Dr. Aruna J. Weerasinghe serves as a Senior Lecturer and Research Mentor in the Department of Chemistry and Fermentation Sciences at Appalachian State University since 2013. Her research bridges analytical chemistry and environmental science through innovative detection methodologies for hazardous substances.
Her educational background includes:
- Ph.D. in Chemistry from Western Michigan University (2011)
- Bachelor of Science in Chemistry from the University of Peradeniya, Sri Lanka (2001)
Research focuses on designing rhodamine-B derivative sensors for metal ions (Cr3+, Fe3+, Cu2+, Hg2+, Ni2+) and chemical warfare agents (G-type/V-type nerve agents), alongside investigations into bacterial iron transport mechanisms involving synergistic anions like borate in marine environments. Her work combines organic synthesis, photophysics, and bioinorganic applications to address environmental and security challenges.
Publication analysis reveals consistent advancement in fluorescent probe technology from 2010-2016, demonstrating interdisciplinary impact across analytical chemistry, marine biochemistry, and defense-related detection systems. The portfolio shows progressive refinement from single-ion sensors to complex nerve agent detection platforms.
As a Research Mentor, Dr. Weerasinghe supervises student projects in chemical synthesis and sensor development. While specific grant funding isn't detailed, her collaborative publications with institutions like Duke University indicate active research engagement and methodological innovation in chemical detection.
