Profile Summary

I am a Food Scientist with a PhD in Food Science (University of São Paulo – USP), a Master’s degree in Biochemistry, and a Bachelor’s degree in Food Science and Technology (UNIPAMPA). I have over eight years of experience combining scientific research, laboratory management, and quality systems within the food industry. My background includes conducting research on bioactive compounds with anticancer potential, lipid biotechnology, molecular mechanisms, and toxicity assessment using different in vitro and in vivo models. I have developed experimental methodologies, performed biochemical and molecular analyses, prepared technical reports and scientific articles, and submitted protocols to the Animal Ethics Committee. In the industry, I have worked as a Quality Supervisor in frozen bread and pasta manufacturing, and as a Laboratory Coordinator and Quality Control Leader in dairy production, focusing on Good Manufacturing Practices (GMP), Good Laboratory Practices (GLP), Standard Operating Procedures (SOPs), HACCP systems, traceability, and regulatory compliance. I also work as a Technical Food Consultant, supporting producers, foodservice operations, and industries in product formulation, labeling, and compliance with sanitary and environmental regulations. Passionate about science and innovation, I combine academic rigor with industrial experience to deliver practical, evidence-based solutions for product optimization, food safety, and regulatory compliance.
