Introduction

Kristin L. Bunker, Ph.D. in Materials Science and Engineering, is currently a Senior Scientist at RJ Lee Group, Inc., where she specializes in the analysis and characterization of materials utilizing ultra-high-resolution electron microscopy and X-ray spectroscopy techniques. She directs and conducts forensic examinations of particulate, nanomaterials, coatings, and thin films in advanced materials, environmental, manufacturing, and pharmaceutical projects. Dr. Bunker works closely with industry, national laboratories, and government agencies in the evaluation of nanoparticles from an industrial hygiene and environmental perspective. She is an expert in the characterization of various nanomaterials used in sensors, diagnostics, aerospace composites, architectural products and protective coatings among others. Dr. Bunker became the President of the internationally recognized Microanalysis Society (MAS) in 2012, and served a two-year term through 2014. She is the author or co-author of more than 40 publications covering topics in semiconductors, life sciences, mineralogy, and nanomaterials. Prior to receiving her Ph.D., Dr. Bunker served as an expert witness in California courts for the analysis of Gunshot Residue (GSR).
