About

Dr. Jerome Thiebaud's focus has been on applied research in laser spectroscopy, chemical sensing, and gas analysis instrumentation since 2004. His work has been published in journals such as Applied Physics B, the Journal of Molecular Spectroscopy, the Journal of Chemical Physics, and Environmental Science & Technology. He holds two master’s degrees and a doctorate from the University of Lille, France. Jerome completed his training with two post-doctoral fellowships — at the University of Toronto and at SRI International in California. He served as senior scientist for companies such as Thermo Fisher Scientific and Los Gatos Research (part of ABB). He joined Aeris Technologies as director of R&D in 2014 and served the company as President from 2020 to 2024.

2004-2007

University of Sciences and Technology of Lille

Design of a continuous wave cavity ring-down spectrometer coupled to flash photolysis, near-infrared diode laser spectroscopy of HO₂, simultaneous OH monitoring by Laser Induced Fluorescence, kinetics and dynamics of reactions involving HO₂ and OH. Trace gas sensing of formaldehyde by wavelength modulated spectroscopy in the middle infrared.
2007-2009

University of Toronto

Design, test, and successful demontration in a 230 MW coal-fired power plant of an In Situ Optical Absorption Mercury Continuous Emission Monitor. Use of the ultraviolet atomic absorption from a mercury lamp by the elemental mercury Hg⁰ and a UV LED background correction system. This cross-stack approach allowed the in situ and continuous quantification of Hg⁰ during the operation of the power plant.
2009-2010

SRI International

Laser Spectroscopy of Reactive Species - Ozone Photodissociation and OH Radical Relaxation Studies - Laboratory pump/probe experiments including multiple pulsed lasers (excimer, dye, OPO) and sophisticated timing schemes to measure the rate constants of the deactivation of OH(ν).
2010-2012

Thermo Scientific

R&D and development of new laser-based gas analyzers operating in the Middle Infrared via Difference Frequency Generation and measuring greenhouse gases and atmospheric pollutants. Use of Laser Induced Fluorescence (LIF) to quantify formaldehyde with parts per trillion precision.
2012-2014
