Samanvaya Srivastava received his PhD from Cornell University, where he worked with Professor Lynden A. Archer on the structure and properties of nanoparticle dispersions. In particular, his work was aimed at developing strategies for achieving uniform nanoparticle dispersion in polymeric matrices and the effects of particle distribution on bulk properties in nanocomposites. Prior to this, he received his BTech and MTech degrees in chemical engineering from the Indian Institute of Technology Kanpur. In his MTech research, he worked with Professor Ashutosh Sharma on investigating the role of physical heterogeneities on substrate surfaces as manifested in the electric force induced patterns in thin polymer films. He currently works as an assistant professor at the University of California, Los Angeles.
Samanvaya's research in the Tirrell Group involves investigating the structure and assembly kinetics of polyelectrolyte complex- (PEC) based micelles and hydrogels using various scattering techniques (SLS, SAXS, SANS, DLS, and XPCS), with the aim of preparing an extensive structure map and elucidating morphology transitions of electrostatically assembled hydrogels. At the same time, he is also working on elucidating the materials properties of these materials and working towards establishing a comprehensive structure-property relationship database for the hydrogels.
He is also working on understanding the underlying mechanism of Actin encapsulation in PEC coacervate domains and illustrating the feasibility of reversible Actin assembly in presence of PEC coacervates and its effects on the properties of the coacervate droplets.
