Biologist Leandro Santos is at the forefront of biomass-derived fuel production in Brazil. He was the first in the country to develop a genetically modified yeast that leverages its metabolism to produce bioethanol. This yeast is currently being utilized in the industry. Leandro earned his master’s degree in agricultural microbiology from the Federal University of Viçosa and his PhD in genetics and molecular biology from the State University of Campinas. To unwind, he dons the chef’s hat and prepares weekend lunches for his household. Additionally, tending to the family farm provides him with the tranquility needed to continue his work.
