Long Bio

I am currently an Associate Professor in the College of Health Solutions at Arizona State University, Phoenix, Arizona. My academic career spans across the US, UK and Australia, and I have published and presented in numerous international forums on topics such as buffering supplementation and maximizing human performance, hydration in athletics and team sports, athlete monitoring in team sports, and injury prevention. Currently, my research interests are primarily focused around fatigue reduction in the context of human exercise performance.
