Dr. Pathirathna’s interdisciplinary and translational research focuses on developing and optimizing electrochemical sensors for the analysis of biologically and environmentally significant metals and neurotransmitters, with applications in point-of-care diagnostics. Her research has been supported by the Naval Research Laboratory and the National Science Foundation. Among her distinctions are the Outstanding Educator at a Research Institution Award from the American Chemical Society (ACS) and the Educator of the Year Award from United Bridge Inc. In addition to her academic and research roles, she has led STEM clubs at Palm Bay Middle School and Pineapple Cove Classical Academy, promoting hands-on science education for young learners. Dr. Pathirathna served as Secretary of the ACS Orlando Section (2021–2024) and currently serves as a reviewer for several scientific journals and funding agencies. Her commitment to advancing chemical education, research, and community engagement continues to reflect the mission and values of the ACS.
Dr. Meghan McGreal Candidate for Secretary
Meghan McGreal is an Assistant Professor of Chemistry at Stetson University in DeLand. She earned her undergraduate degree at the University of North Carolina at Asheville, and her master’s and doctorate degrees from the University of Minnesota – Twin Cities. She is a computational chemist with a research focus on metalloenzyme catalysis and biomimetic modifications to the active sites of these enzymes. Dr. McGreal is the faculty adviser to the Stetson University ACS Student Chapter and is a founding member of the Stetson Inclusive Pedagogy Faculty Cohort. Dr. McGreal is very passionate about undergraduate chemistry education, as well as providing connections and outreach opportunities for the public to experience chemistry.
