He is the chairman of the permanent steering committee of Europt(r)ode (the biannual Eur. conference on optical chemical sensor and biosensors).

From the reviews: "This book is particularly summarizing the various types and developments in optical sensor technology during the past two decades, and gives also an insight to the future trends in this permanently growing field. This book is providing knowledge on a variety of optical sensor techniques ... and is, therefore, highly recommended to graduate students and experienced researchers, who are engaged in this interesting scientific field in academia and industry." (Advances in Food Science - AFS, Vol. 27 (1), 2005) "This book summarized various types of developments in optical sensor science over the past two decades with an insight to future trends. ... This book will be useful for scientists and students working in the field of optical sensors and biosensors, particularly modern immuno- and genosensors." (Chemia Analityczna, Issue 49, 2004) "This book provides a good overview of the state of the art in optical sensors for industrial, environmental and diagnostic applications. ... This unique book contributes a concise collection of knowledge to this highly interdisciplinary field ... . is an ideal starting point for interested readers and a valuable source of information to scientists. ... The high density of information together with a 'trend analysis' of future directions provides a highly valuable content to the readership."
