The important thing is not to stop questioning. Curiosity has its own reason for existing. (Einstein, A.)

I’m an MSc student in Computer Science at PUC-Rio, advised by Prof. Hélio Côrtes Vieira Lopes. Currently, I work as a AI Researcher at Holistic AI (London, UK) and a Research Engineer at Exacta (PUC-Rio). I am also a contributor to Understanding Artificial Intelligence (UAI) (UAI, IEA-USP).

My research interests include (and is not limited to):

  • Graph Representation Learning
  • Trustworthy AI
  • Algorithms for Optimization
  • Machine Learning Methods
  • Machine Learning Systems

The best way to contact me is by email: kleyton.vsc@gmail.com. I’m always open to interesting discussions and collaboration opportunities. It’s possible check my research on Google Scholar.
