Krishna Nayak of the Ming Hsieh Department of Electrical Engineering and Viterbi School of Engineering has been promoted to Associate Professor with tenure, effective immediately. Krishna received B.S. degrees in electrical engineering, computer science, and applied mathematics from Florida State University in 1995, and received M.S. and Ph.D. degrees in electrical engineering from Stanford University in 1996 and 2001 respectively. He was a lecturer and research associate at Stanford from 2001 through 2003, and joined the Ming Hsieh EE faculty in 2003 as assistant professor. He holds joint appointments in the USC Departments of Medicine, Radiology, and Biomedical Engineering.
Krishna's research is in the broad field of biomedical imaging, particularly magnetic resonance imaging (MRI). His research concentrates on several related themes, including: (1) novel signal processing methods to improve image quality, resolution, and signal-to-noise ratio by compensating for high-order imperfections in the scanning systems; (2) improving the speed and efficiency of MRI reconstruction; and (3) extending the applicability of MRI by developing new imaging techniques that do not require contrast agents.
Krishna is also known for his work on new applications of MRI, including: (1) techniques for assessing the coronary arteries and myocardial perfusion, and characterizing blood flow dynamics near atherosclerotic plaques; (2) techniques to quantify body fat distribution for studies of obesity and the regulation of fat accumulation; and (3) real-time imaging of the human vocal tract and upper airway for research in speech production, vocal system modeling, and sleep apnea.
Alexander (Sandy) Sawchuk, Systems Chair of the Ming Hsieh Department of Electrical Engineering said, "our department joins me in congratulating Krishna on his promotion and its acknowledgment of his academic and research accomplishments!"
