I am a lecturer in the School of Veterinary Medicine in University College Dublin, Ireland. I teach undergraduate students about the wonders of viruses and the diseases that viruses cause. I also manage a research team that is interested in the immune system and  how it defends the body against infection in a species specific manner.
We study viruses such as Chikungunya virus, ZIKA virus and Oropouche virus, which are all viruses spread by mosquitos and infect humans; Schmallenberg virus which causes abortions in cattle and sheep and ORF disease, which causes a pox like skin infection in sheep
I am always interested in talking to people interested in carrying out research in this area and if you would like to do a PhD or postdoc with my group please drop me an email. On the other hand, if you are just generally interested in viruses and have a question about them or about studying in UCD, please feel free to email or tweet me.

Research Interests

My group is interested in developing new therapies for the treatment of virus infections. We study the bodies immune system and how it tries to deal with invading viruses. We are increasingly focused on understanding the 'species barrier'. That is, how viruses cause disease in certain species and not others. By comprehending the molecular basis for the species barrier, we contend that more effective therapies against virus infection can be created. 


Teaching Philosophy

I predominantly teach Vet undergraduate students about viruses and the infectious diseases caused by viruses.
