Biography

Dr. Ajay Mallia is an assistant professor of chemistry at Georgia Gwinnett College, Lawrenceville. Before joining GGC, Mallia worked as a research assistant professor at Georgetown University, Washington D.C., where he was involved in the design, synthesis and characterization of soft materials. Mallia also held faculty positions at University of Maryland, College Park, University of District of Columbia, Trinity Washington University and Montgomery College. Prior to Washington, D.C., Mallia performed research on metal nanoparticle preparations at City University of New York and erasable full color displays using liquid crystals at the National Institute of Advanced Industrial Science and Technology, Tsukuba, Japan. Mallia’s research work has appeared as a cover feature in many flagship journals, including Journal of the American Chemical Society, Chemical Society Reviews and Langmuir. He has published 39 peer-reviewed publications and presented his research work at various national and international conferences. 

Mallia is an active leader at national and local levels of American Chemical Society. He is 2017 chair-elect for the ACS Georgia Section. Mallia is secretary and a committee member of Project SEED national committee and a certified facilitator for ACS Leadership Development System. Before moving to Lawrenceville, Mallia has served Chemical Society of Washington as executive committee member, alternate councilor and chair of many of committees. For his volunteer service to American Chemical Society, Mallia was awarded E. Ann Nalley regional award and outstanding local section volunteer award in 2014.
