Profile
Research expertise
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.
Biography
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.

Recruitment in research
Multiple PhD and postdoctoral positions are available in the Zenklusen laboratory. Available projects aim to study fundamental aspects of RNP biology (including the biology in introns and other coding and non-coding RNAs), to decipher mechanisms that facilitate the formation and composition of RNA-protein complexes, their topological organization, and how this facilitates gene expression. Moreover, we want to understand, how defects in RNPs lead to various disease phenotypes, including cancer and various neurodegenerative diseases. Projects will employ multidisciplinary approaches in the areas of single-molecule and super-resolution microscopy, RNA/protein biochemistry, genomics and CRISPR-Cas9-mediated genome editing, using mammalian cell culture models.
Applicants should have expertise/undergraduate degree in cell biology, biochemistry and/or biophysics and experience in working with RNA, RNA-protein interactions and/or single molecule biophysical methods.
Interested applicants should email a CV and letter of introduction, proposed start date, a list of publications (for postdoc candidates), names of two or three references who may be contacted for letters, and a brief description of future research interests to daniel.r.zenklusen@umontreal.ca
