Assistant Professor, Department of Bioengineering

Dr. Prashanth Asuri joined the Bioengineering faculty at Santa Clara University in Fall 2011. Dr. Asuri earned his Ph.D in Chemical and Biological Engineering from Rensselaer Polytechnic Institute, where his research primarily focused on engineering protein function and stability through control of its nanoscale environment. After graduation, he served as a research scientist at Solidus Biosciences for two years, where he developed high-throughput predictive cell based assays for facilitating the metabolic toxicity analysis of drug candidates. Dr. Asuri also spent two years, from 2009-2011, as a postdoctoral researcher at University of California, Berkeley, where he applied biomolecular and material approaches to obtain a better understanding of mechanisms and conditions underlying the neuronal differentiation of human pluripotent stem cells.

Research

Current Research Interests
Our lab interests are interdisciplinary in nature, integrating tools and concepts from biomaterials engineering, biotechnology, and cell biology. Our current efforts focus on the use of hydrogel biomaterials to develop in vitro platforms that mimic in vivo conditions to explore the role of biophysical cues on controlling protein structure and function and regulating cell fate. We are also interested in the design and development of hydrogel nanocomposites for applications in tissue engineering.
