Mariana Fonseca graduated as a veterinarian from the Universidade Federal de Viçosa, Brazil, in 2014. During her DVM studies, she participated in an agricultural education program in Denmark, a collaboration between Universidade Federal de Viçosa and Centrovice (Agricultural Consultancy Service, Denmark). Over the course of 18 months, she gained hands-on experience in animal management across all stages of production, disease control, milk production monitoring, production data analysis, and the maintenance of animals and technology, including robots and other advanced machinery. After completing her DVM, Mariana pursued a master’s degree in veterinary science at the Universidade Federal de Lavras. Following her master’s, she spent three months as a guest researcher at Aarhus University in Denmark, focusing on epidemiology and animal health. A pivotal moment in her career came during her Ph.D. at the University of Prince Edward Island, Canada, where her research centered on implementing and evaluating an on-farm surveillance system for antimicrobial use (AMU) and antimicrobial resistance (AMR) on Canadian dairy farms, through the Canadian Dairy Network for Antimicrobial Stewardship and Resistance (CaDNetASR). Currently, Mariana is a postdoctoral fellow at the Faculty of Veterinary Medicine, Université de Montréal, under the mentorship of Drs. Simon Dufour and Jean-Philippe Roy. She is conducting extensive database analysis on mastitis, further deepening her expertise in epidemiology. Mariana’s research interests focus on applying epidemiological methods to improve animal health, welfare, and the sustainability of the dairy industry. She is also committed to advancing the “One Health” approach. She then worked as a research officer at UdeM's Faculty of Veterinary Medicine on various projects such as: the longitudinal disease surveillance network for Canadian cow-calf enterprises, data analysis on multispecies antibiotic use, euthanasia in cattle and clinical trials on intranasal vaccines in grain calves. Since September 2020, she has been completing her PhD in epidemiology at UdeM's Faculty of Veterinary Medicine under the supervision of Simon Dufour, Jean-Philippe Roy and Gilles Fecteau. She is interested in the surveillance and control of bovine viral diarrhea.

Vitoria Régia Lima Campêlo graduated in veterinary medicine from the University of Brasilia, Brazil in 2019. During her studies, she developed a passion for the diagnosis and control of infectious diseases through the various internships she carried out with government agencies such as Brazil's Ministry of Agriculture for the control of infectious diseases in cattle, pigs and horses. She then carried out a research internship on the diagnosis of glanders and equine infectious anemia in a veterinary laboratory. This inspired her to acquire further knowledge in epidemiology. Since January, she has been doing her master's degree in epidemiology at the Faculty of Veterinary Medicine of the Université de Montréal, under the supervision of Simon Dufour, Cécile Aenishaenslin and Manon Racicot. She is interested in the obstacles to implementing biosecurity on Canadian dairy farms.

Faustin Farison is an agricultural engineer who graduated from Bordeaux Sciences Agro in 2020, specializing in sustainable animal production. He then took a master's degree in epidemiology at the École Nationale Vétérinaire d'Alfort, graduating in 2021. During his studies, Faustin took part in a project aimed at estimating the risk of contact between badgers and cattle as part of the bovine tuberculosis control plan. He also worked on the development of a barrier flora solution aimed at preventing the onset of intramammary infections. After working for nearly a year as a health advisor for a French health protection group, he joined the Faculty of Veterinary Medicine at the Université de Montréal in May 2022 to complete a Master's degree in Veterinary Science. After an accelerated transition from master's to doctorate, he has now been completing his doctorate in epidemiology since May 2023, under the supervision of Juan Carlos Arango-Sabogal, Simon Dufour and Pablo Valdes-Donoso. Faustin is interested in the application of machine learning for the development and validation of classification models to determine the infection status of farms based on their biosecurity profiles.

Marie-Pascale Morin obtained her bachelor's degree in biology from the Université de Sherbrooke, Québec, Canada in 2015. During this, she completed her first research internship in the vegetable industry, followed by another internship at Agriculture Agri-Food Canada in Lennoxville, Quebec, Canada on the biology of dairy cow lactation. She obtained a Master of Veterinary Science (Clinical Sciences) from Université de Montréal (UdeM), Québec, Canada in 2018. She then worked as a research officer at UdeM's Faculty of Veterinary Medicine on various projects such as: the longitudinal disease surveillance network for Canadian cow-calf enterprises, data analysis on multispecies antibiotic use, euthanasia in cattle and clinical trials on intranasal vaccines in grain calves. Since September 2020, she has been completing her PhD in epidemiology at UdeM's Faculty of Veterinary Medicine under the supervision of Simon Dufour, Jean-Philippe Roy and Gilles Fecteau. She is interested in the surveillance and control of bovine viral diarrhea.

Karol Gilberto Solano Suarez graduated as a veterinary surgeon from the Universidad Nacional de Colombia, Colombia in 2012. He then worked as an independent veterinarian in dairy cattle medicine around Bogota, Colombia. His first internship was with Aurora Organic Dairy in Texas, USA, where he acquired his first research skills investigating the effects of calcium administration during the transition period and the effect of transrectal palpation on calf development and survival. He then completed a second internship in South Australia, Australia where he coordinated the day-to-day operations of a pasture-based robotic and conventional milking system. In 2019, he completed a Master's degree in Animal Science (Dairy Herd Health) at Colorado State University, Colorado, USA. Since January 2021, he has been completing his doctorate in veterinary sciences (epidemiology) at the Université de Montréal's Faculty of Veterinary Medicine under the supervision of Simon Dufour, Jean-Philippe Roy and Juan Carlos Arango Sabogal. He is interested in the surveillance and control of bovine leukemia.

William Lelorel Nankam Nguekap obtained his bachelor's degree in medical biology (2016) and a master's degree in medical microbiology (2019) from the Université de Montagnes (Cameroon). Driven by the desire to become an excellent teacher-researcher, William completed an internship as an instructor of practical and directed work (February-September 2020) and then held the position of Attaché temporaire d'enseignement et de recherche (ATER) at the Université des Montagnes (February 2021-April 2022). William was involved in research in Cameroon on human hematological reference values and antibiotic resistance in farms, hospitals and the community. In May 2022, he began a master's degree in veterinary science with a specialization in epidemiology at the Université de Montréal's Faculty of Veterinary Medicine, under the supervision of Juan Carlos Arango Sabogal, Jean-Philippe Roy and Nathalie Bissonnette. In 2023, he completed a fast-track PhD in veterinary sciences, with an option in epidemiology, at the same faculty and under the same supervision. He is interested in the prevalence and evaluation of screening strategies for Mycobacterium avium subsp. paratuberculosis (MAP) in Canadian dairy herds.
