She is leading a state-wide ecosystem services modeling and stakeholder engagement program to improve water quality, soil health, and crop production. She is working on Farm-to-watershed scale decision tools:

  • USDA Agricultural Conservation Planning Framework (ACPF) for locating in-field and edge-of-field conservation practices,
  • NRCS Stewardship Tool for Environmental Performance (STEP) and COMET FARM/Planner for informing payment for ecosystem services (soil carbon, greenhouse gas emissions, water quality, etc.,),
  • Soil and Water Assessment Tool (SWAT) model for evaluating effects of Ag conservation practices on water quality and soil health,
  • NOAA’s Ohio Applicator Forecast tool for managing farm nutrient applications based on forecasted risk of runoff.

Dr. Osler Ortez HeadshotDr. Osler Ortez
Assistant professor

Dr. Osler Ortez comes from backgrounds in coffee production (Nicaragua), soybean production (Kansas and Argentina), and corn production (Nebraska and the U.S. Midwest). He earned his B.S. degree from Zamorano University in Honduras (2014), his M.S. degree in Agronomy at Kansas State University (2018), and PhD in Agronomy and crop Production at the University of Nebraska-Lincoln (2021).

Dr. Grazyne Tresoldi HeadshotDr. Grazyne Tresoldi
assistant professor

Dr. Grazyne Tresoldi is an Assistant Professor of Animal Welfare Science in the Department of Animal Sciences at The Ohio State University. She was born in a small town in rural Brazil (Campo Erê, Santa Catarina), into a family deeply rooted in food production, particularly in the hospitality and meat industry. However, her passion for companion animals led her to pursue a career in Veterinary Medicine. Along the way, she discovered her true calling in the field of dairy cattle, realizing that her mission was to enhance the well-being of farm animals and champion sustainable farming practices.

To pursue this mission, she sought additional professional training in animal behavior and welfare, which granted her the privilege of collaborating with producers and institutions worldwide. This journey brought her to the US, where, prior to joining The Ohio State University, she completed her PhD at the University of California, Davis, and served as an Assistant Professor at California State University, Chico until 2023.

Her research offers significant opportunities to improve dairy cattle welfare, production, and farm sustainability. She is particularly interested in developing strategies to mitigate weather-related risks and identify the barriers and opportunities for implementing improved animal welfare practices. In both the classroom and beyond, she is dedicated to raising awareness and knowledge about food animal welfare among students, educators, and dairy industry allies, equipping them to address challenges in responsible food production. Her goal is to inspire positive change within the food animal industry for the benefit of animals and those who depend on them for sustenance.

Dr. Sam Ward HeadshotDr. Sam Ward
Assistant professor

Dr. Sam Ward started as an Assistant Professor of Forest Entomology at OSU in July 2023. After completing his PhD in Entomology at the University of Minnesota, Sam spent two years as a postdoctoral research associate in the Department of Forestry and Natural Resources at Purdue University. From 2020-2023, he was an Assistant Professor of Insect Ecology in the Department of Biochemistry, Molecular Biology, Entomology, and Plant Pathology at Mississippi State University. Sam’s research group (Landscaped Ecosystem and Forest Entomology Lab; LEAFE Lab) studies the ecology and management of insects that feed on trees. Most projects are aimed at understanding drivers of the arrival, establishment, and spread of non-native insects (invading species and imported biological control agents), with a particular emphasis on mitigating ecological and economic impacts of invaders.
