Sr. Research Associate, Department of Global Development
Adjunct Associate Professor, School of Integrative Plant Science Plant Pathology and Plant-Microbe Biology Section
Dr. Maricelis Acevedo is the Associate Director for Science of the Delivering Genetic Gain in Wheat project in the Department of Global Development at Cornell University. She works side by side with wheat scientists (breeders, geneticists and plant pathologists) around the world to develop and deliver wheat varieties that are high-yielding and disease-resistant. She also contributes to the wheat breeding and pathology capacities of the National Agriculture Research Programs in Ethiopia, Kenya, and South Asia by providing guidance and support for research infrastructure and providing training opportunities for junior scientists. As a member of the Borlaug Global Rust Initiative (BGRI), she is part of a global interdisciplinary network of wheat scientists committed to food security through advances in agriculture and capacity building.
In 2020 Dr. Acevedo became the Director for USAID Feed the Future Bangladesh Bt-Eggplant project ($4.6M). Bt-eggplant adoption in Bangladesh has significantly reduced the need to utilize insecticide in farmers’ fields while increasing crop yields.
In 2018, Maricelis was appointed Adjunct Associate Professor in the Plant Pathology and Plant-Microbe Biology (PPPMB) Section of the School of Integrative Plant Science within CALS and International Professor of Plant Pathology and Plant-Microbe Biology in CALS. As an International Professor in the Field of Plant Pathology, Maricelis serves on Cornell’s PPPMB and Plant Breeding and Genetics graduate students’ thesis committees.
Prior to joining Cornell, Maricelis was the cereal rust pathologist and assistant professor in the Plant Pathology Department at North Dakota State University in Fargo, ND. During her time at NDSU, she taught a graduate course on Population Biology of Plant Pathogens and mentored four Ph.D. students and three master’s students. She has published numerous original research scientific manuscripts in peer-reviewed journals, one book chapter, and many outreach and extension manuscripts.
Her formal education includes a BS in Biology and MSc in Crop Improvement from the University of Puerto Rico, Mayaguez Campus. She earned a PhD (2007) in Biology with a specialization in Plant Pathology from the University of Nebraska, Lincoln. She was a post-doctoral fellow at the USDA-ARS Potato and Small Grains research Unit in Aberdeen, Idaho. In 2010 she was among the first recipients of the Jeanie Laube Borlaug Women in Triticum Early Career Award.
Maricelis is originally from Puerto Rico, where her parents live on a small farm in the town of San Sebastian, on the north west side of the Island.
