Lars Furenlid

Professor of Medical Imaging

Professor of Biomedical Engineering

Professor of Optical Sciences

Dr. Furenlid is a tenured Professor with appointments in the Department of Radiology and the College of Optical Sciences at the University of Arizona, and also a member of the Arizona Cancer Center and the Graduate Interdisciplinary Program in Biomedical Engineering. He trained as a physical chemist, but has since accumulated 25+ years of experience in molecular imaging, and the development and application of advanced instrumentation for x-ray and gamma-ray imaging, spectroscopy, optical imaging, and related methods for biomedical research. He is a founding member of the NIH-funded Center for Gamma-ray Imaging (CGRI), and is Co-Director and a project leader for the Center.

Dr. Furenlid has 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 mentors graduate students working towards masters and PhD degrees. He has a broad physics, chemistry, and structural biology background, and teaches graduate courses in the University of Arizona’s College of Optical Sciences on the physics and mathematics of imaging and spectroscopy. He also co-teaches a graduate course in the Biomedical Engineering/Cancer Biology programs on radiochemistry and molecular imaging methods in drug discovery. He currently serves as co-chair of the NIH SBMIT(10) study section which handles SBIR and STTR proposals in the biomedical imaging field.

Dr. Furenlid has 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. He works closely with and advises Masters and PhD students who carry out fundamental research and develop hardware technologies as part of their thesis/disseration projects.

As Co-PI and Co-Director of CGRI, Dr. Furenlid works closely with the CGRI project leaders and faculty members towards the successful completion of the specific aims in the core projects, collaborations, and service activities that constitute CGRI’s mission. He continues to lead the hardware-development program, working with students and staff to carry out experiments, acquire and analyze data, and prepare relevant manuscripts and presentations that describe study findings.

Dr. Furenlid has recently been awarded two research grants together with Drs. Mike King and George Zubal, of the University of Massachussetts and Z-Concepts, LLC, to develop specialized instrumentation to aid in the diagnosis and development of therapies for diseases of the human brain.
