H. Michael Heise is an Honorary Professor at the South-Westphalia University of Applied Sciences in Iserlohn. After his PhD in 1976 at the Christian-Albrechts-University in Kiel, he was a research associate at the School of Chemistry, the University of Western Australia, Perth. Since 1982 until 2013, he had been a senior scientist at the Leibniz-Institute for Analytical Sciences – ISAS in Germany with earlier appointments as Research Fellow at the German National Physical Laboratory (1979–1982) and the Federal Biological Research Centre (1977), both in Braunschweig, Germany. He was serving as editor of “Vibrational Spectroscopy” for the years 2011 – 2016, and since 2021 he is a member of the Editorial Board of “Biosensors”. He published 220 papers including chapters to textbooks and encyclopaedias, and is co-author of two textbooks on mid- and near-infrared spectroscopy, respectively. Research interests are in optical spectroscopy – Raman, UV/Vis, near-, mid- and far-infrared/THz spectroscopy – and chemometrics, especially with analytical applications to clinical chemistry, medical diagnostics and microbiology, as well as to environmental analytical chemistry, material analysis and recently in agricultural products. Instrument miniaturization based on optical fibres for process monitoring in biotechnology and industrial production is another field with a successful engagement.
