Recrutement recherche

Maitrise ou Ph.D. – Épigénétique de l’oocyte et du développement

Postes pour étudiant(e)s à la maitrise ou au doctorat dans le domaine de l’épigénétique du développement chez le mammifère, au sein du Centre de Recherche en Reproduction et Fertilité (CRRF). Plusieurs projets avec l’opportunité de préparer et/ou d'analyser des données de séquençage de pointe (ChIP-seq, RNA-seq et bilsulfite sequencing) dans des tissus primaires germinaux et embryonnaires.

Projets potentiels centrés autour de la transmission et la maintenance de l’hétérochromatine maternelle chez l’embryon murin ou de l’impact épigénétique de la stimulation ovarienne et de la fécondation in vitro chez le bovin néonatal.

Les projets seront effectués à la faculté de médecine vétérinaire, située sur le campus de Saint-Hyacinthe de l’université de Montréal. Date de début : entre janvier et septembre 2022, à déterminer avec le/la candidat(e).

Les candidat(e)s intéressé(e)s peuvent soumettre leur CV et une courte lettre d’introduction à l’attention du Dr. Julie Brind’Amour (julie.brindamour@umontreal.ca).

Masters or Ph.D. – Oocyte and developmental epigenetics

M.Sc. or Ph.D. positions in the field of epigenetics of mammalian develpment. Several projects with the opportunity to prepare and / or analyze cutting-edge sequencing data (ChIP-seq, RNA-seq and bilsulfite sequencing) in primary germinal and embryonic tissues. The projects will be carried out at the Center Research Center in Reproduction and Fertility (CRRF).

Potential projects center around the transmission and maintenance of maternal heterochromatin in the murine embryo or around the epigenetic impact of ovarian stimulation and in vitro fertilization in neonatal cattle.

The laboratory is located at the Faculty of Veterinary Medicine, located on the Saint-Hyacinthe campus of the University of Montreal. Start date: between January and September 2022, to be determined with the candidate.

Interested candidates can submit their CV and a short letter of introduction to the attention of Dr. Julie Brind’Amour (julie.brindamour@umontreal.ca).

Mes intérêts de recherche sont centrés sur le processus de reprogrammation épigénétique dans les cellules germinales et de l’embryon précoce des mammifères. En particulier, je m’intéresse sur l’effet de différentes interventions ou mutations sur l’établissement de l’epigenome maternel, ainsi qu’à leurs effets secondaires sur la progéniture.

My research interests focus on the process of epigenetic remodeling during germline and early embryonic development. In particular, I am interested in the effects of various interventions or mutations on the establishment of the maternal epigenome, as well as its impact on the progeny.
