Chris is an applied physicist with expertise in the fundamental physics of X-ray fluorescence (XRF) and charged particle spectroscopy techniques. Prior to JPL, while at the University of Guelph, Chris supported the analysis of data returned from the alpha-particle X-ray spectrometer (APXS) instrument installed on NASA’s Curiosity rover.
Here at JPL, Chris serves as a co-investigator and elemental calibration lead for NASA’s Planetary Instrument for X-ray Lithochemistry (PIXL), an instrument installed on the arm of the Mars 2020 Perseverance Rover. Also at JPL, Chris leads an instrument team working to develop a prototype X-ray that utilizes pyroelectric technology for in situ planetary and lunar exploration. Chris hopes to develop the prototype instrument so that it might serve as a low-cost, low-power, robust alternative to existing radioactive and X-ray tube source technologies.
Chris also maintains a long-lasting interest in pure scientific research, directed at improving physics fundamental parameters used in X-ray spectroscopy analysis.
Chris serves as an academic reviewer for articles written within the field of X-ray spectroscopy from journals: Icarus, the Journal of Synchrotron Radiation, Advances in X-ray Analysis, Nuclear Instruments and Methods A and B and X-ray Spectrometry.
Following the success of the Perseverance Rover landing, Chris has participated in multiple interviews and has delivered several public talks to share his experience on the Mars 2020 mission.
Chris continues to mentor students through the JPL Summer Internship Program and periodically teaches undergraduate and graduate students as a sessional lecturer.
