Instructor in Clinical Psychiatry; Adjunct Assistant Professor in Electrical Engineering
Director, Technology Development Laboratory, Division of Brain Stimulation and Therapeutic Modulation, Columbia University and New York State Psychiatric Institute
Dr. Peterchev directs electromagnetic brain stimulation technology development at the Division of Brain Stimulation and Therapeutic Modulation. Electromagnetic brain stimulation has emerged as a valuable research tool as well as a potential alternative or complement to conventional psychiatric and neurological therapies. The objective of Dr. Peterchev's lab is to enhance the functionality of brain stimulation devices using novel technological solutions informed by the neurophysiology and neurodynamics of the human brain. This extended functionality could enable new research applications and could allow increase of therapeutic effectiveness in clinical applications. For example, Dr. Peterchev has introduced a new class of efficient transcranial magnetic stimulation (TMS) devices that allow adjustment of the magnetic stimulus parameters over a wide range, which had not been possible with existing technology. These controllable pulse shape TMS (cTMS) devices could enable new methods for mapping neural parameters in vivo, as well as the optimization of stimulation paradigms for improved tolerability and stronger neuromodulatory effect in clinical applications. Besides his work on brain stimulation, Dr. Peterchev has also made contributions to the design of power supplies for microprocessors and portable electronics.
Dr. Peterchev received the A.B. degree in physics and engineering sciences from Harvard University and the M.S. and Ph.D. degrees in electrical engineering from the University of California, Berkeley. He completed postdoctoral training in TMS at Columbia University. While a student, Dr. Peterchev interned at the Portable Power Systems Group, National Semiconductor Corp., and worked at the Rowland Institute at Harvard, where he developed scientific instrumentation.
Dr. Peterchev received the 1999 Tau Beta Pi Prize from Harvard University and a 2001 Outstanding Student Designer Award from Analog Devices, Inc. He was awarded a Young Investigator Memorial Travel Award by the American College of Neuropsychopharmacology in 2007.
