Christopher Beevers, Ph.D., director of the Mood Disorders Laboratory, received his doctorate in adult clinical psychology from the University of Miami in 2002. He completed his internship and post-doctoral training at Brown Medical School in Providence, Rhode Island and joined the psychology department at the University of Texas in January 2005. He has received the President’s New Researcher Award from the Association of Behavioral and Cognitive Therapy and was a Beck Scholar at the Beck Institute for Cognitive Therapy and Research. He is currently Associate Editor at Clinical Psychological Science and a member of several editorial boards for leading journals in his research area, including the Journal of Abnormal Psychology and Cognitive Therapy and Research. Dr. Beevers’ primary research interest focuses on the cognitive etiology and treatment of major unipolar depression. He is very interested in using experimental psychopathology methods to identify factors that maintain depression and translating these findings into effective interventions for depression and related psychopathology (e.g., anhedonia, negative affect). 

Research Faculty/Post-Docs

Jason Shumake, Ph.D.

Biostatistician / Research Assistant Professor
E-mail: shumake@utexas.edu

Jason Shumake received his doctorate in psychology from the University of Texas in 2004, with a concentration in behavioral neuroscience and a supporting portfolio in statistics and computational modeling, and he completed his postdoctoral fellowship at the Leibniz Institute for Neurobiology in Magdeburg, Germany, in 2007. Dr. Shumake’s primary research interest is building models from longitudinal data sets to classify and predict behavior and responses to interventions. He is excited by the advancement of personalized medicine through data science, which he believes is critical for translating prediction research into individualized treatment recommendations. He is particularly interested in using statistical and machine learning algorithms to search for novel combinations of genetic, neural, and behavioral features that predict treatment response. His current projects involve mining anatomical and functional brain imaging data, eye tracking data, and psychometric data from depressed individuals to predict longitudinal mood changes that occur both naturalistically and in response to antidepressant medication and cognitive therapy.

Peter is a postdoctoral fellow with the Whole Community Whole Health grand challenge initiative of the University of Texas at Austin. With mentors and collaborators in psychology, medicine, and electrical engineering, he is working to create new and more effective methods to mine personal sensing data from smart, mobile, and wearable devices for mental health inference and intervention. Before joining UT Austin, he completed a doctoral degree in systems engineering from the University of Virginia, where he focused on the theories and techniques of processing social signals data captured in cyber-human systems such as physical proximity encounters and online social networks. He has strong interest in using sensing technology to measure the ways people engage in social interactions and respond to social stimuli as well as using machine learning to uncover their connections with health, cognitive, and performance outcomes.

Kimberly Ray, Ph.D.

Research Scientist
E-mail: kimray@utexas.edu

Kimberly Ray, PhD is a Research Scientist working under the direction of David Schnyer, PhD and Christopher Beevers, PhD. She earned a bachelors degree in physics from Texas Lutheran University, and a PhD in Radiological Sciences with an emphasis on human neuroimaging from the University of Texas Health Science Center in San Antonio.  She also completed a postdoctoral fellowship at the University of California in Davis under the direction of Dr. Cameron Carter. Her research interests involve using functional magnetic resonance imaging (fMRI) and other imaging modalities to elucidate the functional and structural architecture of the human brain and examine how brain networks flexibly reorganize to efficiently carryout a given goal-directed task.

Graduate Students

Michael Mullarkey, M.A.

6th Year Doctoral Student (on internship)
Email:  mullarkey.mike@gmail.com

Michael completed a BA/MA in Clinical Psychology at American University. He did intensive, in-home clinical work with youth and their parents in Maryland and Virginia before moving to North Carolina to do restorative justice work. He also worked in a lab at the University of North Carolina-Chapel Hill’s Medical School, where he analyzed data from self-compassion and mindfulness interventions for youth.

Michael’s research at UT-Austin primarily involves taking a symptom-level approach to depression. His research focuses on identifying which symptoms might be most central to depression, evaluating which symptoms are most related to other important outcomes in people’s lives, and developing brief, accessible interventions to target particular symptoms. To investigate these questions, he often uses advanced analytic techniques such as network analysis and machine learning. His current projects are primarily focused on translating symptom-level findings into online, scalable, and targeted interventions for individual depression symptoms. Michael is currently completing his clinical internship at Stony Brook University. To read more, see Michael’s website: https://michaelmullarkey.me/

Derek Pisner, M.A.

5th Year Doctoral Student in Cognitive Neuroscience
Email: dpisner@utexas.edu

Derek joined the Mood Disorders Lab and Schnyer Cognitive Neuroscience Lab in 2016. He studied Philosophy and Mathematics at the University of Virginia in 2011, and subsequently completed a post-baccalaureate degree in Psychology at the University of California, Berkeley. He has extensive experience analyzing diffusion MRI (dMRI) and functional MRI (fMRI) data, along with a particular expertise in the study of brain networks.

Currently, part of Derek’s research includes developing new methods and software for integrating neuroscience, data science, and clinical research. From a basic science perspective, he is also studying the neural mechanisms of rumination and negative attention bias in depression. In the long-term, Derek further hopes to explore how multidimensional phenotypes based on person-specific data (e.g. dynamic behavioral, demographic, genetic, and neural topographic) might be translated into actionable diagnostic and treatment information for clinicians.

Mary (Molly) Eileen McNamara, B.A.

3rd Year Doctoral Student
Email: molly.mcnamara@utexas.edu

Mary (Molly) received her bachelor’s degree in Human Biology from Stanford University. While at Stanford, she worked in the Mood and Anxiety Disorders Lab on research investigating both the use of interpretation bias training with adolescents, as well as how parenting styles might affect neural development in teens with varying levels of suicidal ideation. After graduation, Molly worked as a project coordinator in the Golden Bear Sleep and Mood Research Clinic at UC Berkeley, launching a randomized controlled trial of a novel, adjunctive intervention designed to support patient memory for treatment.

Molly joined the Mood Disorders Laboratory as a doctoral student in 2018. She is interested in how cognitive biases and cognitive control might contribute to differences observed in depression both intra and inter-individually. She is also interested in the ways that translational research can help identify and influence treatment targets, as well as inform more personalized treatment planning.
