Analysis of gene expression using single molecule approaches. We use imaging techniques to study the mechanisms and kinetics of different processes along the gene expression pathway in yeast and higher eukaryotes. In particular, we combine single molecule techniques and quantitative analysis methods with mathematical modeling to gain better understanding of the general rules governing the expression of genes in complex systems.

Daniel Zenklusen est titulaire d'un doctorat en microbiologie de l'Université de Lausanne et a effectué des études postdoctorales dans le laboratoire de Robert H Singer à l'Albert Einstein College of Medicine à New York. Il est professeur au Département de biochimie et médecine moléculaire de la Faculté de médecine de l'UdeM depuis 2010.
