Dr. Tomiyama’s research focuses on eating behavior, psychological stress, and cellular aging with focus on macro factors like socioeconomic status to micro factors like telomere shortening (a biomarker of age.)

Dr.Tomiyama’s expertise also lies in dieting and the potential negative psychological and biological consequences. Her research tests questions such as: Is “comfort food” really comforting? Is dieting stressful? Does stress age our immune system and, if so, how? Can calorie restriction reverse this type of aging? Who are our society’s most successful dieters, and what can we learn from them? Is stress to blame for racial disparities in obesity? What are the negative health consequences of experiencing weight stigma? 

Dr. Tomiyama has been featured in publications such as USA Today, the Chicago Tribune and BBC News, where she discussed stress hormones and their effects on dietingstress eating and African American girls and the relationship between dieting and longevity.
