Quan Long

  • Adjunct Assistant Professor

Biography

Quan Long, PhD, was trained in both mathematics and computer science. He is an Assistant Professor in the Communing School of Medicine with adjunct appointment in the Department of Mathematics and Statistics. His current research focuses on phenotype predictions and gene mapping via integration of multiscale –omics using statistics and informatics. He is also interested in within-host evolutionary analysis using sequences data that may lead better prediction of disease status such as cancer progression and pathogen antimicrobial resistance. He was a staff R & D engineer analyzing memory leak at IBM Research; then a staff scientist serving for the 1,000 Genomes Project and other evolution-focused projects at the Wellcome Trust Sanger Institute. Afterwards, he assumed the position of a postdoc fellow at the Gregor Mendel Institute, working on statistical methods development as well as real data analysis for DNA sequencing-based variants calling, association mapping, and population genetics. Before joining University of Calgary, he was an assistant professor (research track) in Icahn School of Medicine at Mount Sinai, working on phenotype predictions and gene expression networks.
