Born and raised in Rio de Janeiro (Brazil) and now Japan is my home. I am very positive and optimistic in life. I am enthusiastic about learning new topics and interacting with people, especially researchers. When I was a kid, my dream of life was to become a researcher in Japan. I love science, Japan, and exercising outdoor. If there is something that I can help you with, do not hesitate to ask me.

Recent Activities

The planet has suffered a lot due to anthropic actions. Global warming is a worsening reality that needs to be changed quickly. My research focus is the mitigation of nitrous oxide (N2O) that is released from agricultural fields. It is known that this greenhouse gas has a much greater destructive power compared to CO2. Fortunately, studies show that mitigation of N2O is possible achieve by proper management of the microorganisms present in agricultural soils. Therefore, my study is focused on finding natural microorganisms with biotechnological potential that can be used for both N2O mitigation and optimization of agricultural production.
