Pedro Meirelles is a scientist concerned about the effects of global warming. The biologist turned his attention to aquifers. Their study analyzes microorganisms in these reservoirs to measure the impact of carbon release into the atmosphere. On another front, Pedro Meirelles also investigates the possibility of these microorganisms processing CO2 and mitigating the effects of global warming. Professor at the Institute of Biology at the Federal University of Bahia, Pedro has a master’s and doctorate in genetics from the Federal University of Rio de Janeiro. In addition to trying to stop global warming and enrich knowledge about aquifers, the biologist is also the father of two children.
As we explore the mysteries of nature, a fundamental question arises: how does biodiversity affect ecosystem stability? Several players in this intricate balance may be hidden within Microbial Dark Matter (MDM), a significant fraction of the microbial community yet to be identified or classified. Recent efforts have discovered hundreds of new organisms in MDM that have expanded the tree of life by 15% and are crucial in regulating biogeochemical cycles, such as carbon and nitrogen cycling, essential to the planet’s functioning. In this project, we will investigate MDM diversity and its interactions with the environment. We will dissect the cellular and molecular mechanisms, thus discovering its ecological roles, from the depths of the oceans to our intestines.
The project is designed to explore the impact of climate change on microorganisms and water quality in aquifers, as well as the potential of these microorganisms to mitigate the effects of carbon sequestration. A diverse team of experts will leverage large data sets from public repositories and conduct field and laboratory experiments using state-of-the-art technologies. The application of integrated mathematical and computational models will complement these efforts. This comprehensive approach aims to better understand these complex interactions and their environmental implications.
