Thanks for stopping by! I am an Earth scientist (specialized in geophysics). I have researched about drumlins, glacial lake sediments, and rift tectonics. I like to work on my car, jam with friends, and sometimes code.

I generate a large number of numerical models of rifting (a geological process where continents break apart) where a small piece of the continent is detached from its parent plate. I implemented an efficient automated system that detect the instance of continental break-up. We identified a list of physical parameters that control the geological process.

Prof. Phil Herongeodynamics, numerical modelling, data visualization
I investigated the dynamics of rifting by conducting numerical models on UNIX-based supercomputers. I simulated multiple layers of rock with various physical properties undergoing extension for ten of millions of years. We identified a list of physical parameters that control the geological process.

Nadine Veillettegeophysical data analysis, scriptwriting
I processed and mapped preliminary geophysical data (e.g., magnetic, induced polarization, and gravity surveys) using Geosoft Montaj. I also developed map templates and control scripts for the software to streamline map production.

Prof. Nick Eylesseismic reflection profiling, stratigraphy analysis, glacial lakes
I analyzed stratigraphic profiles from a seismic reflection survey of Lac Simard, Québec, Canada. We identified two distinct sediment layers that reflect the changing depositional environment due to deglaciation since the Last Ice Age. We also identified soil disturbances could indicate ancient earthquakes or ice stream surge.

Prof. Nick EylesGIS, spatial data analysis, field work
I trained for AI processing of large Li-DAR data to help identification of glacial geological features (drumlins, glacial lineations, and moraines) on satellite images. I assisted with interpreting the past glacier dynamics (advance, retreat, and fast/slow movement of the ice lobe) by classifying and analyzing these glacial 'relics' using ArcGIS.
Rifting is a geological process in which a continent splits into two or more smaller landmasses. About 60 million years ago, a major rift occur at the North Atlantic and separated present-day Greenland, Canada, from the rest of Europe. Although the rift is geologically known, why it occured, as well as why a fragment of Greenland was stranded to Canada, remain enigmatic. We created numerical models with multiple layers of different rock properties, which simulated tens of millions of years of rock deformation to explore the effect of a pre-existing mountain belt on rifting. The results show the formation of a 100-150 km continental fragment, modelled after the Nain Province, Labrador, Canada.

The Western Quebec Seismic Zone is one of the poorly understood earthquake-prone area due to a lack of instrumental earthquake records and understanding of the background geology. Since lake sediments have been found to potentially record earthquake-related disturbance during deposition, a seismic reflection survey was carried out to map out the basin of Lac Simard, western Quebec. From the processed data, we identified two sediment sequences, one retaining lateglacial (~10-8 ka) records, and one postglacial, as well as acoustic facies that reflect disturbance of either tectonic origin, or from abrupt influx of meltwater when the entire region was covered by a thick, retreating Larentide Ice Sheet.

Mega-grooves are geological landforms left by glaciers and record information about the speed and direction of past glacier flows above the hard bedrock. As a glacier moves, it picks up subglacial material, which acts as an abrasive and can carve into the underlying bedrock. By examining these features, we can reconstruct the past glacial history of an area. Our study focused on measuring and documenting mega-grooves near Odessa, Ontario. The observed patterns reveal a southwest movement of the Ontario Lobe during the last glacial maximum, and the crossing striations suggest a northwest regression during deglaciation.
