My research focuses on the study of heat and fluids deep within the Earth's crust and upper mantle. Much of the work is large scale, looking at continental to global scale patterns of heat flow and crustal radioactivity, or regional utilizing electromagnetic soundings and laboratory measurements to understand crustal hydration. Lately, my work has drifted into global geochemistry and data analytics, specifically looking at temporal evolution of granites and the sources of variability in radiogenic heat production.

Several projects have required the compilation of large datasets including the Global Heat Flow Database (http://www.heatflow.org) and a global geochemical database (https://doi.org/10.5281/zenodo.2592822). I also have been releasing some of the codes that I used to analyze and process the data on GitHub (https://github.com/dhasterok), which includes links to codes for global geochemistry, protolith prediction, and global plate and province models.
Here's a video about the Global Geochemical Database that my group has compiled.

Understanding the future stability of of Antarctica's ice sheets are extremely important to mitigating the potential for sea-level rise associated with global warming. One of the key parameters in these models is the basal thermal conditions of the ice sheet. Our ARC discovery project aims to produce accurate estimates of crustal heat production, temperatures and geothermal heat loss that can be used to improve glacial models of ice flow and growth/retreat.

Deep (electrical) fluid pathways which extend to the near surface of the Earth are associated with some world-class mineral deposits. In this project, we investigate the effect of hydration on the electrical conductivity of the lower crust and the interpretation of deep electromagnetic soundings of the crust including the potential for identification of deep fluid pathways.

I am the honours degree coordinator in Earth Sciences. If you wish to study an honours degree, feel free to contact me. To submit an application, you can submit an expression of interest on the Faculty of Sciences website. For a sampling of the types of projects that we have on offer you may peruse our program booklet.
Geophysics IIIA/IIIB – an introduction to geophysical fields and their application to the Earth. This course is primarily theory-based, exploring the physical properties of the Earth and their effect on gravity, magnetic, and temperature fields (IIIA), and electrical and seismic fields (IIIB). We relate the physical theory and mathematics to develop simplified models of the Earth that provide insight into its gross composition, structure and evolution.
Tectonics III – examines the prevailing theories for how the solid Earth evolves, with a focus on plate tectonics. In this course, we discuss how to identify tectonic processes and their physical controls, boundary forces, and surface expression and temporal evolution. We also cover non-tectonic processes that help us understand tectonics and widen the theory to a whole Earth theory for mantle convection. We wrap-up by exploring the evidence or lack thereof for tectonics within the solar system.
Geoscience Data Analysis – A short course for honours students covers a wide range of data analysis techniques used in Earth Sciences. The course is about a week long and covers topics in basic statistics, hypothesis testing, regression, multidimensional data visualization and analysis, geospatial visualization and interpolation, time-series analysis, and issues related to geochemical data.
Other courses I have taught in the past include:
- Earth's Interior I
- Geology for Engineers
- Exploration Methods III
