T hese knowledge gaps prevent control\, suppression or enhancement\, of comp eting reaction channels that can drive development of unprecedented cataly tic reactions. In this talk\, I will focus on our use of high-level quantu m mechanical calculations\, rigorously calibrated against experimental dat a\, to interrogate the mechanisms and to guide the development of new cata lysts and reagents for currently sluggish or unselective reactions. In par ticular\, I will focus on our use of combined experimental and computation al tools to understand and develop new (asymmetric) three-component iron-c atalyzed radical cascade/cross-coupling reactions.\n\n \;\n\nAbout the Speaker:\n\nOsvaldo was born in Mexico and raised in Sacramento\, Califor nia. He attended Sacramento City College and transferred to UCLA in 2006 w here he worked as an undergraduate at the laboratories of Prof. Houk. He o btained his B.S./M.S. in 2009 and completed his Ph.D. in 2012 (UC Davis) u nder the guidance of Prof. Tantillo. From 2012-2016 he worked as a postdoc with Prof. Kozlowski at the University of Pennsylvania where he used comp utational and experimental tools to study transition metal-catalyzed proce sses. In 2016 he started his independent position at the University of Mar yland College Park as an Assistant Professor\, and then Associate Professo r until 2021. In the Fall 2021\, he moved to Texas A&\;M University whe re his research combined computational and experimental approaches to adva nce our understanding of iron- and photo-catalyzed reaction mechanisms.\n\ nRecent news related to background:\n\nLINK \n\nLINK \n\nLINK  4:00 pm END:VEVENT END:VCALENDAR
