Grace G. Wyshak is an American biostatistician known for her work on twins and heritability of genetic information and in defining the factors impacting girls as they develop into young women.
[8] Wyshak's epidemiological research helped clarify observed relationships between physical activity (exercise) and reduced breast cancer and depression risks.
[11] She also investigated people's willingness to engage in risky behavior, a topic she examined based on a comparison between doctors and lawyers.
[12] Wyshak and Rose Frisch's collaborative work determined that exercise reduced risk of certain cancers,[13] and that drinking carbonated beverages increased the likelihood of bone fractures in young girls.
[14][15] Wyshak went on to investigate the link between soda consumption by adolescent girls and bone fractures,[16] research that was broadly covered by the media.
