He is also a scientist and emeritus professor at UCLA, Center for Health Sciences. He has published over 200 peer-reviewed scientific papers, in addition to chapters and books on topics as wide-ranging as biostatistics, translational healthcare and molecular immunology. He is a Fellow of the American Association for the Advancement of Science, one of the few overseas Fellows of the Royal Society of Medicine and a Fulbright alumnus.He values science as the pursuit of our abilities to think and to reason, but believes that this ability is always secondary to our grace of faith: a person can be a good and sound scientist while remaining true and committed to putting Christ at the center of it all. He views our role as humble instruments to the greater glory of God through, in and with Christ - as majoram Dei gloriam - and thus, while having been a scientist all of his life, he has always tried to follow Christ?s teaching in Franciscan humility.
