Being trained as an undergrad Geomechanics Major at Beijing University, I have always been interested in rationalizing the mechanical origins of geologic features I mapped and observed in the field. Towards this end, I have developed several novel analytical and numerical models that deal with the formation of (1) low-angle normal faults, (2) domal and basinal folding of regionally extensive detachment faults during continental extension, (3) formation of monoclinal-fold systems in the interior of a continent driven by far-field plate boundary forces and their interactions with pre-existing weakness, (4) formation of normal faults in compressional thrust wedges, (5) dynamics of ultra-high-pressure metamorphism in subduction zones, and (6) the development of non-Andersonian V-shaped conjugate fault systems. My current work focuses on (1) the mechanics of subduction initiation and sustainability in early planetary evolution and (2) the mechanical origin and transport processes of triangular plutons.

Inspired by simple sand-box experiments that explain the mechanics of non-Andersonian V-shaped conjugate strike-slip faults in my recent research, I spent three years building a sophisticated experimental apparatus at UCLA that is capable of simulating lithospheric deformation under complex interactions of velocity and thermal boundary conditions. The velocity boundary conditions including lateral push and pull, basal shearing and regional tilt can vary with time. Meanwhile, the thermal boundary conditions implemented at the base of the apparatus via thermal couples can vary with time and space. My students and I are currently using this apparatus to address the following questions: (1) interactions between collision-induced shortening in an orogen and lateral flow of mantle from below, (2) interactions of two indenters, and (3) the effect of thermal heating in the late stage of orogenic development. Quantification of the experimental results in terms of velocity and stain-rate fields has been done in collaboration with Prof. Saad Haq at Purdue University.
