Work Experience

Computer Vision Researcher at FEA/UNICAMP

February 1, 2023 - February 1, 2024

As part of a research project, I developed an algorithm for detection, counting, and classification of yeast cells and yeast colonies in microscopic and panoramic images. The solution was implemented in Python using computer vision techniques and employs mathematical and image processing methods such as the Hough Transform and Morphology to accurately identify and segment cells and colonies. Publication featured on Oxford Academic.

Machine Learning Researcher at NIED Unicamp

February 1, 2024 - October 1, 2025

Developed an automated academic article classification system for a research project using linear and nonlinear SVM, MLP models, and large language models (LLMs). Participated in the full model development pipeline—from preprocessing and structuring raw, unstandardized data to model training and evaluation. Achieved a 94% F1-score with reduced-model approaches.
