I joined the University of Bridgeport (UB) in the fall of 2016, following my postdoctoral work at the Geisel School of Medicine at Dartmouth College, where I studied the cytotoxicity of hyperthermia induced with iron oxide magnetic nanoparticles and alternating magnetic fields. I completed my doctoral work at the Thayer School of Engineering at Dartmouth College. I was also a Master of Engineering Management (MEM) student and a PhD Innovation Fellow, which enabled me to gain experience relating to intellectual property and the commercialization/clinical adaptation of technology.

The research laboratory in which I completed my PhD and postdoctoral research, was part of the Dartmouth Center of Cancer Nanotechnology Excellence (DCCNE). The DCCNE, funded by the NCI through a Center of Cancer Nanotechnology Excellence (CCNE) grant, sought to bring a magnetic nanoparticle-based cancer therapeutic into the clinic. This large and multi-disciplinary effort required expertise in material science, protein engineering, immunology, and medical imaging. In this environment, I was able to develop my research interests which include nanoparticle-cancer therapeutics, medical devices, cancer biology, immunology, biomaterials and the development of meaningful biologic models and experimental prototypes.

My research efforts at UB have built off this prior experience and motivated me to work towards a better understanding of the interaction between nanomaterials, ionizing radiation and hyperthermia. It has been shown that ionizing radiation, combined with hyperthermia, can result in a greater therapeutic ratio in the treatment of cancer than radiation or hyperthermia alone. Recent work has also shown that magnetic nanoparticles (MNP) may have potential as radiation sensitizers. When MNP are exposed to an alternating magnetic field (AMF) a localized hyperthermia can be induced. Hence, the presence of MNP within the tumor may have two independent, but complementary modalities of therapeutic enhancement. Despite this potential, whether or not there are significant benefits or differences that exist as a result of the intracellular uptake of MNP remains an unresolved question in the field. The current efforts of my lab are aimed at a better understanding of the mechanism of cellular uptake of MNP, why some cells within a population take up the MNP more readily than others, and how this affects the cytotoxicity of the therapy. Additional research areas include development of diagnostic sensors for the detection of diseases, which would be both affordable and appropriate for use in remote regions, as well as sensors for children with severe allergies.

I enjoy collaboration and hope to continue to work in the field of medical devices with scientists from different areas of expertise. The role I played within the Surgical Research Labs has exposed me to many areas of research, including nanotechnology, immunology and medical device design. I have a strong background in the development of meaningful biologic models (in vitro, ex vivo and in vivo) and experimental prototypes which are necessary for translation into the clinic. I have a unique perspective as a result of my MEM training, Innovation Fellowship and my work in industry, as well as my experience in developing a clinical trial. I am enjoy working with students to develop solutions using my training and experience in the multidisciplinary fields of business, medicine and engineering.
