Binding of proteins to specific sites on DNA is a fundamental aspect of nuclear processes such as gene expression, DNA replication, DNA repair and others. A number of techniques such as ChIP-seq, DNase-seq, FAIRE-seq and others are used to map protein-DNA interactions at the genome-wide scale in living cells. The readout of these methods, however, comes from averaging bulk measurements from a population of cells. These methods are therefore unable to reveal the cell-to-cell heterogeneity of protein-DNA interactions and provide very limited information about the relationship between neighboring interactions on the same molecule. The primary goal of the proposed project is to overcome the above-mentioned limitations by developing an advanced technique to generate high-resolution long footprints of protein-DNA binding at single-molecule level in living cells. The methods to be developed will take advantage of a recent sequencing technique called Nanopore sequencing.
Summary of responsibilities
This project combines the use of state-of-the-art functional genomic technologies with standard biochemistry and molecular biology in Saccharomyces cerevisiae. The student/postdoc will be in charge of executing and analysing the vast majority of the experiments for the project and will be assisted during his/her training by Dr. Robert and senior members of the lab. The IRCM has several core laboratories with expertise that will enhance the training experience of the candidate.

We seek a highly motivated individual with a genuine interest in understanding the mechanistic aspects of molecular processes. A background in molecular biology and/or biochemistry is mandatory. Knowledge in bioinformatics, computer programming or statistics are assets but not mandatory. Only candidates with very good academic track records will be considered.
