Keely Muscatell, PHD

Keely Muscatell is an assistant professor in the Department of Psychology & Neuroscience and the Lineberger Comprehensive Cancer Center at UNC Chapel Hill. Trained as a social neuroscientist, her research focuses on elucidating the neurobiological mechanisms that link social experiences and health. Her work is highly interdisciplinary, as she employs theory and methods from social psychology, cognitive and affective neuroscience, psychoneuroimmunology, pharmacology, and population health. Keely completed post-doctoral training in the Robert Wood Johnson Foundation Health and Society Scholars program at UCSF/UC Berkeley, and in the Psychology Department at Berkeley. She received her Ph.D. in Psychology from UCLA in June 2013, an MA in Psychology from UCLA in 2009, and a BA in Psychology and Spanish from the University of Oregon in 2006. When not in the lab, Keely can be found reading Dave Eggers, Ben Lerner, and Zadie Smith, watching college football, and/or drinking craft beer while listening to their vinyl collection with her partner, Dave Rose.



Monica M. Gaudier-Diaz, PHD

Monica is a postdoctoral fellow in the lab. She completed a BS in Biology at the University of Puerto Rico in 2008 and a PhD in Neuroscience at The Ohio State University. Interested in how environmental factors influence health, Monica decided to join to the Social Neuroscience & Health Laboratory where she is expanding her training in this area. In her free time, she enjoys spending time with her family and friends, listening to music, going to the beach, visiting the zoo, and trying new restaurants/ bars.




Jenn is a sixth-year doctoral student in Social Psychology at UNC. She researches how bodily changes (e.g., interoceptive awareness, hunger, inflammation, physiological aging) can shift our emotions, social perceptions, and affect-based decisions. To test these connections, she draws on social cognition, peripheral psychophysiology, psychoneuroimmunology, and social affective neuroscience. Jenn's research is supported by an NRSA Predoctoral Fellowship from the National Institute on Aging, as part of her dissertation. She hopes to become a tenure-track professor at a research university and build a lab that uses social affective, developmental, and interoceptive science to explore the mind-body link. In 2013, she received her B.A. in Psychology from NC State University. Before that, she studied Welsh language and literature at Bangor University in North Wales, UK for four years. In her free time, Jenn enjoys writing fiction, hiking through the Carolina Piedmont, and playing video games.

Becky Salomon, MSN

Becky is a fourth-year doctoral candidate in the School of Nursing at UNC. Her research focuses on a specific subset of depressive symptoms (depressed mood, chronic pain, cognitive dysfunction, sleep disturbance, and fatigue) which is called the psychoneurological symptom cluster in Nursing science. For her dissertation, which is supported by an NRSA Predoctoral Fellowship from the National Institute on Nursing Research, Becky is looking at whether the symptoms are associated with the chronic situational stress experienced by low-income mothers as well as whether the symptoms are associated with maternal function and their child’s behavior. She hopes to follow up this research with an exploration of chronic stress, inflammation, and the development of symptoms. Her long-term research goal is to develop an accessible stress intervention for the dually vulnerable population of mothers and children. Becky received a B.A. in Psychology and English at Wellesley College in 2008. After spending time working with children in a variety of settings, including on a biodynamic dairy farm in upstate New York and at an overnight camp in Western North Carolina, she attended Vanderbilt University and received her MSN in Psychiatric Mental Health Nursing across the lifespan. When she’s not wearing her academia hat, she loves to garden, cook, and spend time with her wife and their daughter.


Gabriella M. Alvarez, AB 

Gaby is a second-year dual clinical and social doctoral student in the Department of Psychology & Neuroscience at UNC.  Supported by an NSF GRFP as well as a Pre-doctoral Ford Foundation Fellowship, she is gaining skills in psychoneuroimmunology and affective neuroscience to study how social contexts affect psychobiological responses to stress. Ultimately, her work aims to improve our understanding of how the social world sculpts biology, and will reveal the mechanisms underlying socioeconomic and racial health disparities. Gaby aspires to become a tenure-track faculty at a research university where her study of the social determinants of health not only contributes to advances in biology but also influences health policy and equity. In 2015, she received her A.B. in Psychology and Anthropology at Washington University in St. Louis. Following graduation, she completed a post-baccalaureate intramural research training position at the National Institute of Mental Health. In her spare time, Gaby enjoys eating, listening to podcasts, and bonding with her kitten Lillith.

Tatum A. Jolink, BA

Tatum is a second-year doctoral student in Social Psychology at UNC. She researches the role of socioeconomic status in close relationship functioning and well-being. Tatum hopes to integrate the often-overlooked context of SES into relationships science to better understand the basic mechanisms at the root of high-quality relationships. Specifically, she researches how SES impacts the provision of high-quality social support within close relationships, during both everyday life and times of stress. As a part of the SNH lab, she aims to ultimately examine how close relationships and SES work together to influence health. Tatum hopes to become a tenure-track faculty at a research university studying the dynamics of close relationships, socioeconomic context and health. In 2015, she received a BA in Psychology, History and Plan II Honors from the University of Texas at Austin. She then took a post-bac at Yale University working with Dr. Margaret Clark in her Relationship Science Lab before starting graduate school at UNC. If she’s not doing research, Tatum can be found running or hiking outside, beer tasting or cooking new recipes with her partner.

Carrington is a first-year doctoral student dually enrolled in Clinical and Social Psychology at UNC. Prior to being a graduate student, she worked as an undergraduate research assistant in the Carolina SNH lab while obtaining a BA in Psychology at UNC. Carrington's primary research interests are in how social conditions influence neural, physiological, and psychological functioning, and thus contribute to the onset, course, and treatment of severe mental illness, specifically schizophrenia. In her graduate studies, she plans to investigate social determinants of schizophrenia pathology, their associations with neurobiological mechanisms underlying schizophrenia risk, and how these associations may vary across socially advantaged and disadvantaged groups. To explore these interests, she hopes to use a mixed-method approach incorporating psychophysiology, neuroimaging, and behavioral experiments. It is her desire to use this research to help inform the development of more socially- and culturally-conscious interventions for those suffering from psychosis-related illnesses. In her spare time, Carrington enjoys running, reading historical fiction novels, and watching stand-up comedy specials on Netflix. 

Laboratory Manager


Samantha N. Brosso, BS

Samantha is the SNH laboratory manager. Before her post-bac position, she graduated with a B.S. in Psychology from UNC Chapel Hill. She hopes to pursue a PhD in Social Psychology, with a specific focus on physical and emotional health. As a future graduate student, she would like to explore the physiological and neural mechanisms that set individuals on unique life-history trajectories. More specifically, she would like to disentangle how people’s early life experiences and current social world (i.e. social status, socio-cultural environment, social interactions) impact their brain and stress response system, and in turn, how the organization and function of these biological systems influence the way in which individuals interact with the world around them. In her spare time, Samantha enjoys playing her guitar, writing songs, and playing with her two guinea pigs.
