Biography


Dr. Riegner has been teaching in the Department of Chemistry and Life Science since 1994. She earned a B.S. in chemistry from the University of North Carolina at Chapel Hill, and as an undergraduate she was involved in analytical chemistry research and taught general chemistry labs as a teaching assistant during her senior year. She received a DuPont Summer Resident Research Fellowship and graduated with Honors in Chemistry. At the University of Texas in Austin, Dr. Riegner focused on the development of mass spectrometry and various new types of ionization and detection. While at UT, she received a Monsanto Graduate Fellowship, the H.R. Henze Teaching Excellence Award, and a Professional Development Award. Upon completion of her PhD. in Chemistry in 1993, she conducted post-doctoral research at the University of North Carolina at Chapel Hill, where she designed and built ionization sources for research using ion trap mass spectrometry detection.

As a faculty member in the Chemistry Program, Dr. Riegner is continuously involved in curriculum development, assessment of the Chemistry Major student outcomes, and maintaining American Chemical Society Certification of the Chemistry Program. Dr. Riegner is a member of and the Faculty Advisor for Gamma Sigma Epsilon, the National Chemistry Honor Society. She is also a member of the American Chemical Society (ACS) and she and her research cadets annually present their work at the local and national ACS meetings. At the Academy level, she is currently serving as co-chair of the Middle States Reaccreditation Governance Working Group. She serves as a Department Academic Counselor and as an Officer Representative for Army Women’s Volleyball. Additionally, Dr. Riegner serves as a mentor for the in-coming junior faculty during the Faculty Development Workshops.

 

Ongoing Research Projects


Dr. Riegner’s research efforts have focused on protecting soldiers by evaluating potential chemical detection technologies, developing new materials for sensing, and characterizing these materials for improved detection. Her research teams work to detect both chemical warfare agents and explosives using a variety of spectroscopic techniques and incorporation of nanoparticles. Additionally, her expertise in chemical analyses makes it possible for her research teams to make significant contributions to a variety of collaborative research endeavors. Examples of these endeavors are studying melt glass for nuclear forensic applications, analysis of firing range lead contamination in the biota, and design and analysis of chemical simulants for munitions filler in high energy laser studies.
