During my Masters and later on my PhD I researched about intelligent agents, context awareness, natural language processing, machine learning, social networks and middleware. As an outcome of my PhD research, awarded as Best PhD Thesis according to the Brazilian Computer Society in Congress on Computers in Education 2013, a Conversational Intelligent Tutoring System (CITS) that can be used to create personalised virtual learning in Web-based systems was specified and developed. The CITS combines key modules of a traditional conversational ITS with the ability of individual student users to access personalised content via social media (e.g. Facebook, Twitter, Yammer) and heterogeneous Web systems (e.g. Skype, Gtalk, Webmails, LMS and MOOC). My biggest challenge when researching was to create a concept where different systems, devices and data were integrated as an unique distributed learning system.
I am currently a Honorary Fellow/Visiting Academic at Department of Computing and Information Systems and Research Fellow at Melbourne Graduate School of Education, The University of Melbourne.
Parallel to my research, I have worked for 11 years as a Senior System Engineer and Technical Consultant at CESAR (Recife-Pernambuco/Brazil), awarded two times as the most Innovative IT Institute in Brazil, researching/leading/developing for Motorola, Samsung, Compal Electronics and Gemalto international projects. My main responsibilities were to bring innovative solutions to these companies as well as to lead technical cross-disciplinary teams in charge of each project. I have experience in various areas, including: (i) e-learning; (ii) context awareness; (iii) natural language processing; (iv) machine learning; (v) mobile devices; (vi) social networks.
Furthermore, for five years I have been teaching subjects in Computer Science and Digital Games courses in important universities in Pernambuco State, Brazil.
