<h4>About Me</h4>
<p>
Welcome to my professional Website!. <br /> </p>
<p>
I am a Postdoctoral Research at Institute of Computing, University of Campinas/BR. Also, I'm research collaborator with the Center for Complex Networks and Systems Research (CNetS), Indiana University, Bloomington/USA, and have some collaborative research at the National Institute for Space Research - INPE/BR. <br> <br />
My research activities are in Artificial Intelligence with complex networks, social networks analysis, data mining and information spreading models applied to big data. Currently, my fields of interests encompass machine learning based on graphs, modeling climate systems and disasters risk reduction and management.
If you need further information or are interested in collaborations, please don't hesitate to contact me.

<p>
In this project, we aim to develop methods to improve the tasks of machine learning based on graphs (networks), analyzing the impact the network structure has on the tasks. Also, through the use of multilayer networks, we will develop new methods for graph-based machine learning. The analyzes will be conducted considering the theory of complex networks and machine learning, using artificial and real databases, evaluating with literature methods and applying to real problems

<p>
In this project, we aim to develop methods to analyze the patterns of activity and the evolution of spatiotemporal systems with dynamic networks. The project includes the design, development, and testing of new techniques for mining temporal and dynamic networks and the application of network analysis techniques to real-world problems.

<p>
I am a research collaborator in this project, which seeks to continue the German-Brazilian cooperation initiative currently underway, aims to study the principles and foundations of self-organization in more general complex networks, where the topology is not simple and complexity is very elaborate. Aiming at applications in current situations of interest, it is intended to understand the role that structure heterogeneity, delays in multiple time and space scales, and stochasticity have on the network dynamics

<p>
I am a research collaborator in this project, which investigates in depth all the steps involved in SSL, including the selection of initial labels, the selection of the network to be built and the method for propagating labels, and propose new approaches to improve this process. Challenges of the area will also be addressed such as contaminated or unbalanced labels, large databases and applications in text mining, climate data analysis and data augmentation for images
