uOttawa Geophysics

Our group’s research addresses fundamental questions concerning the evolution and dynamics of the solid Earth as revealed by geophysical data. The objective of our research program is to constrain the role of geological structure on the dynamics of active ocean-continent tectonic systems. For example, a lot of our active projects involve characterizing convergent and transform ocean-continent plate boundaries and elucidating the growth and fate of large cordilleras. Our work is informed by robust statistical analysis and modelling of seismic and geophysical data collected from a number of sources. Our tools of predilection include the processing of large quantities of broadband seismic data obtained from public archives. We develop and make publicly available a lot of our numerical tools - check out the Software page. We also install our own seismic monitoring stations - check out the Field page.

Canadian Cordillera

The Canadian Cordillera is a large, elevated and deformed landmass in western Canada created and shaped by the forces of plate tectonics. Our group uses seismic data to produce images of its deep internal structure that give insight into its past and current tectonic activity.

Data Science

Seismology and geophysics are data-rich fields with fully open data sets. Our group develops methods rooted in signal processing and statistical learning to extract insightful information on geophysical processes and Earth structure from large data sets.

Elastic thickness

The elastic thickness of the lithosphere is a measure of the stiffness of tectonic plates, and can be used to investigate its thermal and rheological structure. Our group develops wavelet analysis techniques to estimate its distribution on Earth and terrestrial planets

Ocean-bottom seismology

Most tectonic plate boundaries are located offshore, away from land-based seismic investigation. Our group works toward increasing marine seismic coverage using ocean-bottom seismic (OBS) stations to study plate tectonics in the oceans using OBS data.

Subduction zones

The rubbing of tectonic plates at subduction zones produces the largest and most lethal earthquakes. Our group studies the geological environment where these earthquakes occur using seismic imaging methods.


We believe in open science and open-source software. These are some of the computer programs that we developed. Please feel free to fork the repositories on GitHub, improve the codes, and send your feedback!
