Principal Investigator

Dr. Alyosha “Al” Molnar is an associate professor in the School of Electrical and Computer Engineering at Cornell University. He received his BS in engineering from Swarthmore college in 1997. After spending a season as a deck-hand on a commercial Tuna fishing boat, Al worked for Conexant systems for 3 years designing RFICs. He was co-responsible engineer developing their first-generation direct-conversion receiver for the GSM cellular standard. That chip, and subsequent variants, have sold in excess of 100 million parts (and are still selling), as well as yielding several highly recognized papers.

When he entered graduate school in 2001, Al worked on an early, ultra-low-power radio transceiver for wireless sensor networks while taking multiple classes in neurobiology. Upon receiving his master’s degree, he changed groups and worked on dissecting the structure and function of neural circuits in the mammalian retina, using a combination of electrophysiological, anatomical and pharmacological techniques, as well as analysis techniques drawn from his Circuits background. In 2009, he joined Cornell as an assistant professor focusing on RF integrated circuits, computational imaging, and neural interfaces.

Postdoctoral Researcher

Dr. Sunwoo Lee is a postdoctoral researcher in Molnar Group. He received his B.S. in Electrical and Computer Engineering from Cornell University in 2010. Sunwoo obtained his M.S. and Ph.D. degrees in the Department of Electrical Engineering at Columbia University in 2012 and 2016 respectively. During his Ph.D., he had worked on chemical vapor synthesis of high quality graphene, and signal processing and force-sensing based on graphene nano-electro-mechanical systems (GNEMS) resonators. Sunwoo is currently working on microscale opto-electronically transduced electrodes (MOTEs) for tetherless neural recording.
Sunwoo has received Outstanding TA Award from Mechanical Engineering Department at Columbia University in 2011, Qualcomm Innovation Fellowship 2012 and 2013 (first to win two years in a row), and Pi-Star Award for Young Researcher Presentation, CARBONHAGEN in 2015.
