Perhaps more so than ever before, the world desperately needs critical thinkers, creative problem solvers, and curious scientists. This is true in every aspect of our culture and in every sector of society. Whether it is in academia, government, business, media, or non-profit; critical, evidence based reasoning and creative problem solving is clearly an asset to every organization and to the world. As a science teacher, my responsibility is to encourage every student’s innate curiosity, ignite their imagination, and inspire the continuous pursuit of knowledge. Higher level knowledge occurs when students can begin to apply the concepts, analyze, and evaluate why certain phenomena occur or exist; ultimately using their knowledge to explore and create novel ideas and insights. This is my purpose as a science teacher: to provide the platform for students to explore big scientific questions, to be independent critical thinkers, and to become creative problem solvers.

Dr. Wilkins has a diverse scientific background within both industry and academic research settings. His current research focus explores factors that can alter the balance of oxygen supply and demand during exercise and their impact on muscle bioenergetics, oxygen uptake kinetics, fatigue, and human performance. Previous research topics include blood pressure regulation, control of muscle blood flow during exercise, thermoregulation, and physiological models predicting athlete performance. There are a variety (numerous) student research ideas utilizing tools like near infrared spectroscopy (NIRS), beat by beat blood pressure, oxygen uptake, blood lactate analysis, and EMG (to name a few) to explore questions around how altered mechanics contribute to muscle fatigue, changing muscle activation patterns with limited muscle oxygen supply, how disrupting the balance of oxygen supply and demand alters bioenergetics, and many others. Dr. Wilkins has a keen interest in how all these interrelationships can impact human performance.
