My
academic background is in Physics, and Nuclear Medicine and Radiobiology.
During my graduate studies I specialized in photonics, concentrating on
ionizing effects of laser pulses on different materials. This experience
enabled me to integrate radiation science with photonics, and provided me with
a unique and valuable expertise.
EDUCATION
- (2003-2005) Philosophy Program, University of Quebec at Montreal,
(Philosophy of Science, Logic, Philosophy of Language).
- (2000-2005)
Master of Science in Nuclear
Medicine and Radiobiology; University
of Sherbrooke, Canada (Thesis title: Description of water photoionization using
fs laser pulses at 790 nm in self-focusing regime. Potential applications
in the field of radiobiology.) Part 1 and Part 2 ; Reviewers' comments on my thesis (the original in French, and the English translation)
- (1995-2000) Bachelor of Science in Physics; University of Montreal, Canada
TECHNICAL
EXPERIENCE
- Designed and operated experimental setups for
interferometry, and pump-probe time resolved spectroscopy.
- Conducted time resolved fluorescence experiments.
- Maintained, calibrated, and operated a femtosecond
laser system (from SpectraPhysics), an optical parametrical amplification
system (OPA), and an ultra-short light pulse amplification system
(Spitfire).
- Designed and operated a detection/analysis system for a
pulsed laser system.
- Hands-on experience with data acquisition systems such
as Boxcar, National Instruments DAQ hardware, and GPIB & RS232
protocols.
- In-depth knowledge of LabView programming.
- Experience with diamond film deposition in a
surface-wave driven microwave plasma reactor.
- Laser material processing;
applications of pulsed lasers in medicine and biology; ionizing effects of
laser radiation on water, and biological targets (the physical processes
involved and the resultant chemical and structural transformations);
nonlinear optics; spectroscopy.
APPLIED RESEARCH
AND INNOVATION
- Currently developing a
laser-based system that enables the study of DNA damage formation, and DNA
repair machinery, with femtosecond time resolution.
- Currently developing a
laser-based material processing system; the dose
distribution is controlled by inducing a superposition of ionization
modes.
- Description
of water photoionization using femtosecond laser pulses at 790 nm, in
self-focusing regime.
- Proposed new and promising
applications of pulsed laser sources in the field of radiobiology and
radiochemistry.
