Mario Kratz, PhD

Founder

Headshot round

Welcome! My name is Mario Kratz, and I am the founder of Nourished by Science. Allow me to introduce myself as well as my scientific qualifications and background.

I have Master’s and PhD degrees in Nutrition Sciences from the University of Bonn in Germany. Currently, my primary job is as a faculty member at the Fred Hutchinson Cancer Research Center in Seattle, WA, where I am an Associate Professor in the Cancer Prevention Program, part of the Public Health Sciences Division. I am also a faculty member in the Departments of Epidemiology and Medicine as well as the Nutritional Sciences Program at the University of Washington, also in Seattle, WA. 

My laboratory conducts clinical research in the area of diet, obesity, and chronic diseases, with a major focus on metabolic diseases such as type 2 diabetes, cardiovascular disease, non-alcoholic fatty liver disease, and cancer. We are particularly interested in the mechanisms through which diet affects energy homeostasis (i.e., how the body regulates weight and fat mass) and processes that contribute to chronic disease, such as low-grade chronic inflammation or insulin resistance. You can find some more information about our work on my lab web site, and my scientific publications on my Google Scholar profile.

As a core faculty member of the Nutrition Sciences Program at the University of Washington, I regularly mentor students in our Master’s and PhD programs. I also used to teach a course in Nutritional Epidemiology (NUTR 538 / EPI 538) for many years. This course focused heavily on the methods used in observational studies and randomized controlled trials. I also serve on the editorial board of the American Journal of Clinical Nutrition (AJCN), and used to serve on the editorial board of the Journal of Clinical Endocrinology and Metabolism (JCEM) between 2016 and 2019.

Please note that this website is not related to my employment at Fred Hutchinson Cancer Research Center or my academic appointments at the University of Washington. All posts are based on my own independent work, and not related in any way to Fred Hutchinson Cancer Research Center or the University of Washington.

On a personal note, I live in Seattle, WA, with my wife Rebecca and our two children, Luca and Sam. In addition to the science of nutrition, I do enjoy the practical applications of nutrition, i.e., gardening, cooking, and eating. I love hiking through the beautiful Pacific Northwest mountains, yoga, playing squash, the game of Go (and board games in general), and anything that involves my family.
