I am currently a Data Scientist Researcher at Sacoor Brothers, and I did my Ph.D at the Robotics Institute at CMU as part of the dual degree Carnegie Mellon Portugal PhD program with the Institute for Systems and Robotics at Instituto Superior Técnico, University of Lisbon. My research interestes lie in the application of Machine Learning algorithms for sequence prediction and planning problems with focus on Natural Language Processing and Robotics applications. My PhD advisors were Geoffrey J. Gordon (MLD), Siddhartha Srinivasa (RI) and André F. T. Martins (Unbabel). Prior to graduate school i did my Master studies in Physics Engineering at IST in Portugal.
My research interests lie in general machine learning problems. My prior research work focused on learning methods using semi-supervision. Typically working with large unlabeled datasets and small supervised information. I was also interested in developing algorithms for planning with reinforcement learning.
