Andre Conjusteau, Ph.D.

André completed his undergraduate degree in the Chemistry Department at Université de Sherbrooke, Québec, Canada. Following graduation, he pursued a Masters degree in Theoretical Chemistry simulating the behavior of molecular ions in intense laser fields.

He then promptly moved to the United States and enrolled at Princeton University. Leaving theory aside, his Doctorate thesis focused on high-resolution spectroscopy of molecules embedded in superfluid helium nanodroplets. He made extensive use of microwave, infrared and ultraviolet radiation, and his thesis relied almost exclusively on devices either custom-built or heavily modified in-house.

During his last semester at Princeton, he was awarded a Robert A. Millikan Postdoctoral Scholarship at the California Institute of Technology. His work with the Physical Measurement and Control group focused on the development of “wet mirror” cavity enhanced absorptive spectroscopy, both in the infrared and the ultraviolet.

Following his tenure at Caltech, he moved to Houston, Texas and has since been Research Scientist at Fairway Medical Technologies. He designs and builds broadband optoacoustic transducers, and devises realistic testing apparatuses and protocols. As he’s been directly involved with radiation sources for over a decade, he also helps interfacing lasers to the optoacoustic systems FMT develops. When entropy prevails, he also serves as resident laser mechanic.
