As a member of Dr. Kate O'Connor-Giles’ Lab laboratory at Brown, Jennifer Dumouchel focused her research ona newly identified regulator of synaptic growth and function, TRMT9B. The lab uses genetic, transcriptomic and biochemical approaches in Drosophila to explore how TRMT9B promotes nervous system development and function, with a focus on its role in stress resistance. On May, 27th, 2025 Jennifer successfully defended her PhD thesis entitled “Role of tRNA methyltransferases in nervous system development and function.” Afterward, Jennifer enjoyed a celebration on campus with her Advisor, Dr. Kate O'Connor-Giles, and Brown students, faculty and staff. Jennifer’s family and friends also traveled to Brown as well so they could proudly celebrate this tremendous milestone in her life. Congratulations, Dr. Dumouchel!
