Dr. Justin B. Sambur is an analytical and materials chemist with extensive experience identifying the composition, structure, and failure mechanisms of materials. He specializes in determining the presence, absence, identity, and quantity of hazardous or regulated materials in complex systems, and he brings a deep, methodical approach to measurement, data integrity, and clear explanation of findings. Dr. Sambur has spent his career studying materials relevant to energy, sustainability, and advanced manufacturing. He is qualified to opine in matters involving battery, solar, and electrolyzer technologies, nanotechnology and nanoparticle synthesis and characterization, and general materials failures or contamination events.
Dr. Sambur earned his Ph.D. in Chemistry from Colorado State University in 2011 and was awarded a prestigious National Science Foundation Postdoctoral Fellowship to conduct research at Cornell University. Since joining the Colorado State faculty, his expertise in analytical and physical chemistry has been recognized with multiple national honors, including the Air Force Young Investigator Award, NSF CAREER Award, and U.S. Department of Energy Early Career Award. He has also been named a Sloan Research Fellow and Scialog Fellow in Advanced Energy Storage. He applies a broad suite of microscopy, spectroscopy, and electrochemical techniques to analyze metals, semiconductors, coatings, and contaminants.
Dr. Sambur is an expert in scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDS), transmission electron microscopy (TEM), Raman and photoluminescence spectroscopy, X-ray photoelectron spectroscopy (XPS), atomic force and scanning tunneling microscopy (AFM, STM), and electrochemical methods including SECM and SECCM. His analytical experience extends to chemical contamination, materials degradation, and product or process failure investigations.
At Colorado State University, Dr. Sambur teaches courses in analytical and materials characterization methods. He was recognized with the Norman Edmund Inspirational Award for Microscopy Education from Edmund Optics.
He has authored over 60 peer-reviewed publications in leading journals (Nature, Science, PNAS), presented over 75 invited lectures at Universities and Scientific Conferences, serves on the Early Career Advisory Board of Chemical & Biomedical Imaging, Executive Board of the Society of Electroanalytical Chemistry, Editorial Advisory Board of ACS Electrochemistry, Advisory Board for NSF’s Center for Single-Entity Nanochemistry and Nanocrystal Design and DOE’s Liquid Sunlight Alliance Hub.
Dr. Sambur is an award-winning educator and a clear, effective communicator in both written and oral testimony. He translates complex analytical data into findings understandable to technical and non-technical audiences in litigation, regulatory, and industrial contexts.
