我的專長為觀測地震學及斷層活動監測。近年來的研究主軸在偵測分析各種特殊的地震訊號及其活動特徵，以探索斷層帶構造和地震行為之間的關係。
 

過去二十年，我的研究團隊以台灣活躍的碰撞造山帶為天然實驗室，發展適合台灣地震資料特性的偵測與分析方法，長期追蹤重複地震（repeating earthquakes）、地震群（earthquake swarms）與構造微震（tectonic tremors）。這些看似不同的地震現象，其實提供了觀察無震變形(aseismic deformation) 的不同窗口：重複地震可以量測深部斷層潛移與滑移速率，地震群反映暫態無震變形，而深部構造微震則讓我們得以觀察一般地震活動帶以下、下部地殼中的緩慢變形。透過這些互補觀測，我們逐漸建立起從淺部孕震帶延伸至約 40 公里深處的變形活動圖像。

​

其中，我們特別關注潛移斷層並不等同於「安全的斷層」。利用重複地震作為天然的深部潛移計，我們除了研究著名的池上斷層，也辨識出台灣過去未被充分認知的深部快速無震滑移區-位於中央山脈北段約20 km深處。並進一步將重複地震推估的滑移速率與 GPS、InSAR 等大地測量資料結合，以解析斷層上潛移與鎖定區之空間分布。這些研究顯示，即使快速潛移的斷層，仍可能存在能夠孕育中大型地震。

​

另一條研究主軸則深入碰撞造山帶下方的無震變形。我們在台灣中央山脈下方發現大量長微震（慢地震的一種型態），顯示在一般地震活動帶之下仍存在活躍的緩慢剪切變形。這些微弱訊號對數kPa甚至更小的應力擾動極為敏感，也受到流體、溫度與深部構造條件控制，使構造微震成為探測下部地殼力學狀態的重要工具。

​A major challenge in earthquake science is that much of fault deformation occurs aseismically and therefore remains invisible to conventional earthquake observations. My research over the past two decades has focused on making this hidden deformation observable and using it to understand how active faults evolve through the earthquake cycle. Taiwan provides an exceptional setting for this effort: rapid continental collision produces intense crustal deformation, while dense seismic and geodetic observations provide an unusually rich record of fault activity. My contribution has been to develop methods that extract new physical information from these resources and to integrate complementary observations across depths and timescales.
