Lars R. Furenlid, PhD

Harry H. and Catherine C. Barrett Endowed Chair in Optical Sciences for Cancer Imaging
Vice Chair of Research
Professor, Medical Imaging and Optical Sciences
Professor, Biomedical Engineering
Director, Center for Gamma-Ray Imaging

I am a tenured Professor with appointments in the Department of Medical Imaging and the College of Optical Sciences at the University of Arizona, a joint appointment in Biomedical Engineering, and am also a member of the Arizona Cancer.  I am a physical chemist/physicist with 24 years of experience in molecular imaging and the development and application of advanced instrumentation for x-ray and gamma-ray imaging and spectroscopy, optical imaging and spectroscopy, and related methods for biomedical research.  I am a founding member and Contact Principal Investigator and Director of the NIH-P41-funded Center for Gamma-ray Imaging (CGRI), and have been a project leader for the Center since its inception in 1999.    

 I have served as principal investigator, project leader, or co-investigator on federally- and industry-funded research projects including grants from the NCRR, NCI, and NIBIB institutes, and mentor graduate students working towards Masters and PhD degrees.  I have a broad physics, chemistry, and structural biology background, and teach graduate courses in the University of Arizona’s College of Optical Sciences on the physics and mathematics of imaging and spectroscopy.  I also co-teach a graduate course in the Biomedical Engineering/Cancer Biology programs on radiochemistry and molecular imaging methods in drug discovery.  I currently serve as co-chair of the NIH SBMIT(10) study section, which handles SBIR and STTR proposals in the biomedical imaging field.

I have special expertise in the techniques required to develop and apply advanced x-ray and gamma-ray detectors, and commissioned SPECT, PET, and CT imaging systems.  This includes the physics of scintillation and solid-state detectors, methods of optics, pulse-processing electronics, digital data acquisition, and data inversion/assessment/reconstruction with a variety of computational methods.   I work closely with and advise Masters and PhD students who carry out fundamental research and develop theory and hardware technologies as part of their thesis/dissertation projects.
