Kim Esbensen TOS forum is edited by Professor Kim H. Esbensen. Kim is an international expert and consultant in sampling (Theory of Sampling, TOS), chemometrics and PAT (Process Analytical Technology). Through a 35-year academic career involving three professorships, he has conducted R&D across a wide range of application fields, primarily in process industries (mining, minerals extraction and processing, bio-fuels, recycling, environmental monitoring, nuclear waste) in environmental science a.o. In 2015 he established an international consultancy (KHE Consulting). Esbensen has been responsible for a university educational programme straddling 30+ years in chemometrics, PAT, TOS, instrumental analysis, Multivariate Image Analysis (MIA), process technology and Philosophy of Science, currently in the form of a continuing education curriculum offered via KHE Consulting. His CV lists ~300 publications and ~400 lectures/presentations. He is a recipient of the Pierre Gy Sampling Gold Medal (2013), and the Russian Chemometrics Society Gold Medal (2012). In 2003 he inaugurated the biannual series of World Conferences on Sampling and Blending (WCSB), now in its 10th edition—https://wcsb10.com. As well as editing TOS Forum, Esbensen is editor of the Sampling Column in Spectroscopy Europe/World. Esbensen’s credentials are documented in full at KHEC’s website: https://kheconsult.com. He is currently involved as a consultant in projects BESTE and NOIR (BELGOPROCESS).
