Canadian Mission
POET Mission
Photometric Observations of Exoplanet Transits â a dedicated Canadian microsatellite space mission concept designed to discover, track, and characterize alien atmospheres.
Professor of Physics & Astronomy at Bishop's University and NASA Exceptional Achievement Medalist. Working at the interface of observational astronomy, deep space missions, Bayesian dynamics, and hands-on retro silicon engineering.
Leading observational programs and software pipelines to discover, model, and characterize exoplanets with NASA, the Canadian Space Agency, and international consortia.
From discovering planetary candidates with NASA's Kepler Space Telescope in California to leading the Canada Research Chair in Exoplanet Astrophysics in Quebec.
My primary research focuses on discovering and characterizing extra-solar planets. I specialize in precision transit photometry, transit timing variations (TTV) to measure planetary masses, and transmission spectroscopy to peer into alien atmospheres.
As a participating scientist on NASA's Kepler and K2 missions, I developed foundational pipelines for transit modeling and cataloging thousands of exoplanets that redefined our understanding of planetary architectures.
Based at Bishop's University in Lennoxville/Sherbrooke, Quebec, my lab is supported by the Canada Research Chairs program and the Canada Foundation for Innovation (CFI).
We run dedicated high-performance computational clusters and scientific infrastructure to analyze data from space observatories, mentoring both undergraduate and graduate researchers on real-world space mission data.
Beyond the stars, I am a passionate builder of retro-computing hardware, FPGA sound synthesis, and microcomputer architectures.
I actively write games and tools for the RP6502 Picocomputer, develop custom hardware cartridges for the Atari 2600/7800, synthesize classic Yamaha OPL2 audio on FPGAs, and publish open-source scientific code.
A crowning achievement in Kepler mission science: uncovering a rare seven-planet resonant system bathed in radiant heat.
In our updated Kepler candidate catalogue, we uncovered Kepler-385 (KOI-2433): one of only a handful of known systems with more than six confirmed planets. All seven planets are larger than Earth but smaller than Neptune, bathed in intense radiation from an F-type star 10% larger and 5% hotter than our Sun.
Active programs spanning flagship space telescopes, Canadian nanosatellites, and open-source scientific software.
Canadian Mission
Photometric Observations of Exoplanet Transits â a dedicated Canadian microsatellite space mission concept designed to discover, track, and characterize alien atmospheres.
NASA Mission
Over a decade of foundational mission science: candidate vetting, transit fitting algorithms, planetary radius distributions, and multi-planet architectures.
Flagship Observatory
Member of the Canadian NIRISS instrument team. Guaranteed Time Observations (GTO) extracting spectro-transits to probe atmospheres of transiting exoplanets.
CSA Microsatellite
Extracting high-precision stellar photometry and studying comets, near-Earth asteroids, and transiting exoplanets using Canada's space surveillance satellite.
Nanosatellites
Fleet of optical nanosatellites performing continuous, high-precision photometry of the brightest stars in the night sky to understand stellar pulsation and structure.
Orbital Dynamics
Gravitational perturbations between planets create minute deviations in transit timing, enabling mass and density measurements of planets without radial velocity data.
Open Source Pipeline
Open source Fortran and Python codebases developed to find, model, and manipulate planetary transits across large photometric datasets.
High Performance Computing
High-performance N-body gravitational integrators written in Julia, and GPU-accelerated Box Least Squares (BLS) algorithms for rapid transit searches.
Canada's Space Heritage
Microvariability and Oscillations of STars â Canada's first space telescope. Pioneered optical space photometry for asteroseismology and early exoplanet searches.
Empowering students with hands-on astrophysics, astronomical instrumentation, and scientific programming.
Upper-level course covering stellar atmospheres, nucleosynthesis, exoplanetary transit dynamics, and modern cosmological models. Includes computational simulations in Python and Julia.
Course Materials & Data →Observational training using our campus telescope. Students conduct hands-on CCD photometry, astronomical image calibration, and stellar spectral analysis.
Department of Physics →Undergraduate and graduate students in my lab work directly with space mission data from Kepler, TESS, and JWST, co-authoring peer-reviewed publications.
Student Research Profiles →Awarded by NASA for groundbreaking development of exoplanet validation pipelines and candidate catalogs for the Kepler Mission.
Recognized by Clarivate Analytics / Web of Science as one of the world's most influential and frequently cited scientists.
Appointed Canada Research Chair in Exoplanet Astrophysics, with ongoing CFI research infrastructure funding.
