Klaus Peter Geigle received his Diploma and PhD in Physical Chemistry, specifically on laser-based characterization of cold, isolated polycyclic aromatic hydrocarbons (PAH) in combination with quantum chemical spectroscopic computations, at the University of Cologne.
Since 1999 he is focusing on experimental characterization of sooting atmospheric and pressurized flames as member of the department of combustion diagnostics, part of the Institute of Combustion Technology at DLR. Main tool of those flame studies is laser-induced incandescence (LII) which he develops and applies in laboratory applications as well as at technical test rigs at other sites. Combination of planar LII for soot imaging with other laser-based imaging techniques is also part of his scientific task. The generated detailed and accurate data sets frequently serve for validation of numerical combustion models or soot kinetics, and improve the understanding of processes related to soot formation in turbulent pressurized flames.
Beyond this, KP Geigle serves as member of the scientific committee of the series of International Workshops on Laser-Induced Incandescence, co-hosted the recent workshop in Tutzing, Bavaria, in 2018, and is co-organizer of the International Sooting Flame (ISF) workshop series. Those workshop series focus on understanding, advancement and applications of the technique LII, and an improved understanding of soot formation aiming at technical applications, respectively.
He has authored or co-authored more than 40 refereed publications and several conference contributions, and is member of the German section of the Combustion Institute.
