Dr. Christopher’s current research focuses on developing reference analytical methods for the determination of trace elements in NIST Standard Reference Materials, research on petroleum materials, isotopic chemical forensics measurements via multicollector ICP-MS, investigating novel instrument couplings, and solid-sampling and imaging research using laser ablation interfaced to ICP-MS. He is an adjunct professor at the Medical University of South Carolina’s Marine Biomedicine and Environmental Sciences Center.
Dr. Christopher has 20+ years of research experience in plasma-based spectroscopies, including inductively coupled plasma and glow discharge plasma mass and emission spectrometries, sector field ICP-MS and multicollector ICP-MS; Comprehensive knowledge of analytical instrumentation and method development for quantification of trace elements; experience with trace element and isotopic chemical separations and microwave sample decomposition methodologies; application of quantification strategies employing high-accuracy measurement and calibration schemes, including isotope dilution mass spectrometry, method of standard additions and mercury quantification methods.
