Dr. Dario Rodrigues is one of the few thermal oncology physicists in the USA. His specialty is to treat cancer using focused heat generated by radio waves, a thermal therapy technique also known as hyperthermia, which is a potent enhancer of chemo- and radiotherapy. As a physicist, Dr. Rodrigues performs adjuvant hyperthermia treatments of pelvic, abdominal, and superficial tumors. He is also responsible for the treatment planning, thermal dosimetry, and quality assurance of the clinical hyperthermia equipment. In support of his clinical activities, his research involves the development of improved radiofrequency applicators for applying heat to tissue, noninvasive sensors to track temperature changes at depth, and new treatment planning strategies to improve thermal dose delivery. This research is accomplished with a combination of theoretical modeling, engineering development, and equipment performance evaluation with phantom, animal, and human patient subjects. One of Dr. Rodrigues most prominent research outcome was a noninvasive sensor that is able to safely monitor brain temperature during prolonged surgeries. This sensor was designed using microwave radiometry principles, a technique that is also used to measure the radiation from distant stars. A more recent topic of Dr. Rodrigues’ research is the development of a hyperthermia applicator to treat brain tumors, a target difficult to achieve due to the presence of the skull which reflects radio waves. To overcome the challenging structure of the human head, Dr. Rodrigues designed a 72-antenna phased array applicator that is able to target deep-seated brain tumors as demonstrated in a preclinical setting using advanced multiphysics numerical simulations.

A keyword that Dr. Rodrigues uses throughout his clinical and research activities is temperature. Accumulating evidence indicates that physiologic responses to heat affect the tumor microenvironment through temperature-sensitive checkpoints that regulate vascular perfusion, tumor metabolism, lymphocyte trafficking, inflammatory cytokine expression as well as innate and adaptive immune function. Understanding the influence of temperature in blood perfusion and in the immune system are paramount avenues of research that Dr. Rodrigues is actively pursuing. In one hand, the ability to understand the changes of blood perfusion under a thermal stress is key to develop accurate treatment planning and improved treatment delivery. On the other hand, the ability to fine tune temperature to elicit a specific immune response would represent a significant advance in cancer treatment by enabling new and more effective multimodality therapies that Dr. Rodrigues wishes to bring to the clinic.

Dr. Dario Rodrigues is an Assistant Professor of Thermal Oncology Physics at the University of Maryland and was recently elected Councilor of Engineering/Physics of the Society for Thermal Medicine.
