# Tara Sainath

## Biography

I received my PhD in Electrical Engineering and Computer Science from MIT in 2009. The main focus of my PhD work was in acoustic modeling for noise robust speech recognition. After my PhD, I spent 5 years at the Speech and Language Algorithms group at IBM T.J. Watson Research Center, before joining Google Research. I have served as a Program Chair for ICLR in 2017 and 2018. Also, I have co-organized numerous special sessions and workshops, including Interspeech 2010, ICML 2013, Interspeech 2016 and ICML 2017. In addition, I am a member of the IEEE Speech and Language Processing Technical Committee (SLTC) as well as the Associate Editor for IEEE/ACM Transactions on Audio, Speech, and Language Processing. My research interests are mainly in acoustic modeling, including deep neural networks, sparse representations and adaptation methods.
