Research on the theme: "Quimicanimada: Production of Animations to Aid the Teaching of Chemistry in High School."Quimicanimada is dedicated to creating 3D animations of chemical experiments using Blender, with a focus on enhancing the understanding of submicroscopic, macroscopic, and symbolic Chemistry concepts—areas often challenging to visualize in traditional labs. These animations, along with explanatory texts, exercises, and project information, are made publicly accessible to support students lacking access to physical laboratories. I was responsible for the conception, design, and development of the website and REST API. This project was developed under the Institutional Scholarship Program for High School Scientific Initiation (PIBIC-EM), funded by the National Council for Scientific and Technological Development (CNPq) at the State University of Campinas (Unicamp), and was presented at the 2022 International Congress "Teachers Movement" and the 30th State University of Campinas Scientific Initiation Congress.

Research on the theme: "Aquarium Automation for Captive Breeding of 'Betta splendens'."This project explores the automation, monitoring, and remote control of aquariums to advance the study of 'Betta spp.' reproduction, employing microcontrollers like Arduino Uno and ESP32, coupled with programming tools such as Node.js and MicroPython. The front-end web application, developed using React.js, enhances user interaction through Next.js and WebSocket communication. I led the R&D for this project, which was also part of the Institutional Scholarship Program for High School Scientific Initiation (PIBIC-EM), funded by the National Council for Scientific and Technological Development (CNPq) at the State University of Campinas (Unicamp). It was presented at the 31st State University of Campinas Scientific Initiation Congress, the 20th Latin American Congress of Marine Sciences, and the 8th Brazilian Congress of Marine Sciences.
