TEACHING INTERESTS
As a teacher I focus less on imparting knowledge to students and more on developing their ability to practice the scientific method. To this end, I prefer using problem-based (“active-learning”) approaches instead of traditional lecture-based instruction. My favorite exercise of this type is the field mapping test, in which students spend a few hours independently determining the geological evolution of a site. The value of this exercise is the rapid iterative use of the scientific method that it requires. As the students start their work, they come up with ideas for how the site evolved, and then they collect data to test these ideas. They generate new ideas in response to the new findings, and then proceed to test these new ideas – thus continually completing and restarting the method of multiple working hypotheses. At the end of the field mapping day, they turn in their maps and we do a walk-through so that they can get immediate feedback. With enough experience of this kind, geoscience students become relatively fearless in tackling new problems. To my knowledge, a well-chosen field mapping exercise offers more rapid scientific method use than any other standard geology learning approach. This is a key reason why field teaching persists as a valuable learning experience for future geo-scientists of all disciplines.
This focus on independent discovery is one of the core elements of my teaching philosophy. The other is communication. I communicate to students in a variety of ways because students learn in a variety of ways. Also, I want students to be adept at communicating science. Therefore I assign a lot of informal and formal projects, to groups and individuals, which involve a range of communication components. For instance, in some of my advanced undergraduate / graduate classes, students construct Wikipedia articles complete with production of at least one original figure. This project has advantages over my prior approach (a term paper), including higher perceived responsibility (the pages are public!), more feedback (any Wiki user can comment on and alter the page), and stronger citation practices (this may seem surprising, but the Wiki community may be nearly as determined as the scientific community to require appropriate citation, and undergraduates understand the need for robust citation readily in the Wiki context). The ongoing success of the students undertaking these projects can be observed at the following page, where links to all 108 articles they have created across eight semesters are listed: https://en.wikipedia.org/wiki/User:Aagwebb .
The Wikipedia project was originally motivated by the Communications-across-the-Curriculum (CxC) program at Louisiana State University. At the University of Hong Kong, we have in turn used this project and the CxC program as the inspiration for our Communication-intensive Courses (CiC) initiative. CiC is a nascent university-wide course badging program (hosted by our Centre for Applied English Studies in partnership with our Centre for the Enhancement of Teaching and Learning) that will certify and highlight courses delivering extraordinary disciplinary communication training in written, spoken, visual, and/or digital modes.

RESEARCH INTERESTS
Our research group explores tectonic processes and their interactions with other planetary systems. Early work focused on testing and developing models for the construction of the Himalaya, Earth's premier natural laboratory of continent-continent collision. Continuing Himalayan research centers on Earth system interactions across the mountains, from mantle dynamics to the development of biodiversity. More recently a major interest has been tectonics of early Earth and development of hot terrestrial planets – for which rapid volcanic resurfacing appears to be a major, underappreciated control on long-term evolution. Other ongoing projects explore (a) salt extrusion dynamics and surface processes in China, Iran, and Israel, and (b) tectonic, climatic, and anthropogenic impacts on the Mississippi River delta.
RESEARCH APPROACH
We use geologic mapping integrated with analytical research to dissect the architecture and evolution of complex tectonic systems. Principal analytical tools are geo-/thermo-chronology and balanced palinspastic reconstruction, by which timing, rates, and magnitudes of deformation are determined. As our range of interests expands, we increasingly pursue collaborative research employing a range of techniques (e.g., geochemistry, geodesy, numerical modeling, petrology, remote sensing, sedimentology).
