Muñoz-Atienza, Estefanía

Postdoctoral Research Fellow

Dr. Estefanía Muñoz-Atienza graduated in Veterinary Medicine at the Complutense University of Madrid (UCM, Spain) in 2008. She completed an MSc in Research in Veterinary Sciences in 2009 and a PhD in Veterinary Sciences in 2015 at Faculty of Veterinary (UCM) with Extraordinary Doctorate Award and trained in microbiology, molecular biology and immunology. She is interested in understanding how bacteria interact with immune cells in order to understand the mechanisms of tolerance and pathogenicity, as well as finding therapeutic alternatives, such as probiotics, in order to inhibit pathogens and avoid the use of antibiotics. 

Summary of Research

Her current research is focused on the role of oral and intestinal pathobionts in the development of rheumatoid arthritis (RA). This project is also carried out by Dr. Magdalena Flak, Senior Post-doctoral fellow, and supervised by Prof. Costantino Pitzalis, expert in RA and chronic inflammatory disease at the Centre for Experimental Medicine & Rheumatology, and Prof. Mike Curtis, expert in oral microbiota and periodontal disease at the Institute Of Dentistry. This work is supported by Arthritis Research UK.
