毕业于加拿大阿尔伯塔大学(2013-2018)，博士后就任于加拿大韦仕敦大学，主要研究方向有：诱发地震，地震监测及定位，震源机制，统计地震学。研究成果发表于Geophysical Research Letter (3篇)， Journal of Geophysics: Solid Earth (2018年最高引文章之一)等期刊。博士期间获得Canadian Geophysical Union (CGU, Solid Earth), American Geophysical Union (AGU), Seismological Society of American (SSA, East Section), 以及 Society of Exploration Geophysics (SEG)多项国际会议最佳口头报告奖。近年来参与担任AGU 和SSA诱发地震方向会议主持。即任于新墨西哥大学博士后，研究方向为火山地震学。
Seismicity rate in the Western Canada Sedimentary Basin (WCSB) has increased substantially in the past 5 years, mainly due to local hydraulic fracturing (HF) operations for shale gas exploration. Aside from consistent shallow (<5 km, above the basement) hypocenters, it has been suggested that the focal mechanisms of these earthquakes exhibit strong non-double-couple (non-dc) component similar to microseismic events. in this paper, we systematically analyze the source parameters and fault characteristics of intermediate (m~4) earthquakes in the wcsb. the resulting focal mechanisms show either major strike-slip (in central alberta) or thrust (e.g., along the canadian rockies) faulting mechanisms. we validate the induced nature of the newest seismic cluster (january 2016, crooked lake) via the spatial-temporal relationship between the seismic swarm and injections at a nearby hf well. in addition to characterizing the fault geometry, we also examined the statistic properties of both induced and natural earthquakes in this region.
