Principal Investigators


Dr. Richard Liu

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 at Journal of Psychopathology and Clinical Science and Behavior Therapy, and he serves as a Consulting Editor at Clinical Psychological Science and 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.

Postdoctoral Fellows


Lauren Haliczer

Lauren is a Postdoctoral Fellow in the MABL. Her fellowship is supported by an NIMH F32 award, in which she will explore negative social experiences (e.g., exclusion/rejection) and self-criticism as predictors of imminent risk for suicidal thoughts and behaviors in the lab and everyday life. Lauren earned her Ph.D. from the University of Massachusetts Amherst, where her research spanned the areas of suicidal and nonsuicidal self-injury, borderline personality disorder, emotion dysregulation, and dialectical behavior therapy (DBT) under the guidance of Dr. Katie Dixon-Gordon. Lauren completed her clinical internship at the Alpert Medical School of Brown University, and has received clinical training in CBT and DBT to treat a range of mood, anxiety, and personality disorders in inpatient, partial hospital, and outpatient settings. Prior to completing her doctorate, Lauren earned her MA in clinical psychology from Teachers College, Columbia University, and her BS in psychology from Tulane University.

Naoise Mac Giollabhui

Naoise is a postdoctoral fellow at the Depression Clinical and Research Program. His research investigates why cognitive functioning is disrupted in depression, why these cognitive difficulties persist in remitted depression and treatment options available to patients to address this debilitating symptom of depression. He is particularly interested in understanding the role played by the immune system in the etiology of depression and cognitive dysfunction. His program of research has been supported by the NIH and the American Psychological Foundation and has been nationally recognized through awards from the American Psychological Association and the Society of Clinical Psychology. He currently serves on the editorial board of Brain, Behavior, and Immunity
