James C. Lacefield received B.S.E. and Ph.D. degrees
in biomedical engineering from Duke University in 1992 and 1999, where he was an NSF/ERC
Predoctoral Fellow in the Center for Emerging Cardiovascular Technologies. From 1999
through 2001 he served as a Visiting Research Associate of the Diagnostic Ultrasound Research
Laboratory in the Department of Electrical and Computer Engineering at the University of
Rochester. His work at the University of Rochester was funded in part by the 2000-01 Acoustical
Society of America Frederick V. Hunt Postdoctoral Research Fellowship in Acoustics.
Dr. Lacefield joined the University of Western Ontario in
2001 and is currently an Associate Professor jointly appointed to the Department of Electrical and
Computer Engineering and the Department of Medical Biophysics. He is also a faculty member
of Western's Biomedical Engineering Graduate Program, an Associate Scientist of the Imaging
Research Laboratories at Robarts Research Institute, and a Mentor in Western's CIHR Strategic
Training Program in Cancer Research and Technology Transfer. His research activities address
physical acoustics and signal processing aspects of biomedical ultrasound imaging, with an
emphasis on applications of ultrasound to cancer and cardiovascular research.
Dr. Lacefield is a member of the Acoustical Society of
America, the American Society for Engineering Education, the Institute of Electrical and
Electronics Engineers, and the Association of Professional Engineers of Ontario.
Key Research Questions
-
How can ultrasound imaging most effectively contribute to basic (“preclinical”) research in cancer,
cardiac, and vascular disease?
-
Will hypotheses about ultrasound imaging physics that are generated through computational modeling
lead to improved methods for clinical and preclinical imaging?
