Marcelo Wallau

Marcelo Wallau recently rejoined the Agronomy Department at the University of Florida as a Forage Extension Specialist (70% extension, 30% research). With an engineer and MS degree in Agronomy and PhD in Animal Sciences, his focus is on forage production and management for beef cattle, dairy cattle and horses, and on integrated crop-livestock systems. Coming from a farming background in southern Brazil, Dr. Wallau’s interests are on the big picture of the production systems, searching for solutions for daily questions from our farmers with a deep scientific base and global perspective. He also has worked on grassland ecology, modeling and foraging behavior, and on feral hog management and control. You can view his Research Gate Profile here. His CV is available here.

Marcelo Osorio Wallau is from Santana do Livramento, Rio Grande do Sul, Brazil. He grew up his family ranch close to the border with Uruguay, raising sheep, horses, beef and dairy cattle, all in pasture-based systems. From early childhood, he learned the principles of cowboying, range management, and respect for the nature and for the elders. From his close contact with livestock and grazing, he developed a deep interest on pasture production. He moved out of his hometown in 2004, heading to Porto Alegre after period in Finland for high school. In 2006, Marcelo started his undergraduate degree in the Agronomy Department at the Universidade Federal do Rio Grande do Sul. As scientific initiation, Marcelo worked for three years at the Soil Microbiology Laboratory, under the supervision of Dr. Enilson Sá. During his undergraduate career, he took internships in south and central Brazil, and in Argentina. In 2009, he went to Texas Tech University in Lubbock, TX as an exchange student for one year, where he studied and worked in Dr. Vivien Allen’s forage lab.

Marcelo graduated as an agronomy engineer in August 2011 and shortly after joined the Agronomy Department at the University of Florida, in Gainesville, FL for his Masters of Science degree. In Florida, under the coordination of Dr. Lynn Sollenberger, he worked as Graduate Research Assistant, developing a project on testing limpograss hybrid lines under grazing. As fruit of that and previous work, two of the tested lines are now being planted by Florida’s Cattlemen, benefiting the livestock industry in the region. In 2014, back in Porto Alegre, Marcelo joined the Grazing Ecology Research Group, to work on his Ph.D. under the coordination of Dr. Paulo Cesar de Faccio Carvalho, working on the native grasslands line of research. During his Ph.D., he spent one year at the University of California – Davis, developing the modeling project which was part of his thesis with Dr. Emilio Laca, and spent one month at the Institut National de la Recherche Agronomique(INRA), in Clermont-Ferrand, France, working with Raphël Martin and Dr. Juliette Bloor on the implementation of the model. Being back in Brazil during his PhD allowed him to work at the family ranch part time, an activity always loved and missed when abroad.

From 2014 to 2017, Marcelo worked as ambassador for Farmfair International, an event promoted by Northlands, in Edmonton, Canada, where he took groups of Southern American producers to visit one of the largest livestock shows in Canada, and local producers in Alberta. He also develop a volunteer extension project on feral hog management with the Equipe Javali no Pampa, resulting in the publication of a technical book on feral hog biology and control techniques, as well as many extension handouts and scientific publications. Upon finishing his PhD, Marcelo started came to the University of Florida as a post-doctoral fellow, working for Dr. Esteban Rios. In January 2018, he officially joined the faculty of the Agronomy Department at the University of Florida, as Assistant Professor. In the role of Forage Extension Specialist, Marcelo has been helping extension faculty and farmers in the state of Florida, working on forage production and management for beef cattle, dairy cattle and horses, and on integrated crop-livestock systems. His professional goals are to better understand forage-livestock systems around the world, and help developing sustainable practices to improve livestock production and agroecosystems, from a global, systemic view.
