About
I am interested in
language technologies.
The core algorithms and models used in things
like
machine translation,
virtual assistants
and, more broadly,
information retrieval.
I am a Research Fellow (formerly Chief Scientist) at
ASAPP.
ASAPP is doing
amazing research
in NLP and ML applied to customer service.
I am also an Associate researcher in the
NLP group at
Athens University of Economics and Business. Previously I was
a Research Scientist in the
Language Team at Google for 15 years.
Prior to that I did my Ph.D. in NLP at the University of Pennsylvania supervised by
Fernando Pereira.
