Introduction

I joined the Dialog State Tracking in Amazon Alexa in April 2019. I completed my Ph.D. in Computer Science at The Center For Language and Speech Processing, Johns Hopkins University. My advisor was Benjamin Van Durme. I TA'd graduate courses on representation learning and machine learning for three semesters during my Phd studies, and I received the George Sommerman Graduate Teaching Assistant Award with a cash award of $1000. I have reviewed for Transactions On Signal Processing-19, NEURIPS-19, ICML-19, ICLR-19, EMNLP-19, ACL-19, TPAMI-18, NeurIPS-18, KG4IR-18, EMNLP-18, ACL-18.
