Robson L. F. Cordeiro received the BSc degree in Computer Science (CS) from the University of Oeste Paulista, Brazil, in 2002, the MSc degree in CS from the Federal University of Rio Grande do Sul, Brazil, in 2005, and the PhD degree in CS from the University of São Paulo, Brazil, in 2011. His PhD program included a visiting period of one year at the Carnegie Mellon University, USA, from 2009 to 2010. He also holds Postdoctorate degrees in Computer Science and Computational Mathematics (2013), and in Development of Complex Data Managers (2021), both obtained at the University of São Paulo, Brazil. His PhD Dissertation won the ?best CS Dissertation Award? in 2012 from the Brazilian Computer Society - SBC, and generated one book published by Springer that was chosen as one of the 'Computing Reviews' Notable Computing Books and Articles of 2013' by ACM. Robson is currently an Associate Professor at the University of São Paulo, Brazil. His research interests include mining and managing Big Data of moderate-to-high dimensionality, complex data and large graphs. He is a member of the IEEE, ACM, SIAM and SBC.

In a data stream with many attributes and a high frequency of events, how to spot clusters of similar events? How to identify outlying events, and sort them according to how much they differ from the main data patterns? Can it be performed in real time? For example, based on the actions of users over time in an online digital game management system, how to identify clusters of users/playe…
In the Relational Algebra, the operator of Division (÷) is an intuitive tool to write queries involving the concept of "for all", and thus, it is constantly required in many real applications. However, we demonstrate here that the relational division cannot support many of the needs common to current applications, particularly, those that involve complex data analysis, such as processing …
The ENEM - National Secondary Education Examination - is a test that seeks to assess the performance and quality of teaching in Brazilian territory. Not only that, since 2004 the exam has also been used as a way of evaluating candidates that apply to courses of higher education. Considered the biggest test in the country, the program revolutionized the education market. Currently, most sc…
Given the stock prices for many companies in financial markets over the time, how to spot start-ups behaving similarly to the initial development stage of consolidated companies, so to support the forecast of future behaviour? Is it possible to use similarity joins to help tackling the problem? The similarity join operation is one of the main tools used to support the analysis, understand…
The relational Algebra division operator allows the representation of simple queries with the concept for everyone, and so it is constantly required for real applications. However, it is evident in this research project that the division does not meet the requirements of many current applications, especially when analyzing complex data such as images, audio, texts, fingerprinting, large g…
Since its establishment, the Intergovernmental Panel on Climate Change has been reporting that, probably due to human intervention, the average temperature on earth has been continually raising at least for the last hundred years. The ten warmest years registered in history are within the last twenty years! 2010 is tied with 2005 as the warmest year on record. Climate changes forecast all…
