Research and Teaching Interests:

Nearly a third of us will suffer from a mental illness during the course of our life, and many will experience comorbid physical health problems (e.g., gastrointestinal disorders). Early life experiences are known to shape both physical and mental health, however, the precise mechanisms by which such shaping occurs have yet to be established. My program of research examines how different early life experiences influence interactions between physical and mental health across the lifespan. In the Brain and Body Lab (BaBLab) we undertake such analyses at the level of behavior, neural systems (using fMRI), gastrointestinal bacteria and health (i.e., the microbiome), and physiology (e.g., gastric function, heart rate, skin conductance). It is our goal to use this research to create better mental and physical health treatments across development, informed by psychological functioning, trauma history, and central and peripheral biology.
