Post-doctoral Fellows & Junior Faculty


Post-doctoral Fellow

Dr. Peckham (he/him) is an NIMH-funded F32 post-doctoral fellow in the CARE Lab at McLean Hospital and a clinical fellow in psychology in the Department of Psychiatry at Harvard Medical School. His research focuses on the relationship between cognitive functioning and emotion regulation in mental illness, particularly bipolar disorder. In addition, he studies cognitive mechanisms underlying mood-based impulsivity across disorders, as well as the development of new treatments for this type of impulsivity.

Dr. Peckham completed his doctoral training at the University of California, Berkeley, where he conducted research in Dr. Sheri Johnson’s Cal Mania program. His graduate research was partly supported by an institutional training grant in neuroscience and treatment development from the NIMH, and his dissertation research on cognitive training for impulsivity was funded by the Society for a Science of Clinical Psychology.


Post-doctoral Fellow

Dr. Kuckertz (she/her) is a postdoctoral fellow at the McLean Hospital OCD Institute. Her research interests are in mechanisms of treatment for OCD and anxiety disorders, including traditional interventions such as exposure and response prevention as well as novel cognitive bias modification (CBM) programs. Dr. Kuckertz was awarded a Corneel Young Investigator Award under the mentorship of Dr. Courtney Beard and Dr. Christian Webb to use machine learning to examine mechanisms of exposure and response prevention for alleviating OCD and depression symptoms. Dr. Kuckertz completed her PhD at the San Diego State University/UC San Diego Joint Doctoral Program in Clinical Psychology, where she primarily studied cognitive biases and their modification in anxious adults, children, and their parents. 


Junior Faculty

Dr. Falkenstein (she/her) is an instructor in psychology in the Department of Psychiatry at Harvard Medical School and the administrative director of the Office of Clinical Assessment and Research at the OCD Institute at McLean Hospital. Dr. Falkenstein’s research focuses on mediators and moderators of treatment response in obsessive compulsive related and anxiety disorders. She has received funding from the International OCD Foundation and Harvard Medical School (Kaplen Fellowship and Livingston Award) for her work on cognitive mechanisms of treatment response, as well as prediction and prevention of suicidality in individuals with these disorders.
