Dr. Abmael da Silva Cardoso

Biographical Information

I was born in Ceres, Brazil, a small town named in honor of the Roman goddess of agriculture. As far as I know, all my ancestors have dedicated their lives to crop and livestock production. When I was a child, I wore my checkered hat and helped my grandfather to manage our family’s cow herd.  Because farming is in my blood, I decided to pursue a high school diploma in agriculture, follow by a bachelor’s degree in agricultural sciences, master in soil science, and PhD in animal science.

My passion for scientific discovery began when I was 14 years old and never stopped since then. In high school, I participated in experiments designed to evaluate the allelopathic effect of African Bermuda grass (Cynodon nlumfuensis) on weeds and N fertilization on wheat production.  During my high school, I also attended my first scientific conference.

During my undergraduate program at Federal Rural University of Rio de Janeiro, I studied nitrous oxide emissions from animal excreta. During my master, I conducted a life cycle analysis assessing the environmental impacts of the 5 main Brazilians beef cattle production systems. During my PhD in Animal Science at São Paulo State University, I evaluated strategies to mitigate greenhouse gas emissions from grazing systems. During this period, I also had the opportunity to work for 1 year as a Visiting Scholar in the Federal Institute of Technology of Zurich, Switzerland where I learned stable isotope techniques (such as 15N) to identify N2O pathways.

After completing my PhD degree, I worked as a Postdoctoral Associate in the Department of Animal Sciences in the São Paulo State University. During this period, I had the opportunity to broaden my scientific skills. My research interests included animal production in grassland, grassland management, and assessing greenhouse gas emissions from dairy and beef cattle production.

In 2019, I met Dr. Silveira during the short course offered to the Unesp Forage Research group in Jaboticabal. In Sept. 2021, I joined her program at the UF/IFAS Range Cattle REC in Ona as an exchange visitor, research scholar for a three year program. I am thrilled to be part of the USDA, Long-Term Agroecosystem Research (LTAR) network mainly because of the multidisciplinary nature of this project and the complex production and ecological challenges it addresses. To me, this is a great opportunity to work collaboratively on science-based solutions that can help advance sustainable intensification of agriculture in the U.S. and globally.
