Current Roles
I am an Associate Professor at Texas Tech University, Chief Science Officer at Vineyard, and Owner of Tinsley Consulting LLC.
At Texas Tech University, I perform academic research, mentor student researchers, and teach undergraduate and graduate courses. I lead a team of researchers as the Director of the Energy Balance & Body Composition Laboratory. The major interests of my laboratory are the critical evaluation of body composition assessment techniques, energy balance manipulations ranging from intermittent fasting to overfeeding, and sports nutrition strategies to improve performance and body composition.
At Vineyard, a virtual health clinic specializing in GLP-1 medicines and cardiometabolic health, I provide scientific guidance and facilitate research projects to examine the influence of obesity medications on body composition, muscular performance, nutrition intake, and other health markers.
I serve as a science advisor for several companies in the fitness, health, and nutrition space, including Legion Athletics and Prism Labs.
Through Tinsley Consulting LLC, I provide consulting services in the areas of scientific review, data analysis, and sports nutrition.
Academic Achievements
At Texas Tech University, I have directed 14 externally funded research studies, along with 8 additional contracts for research services. These research activities, along with external collaborations, have resulted in over 240 published peer-reviewed articles and abstracts. My work has been published in top research journals, such as The American Journal of Clinical Nutrition, Nutrition Reviews, and Medicine & Science in Sports & Exercise.
I received the 2018 Best Paper Award from the European Journal of Sport Science for my team’s investigation of the effects of intermittent fasting on adaptations to resistance training. I also received the 2019 New Faculty Award from the Texas Tech Alumni Association and the 2021 Excellence in Research Award from the College of Arts & Sciences at Texas Tech University. I was the 2021 recipient of the Nutritional Research Achievement Award from the National Strength and Conditioning Association.

I have been interviewed on numerous podcasts and lay articles. My research has been featured or discussed in a variety of additional articles, podcasts, and other media.
Background
I was homeschooled throughout my childhood and began taking college courses at age 15. I attended Oklahoma State University on a full-ride National Merit Scholarship and graduated summa cum laude with dual degrees in Physiology and Nutritional Sciences. I then completed a master’s degree in Biomedical Sciences at Colorado State University and a Ph.D. in Kinesiology and Exercise Nutrition at Baylor University. I began a tenure-track Assistant Professor position at Texas Tech University at age 25 and was tenured and promoted to Associate Professor, my current position, at age 30.
In addition to my traditional academic degrees, I have completed a Graduate Certificate in Medical Statistics from Stanford University and additional data analysis education through DataCamp. I am a Certified Strength and Conditioning Specialist with distinction (CSCS,*D) and a Certified Sports Nutritionist (CISSN).
Personal
I live in Lubbock, Texas. I enjoy spending time with my family, lifting weights, reading, playing games, and being active in my local church community.
I actively explore how my Christian faith influences the way I approach all areas of life, including my work, physical fitness, finances, and decision making in general. Much of my recreational reading involves these topics, and I curate lists of resources I find helpful for these areas, which can be accessed under “Resources” in the site menu.
