Introduction
I have an Earth Sciences MSc degree from Carleton University where my research involved detailed mapping of tectono-magmatic structures on Venus using Magellan SAR images.
I am currently a Ph.D student at the University of Western Ontario within the Institute for Earth and Space Exploration. My current research investigates morphological comparisons between impact ejecta and pyroclastic flow deposits, as well as a re-examination of lunar impactites from the Apollo program.

Detailed mapping and analysis of rift systems on SAR images along Hecate Chasma, Venus. Addresses systematic difference between rift faults and graben fissures.
Parga Chasma is a discontinuous rift system marking the southern boundary of the BAT region on Venus. Along a 1,500 km section of Parga Chasma, detailed mapping has revealed 5 coronae, 11 local rift segments distinct from a regional extension pattern, and 47 graben-fissure systems. These systems are often centred within coronae or large volcanoes,...
Discusses some preliminary results of petrographic analysis on impactite and pyroclastic rocks to compare and contrast potential similarities in mineralogy, morphology, and texture between the different rock types.
Parga Chasma is a discontinuous rift system marking the southern boundary of the Beta-Atla-Themis (BAT) region on Venus. Along a 1500 km section of Parga Chasma, detailed mapping of Magellan Synthetic Aperture Radar images has revealed 5 coronae, 11 local rift zones distinct from a regional extension pattern, and 47 graben-fissure systems with radi...
There have been great advances in our understanding of planetary geology through recent and ongoing missions, such as Curiosity and Opportunity (Mars), GRAIL (the Moon), and MESSENGER (Mercury), but Venus is lagging behind. Since the Magellan mission (1989-1994), which provided radar mapping of more than 98% of the surface, there have been missions...
In 1989, NASA launched the Magellan mission to perform detailed radar mapping of 98% of Venus’ surface from orbit at a resolution of 75-100 m/pixel. This mapping was completed using Synthetic Aperture Radar (SAR) imaging. SAR takes advantage of the spacecraft movement to simulate a much larger antenna, thereby increasing spatial resolution. Using p...
Our sister planet Venus had always been clouded in mystery, until the Venera 4 and 7 capsules managed to pass through its atmosphere and relay back measurements about its surface geology and atmosphere. This led to the current understanding that Venus’ surface consists of temperatures in excess of 450oC and 9000 kPa of pressure, resulting from a th...
