I am a catastrophe & risk modeler working within Catastrophe Engineering and Analytics Group of Berkshire Hathaway Specialty Insurance. Prior to that, I completed my Ph.D. research from Computational Mechanics Research Group at University of California, Davis. I obtained my Bachelor's degree from Department of Civil Engineering, Tongji University in 2016. I am currently a member of American Society of Civil Engineers (ASCE), Earthquake Engineering Research Institute (EERI) and American Mathematical Society (AMS).

My research encompasses computational mechanics, engineering seismology, geotechnical engineering and structural dynamics for better safety and economy of infrastructure objects, such as buildings, nuclear installations, dams, etc., against earthquake hazards. These engineering objects under seismic excitations can be generalized as Earthquake Soil Structure Fluid Interaction (ESSFI) system. Focus is on improving state of the art probabilistic seismic hazard/risk analysis of ESSFI system, including: (1) Characterization/propagation of aleatory variability; (2) Quantification/reduction of modeling epistemic uncertainty. Emphasis is to develop theoretical methodology and high performance simulation system that predict and inform rather than fit. Current work include:
Characterization & propagation of aleatory variability
Quantification & reduction of modeling epistemic uncertainty
Most of my research contributes to Real-ESSI Simulator System, a high fidelity finite element simulator for static and dynamic, deterministic and probabilistic, elastic and inelastic modeling and simulation of earthquakes, soil, structures and their interaction.
