Accepting students

I run a very small group but the problems on which I work are varied.  Current questions in which I am interested include (please also see publications):

1) Why do the largest volcanic eruptions in the geological record have an equivocal expression in Earth’s record of climate change? How did the eruption dynamics governing the injection of a SO2-rich plume into the stratosphere during the 1991 eruption of Mt. Pinatubo ensure a large effect on global climate change? Why did the more powerful 2020 Hunga Tonga eruption through a shallow ocean produce virtually no effect? What if the climate effects of a massive Yellowstone-style eruption simply do not matter very much?

2)  Can the particle-scale microphysics governing the injection, spread and residence times of volcanic clouds provide critical clues to the ecological consequences of dissolving metal-particle-rich plumes produced during imminent deep-sea mining operations? Can we use the sensitive dependence of the dynamics, structure and longevity of volcanic clouds on vent source conditions to optimize the engineering of deep-sea mining operations to minimize ecological risks and impacts?  

3) To what extent can we use the structure, planform and morphometry of valley systems inferred from satellite and ground-based remote sensing data to constrain rigorously the history and cadence of glacial-interglacial cycles on Earth? What about the history of water and ice on ancient Mars? 

4) What are the “frequency response properties” of high-Arctic landscapes? How are their evolving  and varied responses in space and time to global warming and to unprecedented intensified summertime temperature variability manifest in the structure and evolution of landscapes, in the delivery of surface water, sediment, nutrients and pathogens into watersheds, and through consequence for at-risk Indigenous populations? How do we best characterize this response with satellite- and ground-based remote sensing studies? How do we incorporate Indigenous “Local Ecological Knowledge” (LEK) into this analysis and into the development of optimally-useful risk-assessment tools like “Apps”?

5) How does the intermittent assembly and breakup of supercontinents modulate Earth’s climate through transient effects on mantle convection, volcanism, mountain building, sea level change, weathering and the diversity of the biosphere?  What are consequences for Earth's atmosphere, ocean and biosphere and how are these effects expressed in proxy data? 


Student Opportunities: 

I look for graduate students with strong backgrounds in geology/volcanology/petrology/planetary science (with additional substantial coursework in math, physics and/or chemistry), astrophysics, physics or engineering, who love the challenge of independent research and who are fired up about working on problems in Earth and planetary science. I select for openly thoughtful, creative and challenging students who ask lots of questions and who like to play by their own rules.

I have no plans to accept new students for the fall of 2023. However, if you would like to argue your case, please email me.  Please include some discussion of the sorts of scientific questions/problems that you find interesting and why. I want to hear what you think. I want to hear also about what inspires you. If you have written papers or theses I would be keen to see them.  If you have other interests in addition to science I would like to hear about these as well.  What is the most recent book you have read? What is your favorite book of all time? If you have practical experience from working in a lab, a machine shop, a woodworking shop, on a construction site etc. or you just like to build things then please let me know. 


Postdoctoral Opportunities: 

Please email me. The tricky issue is always funding. Virtually all North American funding deadlines for proposals for postdoctoral fellowships in Canada are in September and October.

Effective teaching is very important to me. My goal in the classroom is to create an environment in which knowledge is constructed by students more than it is presented by me. Said differently, I have found that an effective way €œto teach science€ is simply to do science in the classroom, with my role being mostly a coach. As an example of what I mean, think of how coffee in an insulated mug without a lid cools to the overlying air. To explain this problem in a class it is easy to envisage a series of lectures that would break the issue of how hot coffee cools down into the main components of the science of thermal convection. However, no matter how brilliant my explanations might be, it is infinitely more engaging and inspiring to simply place a drop of cream in the coffee and study how the motions driven by the surface cooling disperse the cream, and hence distribute the cooling over the full depth of the coffee. To illustrate my approach more formally, in the classroom we (the students and me) begin an analysis of the cup of coffee as a team. The first step is to describe in detail everything we can observe about the cup, the coffee, and the drop of cream. Next, we formulate questions aimed at deciphering the driving dynamics of the cooling problem. These questions lead, in turn, to further inquiries about the physics of the problem that could take us first to textbooks and then to research articles. Following a careful study of the physics of the problem we would formulate hypotheses designed to unravel in a clear way precisely how the coffee cools. To test these hypotheses we would develop a list of good experiments to do and then we would do them. At the end of this study the students would have learned the significance of the scientific method, how to formulate and solve problems and, ultimately, how to construct knowledge in small and careful increments—i.e. learn.
