GRADUATE STUDENTS
Mahnoor Hyat (she/her) | Graduate StudentMahnoor is a fourth-year graduate student in the GRaND lab. She earned her BA with honors in Psychology from Stanford University in 2022. She is dedicated to investigating heterogeneity in the development and expression of mental illnesses. Her research focuses on identifying early neurobiological and sociocultural indicators, which could help inform preventative measures for at-risk individuals. At Stanford, she worked in the Stanford Neurodevelopment, Affect & Psychopathology Lab under Dr. Ian Gotlib on projects related to maternal mental health, child neurobehavioral development and prenatal health. Her honors thesis used network analysis to examine behavioral and emotional symptoms in black children from low-income, unmarried-parent households. Her current work is focused on delineating the genetic, neural and behavioral mechanisms of serious mental illness such as schizophrenia in diverse populations across contexts. She recently led a project that looked to parse out genetically mediated cognitive, behavioral, emotional and social precursors of schizophrenia in childhood and early adolescence and is now working on examining the neural and mechanistic underpinnings of these associations. In her free time, Mahnoor enjoys going on boba walks, watching movies and spending time with friends and family!
