About Afua

Afua graduated from the University of Washington Bothell in 2020 with a Bachelor of Science in Biology, and a minor in Neuroscience. Prior to joining the Simpson Lab, Afua spent a year and a half working night shifts as a Lab Assistant and later a Technician at Labcorp on the Swedish Cherry Hill campus.

Working on the heels of the pandemic, Afua gained significant experience in the healthcare field by doing PCR testing for COVID-19 and other infectious diseases. Most recently, she worked in biotech as an Associate Scientist for Nexelis doing immunology tests to analyze drug efficacy. Her research interest is fueled by a passion for science and its clinical significance. Afua was on the pre-med path at UW-Bothell, and she hopes to continue pursuing that journey to achieve her MD and PhD.

In her free time, Afua enjoys exploring the Pacific Northwest, hiking, road trips and spending time with her family and friends.
