Lab Directors
Richard T. Liu is an Associate Professor at Harvard Medical School and licensed clinical psychologist. He is the Director of Suicide Research in the Division of Child and Adolescent Psychiatry at Massachusetts General Hospital, and Director of Big Data Studies in the Depression Clinical and Research Program.
​
The primary focus of his research is on depression, suicide, and non-suicidal self-injury (NSSI) in childhood through emerging adulthood, with a particular emphasis on characterizing dynamic processes of risk underlying onset and recurrence of these clinical concerns. His programmatic interests lie in advancing our understanding of depression, suicide, and NSSI from who is at risk to how and when they are most at risk, thereby directly informing risk assessment strategies and yielding potential candidates for clinical intervention. His work in these and related areas have been published in journals such as Lancet Psychiatry, JAMA Psychiatry, JAMA Pediatrics, Psychological Bulletin, and American Psychologist. He is an Associate Editor of the Journal of Psychopathology and Clinical Science and Behavior Therapy, and he serves as a Consulting Editor at Clinical Psychological Science and the Journal of Clinical Child and Adolescent Psychology. He has also served on expert panels focused on preadolescent suicide at the National Institute of Mental Health.
Taylor A. Burke is an Assistant Professor at Harvard Medical School and licensed clinical psychologist. She is the Director of Pediatric Computational Health and Associate Director of Suicide Research in the Division of Child and Adolescent Psychiatry at Massachusetts General Hospital.
The primary aim of Dr. Burke’s research is to advance the prediction and prevention of self-injurious thoughts and behaviors (SITBs) among youth and young adults. Dr. Burke uses novel methodologies and computational approaches to improve the identification of individuals at risk to better intervene and prevent SITBs. She has published over 70 peer-reviewed articles and book chapters on the etiology of SITBs and related psychopathology. Dr. Burke holds a five-year NIMH career development award that focuses on using passive mobile sensing, adolescent sleep, and physical activity assessment, and advanced computational approaches to idiographic modeling to develop proximal risk models for increases in suicidal ideation. She also has other ongoing research supported by the American Foundation for Suicide Prevention and the NIMH focused on leveraging computer vision to enhance suicide risk screening in pediatric health care settings. Her program of research has been nationally recognized for its contribution to child and adolescent psychological science by her receipt of the Future Directions Launch Award by the Journal of Clinical Child and Adolescent Psychology.

Faculty
Dr. Amanda Collins
accollins@mgh.harvard.edu
Mass General Research Institute
CV
Amanda C. Collins is the Director of Digital Phenotyping and Therapeutics Research in the Depression Clinical and Research Program at Massachusetts General Hospital, and she is a Member of the Faculty in the Department of Psychiatry at Harvard Medical School.
Dr. Collins’ research primarily focuses on reward dysfunction as a transdiagnostic mechanism underlying the etiology and maintenance of psychopathology, including depression, anxiety, and substance use disorders. The two areas of her research focus on: (1) the application of advanced statistical methods to predict changes in psychopathology and (2) the development and testing of both in-person and digital interventions. She is particularly interested in bridging these two areas of research by using advanced methods to understand what interventions work best and for whom, with the overall goal of developing more personalized interventions to treat reward dysfunction transdiagnostically. Dr. Collins utilizes a multimodal approach, including self-reports, experimental paradigms, ecological momentary assessments, and passive sensing, to investigate the dynamic and heterogeneous nature of psychopathology. She also has extensive experience with longitudinal data analysis, including multilevel and time-varying vector autoregressive modeling, mixed-effects modeling, network analysis, and machine learning to investigate how reward dysfunction changes over time and influences the course, severity, and treatment of psychopathology. Her work has been funded by the National Institute on Drug Abuse to develop and evaluate digital interventions for co-occurring disorders.
Postdoctoral Fellows
Yeonsoo Park is a postdoctoral fellow at MABL. He is interested in the biopsychosocial risk factors related to suicidal thoughts and behaviors and has been recently examining how basic cognitive functions may influence decision-making in suicide. Yeonsoo earned his Ph.D. from the University of Notre Dame, where he studied proximal risk factors of suicidality using ecological momentary assessment and stigma surrounding disclosure of self-harm under the mentorship of Dr. Brooke Ammerman. Yeonsoo completed his clinical internship at McLean Hospital and has been trained in CBT, ACT, and DBT. Prior to completing his doctorate, Yeonsoo earned his MA in counseling and clinical psychology from Sogang University in South Korea, and his BA in psychology from New York University.
Clinical Psychology Interns
Ana Sheehan
CV
Ana's research explores short-term factors associated with risk for suicide including daily fluctuations in impulsivity and mood, particularly in the context of parent-adolescent dyadic relationships. In addition, Ana’s work places an emphasis on understanding trends and risk for suicide among traditionally underserved populations. Ana is in her final year of her PhD program at the University of Delaware under the mentorship of Naomi Sadeh and is currently completing her clinical internship at Massachusetts General Hospital/Harvard Medical School within the child track. Ana’s research has been supported by the National Science Foundation and she is a PEO Scholar Awardee.
Rachel Walsh
CV
Rachel is currently completing her predoctoral clinical internship at Massachusetts General Hospital/Harvard Medical School. She is a sixth-year doctoral student at Temple University, where she worked in the Mood and Cognition Lab under the mentorship of Dr. Lauren Alloy. Her research seeks to improve our understanding of risk factors for mood disorders and particularly suicidal thoughts and behaviors. Specifically, Rachel is interested in the intersection of sleep, circadian rhythms, and mood symptoms, examining whether disturbances in sleep and circadian rhythms contribute to the development of depression and suicidal ideation. Rachel’s program of research has been supported by the National Science Foundation and the PEO Scholar Award. She has received training in CBT, DBT, and attachment-based family therapy (ABFT). Rachel has completed clinical practicums in pediatric behavioral sleep medicine and cognitive behavioral therapy for insomnia. Prior to pursuing her doctorate, Rachel earned her bachelor’s degree from Carnegie Mellon University and completed post-baccalaureate research assistantships at the National Institute of Mental Health and Brown University.
