Interests

My research interest is the result of an overlap between natural language processing, data science, artificial intelligence, and machine learning applied to solve different problems.

Here are some research areas I’m currently working on:

  • Natural Language Processing (not extensive)
    • Language modeling
    • Paraphrase generation and detection
    • Text generation and summarization
    • Meeting summarization
  • Large Language Models as Agents
  • Responsible AI
  • Scientometrics and bibliometrics
  • Recommender Systems
  • Machine Learning

Collaborators

Here are some great people (e.g., grad students, researchers, post-docs, practitioners) I have/had the pleasure to work with:
