About me

I am currently a Research Associate at HLTCOE@JHU working on cross language information retrieval. 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.
I also consult for the Applied Science Team at Relativity, a leading software company in eDiscovery, on active learning, search systems, and result validation.

My research interests are ad-hoc and high recall information retrieval, active learning, and low-resouce machine learning.

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

我目前是 HLTCOE@JHU 的博士後研究員,主要的研究跨語言搜尋引擎。 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。
我同時是 Relativity 的顧問應用科學家,主要指導主動學習、搜尋引擎及結果認證方法的實務建議及實作方針。 Relativity 提供領先業界 eDiscovery 工具的軟體公司。

我主要的研究興趣包含搜尋引擎、高召回搜尋、主動學習、以及資源限縮的機器學習問題。

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