I am a 2nd-year PhD student in NLP at the Language Technology Lab, University of Cambridge, supervised by Professor Nigel Collier. I recently am working on three things:
   1. multi-modality: connecting language with knowledge and perception;
   2. self-supervision: specialising language models without (human) labels;
   3. interpretability: what’s encoded/missing in (pre-)trained model weights?
I am a member of Clare Hall and a Trust Scholar funded by Grace & Thomas C.H. Chan Cambridge Scholarship. Besides Cambridge, I also spend(t) time doing research at Amazon, EPFL, and Waterloo.


  • [Oct 29th, 2021] MaRVL won the Best Long Paper Award at EMNLP 2021! Congrats to my dear collaborators: Emanuele Bugliarello (co-lead), Edoardo Maria Ponti, Siva Reddy, Nigel Collier, Desmond Elliott.
  • [Sep 28th, 2021] Releasing Trans-Encoder: unsupervised knowledge distillation from a pretrained language model to itself, by alternating between its bi- and cross-encoder forms.
  • [Aug 27th, 2021] Four papers accepted to the main conference of EMNLP 2021. See you in Punta Cana (hopefully?).
  • [Aug 27th, 2021] SapBERT is integrated into NVIDIA’s deep learning toolkit NeMo as its entity linking module (thank you NVIDIA!). They even wrote a tutorial – check out this Google Colab.
  • [May 6th, 2021] A cross-lingual extension of SapBERT will appear at ACL-IJCNLP 2021.
  • [April 16th, 2021] Happy to have given a talk about SapBERT (our recent NAACL paper) at AstraZeneca’s NLP seminar. Here are the slides.
  • [April 15th, 2021] We released Mirror-BERT, a fast, effective, and self-supervised approach for transforming masked language models to universal language encoders.
