Postdoctoral Scholars

Jessica Irwin, Ph.D.

Dr. Irwin is interested in the dynamic, transactional processes among biological, psychological, and social systems in pregnancy through early childhood. More specifically, how these factors may alter trajectories of child cognitive, socioemotional, and neurobehavioral development, particularly in families from diverse racial/ethnic and socioeconomic backgrounds, and children with and without autism or developmental disabilities. She is also interested in disability advocacy and research that has the potential to influence public health and disability policy. 

Mentor: Chris Dunkel Schetter


Jeff Hunger, Ph.D. 

Dr. Hunger’s research uses insights from psychology to understand and improve the health of stigmatized populations (e.g., higher body weight individuals, racial/ethnic minorities). His research examines the consequences of possessing a stigmatized identity through the lens of social identity threat, and uses both experimental and non-experimental methods. He approaches health at multiple levels of analysis, including outcomes such as physiological indicators of stress (e.g., cortisol, cardiovascular reactivity), health behaviors (e.g., disordered eating), and mental health (e.g., depression).

Jacqueline H.J. Kim, Ph.D.

Dr. Kim is interested in uncovering variations in coping for persons experiencing internalizing symptoms and somatic symptoms amid chronic adversity, as in cancer. During fellowship, she seeks to better understand patients experiencing pain, fatigue, and depression—a constellation of symptoms related to a poorer quality of life in cancer survivorship. Dr. Kim is also interested in how personal history (e.g., childhood adversity) and culture (e.g., Asian values) influence psychological distress, somatic symptoms, coping, and well-being. Dr. Kim intends to apply findings from her research to develop culturally-relevant and broadly disseminable interventions to improve mental and physical health.

Mentors: Annette Stanton, Anna Lau

Nicole Mahrer, Ph.D. 

Dr. Mahrer’s research focuses on understanding the effects of parenting and family environment on child physical and mental health outcomes. She investigates the interplay between physiological and psychological health as well as cultural differences in pathways predicting positive and negative outcomes. Dr. Mahrer also conducts research within the field of pediatric psychology, specifically studying how to better integrate mental health intervention into pediatric hospital settings using a culturally-informed and sensitive approach.
