Daisy grew up in Brooklyn, NY and graduated from Stanford University in 2019 with a B.A. in Psychology and a B.A in East Asian Studies (Japan). During her time at Stanford she worked as research assistant in the SNAP (Stanford Neurodevelopment, Affect, and Psychopathology) lab and spent over 5 months studying abroad in Japan. In her senior year she wrote a capstone paper called Convenience Store Woman: The In’s and Out’s of Normality where she aimed synthesize her academic backgrounds to analyze the Japanese novel Convenience Store Woman by Sayaka Murata; she was also able to present her work at Stanford’s inaugural Disability Studies conference. In the SNAP lab, Daisy is a full-time research coordinator for the March of Dimes project. Daisy is interested in developmental psychopathology, mental health, emotion regulation, and how personal and group identities impact the aforementioned categories in children through adolescents. In the future, she hopes to pursue a Ph.D in Child Clinical Psychology. Outside the lab, you can find her gardening, reading, doing arts and crafts, cooking, or spending time with family and friends. 

Mahmoud Farghal

Mahmoud grew up in Ann Arbor, Michigan and graduated from the University of Michigan in 2019 with a BS in Biopsychology, Cognition, and Neuroscience. At Michigan, Mahmoud worked in labs across several disciplines such as social psychology, cardiology, and pulmonology. Broadly, Mahmoud’s research interests include understanding how various environmental and genetic factors in childhood are associated with anxiety disorders, and getting a better grasp of the neurobiological mechanisms of anxiety disorders in the brain in order to improve treatment. He is a full time behavioral coordinator working on the Early Life Stress project. Outside of the lab, you can find him playing soccer, spending time with friends and family, and watching Bachelor in Paradise.

Justin Yuan

Justin is a first-year graduate student in the SNAP Lab. He is broadly interested in developing robust markers of normative and atypical adolescent brain development. His research focuses on how factors such as early life stress and current psychopathology influence the developmental trajectories of structural and functional brain networks. Prior to Stanford, Justin worked on MRI studies investigating white matter network changes in adolescent brain cancer survivors, biological mechanisms of meditation practice in teens, and the reliability of graph theoretical methods.

Rajpreet Chahal

Raj received her Ph.D. in Human Development and Designated Emphasis in Translational Research from the University of California, Davis in 2019. Raj was a TL1 Pre-Doctoral Clinical Research Training Scholar and supported by the UC Davis School of Medicine and the NIH National Center for Advancing Translational Sciences. In her graduate work, Raj assessed how inter-individual differences in key developmental aspects of adolescence (i.e., puberty, psychopathology, and the brain) inform one another to contribute to our understanding of heterogeneous risk mechanisms and opportunities for targeted interventions. Specifically, Raj characterized associations between pubertal timing, structural and functional network properties in the brain, and internalizing symptoms. Raj also examined how topographical signatures in white matter tracts reflect the history of depressive symptoms in adolescent girls, and how patterns of functional connectivity, revealed by neural biotyping, forecast future internalizing symptoms in at-risk adolescents. As a post-doctoral researcher in the SNAP lab, Raj is extending her work by studying the effects of early life stress on the development of large-scale structural and functional brain circuits to understand when and in whom neurobiological alterations arise and confer risk for depression and suicidal ideation. The goal of this research is to guide person-centered approaches to detect vulnerability for, and predict the course of depression.

Giana Teresi

Giana grew up in Irvine, California and graduated from the University of California, Berkeley with a B.A. in Psychology in 2019. During her undergraduate career, Giana worked as a research assistant in Dr. Harvey’s Golden Beer Sleep and Mood Research Clinic where she worked on two non-medication treatment studies for depression and teen sleep, respectively. She also worked as a research assistant in Dr. Keltner’s Social Interaction Lab where she wrote her honors thesis on cross-cultural differences in the emotion of awe. After graduating, Giana became a full-time research coordinator for the Stanford Teen Mood Study. Giana’s research interests broadly include the interaction of social and biological risk factors in the development of psychopathology in adolescents as well as mechanisms of resilience. Outside the lab, Giana enjoys writing music, re-reading Harry Potter, and trying out new restaurants.

Jillian Segarra

Jill grew up on Long Island, NY, and graduated from Columbia University in 2018 with a B.A. in Neuroscience and Behavior. During her time at Columbia, Jill worked as a research assistant in Dr. Larisa Heiphetz’s Social and Moral Cognition Lab, and as a lab manager in Dr. Darcy Kelley’s lab on auditory perception and vocalization. In the Gotlib lab, Jill is the project coordinator for the March of Dimes Preschool Follow-Up. She also contributes to the lab’s neuroimaging work, running MRI and fNIRS scans with various populations. Broadly, Jill’s research interests include neurological and psychiatric disorders, developmental psychobiology, and psychopharmacology. In the years to come, Jill plans to continue her studies by pursuing a Ph.D. in Neuroscience. When Jill’s not in the lab, you can find her baking cookies, making art, and finding any excuse to be outside.

Lauren Borchers

Lauren is a graduate student in the Stanford Neurodevelopment, Affect and Psychopathology lab. Broadly, Lauren is interested in the intergenerational transmission of psychopathology and the neural correlates of depression. Her research assesses how varying levels of maternal depression and anxiety impact infant white matter microstructure at birth and the role of the cerebellum in relation to depressive symptomatology in adolescents. Prior to joining the lab, Lauren investigated the neural bases of reading and language development in children born preterm using diffusion and quantitative MRI.

Fran Querdasi

Fran grew up in Seattle, WA and graduated from Pomona College in May of 2018 with a BA in Psychology. At Pomona, Fran worked as a research assistant in the CARE (Childhood Attachment, Relationships, and Emotions) lab and as a volunteer mental health counselor at a local high school. In the SNAP lab, Fran is the project coordinator for the BABIES project, and also works on the March of Dimes and Early Life Stress projects. Fran is interested in how childhood adversity and the early environment affect development, mental health, and resilience. In the future, Fran hopes to pursue a Ph.D. program in developmental clinical psychology. Outside of work in the lab, Fran enjoys running, hiking, cooking, and spending time with family/friends.

Past Projects

Information-Processing Biases in Depression and Anxiety
Children and adults diagnosed with clinical depression or anxiety have been found to exhibit biases in their processing of emotional information, particularly when they are in the midst of a significant episode of the disorder. The causal status and functional significance of these biases in precipitating and maintaining depression and anxiety is not yet clear. One major aim of our research is to examine the role of these maladaptive forms of information processing, assessed both in the laboratory and in day-to-day experience, in the onset and maintenance of episodes of depression and anxiety, and in recovery from these disorders.

fMRI and the Neural Bases of Depression and Anxiety
A growing body of research is demonstrating that depressed and anxious people differ from their non-disordered peers both in the volume of specific brain structures and in their patterns of neural activation as they process emotional stimuli. We are using functional magnetic resonance imaging (fMRI) to examine patterns of brain activation that characterize the functioning of depressed and anxious individuals as they process emotional information and respond to various types of positive and negative stimuli, and at rest in the scanner.
