But an undergraduate stint in an organic chemistry lab changed that plan, setting him on a course that has since earned him a place among Nobel laureates, astronauts, inventors and innovators. The professor of chemistry at the USC Dornsife College of Letters, Arts and Sciences has been <a href=\"https:\/\/www.aaas.org\/news\/aaas-welcomes-449-scientists-and-engineers-honorary-fellows\" target=\"_blank\" rel=\"noopener\">named a 2025 Fellow<\/a> of the American Association for the Advancement of Science.<\/p>\n<p>Pratt arrived at the University of Arizona in 1995 to study math and biochemistry, with medical school as his long-term academic goal. That changed when the young undergraduate stepped into Professor Robin Polt\u2019s organic chemistry lab.<\/p>\n<p>\u201cI was hooked by the logic of chemical transformations and the ability to make molecules with my own hands,\u201d Pratt says. \u201cThat ability to forge molecules with precision, from drug-like compounds to full proteins, and using them to answer questions in biology is what gets me excited about what my lab is doing now.\u201d<\/p>\n<p>After earning his bachelor\u2019s degree in biochemistry and mathematics and studying glycosylation reactions \u2014 the bonding of carbohydrate molecules to proteins \u2014 under Polt\u2019s guidance, he moved on to the University of California, Berkeley, where he earned his PhD in chemistry in 2004 with future Nobel laureate <a href=\"https:\/\/www.nobelprize.org\/prizes\/chemistry\/2022\/bertozzi\/facts\/\" target=\"_blank\" rel=\"noopener\">Carolyn Bertozzi<\/a>. Pratt then completed an American Cancer Society Postdoctoral Fellowship at Rockefeller University in Professor Tom Muir\u2019s lab before joining USC Dornsife\u2019s <a href=\"https:\/\/dornsife.usc.edu\/chemistry\/\">Department of Chemistry<\/a> in 2009.<\/p>\n<p>Now in his 16th year at the College, Pratt studies the molecular and physiological effects of chemical alterations of proteins while mentoring a new generation of postdocs and PhD students, perhaps some destined for prestigious scientific honors of their own.<\/p>\n<p>\u201cHelping students and postdocs mature as scientists, promoting them, and getting to watch them go off and do amazing things is my favorite part of this job,\u201d Pratt says.<\/p>\n<p>\u201cAAAS Fellows have a responsibility to be examples of strong science and mentorship,\u201d he adds. \u201cI\u2019ve strived to do both of these things throughout my career, but the visibility of the honor makes it all the more important.\u201d<\/p>\n<p>Pratt says becoming a fellow also provides an important opportunity to contribute to the broader scientific community. \u201cOur profession faces challenges from a murky grant-funding landscape to reduced trust in science and scientific leaders. Our community needs to come together to address those issues, and I\u2019m excited to be a part of that effort.\u201d<\/p>\n\n\n\n<\/div>\n\n\n  <\/div><\/div>\n\n\n\n  \n        \n  \n
