I received my PhD in Agricultural Engineering at the Technion, Israel Institute of Technology in Haifa, Israel in 1999. I then spent four years as a post-doctoral fellow at the University of Maryland Biotechnology Institute in Baltimore, MD and two years as an Imaging Sciences Training Program fellow at the Clinical Center, National Institutes of Health. For the next six years I was a staff scientist at the Department of Radiology and Imaging Sciences at the NIH Clinical Center, and headed the focused ultrasound program. Before joining the faculty at the University of Maryland, I was a tenure-track, Associate Professor for three and a half years at the Department of Biomedical Engineering at Catholic University of America in Washington, DC.

Research Interests

Dr.  Frenkel’s research interests are rooted in a comprehensive understanding of the mechanisms by which ultrasound energy interacts with biological tissues at the macroscopic, cellular and sub-cellular/molecular level. With this knowledge, he and his colleagues have proposed new therapeutic ultrasound applications, as well as ways to improve existing ones in the fields of oncology, cardiovascular disease, physical therapy and cellular homing. A particular focus of his research has involved noninvasively enhancing drug and gene delivery through the skin, in to solid tumors, and in to acute and chronic blood clots.

Dr. Frenkel’s research techniques include mathematical modeling and simulations, as well as multiple modality imaging - from electron microscopy to optical and bioluminescent imaging, ultrasound, and MRI. My projects typically encompass theoretical, mechanistic, and preclinical translational studies, and involve the development of novel in vitro platforms and preclinical models, as well as image-guided focused ultrasound devices.

Dr. Frenkel is a member of the Experimental Therapeutics Program within the University of Maryland Marlene and Stewart Greenebaum Cancer Center Program in Oncology. Experimental Therapeutics researchers collaborate with both basic and clinical research investigators, focusing on the rapid transfer of knowledge from the laboratory to the clinic. Dr. Frenkel’s research centers on developing novel ways that therapeutic ultrasound can be employed for the treatment of solid tumors.
