Brittany Deanna Kurita Gratreak
MD/PhD Student

Britt (she/her) graduated from Portland State University in 2016 with a Bachelor of Science in Biology and completed an honors research thesis in extreme virology under the mentorship of Dr. Kenneth Stedman in the Center for Life in Extreme Environments. After graduation, she worked as the lab manager of Dr. David Ellison’s nephrology and hypertension laboratory at Oregon Health and Science University, studying mechanisms of kidney damage caused by organ transplant drugs that modulate the immune system. She entered the MD/PhD program at the University of Arizona College of Medicine - Tucson in 2019 and joined the Doyle Lab in 2021 as a graduate student in Neuroscience. In the lab, Britt is researching the immune response to recurrent strokes that are characteristic of sickle cell disease. For fun, she likes hanging out with her strange cats (Hex, Wernicke, Broca, and Korsakoff), cycling, building blanket forts, and playing nerdy video/board games. Oh, and she screams in capital letters on Twitter a lot.
