My research aims at enabling ubiquitous long-form text generation, where anyone can produce a document on any topic with just a few clicks. To achieve this goal, my research focuses on the following three directions, utilizing advances in deep learning combined with probabilistic modeling:

• Long-Form Coherence to generate coherent documents with self-consistency and clear transitions.
• Transparent Generation to enable users to understand, debug, and control document generation.
• Efficient Systems to handle the scale and real-time requirements of long-form text generation.

I also work on open-source projects such as OpenNMT, Im2LaTeX, LaTeX2Im, and Steganography to make my research efforts more readily available for developers and researchers.
