Analytical Chemistry

Interests and Expertise

My research interests involve the analysis and dating of archaeological and historic cultural heritage materials. Our main analytical approach is with ambient ionization mass spectrometry methods, primarily utilizing Direct Analysis in Real Time (DART) with time-of-flight mass spectrometry. Current research projects include: collaborative studies with the Michael C. Carlos Museum (Emory University) on characterizing organic colorants in ancient textiles; radiocarbon dating and chemical analysis of textiles and rock paintings; and characterization of archaeological residues.
