Terry Ruas has completed his Ph.D. in Computer and Information Science at the University of Michigan – Dearborn in the USA, where he also worked as Graduate Student Instructor for graduate and undergraduate courses. He completed his MSc and BSc in Information Engineering and Computer Science respectively at the Federal University of ABC (UFABC) in Brazil. During his graduate studies, he also worked in the industry for IBM for five years. He was also a Ph.D. intern at the National Institute of Informatics in Tokyo, Japan and a summer teaching assistant at VelTech in Chennai, India.


Terry’s research interest is the result of an overlap between natural language processing, data science, and machine learning applied to text mining to extract semantic features. He explores how semantic features can be used to solve different NLP downstream tasks and real-world problems. More specifically, he is interested in how to improve scientific paper mining and recommendation using semantics. Terry’s primary research interest topics are:

  • Natural language processing
  • Machine learning
  • Scientific paper mining
  • Scientometrics
  • Data Science
