Karen Christopher finished her doctoral program exploring the effects of early-life stress using behavioral and molecular biology techniques under the guidance of Dr. K. Emmanuvel Rajan. She joined the Chudasama lab in November 2022 as a postdoctoral fellow. She is interested in working on the developmental neuroanatomy and cognitive functions of septo-hippocampal pathway.
