Research Team

Our research group, led by Robert Levenson, Ph.D, seeks to understand the nature of human emotion in terms of its physiological manifestations, variations associated with age, gender, culture and clinical pathology, and the role emotion plays in interpersonal interactions.


ROBERT W. LEVENSON
DIRECTOR & PRINCIPAL INVESTIGATOR

Robert W. Levenson works in the areas of human psychophysiology and affective neuroscience, both of which involve studying the interplay between psychological and physiological processes. Much of his work focuses on the nature of human emotion, in terms of its physiological manifestations, variations in emotion associated with age, gender, culture, and pathology, and the role emotion plays in interpersonal interactions. Dr. Levenson's research group is currently focusing primarily on two major projects: a study of emotion and normal aging and a study of the impact of neurodegenerative diseases on emotional functioning, both supported by grants from the National Institute of Aging.

Kuan-Hua Chen
POST DOCTORAL RESEARCH FELLOW

Kuan-Hua Chen’s research aims to understand how emotional functioning changes in healthy aging and age-related neurodegenerative diseases including dementia and Parkinson’s disease, the neurobiological underpinnings of these changes, and the pathway via which emotional impairments in one person undermine the health and well-being of their loved ones such as spousal caregivers. He received a PhD in Neuroscience from the University of Iowa in 2015. He is a recipient of an NIA Pathway to Independence Award (K99/R00). He is originally from Taipei, Taiwan.

Her current research examines the relationship between connectedness and well-being in spousal caregivers of dementia patients, as well as factors that protect against loss of connectedness in patient-caregiver dyads over time (i.e., disease type, patient functioning, caregiver characteristics).

Ana Fonseca
POST DOCTORAL ALUMNI

Ana Fonseca is a post-doctoral alumni in the Berkeley Psychophysiology Laboratory. Ana does research on health, emotions, regulation, and close relationships. Through intrapersonal and interpersonal statistical techniques, she is interested in advancing research on how partners continuously exchange, influence, and respond to one another’s emotions over time during the presence of an illness and in times of wellness for one or both partners. These intertwined mechanisms thus, lead to changes to health (mental, behavioral, and physical) that are significantly important to the general public but also for developing effective and targeted interventions that focus on family systems (e.g., caregiver/patient) rather than just the individual. Research in this domain is important for understanding how people can reduce the onset of an illness but also inform what individuals can do in their daily lives to increase healthy quality lifestyles and relationships as they age.
