I received my B.S. in Nutritional Sciences from Cornell University in 1991 and completed a dietetic internship at Emory University in Atlanta, GA in 1992. I then started my clinical career practicing as a registered dietitian focusing on the nutritional care of oncology, general medicine, and geriatric patients. I furthered my clinical training at the Geisel School of Medicine at Dartmouth, graduating in 2001 with an M.D. degree.
My research career started in the area of AMP-activated-kinase in skeletal muscle in the Department of Medicine at Dartmouth investigating the impact of alterations in AMPK activity on glycogen metabolism and exercise capacity. Although working at the cellular and murine model level intrigued me, I felt too removed from the patient population and moved to human based research. Maintaining a strong interest in geriatrics, I conducted research in the area of health care decision-making in the oldest-old at The Dartmouth Institute for Health Care Policy and Clinical Practice. Through this qualitative research, I observed that older adults desire maintenance of quality of life over quantity of life. I then completed an NIH T32 Post-doctoral Fellowship within the Geisel School of Medicine focusing my work in two areas (1) sarcopenia and obesity in older adults and the impact on functional status and (2) healthy eating in those with obesity and serious mental illness. In 2013 I received a young investigator award from the Obesity Society for my work in the area of obesity and nutritional status in those with serious mental illness.
At Cornell, I have continued my research in the area of geriatrics/older adults, expanded my work in the area of altered eating behaviors, and initiated novel research in the area of social media and nutrition. Through community based participatory research I am investigating the implementation and impact of the aging in place program, Full Circle America Steuben, to improve successful aging in Steuben County, NY. Considering the contribution of obesity and sarcopenia to reduced functioning in older adults, I investigate interventions that improve health behaviors in young and middle aged adults with the aim of preventing later life medical and functional disability. This work includes study of the Body Positive Cornell program, a peer delivered program to improve body appreciation and reduce disordered eating and the Weigh2Go study for promotion of weight maintenance in early-mid adulthood. Social media provides a means for communicating about nutrition and eating behaviors to a broad audience of all ages. In this area, my lab focuses on describing food and eating related posts on social media and exploring their association with dietary intake and eating behaviors.
The overarching goal of my research program is to reduce obesity and sarcopenic obesity in late life adults. Using a biopsychosocial model for obesity, I aim to identify biological, psychological and social modifiable risk factors across the lifespan for obesity and sarcopenia in later life and develop interventions that target these factors. Recognizing disordered eating as a psychological risk factor for obesity in later life, I am studying Body Positive Cornell, a peer led program that promotes body acceptance to reduce and prevent disordered eating in young and middle aged adults. To address the modifiable biological risk factors of age related weight gain and weight cycling, I am investigating the effectiveness of daily weighing to promote weight maintenance in middle aged adults. Using netnographic methodology, I am investigating food related communications on social media and their potential impact on eating behaviors. In late life adults, I am conducting an effectiveness-implementation study using community based participatory research to investigate Full Circle America Steuben, a multi-modal aging in place program for at risk late life adults living in Steuben County, NY.

I teach within the Post Baccalaureate Program, preparing students for future careers in the health sciences. Today’s clinicians confront an overwhelming barrage of information with research results, expert opinions, and clinical guidelines being published and updated regularly online. New information needs to be efficiently deciphered, sorted, and integrated with existing knowledge to allow for application. This process requires strong core knowledge and the ability to think critically about new and existing information. My goal is to teach students critical thinking and to inspire a love of learning, so that they can welcome this daily deluge of information and become lifelong learners.
Each student brings a unique combination of prior knowledge, perspective and cultural context to the classroom. To address these individual differences and use them to enhance learning for all students, I use a variety of teaching methods. My classes are combinations of short didactic sessions, class activities and small group learning. I use a “flipped classroom” model with core knowledge being learned outside of the classroom and application of the information practiced in the classroom through case studies, problem based learning, and laboratory exercises. I emphasize a collaborative and team based approach to learning. No one person can know everything and thus students need to learn how to effectively and efficiently communicate and work with one another to solve clinical problems.
In terms of mentoring, I emphasize self-reflection and goal setting. I encourage the post baccalaureate students to reflect on the areas of study they are passionate about or find intellectually interesting and to self-identify strengths and weaknesses to aid in planning current courses of study and future career directions. For my research mentees, I encourage independent work with regular meetings to discuss progress on study design, IRB materials, study implementation, data management and analysis, and writing. I also strive to mentor my graduate TA’s in teaching by including them in most aspects of course planning and delivery.
