Neville Gai received his Bachelor's degree in Electrical Engineering from the Indian Institute of Technology, Bombay (Mumbai), Master's degree in Electrical & Computer Engineering from the State University of New York, Buffalo, and his doctorate in Biomedical Engineering from the University of Pennsylvania, Philadelphia. After a short stint as a Research Associate at Weill Medical College of Cornell University, New York, Neville joined General Electric Medical Systems (GE Healthcare), Waukesha, WI as an MR Applications Development Engineer where he was responsible for technical developments in high resolution and real-time cardiac imaging as well as optimization techniques for high field body MR imaging. He is currently a Staff Scientist in the Radiology Department at the NIH Clinical Center supporting clinical scanning and research. His first author publications reflect his wide variety of interests related to MR physics in general. In particular, these include pulse sequence design/enhancements and simulations for improved contrast, speed, selectivity in MR imaging applications; quantitative cardiac and neuro MR; cardiac diffusion imaging; artifact reduction; contrast agent free quantitative brain perfusion techniques based on arterial spin labeling.
