Akansha Singh, Ph.D., Research Assistant Professor
Dr. Singh earned her Ph.D. degree in immunology from the National Institute of Immunology in New Delhi, India, in 2020. Her research focused on designing an artificial tissue substitute to be used for organ regeneration using natural and organic polymers. She completed a fellowship at the Ross Tilley Burn Centre, Sunnybrook Health Sciences Centre, University of Toronto, Canada, where she advanced her research on artificial dermal substitutes.
Dr. Singh then completed her postdoctoral training in the Department of Physiological Sciences at Oklahoma State University where she applied her knowledge of organic polymers to develop multimodal particles for enhanced antigen-presenting cell activation. She subsequently worked as a research scientist and research assistant professor at OSU, focusing on improving clinical outcomes of immunotherapies for cancer treatment. She was a part of the canine clinical trial team at OSU where she treated canine cancer patients with therapeutic ultrasound and immunological cell-death inducing nanoparticles.
Dr. Singh has extensive experience with therapeutic ultrasound, cancer immunology, polymeric nano- and micro-particle formulations, biochemistry, molecular biology, and protein structure and function. Her current research is focused on understanding molecular and immunological variations among cancer patients, as well as designing a treatment regime tailored to patient immune and demographic profiles.
Faraz Chamani, Ph.D., Postdoctoral Researcher
Dr. Faraz Chamani earned his Ph.D. in Electrical and Computer Engineering from Kansas State University in 2023. His research focused on in vitro measurement and mathematical modeling of hyperthermia-induced bioeffects in pancreatic cancer cells, contributing to the development of modeling tools for predictive treatment planning of thermal therapies and furthering understanding of the effects of energy-based interventions that involve perturbation of tissue temperature.
Dr. Chamani gained industry experience as a R&D Radiofrequency Engineer at Varian Medical Systems in Austin, Texas. During his one-year tenure, he expanded his technical engineering skills and computational modeling expertise, particularly in Finite Element Analysis (FEA) in minimally-invasive thermal ablation for cancer treatment. During this time, Dr. Chamani contributed to the development of a microwave thermal ablation system for the treatment of liver tumors.
With extensive research and industry experience in energy-based thermal ablation modalities, Dr. Chamani has published his work in peer-reviewed journals. Currently, as a post-doctoral researcher, his work focuses on optimizing High-Intensity Focused Ultrasound (HIFU) as a novel non-invasive therapeutic approach for cancer treatment. This includes both thermal ablation and non-thermal histotripsy techniques, with a particular emphasis on designing personalized treatment protocols for canine cancer patients.
