Hyesun “Sunny” Jang is a staff scientist at the J. Craig Venter Institute, supervised by Dr. Marcelo Freire. With a background as a veterinarian, Dr. Jang is interested in developing host-directed anti-viral strategies against diverse zoonotic viruses.
Dr. Jang received her doctor of veterinary medicine (DVM) and master of science (MS) degrees from Chungbuk National University in South Korea (2005-2012). During the eight-year-training in Korea, Dr. Jang focused on developing novel strategies to diagnose and control avian diseases. In 2013, Dr. Jang moved to United States to pursue a PhD at Ohio State University (2013-2017) followed by postdoctoral training at the University of Georgia (2018-2021). During her PhD and postdoctoral training, Dr. Jang’s research interests led her to apply her knowledge of host-pathogen interactions to improve vaccines against zoonotic avian influenza viruses.
With her expertise in virology and veterinary medicine, she has been actively engaged in diverse projects to evaluate candidate prophylactics/therapeutics against the novel SARS-CoV-2 virus. Dr. Jang has also collaborated with pioneers in a wide range of fields, inspiring her to expand her research to include high-throughput analysis on biofluids. Dr. Jang joined JCVI to apply omics tools in the investigation of host-pathogen interactions. She believes that a better understanding of host-pathogen interaction will lead to the development of innovative prophylactic/therapeutic measures against rapidly evolving zoonotic viruses.
