James Morizio

Adjunct Professor in the Department of Electrical and Computer Engineering

Over the last two decades Dr. Morizio's research has been focused on CMOS mixed-signal microelectronics and ASICs used in translational closed-loop, bioelectronic therapies for wireless neural interfaces. These interfaces include sub-system architectures for neural recording and modulation and analog circuits for low noise preamplifier, high channel count multiplexer and programmable current sources. Dr. Morizio's current research is focused on biomedical instrumentation intended for neurological, digestive and immune system disorders with the research goal for human clinical translation. He has over 35 years of analog circuit design experience in industry and academics and co-inventor of 8 patents.
