Pamela Ruegg, DVM, MPVM
David J. Ellis Chair in Antimicrobial Resistance
Dr. Pamela Ruegg is the David J. Ellis Chair in Antimicrobial Resistance and director of the Antimicrobial Stewardship and Dairy Health Management Laboratory. Her research interests include using epidemiologic techniques to solve critical issues related to animal health and milk quality and bridging the gap between research and practical applications on dairy farms.
Ruegg’s professional reputation is documented through her extensive publications, invited national and international presentations, and robust extramural funding record. Ruegg is part of a multi-disciplinary team of scientists on a USDA-funded grant project that studies how the intestinal microbiome of dairy cattle affects antibiotic resistance, a problem plaguing farms across the country. Ruegg has also received numerous awards for research and extension programs.
Zelmar Rodriguez, DVM, PhD
Zelmar Rodriguez is a veterinary epidemiologist working as a postdoctoral associate at the Antimicrobial Stewardship and Dairy Health Management Laboratory. His research focuses on the development of applicable tools for early mastitis detection and treatment efficacy, aimed to guide dairy producers and advisors on judicious and optimal decision-making regarding antimicrobial usage strategies. He answers research questions by applying an array of advanced quantitative epidemiological methods and statistical models such as GLM, correlated residual models, multilevel modeling, and machine learning. Zelmar obtained his DVM degree from the University of Uruguay and worked for a few years as a field veterinarian in the dairy industries of Uruguay and New Zealand. He obtained his PhD degree in veterinary epidemiology at the Veterinary College of the University of Minnesota. Besides research, Zelmar enjoys outdoor activities with his son and wife.

Quinn Kolar is currently a third-year PhD student in the Animal Science Department. Quinn’s research focuses on evaluating antimicrobial therapy and non-pharmacological alternatives for the treatment of mastitis in dairy cattle. Quinn developed a passion for mastitis research during her undergraduate studies at Cornell University while working for Quality Milk Production Services. After graduation from Cornell, Quinn worked in industry before pursuing her masters at the University of Edinburgh's Royal (Dick) School of Veterinary Medicine. Quinn is passionate about sharing her love of dairy cows and science with consumers to help them understand where their food comes from. When she is not busy conducting research, she enjoys gardening, traveling, and spending time at her family's cottage in Northern Michigan.
Lara Bastos is currently a PhD student under the guidance of Dr. Pamela Ruegg at Michigan State University with a project focused on combining laboratory work with epidemiological analysis of dairy records to guide treatment decisions for mastitis. Bastos has a veterinary degree from the Pontifical Catholic University of Minas Gerais (PUC Minas) in Brazil and a master’s degree in veterinary medicine with emphasis in epidemiology and mastitis diagnosis in dairy cows, which she completed at São Paulo State University (UNESP) in Brazil. Bastos has worked on blood, urine, and milk analysis at the Diagnostic Laboratory in PUC Minas. She likes to spend her free time with her family and friends, visit new places, read books, and watch movies.
Letícia Souza is currently a first-year MS student in the Department of Large Animal Clinical Sciences. Her research focuses on determine the prevalence of infection with Mycoplasma wenyonii and Candidatus Mycoplasma haemobos in dairy calves on Michigan farms. Letícia obtained her Bachelor of Science degree in Veterinary Medicine from the Centro Universitário de Viçosa (Univiçosa) in Brazil. After graduation, Letícia worked on a dairy farm in South Dakota for one year and then carried out activities to support research and technological development on dairy farms at the University of Minnesota, through the Minnesota Agricultural Student Trainee program (MAST). In her free time, Letícia enjoys traveling, watching TV series and spending time her with friends.
