Computer Science and Engineering

*** I am currently recruiting PhD students to work on topics such as social and cognitive robotics, reinforcement learning, interactive machine learning, explainability, and multi-agent systems. If you are interested or would like to discuss further details, please get in touch or check my personal webpage (https://www.franciscocruz.org). ***

I received a bachelor’s degree in engineering and a master’s degree in computer engineering from the University of Santiago, Chile, in 2004 and 2006, respectively, and a Ph.D. degree from the University of Hamburg, Germany, in 2017, working in developmental robotics focused on interactive reinforcement learning.

In 2015, I was a Visiting Researcher within the Emergent Robotics Laboratory, Osaka University and in 2018, a Visiting Researcher within the Polytechnic School, University of Pernambuco, Brazil. I joined UNSW in 2022 as a Lecturer in Cognitive Robotics. My current research interests include reinforcement learning, explainable artificial intelligence, human-robot interaction, artificial neural networks, and psychologically and bio-inspired models.
