He is also affiliated with the Department of Bioengineering and a Visiting Professor at the University of Thessaly, Greece. He is Associate Director at The Canadian Genome Enterprise, a Canadian Foundation for Innovation-Funded Major Strategic Initiative.  He has developed expertise in all fields of genomics and functional genomics. His main interest is developing state-of-the-art NGS-based approaches to disease gene identification, as well as functional genomics approaches for the identification of prognostic markers and associated pathways in gynaecological cancers and brain cancer. He leads the genomics and virus sequencing pillar of the CIHR-funded CoVARR-Net, the Canadian COVID-19  Variant Rapid Response Network.
