Mark Biesinger

Dr. Mark Biesinger serves as the Director of Surface Science Western (Western University), Canada's leading surface analysis and materials characterization facility, and holds the position of Adjunct Research Professor in the Department of Chemistry. With over 30 years of experience operating and maintaining XPS, SEM/EDX, optical microscopes, and SIMS instruments, he is internationally recognized as an expert in X-ray photoelectron spectroscopy (XPS).

Dr. Biesinger has authored or co-authored over 90 peer-reviewed publications, including numerous seminal works that have significantly advanced XPS methodology and data interpretation techniques, particularly for transition metals. His recent research (2023-2025) focuses on resolving persistent challenges in XPS analysis such as peak fitting errors, oxygen spectra interpretation, and chemical state analysis of low-Z elements. He maintains the widely-used X-ray Photoelectron Spectroscopy (XPS) Reference Pages, a comprehensive resource for researchers worldwide. His work bridges fundamental surface science with practical applications in corrosion, mineral processing, and biomedical materials.

Dr. Biesinger has received prestigious recognition including the 2025 UKSAF Vickerman Prize, the 2025 Chemistry Research Excellence Award from Western University, and the 2022 American Vacuum Society Peter M.A. Sherwood Mid-Career Professional Award. He has been listed among Stanford's Top 2% Scientists since 2018.

As Secretary-Treasurer for the Surface Science Division of the Chemical Institute of Canada, Dr. Biesinger actively contributes to the scientific community. He currently collaborates with Natural Resources Canada (CanmetMINING) on research projects related to temperature effects on collector performance for lithium ore flotation, demonstrating his commitment to applied research with industrial relevance.
