I am a Research Scientist at Google Research in Tel-Aviv where I work on natural language processing. Before that I was fortunate to complete my Phd at BIU's NLP lab under the supervision of Prof. Yoav Goldberg. My master's thesis was carried under the supervision of Prof. Moshe Koppel. My main interests are at the intersection of machine learning and natural language processing, with a soft spot for machine translation and other text generation tasks. When not working on NLP you can usually find me on the mat (practicing or teaching Ashtanga Vinyasa Yoga) or underwater.
