Research Scientist, Data Scientist, and Master Inventor


IBM Research - Brazil São Paulo, Brazil


Research Scientist, Certified Data Scientist, and Master Inventor at IBM Research. PhD and MSc degrees in Computer Science from University of Campinas (UNICAMP), 2012 and 2009, respectively. BSc degree in Computer Science from Presbyterian University Mackenzie (2006). I am passionate for interaction logs, researching about how people interact with information technologies, in real contexts of use, at scale.

I have been developing software professionally since 2000 and, prior to engaging in research activities, I was webmaster at Folha de S.Paulo (, a major Brazilian newspaper, from 2001 to 2007.

I have been researching topics on Human-Computer Interaction (HCI) since 2006, focusing on interconnections among HCI, Machine Learning, and Data Science, ranging from problem understanding & field studies to data-oriented evaluation & delivery of intelligent user interfaces.

Since 2016, I am associated collaborator at Federal University of ABC (UFABC), where I supervise MSc and PhD students. Prior to this experience in supervising graduate students, I acted as visiting professor in multiple Software Engineering disciplines in graduate courses at Presbyterian University Mackenzie (from 2009 to 2015) and at PUCRS (2021).

I have been actively collaborating with Brazilian and International HCI communities. In Brazil, I was general chair of XV Brazilian Symposium on Human Factors in Computer Systems (IHC 2016), the main HCI conference in Latin America. In 2019, I was lead program chair of IHC 2019 conference. Moreover, I actively act as reviewer for multiple international HCI conferences and journals (e.g., IJHCS, UAIS, TACCESS, Multimedia Tools and Applications, and Interacting with Computers).

In 2012, I joined IBM Research just after completing my Ph.D. degree. At IBM Research I participated in multiple projects from different industries as IT services, Finance, Health Insurance, Education, Oil&Gas, and Agriculture. In 2016 I became Master Inventor, in 2019 I obtained my Data Scientist certification, and in the last years I have been continuously mentoring researchers on Intellectual Property (IP) process and acting as IP review board member for IBM patents as well.
