Carl Ernst, PhD
Carl Ernst is an expert in stem cell biology and genetic engineering and heads the Rare Neurodevelopmental Disorders Laboratory (RNDL) at The Neuro.
Professor Ernst started his professional career working as a one-on-one personal care worker with children with disabilities in schools. Working with kids and connecting with families continue to inspire his current work with the Rare Neurodevelopmental Disorders Lab at McGill. The RNDL is committed to engaging with families, modeling disease, identifying cellular phenotypes, selecting molecules for potential therapeutic uses, and advancing molecules to phase 1 clinical trials. His group has significant expertise in making brain cells and genetically engineering cells to better understand rare disease.
Carl Ernst is committed to providing an excellent training environment for trainees, including undergraduate and graduate students. He is a past winner of the Graduate Teaching Award of Excellence in the Department of Human Genetics. He has completed a 10-year award as a Canada Research Chair and is a current Senior Scholar awardee of the Fonds de Recherche de Quebec. Professor Ernst speaks French and English.
