Associate Professor of Chemistry, Iowa State University
Visiting Associate Professor 2014-2015
Hosted by Professor Timothy Swager, Department of Chemistry
Malika Jeffries-EL is an Associate Professor of Chemistry at Iowa State University. She received BA degrees in Chemistry and Africana Studies at Wellesley College in 1996 and Master’s and Ph.D. degrees in chemistry from The George Washington University in 1999 and 2002 respectively. After spending one year at Smith College as a Mendenhall Fellow she worked as a post-doctoral fellowship under the direction of Professor Richard D. McCullough at Carnegie Mellon University. In 2005, she joined the faculty in the Chemistry Department at Iowa State University and was promoted to associate professor with tenure in 2012.
Dr. Jeffries-EL's research focuses on the development of organic semiconductors–materials that combine the processing properties of polymers with the electronic properties of semiconductors. She has authored over 30 publications, received over 1200 citations and given over 75 lectures domestically and abroad. She has won numerous awards including the 3M untenured faculty award (2008), the Emerald Honors for most promising minority scientist (2008), the Lloyd Ferguson Award from the National Organization of Black Chemist and Chemical Engineers (2009), NSF CAREER award (2009), the ISU-College of Liberal Arts and Sciences Diversity Award (2011), the ACS-Women Chemist Committee Rising Star award (2012) and the Iota Sigma Pi Agnes Fay Morgan Award (2013). She also held the ISU Gregory L. and Kathleen C. Geoffrey Faculty Fellowship (2005-2008).
She is also a dedicated volunteer and has served in several activities within the American Chemical Society including the editorial advisory board for Chemical and Engineering News, the Society Committee on Education (SocEd), the advisory board for the Women Chemist of Color Initiative, Member-at-large for the Organic Division, Program co-Chair for the Polymer division and as a councilor for her local section. She also serves the community through her work with Alpha Kappa Alpha Sorority, Incorporated (AKA), whose Lambda Upsilon Chapter happens to be MIT's first and oldest sorority. Dr. Jeffries-EL is a native of Brooklyn, New York.
