I'm a Senior Research Scientist at the JHU HLTCOE and an Assistant Research Scientist in the Department of Computer Science. I also work with PhD students and faculty at the Center for Language and Speech Processing.

PhD students:
    David Mueller (co-advised by Mark Dredze)
    Aleem Khan (co-advised by Benjamin Van Durme)
    Sophia Hager (co-advised by Kevin Duh)
    Rafael Rivera-Soto
    Andrew Wang (co-advised by Daniel Khashabi)

Postdocs:
    Cristina Aggazzotti
    Zexin Cai (co-advised with Matthew Wiesner)

Hiring: I am actively recruiting postdoctoral fellows interested in generation, particularly in the areas of speech synthesis and detection of synthesized speech. Please feel free to contact me directly if you are interested! For PhD programs, please refer to this link for detailed instructions on how to apply.
