About

Valentyn Stadnytskyi is a highly educated and experienced physicist with a passion for research and development. He earned his PhD in Physics from Purdue University in 2017, where he specialized in the field of biophysics. Prior to that, he received his Master of Science in Physics & Optical Science from Taras Shevchenko National University of Kyiv in 2011. After completing his graduate studies, Valentyn worked as an ORISE Fellow at the US Food and Drug Administration, where he focused on developing methods for measuring air pollution and its health effects. He then transitioned to a position as a physicist at the FDA, where he continued his work on air pollution and also contributed to the development of new technologies for detecting and monitoring harmful substances in food and drugs. Valentyn's expertise in biophysics and his interest in improving public health led him to a research fellow position at the National Institutes of Health. There, he worked on projects involving the use of optical techniques to study biological systems, with the goal of finding new ways to diagnose and treat diseases. Throughout his education and career, Valentyn has published numerous peer-reviewed articles and has presented his research at various conferences. He is a dedicated and driven scientist, always seeking new ways to apply his knowledge and skills to make a positive impact in the world.
