0:00.0	Hello and welcome to this special collaborative podcast episode again with Sigma Nutrition, Iron Culture, and the Sports Nutrition Association. My name is Danny Lennon. Joining me as co-host is Dr. Eric Trexler. Eric, how are you today? I'm doing great, and I've actually demoted myself. I am the assistant host. Oh, not the co-host, but I appreciate that.
0:24.1	Well, it's great to have you here in whatever capacity, but even more exciting and more of an
0:29.9	honor than that is the guest that we have talking with us today, Dr. Sean Arendt, who has done
0:36.2	extensive work in a range of topics, some of which we're going
0:39.3	to discuss today. And I know a number of our listeners will probably be already familiar with

1:33.7	USC is one of the top, has one of the top PhD programs in the country by the National Academy rankings, and we have for almost 20 years now. We're at the top for about 15 of those.
1:39.6	We're sitting in the top two or three at the moment, and one of the top sports science universities
1:43.4	in the world as well,
1:44.4	and number three in the U.S.
1:45.8	So we're really proud of the work we do here.
1:48.1	We work very closely with athletics.
1:50.8	Much of my work revolve, really, I deal in applied physiology, right?
