Researcher (Jul. 2020 - Mar. 2024:)

  • I started as a researcher on a project to develop a COVID-19 contact notification app. I conducted project planning and identified reliable government and public data sources. I analyzed geolocation data to create interactive risk maps, estimating exposure risk based on location, symptom severity, and crowd density. However, the project was discontinued.

Following my contributions to the project, I was reassigned to a credit risk analysis initiative for the energy sector, which later led to the founding of Risk3, a startup specializing in credit and risk analysis. I played a key role in developing the entire system (software and web app) and building mathematical and statistical models for counterpart risk assessment.

In parallel, I worked on R&D projects, contributed to product development, and provided technical support. I bridged the gap between technical and non-technical teams by explaining the complexities of software and analytical models to clients and stakeholders.

(UNICAMP) Universidade Estadual de Campinas

FEEC - Faculdade de Engenharia Elétrica e de Computação

Research Assistant (Ago. 2015 - Jun. 2020:)

  • I worked on mathematical modeling, pattern recognition, optimization, and simulation, focusing on the spread of Huanglongbing (HLB), a devastating citrus disease with no cure. My research involved studying reaction-diffusion systems to analyze dispersion patterns and developing an Individual-Based Model (IBM) to simulate the spatial spread of psyllid vectors. I investigated how inoculum dispersion impacts crop yield, considering disease severity and plant age.

As part of this work, I secured international funding for a research collaboration at TU Dresden, Germany. I also presented my findings at EncBioMat – 3rd Biomathematics Meeting (UNICAMP, IMECC) with the talk “Análise do padrão de dispersão da doença dos citros (HLB) e de seu vetor.”

In 2020, I attended the School on Community Ecology: From Patterns to Principles at ICTP – UNESP São Paulo, where I explored advanced topics in ecological dynamics and mathematical tools for macroecological patterns. I delivered the talk “Vector-borne diseases: A mathematical and computational perspective.”

  • Participated in an international research collaboration at TU Dresden, Germany, funded by the European program EBW+. This experience significantly enhanced my autonomy and professional skills, as well as providing interaction and understanding of different cultures, including my own. During this period, I learned German (A2 level) and expanded my technical expertise in mathematical modeling and spatial analysis. My work focused on:
    • Developing and programming models, as well as conducting and analyzing simulation experiments using Individual-Based Modeling (IBM) / Agent-Based Modeling (ABM), using R and NetLogo.
    • Generating, processing, and analyzing geo-data for integration into IBM/ABM models.
    • Model development, implementation, parameterization, and sensitivity analysis.
    • Handling uncertainties in data, designing simulation experiments, and conducting statistical analyses.
    • Integrating spatial data into models using Geographic Information Systems (GIS), including geo-data processing, visualization, and elementary analyses. My research, “Spatial dispersal patterns of citrus disease (HLB) and its vector,” was accepted for presentation at the ECMTB 2018 Conference in Lisbon, Portugal, in 2018.
      Additionally, I attended the 11th Annual Summer School in Individual/Agent-Based Modeling, where the instructors were Uta Berger (TU Dresden, Germany), Volker Grimm (UFZ, Germany), and Steve Railsback (HSU, USA), renowned experts in the field.
