Background:

Kiran Nimmagadda received his B.Tech degree in Electrical & Electronics Engineering from the Indian Institute of Technology, Madras in 1996. He then went on to graduate studies in Electrical Engineering majoring in VLSI circuit design at the University of Michigan, Ann Arbor, where he was the first student to do research in RFIC (Radio Frequency Integrated Circuit) design. Along with his advisor, he invented a new RFIC subharmonic mixer topology for use in direct downconversion radio receivers and implemented the design using commercial semiconductor processes at Maxim and Conexant. He received the M.S.E.E. and Ph.D. degrees in Electrical Engineering from the University of Michigan in 1998 and 2002. In 2001, he spent nine months as an RFIC design intern at Siliconwave, Inc. where he worked on their cable tuner chipset. From 2002 to 2009 he was an analog ASIC design engineer specializing in telemetry electronics in the R&D department of Advanced Bionics Corp. (later Boston Scientific Neuromodulation) and was part of the team that brought the Precision Spinal Chord Stimulation (SCS) system to market in 2004, which revolutionized SCS therapy for chronic pain patients worldwide. After a decade of industrial research, he transitioned to a career in academic medicine and entered the USC-Caltech MD/PhD program in Fall 2009. After completing the first two years of medical school at the Keck School of Medicine, he joined the USC Neuroscience Graduate Program and the Bioelectronic Research Lab in Fall 2011.
