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.

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.

Ireyon is a first-year master’s student in the Comparative Medicine and Integrative Biology (CMIB) program at Michigan State University. She earned a bachelor’s degree in animal sciences from Southern University Agricultural and Mechanical College in Baton Rouge, LA. Her research focuses on investigating the association between antimicrobial use and antimicrobial resistance in mastitis pathogens. In her free time, she enjoys cooking, listening to music, and watching documentaries.

Cara Robison is a research technician II. She received her BS degree in biology from Truman State University and completed her master's degree in animal science from the University of Kentucky with a specialization in equine exercise physiology in 2000. She joined the Department of Animal Science at MSU in 2000 and completed her PhD in 2013 while working as a research technician. Cara has assisted with applied research projects work for multiple faculty in different species including horses, poultry, pigs, and dairy cattle. She currently provides support in the Antimicrobial Stewardship and Dairy Health Laboratory of Dr. Pamela Ruegg. When Cara is not working, she enjoys riding her horse, working with her dairy goats, and spending time with her daughter and husband.

Letícia Souza is a Research Technologist II. She completed her master’s degree from Michigan State University with emphasis on the prevalence of hemotrophic mycoplasma in dairy calves on Michigan farms. Her academic journey began with a bachelor of science degree in veterinary medicine from Centro Universitário de Viçosa (Univiçosa) in Brazil. After graduation, Letícia gained valuable hands-on experience by working on a dairy farm in South Dakota for a year. Subsequently, she actively contributed to research and technological development on dairy farms at the University of Minnesota through the Minnesota Agricultural Student Trainee program (MAST). Beyond research, Letícia finds joy in outdoor activities and spending quality time with friends.

Dr. Jaimie Strickland is a post-doctoral researcher in the Ruegg Lab. Her research focuses on a few key areas: 1. Understanding the barriers to antimicrobial stewardship on dairy farms; 2. Assessing the effects of antimicrobial usage benchmarking and increased awareness of the economic impact of treatment protocols on the engagement of producers and veterinarians in antimicrobial stewardship; 3. Improving access to benchmarking tools for smaller dairies; 4. Assessing the impact of antimicrobial use on dairy farm workers; and 5. investigating other benchmarking tools to inform producers and veterinarians on individual farm disease burden and treatment protocols to support management decisions to improve animal welfare, food safety, and farm profitability.

She has bachelor's and veterinary degrees from Michigan State University, where she also completed a residency in comparative nutrition and toxicology and a master's degree in nutritional immunology. She then began a PhD program with Dr. Lorraine Sordillo, investigating the intersection of bovine immunology, vitamins, and mammary gland health. After Dr. Sordillo’s untimely and tragic passing in 2021, Jaime completed her research under the mentorship of Dr. Ruegg. She then gained experience in the pharmaceutical industry with data science, adult education, and the use of data to inform and support dairy producers and veterinarians. Jaimie is delighted to be working under the guidance of Dr. Ruegg again.

Trina VanAtta is a part-time outreach specialist for Dr. Ruegg. She enjoys sharing scientific research with the Michigan dairy industry to help them remain profitable and sustainable. Trina has a bachelor’s degree in plant sciences from Cornell University and a master’s degree in agriculture from Colorado State University. Prior to working in the Antimicrobial Stewardship and Dairy Health Lab, she worked in the MSU Plant and Soils department evaluating new potato varieties. When she is not at work, Trina enjoys spending time with her family, doing home renovation projects, and taking her therapy dog Scooter to visit local nursing homes.

Phuong Hoang is currently a PhD student in Viet Nam. She is in the Faculty Exchange Program between MSU and Tay Nguyen University, Viet Nam. She is under the guidance of Professor Pamela Ruegg as her mentor at Michigan State University with a project focused on evaluation of antibacterial potentials of medicinal plants against pathogens isolated from cow’s milk. Phuong Hoang has a veterinary degree from Tay Nguyen University in Viet Nam and a master’s degree in Animal Science with emphasis in vaccine trials for enteric haemorrhagic disease in turkeys, which she completed at the University of New England in Australia. She loves to spend her free time with her family and friends, reading books and visiting new places.
