Rachel Roller, Ph.D.
Assistant Professor of Chemistry
Belhaven University
Dr. Rachel M. Roller is an analytical chemist with expertise in paper microfluidics, pharmaceutical quality screening, chemical education, and the history and philosophy of science. Dr. Roller employs paper microfluidics in inquiry-based chemistry labs for in-person or remote learning, as well as for illicit drug detection and to screen for substandard and falsified pharmaceuticals in low- and middle-income countries. Her work on scalable paper-device fabrication methods includes a patent application for roll-to-roll manufacturing of air-gap paper analytical devices.

S. Ariel Kelley, Ph.D.
Associate Professor of Chemistry
Belhaven University
Dr. Kelley’s research group focuses on synthesizing novel nitrosamines and probing their behavior with advanced techniques, including NMR, FTIR, UV-Vis, and X-ray diffraction. A central goal is to trap reactive nitrosamine intermediates in cocrystals using supramolecular strategies, enabling detailed study of their chemistry while reducing environmental risks. At a primarily undergraduate institution, she mentors students closely, giving them hands-on experience with state-of-the-art instrumentation and experimental design.
