Doctoral Students

Samantha Hoffman

Sam is a second-year graduate student in the SDSU/UCSD Joint Doctoral Program in Clinical Psychology under Dr. Charles Taylor and Dr. Murray Stein. Her research interests are focused on identifying risk and resilience factors associated with mood, anxiety, and stress disorders following trauma, particularly posttraumatic stress disorder; and, how such associations can inform the development and optimization of interventions.

Maria Kryza-Lacombe

Maria is a PhD Candidate at the San Diego State University/UC San Diego Joint Doctoral Program in Clinical Psychology. Her overarching research focus is clinical translation. To this end, she uses neuroimaging and neuropsychological tools to identify neural, cognitive, and emotional factors that promote well-being. She is currently examining these factors in adults with depression and/or anxiety under Charles Taylor's mentorship at UC San Diego, as well as in youth with varying levels of irritability under Jillian Lee Wiggins’ mentorship at San Diego State University. Her long-term goal is to contribute to mechanism-based prevention and intervention development to foster well-being and resilience across the lifespan.
