 Safety and efficacy are important is how we translate things from animal studies and from Petri dish studies to caring for our patients and improving the lives of our patients. This whole family, so to speak, is important and rubbing up against the people I rubbed up against in fellowship and then that we see at the meetings on a regular basis is important. Having a collaborative scientific event is very important too because for these translational steps you have to have big populations of people and so we're all going to have to work together in order to answer a lot of these questions. We need collaboration between sites. We need large numbers of in the hundreds to two hundreds to three hundreds to answer some of these questions and the key to getting that data to getting that information is collaboration between sites and so it's always fun to to see my mentors again to still learn from them but then also to strike up ways to collaborate too.
