" My research focuses on understanding the dynamic molecular changes that occur during tumour progression and metastasis through liquid biopsy. Our ability to study tumour biology and uncover new approaches to prevent and treat cancer is limited because it relies on tissue from a biopsy, which carries several issues: inadequate sampling, rare but serious complications, and, importantly, the limitation of having one static picture of the tumour – thereby neglecting the dynamics of tumour evolution. To overcome these issues, my lab tracks tumour evolution through a liquid biopsy, a minimally invasive approach to monitor disease progression, recurrence and treatment response using a blood sample. Detection of circulating tumour cells, DNA and extracellular vesicles can contribute to early diagnosis and personalized management. Liquid biopsy can inform on the changing mutational status of the disease and help to guide therapy. My lab works towards identifying specific initiating and metastasis-promoting mutations that can track disease through ctDNA as a biomarker. We also study the contribution of EVs to cancer progression, and synthesize lipid nanoparticles to study EV behaviour and as a drug delivery system for anti-cancer therapy. "  (Summary taken from



Julia Valdemarin Burnier, PhD

Principle Investigator

Dr. Burnier pursued a PhD in molecular and cell biology at McGill University (Experimental Medicine). The focus of her PhD was the molecular mechanisms underlying invasion and metastasis. Dr. Burnier went on to pursue related post-doctoral training at McGill and at the Centre for Genomic Regulation (Barcelona, Spain). Most recently, she focused on cancer genomics in clinical trials at the Princess Margaret Hospital (Toronto).

In 2018, Dr. Burnier began an independent research program within the Cancer Research Program (CRP) of the Research Institute of the McGill University Health Centre (RI-MUHC) to uncover the role and mechanisms of tumor-derived (circulating) molecules in tumor progression and metastasis. Our goal is to develop novel accurate and sensitive biomarkers and identify new targeted therapeutic strategies. Using liquid biopsy samples and cell models, we investigate the role of circulating nucleic acids and tumour-derived extracellular vesicles (EVs) in mediating tumour metastasis via communication with and reprograming of the tumor microenvironment.

Tad Wu

MSc Student

My name is Tad Wu and I am a newly admitted master's student in the Department of Pathology under the supervision of Dr. Julia Burnier. I earned my bachelor's in Honours Computer Science and Biology. During my undergrad, I was fortunate to be given the opportunity to conduct an honour's project under the supervision of Dr. Maria Vera Ugalde, where I used a computational pipeline to analyze the distribution and colocalization of heat shock protein mRNAs in neurons of ALS patients to determine if ALS would affect the heat shock response. After taking a class on human genetics, I became particularly interested in cancer. My project will aim to mimic cancer-derived extracellular vesicles (EVs) using lipid-based nanoparticles in terms of cellular uptake and downstream effects.
