Ana Claudia Arias

Professor
Department of Electrical Engineering and Computer Sciences
University of California, Berkeley

Prof. Arias received her PhD in Physics from the University of Cambridge, UK in 2001. Prior to that, she received her master and bachelor degrees in Physics from the Federal University of Paraná in Curitiba, Brazil in 1997 and 1995 respectively. She joined the University of California, Berkeley in January of 2011. Prof. Arias was the Manager of the Printed Electronic Devices Area and a Member of Research Staff at PARC, a Xerox Company. She went to PARC, in 2003, from Plastic Logic in Cambridge, UK where she led the semiconductor group. Her research focuses on the use of electronic materials processed from solution in flexible electronic systems. She uses printing techniques to fabricate flexible large area electronic devices and sensors.

Sathvik Iyengar

email: sathvik.iyengar@berkeley.edu
Sathvik is a postdoctoral research associate at UC Berkeley, EECS. He is a 2026 Schmidt Science Fellow. Sathvik received his Ph.D. (2025) in Materials Science and NanoEngineering from Rice University, working with Prof. Pulickel Ajayan. His doctoral research led to the discovery of glaphene, a hybrid of graphene and silica glass, and to the first experimental demonstration of quantum flexoelectricity in graphene. His postdoctoral research focuses on interface–driven physics for hybrid logic-memory operation and scaled interconnects, and extending them to flexible/wearable platforms. He is an inaugural Senior Quad Fellow (White House), a JSPS Fellow, and an NSF Research Traineeship Fellow, and was named a Rice Future Faculty Fellow and Purdue Trailblazers in Engineering Fellow (2025). Sathvik is interested in pursuing an academic career. Outside the lab, he enjoys playing the Carnatic Indian violin, advancing his Japanese proficiency, working out, and playing video games.
