Research Associate


I received my master’s degree in the Department of Veterinary Science of the Szent Istvan University in Hungary and my PhD at the Semmelweis University. During my undergraduate and PhD student period I worked as an experimental geneticist searching for disease causing mutations in human. Between 2007 and 2015 I switched to the field of structural biology in the research group of Peter Tompa in the Institute of Enzymology, Hungarian Academy of Sciences. During this time I did bioinformatics analyses in the field of intrinsically disordered proteins, especially in the field of their evolution. In October 2015 I joined the Department of Veterinary Medicine and worked on canine genetics in the research group of Dr. David Sargan. In March of 2018 I joined the MRC-AMR research group led by Dr Mark Holmes and Dr Andrew Grant, and I have been working on the in vivo tracing and discovery of antimicrobial resistance genes.

Research Interests

Tracking antimicrobial resistance gene transfer in human and farm animal gut bacterial communities

Antimicrobial resistance (AMR) is an urgent and growing global public health threat. The controlled and uncontrolled usage of antibiotics in human medicine and in animal farming put selective pressure on the gut microbiota that leads to the continuous emergence of novel AMR genes, and their potential exchange between prokaryotic species. As a part of highly collaborative team my task is to build up and maintain the bioinformatics pipeline to analyse metagenomics and HiC sequencing data to trace the potential AMR gene transfers.
