I received my PhD degree in Geophysics from Harvard University under the guidance of Professor Adam Dziewonski, whose passion and vision for seismological research are unparalleled. I minorred in computer science during my graduate studies, but the field evolved so fast that I am way behind today's technologies, at least according to my 'ever-encouraging' graduate students. I am currently the associate editors of Surveys in Geophysics and Journal of Seismology.
In my pastime I passionately follow the National Football League, especially Tom Brady and the big, bad New England Patriots, the reigning Superbowl Champ from 2014!
My main research areas are regional seismology and tectonics, seismic sources and inversions. My favorite depth range is the mantle transition zone where major mineralogical phase changes of olivine and garnet take place. More recently I have been focusing on regional tectonics beneath Western Canada Sedimentary Basin. Under the help of students and departmental technicians I was able to deploy a series of broadband seismometers in various parts of Alberta. This array (CRANE) is now the backbone for the regional seismic monitoring, especially pertaining to induced earthquakes by wastewater or fracking injections, as well as for the investigations of crustal and mantle seismic structures. I love computations and occasionally dabble in research pertaining to ultrasonic waves in bones.
Love teaching in general. Students need to keep space though since I could get quite animated in class. Not the most organized person but do my best to make classes interesting.
Seeking qualified graduate students who are interested in
(1) Regional crust and mantle seismic structure analysis
(2) Induced earthquakes
(3) Global seismic imaging
Due to the lack of departmental funds, interested students are strongly encouraged to apply for external scholarships such as CSC (Chinese Scholarship Council). Scholarship recipient's chances of admission to our graduate program (which is getting harder by day) are substantially better than the rest.
This course presents an overview of the interior structure, composition, dynamics and evolution of the Earth, Planets and Moons. Topics to be covered include: formation of the solar system; planets and exoplanets; the plate tectonics revolution; mountain building and continental dynamics; earthquakes, volcanoes and other geo-hazards; Earth's interior structure and dynamics from seismology, gravity and magnetism; the rotational dynamics of planetary bodies; mantle convection and dynamos. Prerequisites: one of MATH 101, 115, 118, 146; one of PHYS 124, PHYS 144, or EN PH 131, and one of PHYS 126, PHYS 146, or PHYS 130. Note: credit will be given for only one of GEOPH 110 or GEOPH 210.Fall Term 2022
A variety of seismic and ground penetrating radar data sets are obtained by the student during field school; these data are corrected, enhanced, and imaged in a computer workstation laboratory, leading to a final geologic interpretation. Results obtained by the student will be presented in the format of a series of professional technical reports. Prerequisites: MATH 209, 214, or equivalent, GEOPH 326, PHYS 234 or equivalent. Pre- or corequisite: GEOPH 426 and 436 (field school).Winter Term 2023
