About me

I am a Senior Data Scientist at Morningstar, Inc.

I currently work on developing a suite of tools for data extraction and information acquisition using Natural Language Processing, Pattern Recognition, and Generative AI.

I have 10+ years of experience as a researcher in data science and complex systems. I have experience in Machine Learning, Deep Learning, Bayesian Statistics, and Network Science and 24 peer-reviewed scientific publications that have amassed 900+ citations. I have mentored 10+ students in data science and complex network research.

Previously, I worked as a Data Scientist at Northwestern Institute of Complex Systems and as a Postdoctoral Fellow in the Amaral-Lab at Northwestern University. I was a Postdoctoral Fellow at the Institute of Mathematics and Computer Science at the University of São Paulo.

I have a bachelor’s degree in Physics (2012), a master’s degree in Physics (2014), and a Ph.D. degree in Physics (2017) from the State University of Maringá.

Experience

 
 
 
 
 
Senior Data Scientist
Jan 2023 – Present Chicago, IL - USA
My work revolves around developing cutting-edge tools for data extraction and information acquisition leveraging Deep Learning, Natural Language Processing, Pattern Recognition, and Generative AI.
 
 
 
 
 
Data Scientist
Oct 2022 – Jan 2023 Evanston, IL - USA
I worked on developing a suite of tools to enable access to court records and analytics. I designed, developed, and deployed machine/deep learning models for entity resolution, named entity recognition, and text classification.
 
 
 
 
 
Postdoctoral Fellow
Nov 2018 – Oct 2022 Evanston, IL - USA
I designed and developed research projects in complex systems and data science. These projects included predicting link removals in transportation networks, studying the spread of innovation in networks of specialists, and modeling crime in US cities. I was also an instructor for NICO101/NICO401 - Introduction to Programming for Big Data (Fall 2021 and Fall 2022).
 
 
 
 
 
Postdoctoral Fellow
Apr 2017 – Oct 2018 São Carlos, SP - Brazil
I led a project on a complex systems approach for urban planning and development. I investigated changes in trade networks during financial crises and developed a model to detect anomalies in complex networks. I also modeled the complex network of politicians investigated in corruption scandals.
 
 
 
 
 
Visiting Scholar
Nov 2015 – Oct 2016 Evanston, IL - USA
I worked with an interdisciplinary team of biologists and computer scientists to develop computer vision software capable of recording the trajectories of various worms in a Petri dish. We collected data and investigated the behavior of C. elegans as they age and how they behave under stress.
 
 
 
 
 
Research Assistant
Mar 2013 – Mar 2017 Maringá, PR - Brazil
I collaborated on many projects on complex social systems and statistical physics using data science techniques and statistical physics tools. These projects included the analysis of urban systems, crime in urban areas, and diffusion of particles and microorganisms. I also worked modeling Earthquakes and lightning activities.

NICO101/NICO401 - Introduction to Programming for Big Data:

 
 
 
 
 
Invited Lecturer
Jul 1, 2019 – Jul 6, 2019 University São Paulo - Institute of Mathematics and Computer Science, São Carlos, SP - Brazil

School of Applied Mathematics - Crime and political corruption analysis using data mining, machine learning and complex networks:

  • Program: The accumulation of large amounts of data by private or public initiatives is increasingly common. On the one hand, these data allow a detailed historical review of the process in question; on the other, information overload makes it very difficult to extract summary information and make decisions supported by empirical facts. This modern phenomenon has been called big data and understanding these systems and extracting patterns from these data requires a multidisciplinary approach. During this course at the School of Applied Mathematics at ICMC, we address topics involving computer science, statistics, and physics. Among them, we focus on the following topics:



    • Introduction to python, scraping and data mining;
    • Machine learning;
    • Complex networks.

    Using these tools, we will focus on two issues that are of great relevance in Brazil: the prediction of homicides in cities and the description of the mechanism behind political corruption networks. In the first theme, we will use machine learning techniques to predict the number of crimes in Brazilian cities. In the second theme, we will use complex networks to describe the interaction between politicians investigated in corruption scandals in Brazil from 1987 to 2014.
