Summary. I create natural language processing systems using state-of-the-art machine learning algorithms, such as deep learning. Such systems process large amounts of textual data, on the order of millions or tens of millions of documents, from sources such as Facebook, Twitter, and news feeds. The goal is to extract useful insights from these data, such as:
- categorizing documents (e.g, Facebook posts, tweets),
- extracting semantically relevant information,
- performing sentiment analysis,
- automating Facebook targeting,
- providing rich, semantically informed summaries of document collections (e.g. what are people talking about and how do they feel about it).
Shortened summary. I work on the following problems: given the vast amounts of data available on the web, how can we use massively scalable, parallel algorithms such as deep learning to answer questions about what people are talking about, what their sentiments about those topics are, and what new and relevant information we can provide to them.
Shorter summary. Artificial Intelligence/machine learning researcher with expertise in automated natural language processing. Extensive experience in designing adaptive, language-using applications and in directing research projects that study how humans and automated systems learn and use language.
