samanvaya is an Assistant Professor in the Chemical and Biomolecular Engineering at UCLA. He completed his undergraduate and master's work from the Indian Institute of Technology Kanpur and his Ph.D. with Lynden Archer from Cornell University, all in Chemical Engineering. Before coming to UCLA, he was a postdoctoral scholar with Matthew Tirrell at the Pritzker School of Molecular Engineering at the University of Chicago.

Samanvaya's research interests are in understanding the influence of intermolecular interactions on material structure and properties, with a broader aim to combine this fundamental understanding with molecular engineering and self-assembly processes to improve materials design. Samanvaya has received various awards, including the Austin Hooey Graduate Research Excellence Recognition Award at Cornell University (2013), the RSC Researcher Mobility Grant (2017), AIChE 35 under 35 (2020), and the NSF CAREER award (2020).

Visiting Research Scholar

B. Kollbe Ahn

Ph.D., Kansas State University

Postdoc, University of California, Santa Barbara

Before joining UCLA, Kollbe was a faculty member at UCSB and UCF, and has recently left his tenure-track professor position to focus on his roles at several companies located in the greater LA area as CEO, Board of Directors and Advisory Board member. He has managed several millions of dollars of multiple government/industrial R&D funds as PI, and authored numerous high-profile publications (e.g., Nature Materials, JACS, and Science) in the field of surface science and biomaterials. He is currently affiliated with UCLA and UCSB, and maintains his academic activities. His research interest is to translate the chemistry of biological organisms to synthetic materials for biomedical applications.
