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.
