Swine Immunology, Chlamydia, Vaccine development
I studied biology at the Eberhard Karls University Tübingen (Germany) with a focus on molecular biology, virology and microbiology. Having become interested in immunology, I decided to perform my Diploma thesis and subsequently my PhD thesis at an immunological institute and thus joined the Institute of Immunology at the Vetmeduni Vienna. The focus of my theses was the characterisation of porcine regulatory T cells (Tregs). My following postdoctoral work was delving deeper into the function of Tregs, focusing on their part in Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) infection. Besides, I was trying to identify new markers for several T-helper cell subsets in swine and to improve flow cytometry for veterinary medicine. Thereby, we became able to characterize porcine T-helper cell subsets and Tregs phenotypically and functionally by up to eight-color flow cytometry. In addition, I was an active member of the Austrian Society of Cytometry and participated in the planning and in the execution of basic and advanced courses and seminars. In September 2013, I moved to Saskatoon, Canada to work at VIDO to extend my knowledge on host-pathogen interactions. We were using the pig as a large animal model to study the cellular immune response on intracellular chlamydia infection. Joining this well-recognized institute gave me the ability to broaden my skills including the isolation and culture of bacteria and host cells, immunohistochemistry, and confocal microscopy. The insight into a new institution with various up-to-date methods and a wide experience with vaccine development made this decision a great success. In June 2016, I started as an Assistant Professor in swine immunology at the College of Veterinary Medicine at the North Carolina State University in Raleigh, North Carolina. My lab focuses on swine health and using the pig as an animal model for biomedical research. We currently study the development of immunological memory to the major pig virus PRRSV (Porcine Reproductive and Respiratory Syndrome Virus) and use the pig as a model to study chlamydia infections and food allergy.
