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 40 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 was 2018 chair and currently past-chair of American Chemical Society 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.
Teaching philosophy: Teaching is a complex social responsibility that has great impact on the society, as one of the old saying, “teaching is a profession that teaches all other professions. As an educator Mallia hopes to inspire future scientists to meet any challenge with confidence and thus produce creative, competent problem solvers.
