Short Biography

I am a Ph.D. student at École Polytechnique Fédérale de Lausanne (EPFL) and a research assistant at Idiap. I work under the supervision of Dr. James Henderson in the Natural Language Understanding group. My project is funded by the NCCR Evolving Language, Swiss National Science Foundation Agreement.

My research focuses on discovering meaningful units (i.e., morphemes) from character sequences in an unsupervised manner. We believe that representing text at morpheme-level would lead to better understanding of language in NLP models.

Broadly, I am interested in morphology induction, subword segmentation and unsupervised object discovery methods.
