Dr. Gustavo Machado is a 2010 graduate of the Veterinary College at the Federal University of Santa Maria, Brazil. Dr. Machado completed a Master of Science in veterinary epidemiology at the Federal University of Rio Grande do Sul in Brazil in 2013.

Dr. Gustavo developed machine learning tools applied to epidemiology while pursuing his PhD in 2016. In 2016 he held a position as assistant professor in the Department of Preventive Veterinary Medicine of the Federal University of Rio Grande do Sul.

He subsequently completed a postdoctoral associate position in the Veterinary Population Medicine Department, at the University of Minnesota. In January 2018, he was appointed as an Assistant Professor in the Department of Population Health and Pathobiology at the North Carolina State University College of Veterinary Medicine to lead research on transboundary epidemiology.

Dr. Machado's main research focus is to investigate the occurrence and spread of animal infectious diseases, especially transboundary disease, providing science-based support for decision making with regard to prevention and control. Currently, Dr. Machado's research is focused on mathematical modeling and traditional statistics for practical mapping of the spread of infectious diseases among pig populations. Dr. Machado has authored or co-authored more than 137 peer-reviewed publications in the field of animal disease and epidemiology.

In addition to all the exciting developments in the lab, Dr. Machado has a long standing interest in teaching disease epidemiology and developing and deploying capacity building for official veterinary services nationally and internationally.

Abagael graduated with a BSc in Biological Sciences from the Royal Veterinary College, UK, in 2019 and went on to graduate with a MSc in Epidemiology from Imperial College London, UK, in 2020.

During both her BSc and MSc, Abagael was involved in modeling the seroprevalence of neglected zoonotic diseases such as Toxoplasma gondii and Echinococcus granulosus, as well as contributing to COVID-19 research on non-pharmaceutical interventions. Additionally, during her BSc, Abagael spent a year in the pharmaceutical industry researching animal models of infectious disease.

At the start of 2021, Abagael started her PhD in Population Health and Pathobiology at North Carolina State University, within the Machado lab with a research focus in machine learning and bio-security in swine disease. Additional research interests include transmission and genetic modeling of infectious zoonotic disease.

Felipe Sanchez graduated with a Bsc in Biology from the Interamerican University of Puerto Rico, San German Campus, in 2011. He later obtained a MSc in Animal Sciences, an MHS in Environmental and Global Health, and a graduate certificate in Geospatial Analysis from the University of Florida.

After completing his graduate studies, Felipe joined the National Ecological Observatory Network (NEON), where he served as the lead Aquatic Field Ecologist for three years. During his time at NEON, Felipe became a certified Data Carpentry instructor, served as an instructor for several NEON Data Science workshops, and collaborated on maintaining and creating online NEON data skills tutorials.

Felipe will be joining the Machado lab as a PhD student in the Center for Geospatial Analytics in the Summer of 2021. His research will focus on using machine learning tools to investigate the spread of infectious swine diseases to support biosecurity and disease control and prevention.

Dr. Cameron Ellington is a 2020 graduate of the University of Georgia College of Veterinary Medicine in Athens, GA. Prior to attending veterinary school, Dr. Ellington earned her bachelors of science degree in animal and pre-veterinary sciences at Clemson University.

Following graduation from veterinary school, Dr. Ellington started a dual residency and masters program at North Carolina State University in July 2020 in an effort to focus her veterinary knowledge on poultry. Dr. Ellington had the opportunity to collaborate with the Machado Lab to study the prevalence and transmission of Salmonella within a commercial turkey flock through the use of historical data analyzed with modeling software.

Dr. Ellington plans to work as a veterinarian in commercial turkey production following completion of her residency and masters degree in July 2022.

Kelsey Mills is currently a graduate student in the Center for Geospatial Analytics at North Carolina State University. She graduated from East Carolina University with a bachelor's degree in anthropology, concentrating in archaeology and biological anthropology.

Kelsey's research interests are in the application of geospatial technologies to agricultural science and cultural resource management. In 2014, she participated in an archaeological excavation of a prehistoric site in western NC and assisted in the management of faunal artifacts. In addition to anthropological research and experiences, Kelsey has also conducted research into areas such as the spread of invasive species used in agriculture management through flooding and hydrologic modeling of storm water runoff as it relates to the spread of animal disease. Currently, Kelsey is assisting in the application of geospatial modeling as a means to limit the spread of swine diseases.
