Areas of Expertise: Strength and Conditioning, Muscle Physiology, Endurance Athlete Performance, Tactical Athlete Energy Expenditure and  Job Task Economy, Research, Sports Performance and Nutrition, Bioenergetics

What is the most important piece of advice you give students to help them succeed?
It's okay, and encouraged, to challenge common thoughts and beliefs in the field of exercise physiology. A lot of unknown still exists within the scope of athlete performance as well as chronic disease populations. Exercise Science is a broad field in which, as a professional, you will always be helping someone. Continue to serve and help others, challenge common ideas, and stay up-to-date in the field!

Is there any additional personal experience you would like to share?
I am always doing something active. I love to swim, bike, run, and lift. I'm a multiple IRONMAN finisher, and love to train within the sport of triathlon. I have coached many athletes to world championship qualifications, ultra-endurance race finishes, marathon swims, and more. I love using my knowledge within the field of Exercise Physiology to help others, and improve athletic performance.
