Principle Investigator

Kathleen Keller

Kathleen Keller

Kathleen received her B.S. in biology from Marquette University in 1995 and her Ph.D. in nutritional sciences from Rutgers University in 2002. She completed a post-doc in pediatric obesity at the New York Obesity Nutrition Research Center and was an Assistant Professor of Clinical Nutrition at Columbia University, College of Physicians and Surgeons before coming to Penn State in 2012 to join the Departments of Nutritional Sciences and Food Science. She is the Director of the Metabolic Kitchen and Children’s Eating Behavior Laboratory at Penn State. Current studies in the laboratory involve understanding the effects of genes on children’s fat preferences and identifying neural pathways involved with overeating and obesity. In addition, she and her team are currently conducting home-based interventions to help children consume more vegetables. She hopes that one day this research will help develop new treatments for childhood obesity. Kathleen also enjoys teaching, reading, cooking, and watching movies with her husband.

Postdoctoral Fellow

Alaina Pearce

Alaina PearceAlaina Pearce received her B.A. in Psychology and Spanish with a minor in statistics in 2011 from the University of Minnesota Morris and her PhD in Psychology with an emphasis on Lifespan Cognitive Neuroscience from Georgetown University in 2017. She is currently a post-doc in the lab. Her primary research interests center on understanding the reciprocal relationship between neurocognitive function and pediatric obesity by examining 1) feed-forward neurocognitive processes that confer risk or resiliency for obesogenic behaviors and pediatric obesity, and 2) feed-back effects of deleterious comorbidities of pediatric obesity on neurocognitive functioning. Her current projects examine the determinants of loss of control eating in children, the role of BMI and sex in the development of appetitive traits across childhood, and the role of familial obesity risk on neural processing of food cues.

Graduate Students

Nicole Reigh

Nicole Reigh

Nicole Reigh received her B.S. in Nutritional Sciences from Penn State in 2017, and is now a PhD Candidate working on a dual-title degree in Nutritional Sciences and Clinical & Translational Sciences. Her main research interest is understanding the development and improvement of children’s self-regulation of food intake. She is currently leading the Hunger and Fullness Study, a project that aims to teach children how to better identify and respond to internal cues of huger and fullness. Upon graduation, Nicole hopes to complete post-doctoral training before pursuing a career in the translation of research into policy and guidelines.

Bari Fuches

Bari FuchsBari Fuchs received her B.S in Neuroscience and Behavioral Biology from Emory University in 2015 and is now a Ph.D. Candidate in Nutritional Sciences. Prior to joining the lab, she was a research assistant at the National Institute of Mental Health studying the effect of anxiety on reward processing and working memory. Her research interests involve understanding the cognitive and decision-making processes that contribute to maladaptive eating behaviors, such as disinhibited eating. Outside the lab, you can find Bari hiking, weightlifting, and frequenting coffee shops and farmers markets.
