# Malika Jeffries-EL

Malika Jeffries-EL is an American chemist and professor of chemistry at Boston University studying organic semiconductors. Specifically, her research focuses on developing organic semiconductors that take advantage of the processing power of polymers and the electronic properties of semiconductors to create innovative electronic devices. She was elected as a Fellow of the American Chemical Society in 2018.

## Early life and education

Jeffries-EL is from Brooklyn, New York and was the first in her immediate family to attend college. She was inspired to become a scientist by Mae Jemison, an American engineer, physicist, and astronaut who was the first black woman to travel to space. Jeffries-EL earned BA degrees in Chemistry and Africana Studies from Wellesley College in 1996. In 1999 she earned her master's degree in chemistry from George Washington University (GWU). In 2002, Jeffries-EL completed her PhD in Synthetic Chemistry at GWU. Richard Tarkka supervised her.

## Research and career

After completing her PhD, Jeffries-EL worked as a postdoctoral fellow at Carnegie Mellon University under the supervision of Richard D. McCullough from 2002 to 2005. While there, she worked on the synthesis and field-effect mobility of polythiophene. In 2005, she joined the faculty at Iowa State University and was promoted to tenure in 2012. Jeffries-EL works on organic semiconductors.
Jeffries-EL served as a Martin Luther King visiting professor at Massachusetts Institute of Technology between 2014 and 2015. Here, her group focused on the synthesis of polymer building blocks, including heterocyclic electron-rich (donor) and electron-poor (acceptor) units. For electron-deficient units, Jeffries-EL develops benzobisazoles. She is interested in cross-conjugated organic semiconductors, including benzodifurans, as well as functional Polythiophenes. She uses the materials for organic solar cells, transistors and light-emitting diodes.
In 2015 Jeffries-EL was selected as the 8th Annual Goldstein Distinguished Lecturer by Cal Poly Pomona College of Engineering. She was the keynote speaker at the 2016 Northeastern Section of the American Chemical Society meeting.
In 2016 she joined Boston University as a tenured associate professor.
