Select from the following:

Dr. Bhavna Chohan received her PhD (Virology) from University of Washington and MSc degree from London School of Hygiene & Tropical Medicine, UK. She has worked with HIV/STI research since 1993, for collaborative research projects with UW/Nairobi in Kenya. After her graduate studies at UW under the mentorship of Dr. Overbaugh, she returned to Nairobi, Kenya in 2007, where she established molecular virology research laboratory and transferred technology of HIV early infant diagnosis and HIV drug resistance testing. Dr. Chohan's broad goals are to establish and implement quality research on HIV transmission studies to improve health outcomes in Kenya and build a resource of well-trained and qualified laboratory scientists in the country. Currently, she continues to serve as Laboratory Director for UW collaborative research studies in Nairobi and conducts funded research studies as lead and co-investigator for NIH and local (Kenya) funded studies, and supervises, trains and mentors students and junior scientists. Dr. Chohan is also a member of National AIDS & STI Control Program in Kenya and continues to attend HIV Prevention and PrEP Technical Working meetings and provide input on national guidelines for ART and PrEP implementation. Her research interests are focused on HIV transmission and drug resistance studies and to implement Laboratory strengthening and capacity building in the low and middle income (LMIC) countries in Africa.
