Here To Help

I'm a research scientist at the JHU HLTCOE interested in natural language processing and machine learning. I also have an appointment in the Department of Computer Science and work closely with PhD students and faculty at the Center for Language and Speech Processing.

PhD students: David Mueller (co-advised by Mark) and Aleem Khan (co-advised by Ben).

About me: I obtained my PhD from JHU in 2015, advised by Jason Eisner and Mark Dredze. Before that, I worked at BBN Technologies. Fun facts: I grew up in England and Switzerland, speak French, and I'm an avid cyclist.

News / Highlights

  • [Funded summer opportunity] I am leading the 2022 SCALE summer workshop on authorship analysis! If you are a researcher or student interested in modeling writing style, deep metric learning, uncertainty estimation, graph embeddings, or explainability for text models, please contact me. (Virtual participation will be possible.)
  • Paper on universal author embeddings with Aleem, Marcus, and colleages at Lawrence Livermore National Labs accepted to EMNLP 2021!
  • Paper with Aleem, Noah, Elizabeth, and Marcus accepted to NAACL 2021!
  • Paper with Steven and David accepted to EMNLP 2020!
  • Led the SCALE 2019 workshop on NER. With over 50 participants, this was the largest SCALE to date. Thanks everyone, especially the students!
