Analytical Chemistry

Interests and Expertise

My research interests involve the analysis of archaeological and historic cultural heritage materials, primarily utilizing Direct Analysis in Real Time (DART) mass spectrometry.  Current research projects include: collaborative studies with the Detroit Institute of Arts on characterizing organic colorants in dyes and pigments; radiocarbon dating and chemical analysis of rock paintings; and characterization of archaeological residues.
