About me

I am currently a Research Scientist at HLTCOE@JHU working on cross language and multilingual information retrieval and multilingual, multimodal report generation, which is an information-intense retrieval-augmented generation task. I recieved Ph.D. in Computer Science from Georgetown University in 2021, under the advice of Ophir Frieder in the IR Lab, David D. Lewis at Redgrave Data and Jeremy Fineman.

My research interests are ad-hoc retrieval, retrieval-augmented generation and high recall retrieval

I am also the developer of TARexp, which is an opensource Python experiment framework for Technology-Assisted Review.

我在 HLTCOE@JHU 擔任研究員,主要的研究多語言搜尋引擎及多語言多模態報告生成。 2021 年的暑假畢業於 Georgetown University 並得到資訊工程博士學位, 指導老師為 Ophir Frieder (IR Lab) 、David D. Lewis (Redgrave Data) 及 Jeremy Fineman

我主要的研究興趣包含跨語言搜尋引擎、檢索增強生成及高召回搜尋。

我開發了 TARexp。 這是一個特別為 Technology-Assisted Review 而開發的 Python 實驗平台。
