I am a postdoc researcher in the
Language and Interaction Research (LAIR) Lab at MSU. I also
collaborate with UCLA's
Center for Vision, Cognition, Learning, and Autonomy (VCLA) .
My Linkedin page.
I am broadly interested in natural language
processing, human-machine interaction/dialogue and educational uses of
technologies. Two dreams have motivated my interests:
Electronic devices can be easily used by people like my parents (actually, by everyone), in a natural way;
Everyone, especially those in
regions lacking educational resources, can have the equal
opportunity of being well-educated.
My current research focuses on situated human-robot dialogue
(demos: 1, 2).
It provides me a good field to learn how to develop robust and adaptive
dialogue systems in the real world.

Deep Learning: online textbook, online course
(Python and NLTK are really handy)
list of NLP conferences
In my spare time, I like reading, traveling, and swimming.
I am also a fan of Tai Chi (太极). Check out
Jet Li's website
