Alexis De Vos received his Ph.D. degree in applied sciences from the University of Ghent, Belgium, in 1979. He currently holds posts as part-time system engineer at the Flemish Interuniversity Microelectronics Research Centre (Imec), and as part-time professor at the epartment of Electronics and Information Systems (Elis) of the University of Ghent (UGent). His research focuses on material science (polymers, semiconductors, metals, liquid crystals), microelectronics (thin films and chips), and energy sciences (thermodynamics, solar energy, endoreversible engines, reversible and quantum computing). He has authored numerous papers and articles. He is author, co-author and coeditor of several books, e.g. the book Thermodynamics of solar energy conversion (Wiley-VCH, 2008).
