Biostatistician \/ Research Assistant Professor

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\u2019s 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.<\/p><\/div><\/div>\n<\/div>\n\n\n\n

Rochelle (Shellie) Stewart, Ph.D.<\/strong><\/h3>Post-Doc | Email:\u00a0rochelle.stewart@utexas.edu<\/a>

Post-Doctoral Research Fellow

Rochelle (Shellie) Stewart received her B.A. in Psychology from The University of Texas at Austin. Following graduation, she worked as a project coordinator in the Mood Disorders Laboratory, managing clinical research on the cognitive and neurobiological mechanisms of depression. Shellie went on to earn her Ph.D. in Clinical Psychology from Florida State University, where her graduate training emphasized advanced quantitative methods and multimethod, multilevel approaches to studying psychopathology. She completed her predoctoral clinical internship at the Michael E. DeBakey VA Medical Center in Houston before returning to the Mood Disorders Laboratory as a postdoctoral fellow.
Shellie\u2019s research seeks to better characterize psychological processes relevant to psychopathology through the use of diverse measurement and analytic approaches. Her previous work has examined the structure and measurement of transdiagnostic dimensions of psychopathology and their associations with neurophysiological and behavioral indicators. Her current research focuses primarily on depression and seeks to understand how cognitive and behavioral processes unfold dynamically over time. In particular, she is interested in using eye tracking to characterize the temporal dynamics and underlying patterns of attention to emotional information. More broadly, Shellie is interested in developing and applying novel approaches to uncover clinically relevant psychological processes that may be difficult to capture using traditional measures and analytic methods.<\/p><\/div><\/div>\n<\/div>\n\n\n\n

Claire Landon, B.S.<\/h3>Email:\u00a0clandon@utexas.edu<\/a><\/span>

Claire received her bachelor\u2019s degree in Psychology with a minor in Mathematics from the University of Miami in 2021. After graduation, she worked as a Registered Behavior Technician, providing Applied Behavior Analysis therapy to children on the autism spectrum. She then worked as the lab manager for Dr. Aaron Heller\u2019s Miami Affective Neuroscience And Translational Experimental Enterprise lab, where she managed several studies using ecological momentary assessment and multimodal data collection, including repeated self-reports, GPS tracking, audio recordings, and physiological data collected via wearable devices.

Claire joined the Mood Disorders Laboratory in 2025. Her research interests focus on the cognitive and emotional processes underlying the development and maintenance of depression and anxiety. She is particularly interested in how biases in learning and memory contribute to the formation, persistence, and updating of negative beliefs and expectations.<\/p><\/div><\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n

Andrew\u00a0graduated from Claremont McKenna College in 2015 with a B.A. in Psychology and Philosophy. After graduating, he was a research coordinator for Mark Powers, Ph.D., and Jasper Smits, Ph.D., at The University of Texas at Austin where he coordinated two randomized controlled trials examining the efficacy of virtual reality as treatment for arachnophobia and as a pain management intervention for hospital patients at Dell Seton Medical Center. At UT he also assisted in projects examining treatments for social anxiety, PTSD, panic attacks, and smoking cessation, with an emphasis on CBT\u00a0and exercise augmentation. Andrew then worked as a clinical research coordinator for Anne Richards, M.D., M.P.H., at UCSF and the San Francisco VA Medical Center coordinating a randomized placebo-controlled clinical drug trial of doxazosin for PTSD nightmares, sleep disturbance, and overall PTSD symptoms.

Andrew joined the Mood Disorders Laboratory in 2019. He is deeply interested in improving treatments for depression with a focus on behavioral change interventions that target exercise, sleep, diet, and social engagement. He is also interested in using mobile sensing data to personalize treatments for depression and to study a treatment\u2019s effectiveness. Andrew remains passionate about reducing the stigma of mental illness so more patients in need seek effective evidence-based treatments.<\/p><\/div><\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n

Rachel graduated from the University of Washington, Seattle, with a dual degree in Psychology and the Comparative History of Ideas in 2017. While at UW, she worked as a research assistant in Dr. Katie McLaughlin\u2019s Stress and Development Lab and in the Department of Psychiatry\u2019s Division of Public Behavioral Health and Justice Policy. After graduating, Rachel spent a year serving as an AmeriCorps Volunteer in Nashville, TN, where she worked as a college access counselor. Rachel then joined the Stanford SNAP Lab as a research coordinator, where she managed a longitudinal study examining the effects of early life stress on neurobiological, behavioral, and cognitive development across adolescence.

Rachel joined the Mood Disorders Laboratory in 2021. She is interested in the role cognitive biases play in the development and maintenance of depression, and how these biases impact the way people think about themselves and their interpersonal relationships. Rachel is also interested in psychopathology classification and utilizing dimensional and symptom-level approaches to studying depression in her research.<\/p><\/div><\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n
