Crisan Popescu

Dr. Crisan Popescu received his degree in chemical engineering / textile chemistry from Shanghai Textile Engineering Institute (now Donghua University) and PhD degree in physical chemistry from the University of Bucharest. He worked in textile industry, textile research and academia as professor of textile chemistry. Sponsored by German Academic Grants (DAAD) and German cosmetic industry during 1990s he spent several short spells at The German Wool Research Institute (now DWI Leibniz Institute for Interactive Materials) in Aachen. Later on, he joined the Institute and worked, as a project leader for keratin related projects (wool and hair cosmetics), for 15 years, then moving to hair care industry as a Senior Research Scientists with Kao Germany GmbH.

Dr. Popescu acted as Chairman of the “Product Group” of the International Wool Textile Organization, IWTO (2010 – 2015) and serves as Chairman of the Scientific Commission of International Confederation of Thermal Analysis and Calorimetry, ICTAC (since 2012). He was member of the organizing committees for several international conferences on thermal analysis, textiles, and hair, and delivered over 50 invited presentations.

His 160 published papers covers the areas of his scientific interest which span from kinetics of heterogeneous processes and dyeing and finishing textile fibres to physics of polymers and bio-polymers with a focus on keratin.

Currently, Dr. Popescu is working in hair research and in non-isothermal kinetics, and as a consultant for hair care industry and wool industry.
