Dr. Smith attended Washington University (St. Louis) and received an A.B. in Physics and Mathematics in 1979. He worked as an exploration geophysicist for Gulf Oil Corporation (Houston, TX) from 1980-1985. Dr. Smith received his Ph.D. in 1989 from the University of California, San Diego in Earth Sciences, where he studied seismological imaging of the earth. From 1989-1992 he was a Postdoctoral Fellow in nuclear medicine physics at Duke University in Durham, NC, followed by Assistant Research Professor positions in the Department of Biomedical Engineering at Duke University (1992-1997) and in the Department of Radiology at Duke University Medical Center (1995-1997). Dr. Smith was a Physicist (1998-2000) and Staff Scientist (2000-1001) in the Nuclear Medicine Department of the Clinical Center, National Institutes of Health, Bethesda, MD. He then joined the Detector and Imaging Group in the Physics Division, Thomas Jefferson National Accelerator Facility in Newport News, VA as a Biomedical Imaging Physicist (2001-2007). Dr. Smith moved to the University of Maryland School of Medicine in 2007, where he is an Associate Professor in the Department of Diagnostic Radiology and Nuclear Medicine. He serves as the nuclear medicine physicist and provides clinical support, teaches radiology and nuclear medicine residents about nuclear medicine physics, and conducts research with a focus in quantitative cardiovascular imaging.
Dr. Smith's research interests are in the fields of nuclear medicine and PET instrumentation, imaging and data analysis. These include Monte Carlo modeling, image reconstruction, and pre-clinical and clinical applications. A particular interest is quantitative cardiovascular nuclear medicine imaging (PET and SPECT), and at the University of Maryland he has been involved in various projects investigating the use of PET and SPECT flow, viability and innervation images to aid electrophysiological ablation procedures to treat left ventricular tachycardia. Dr. Smith has led image reconstruction efforts for awake animal SPECT imaging and is involved in research for motion-corrected human brain PET imaging. He is the author or co-author of over 60 peer-reviewed publications and holds four U.S. patents.
