Frans Harren

Frans J. M. Harren is Associate Professor at Radboud University, Nijmegen (the Netherlands). His research focuses on the reliable state-of-the-art sensing of minute quantities of trace gases in complicated gas mixtures, online, noninvasive, with high selectivity and detection speed. For this, photoacoustic frequency modulation, and cavity-enhanced spectroscopy are combined with quantum cascade lasers, optical parametric oscillators, and frequency comb lasers. These methods are applied within biology, agro technology, and medical sciences.
