Mathieu completed his Ph.D. in Human Genetics in 2020 under the supervision of Dr. Silvia Vidal at McGill University. Mathieu’s doctoral work focused on virus infections of the heart and of the brain. Specifically, he investigated how genetic variation can influence whether a protective or a lethal inflammatory response is generated against infection. In Dr. Langlais’ lab, Mathieu is currently using bulk and single-cell genomic approaches to study the development and progression of chronic autoinflammatory diseases.


Wilian Macedo, bioinformatician

Wilian is concluding a Ph.D. degree under the supervision of Dr. Erwin Schurr at department of Biochemistry. His projects are focused on bioinformatic analysis of the transcriptome responses mounted by human cells challenged with mycobacteria. In the context of tuberculosis/HIV, his work described the impact of ART regimen on alveolar macrophages challenged with Mycobacterium tuberculosis. In leprosy, he characterized the whole blood transcriptome program of patients that developed T1R, a delayed hypersensitivity reaction, before its onset. Now working as a bioinformatics analyst at C3G and in support to Drs Langlais’ and Fritz labs, he is tasked with supporting the analysis of various projects in immuno-genomics



I am an international student from the UK, where I studied medical sciences at the University of Southampton. After graduating I worked in industry for a couple of years doing research and development in the microbiology sector, but it has always been an ambition of mine to move into genetics. Outside of work, I am a very keen cyclist and mountaineer, and I’m looking forward to lots of skiing during the Quebec winter!


ATIA AMIN, PHD candidate

Atia is a PhD student co-supervised by Prof. David Langlais at the department of Human Genetics and Prof. Mathieu Blanchette at the department of Computer Science. Her research is based on bioinformatics and machine learning approaches to identify biomarkers of pathogens causing vector borne diseases. Before starting PhD, she completed her master’s in Molecular Biology at the University of South Dakota, USA, and undergraduate degree in Microbiology at the University of Dhaka, Bangladesh. Her hobbies include playing guitar, singing songs, and listening to music.



I have a bachelor's degree in microbiology that I completed at Sherbrooke University, and I also have a background in biomedical analysis in college. I am currently doing a master's degree in the laboratory of Dr. Christopher Fernandez-Prada, co-directed by Dr. David Langlais and Dr. Martin Olivier. I am interested in the characterization of extracellular vesicles released by different isolates of Leishmania, the causative agent of visceral leishmaniasis, in order to identify new sensitive biomarkers for rapid and non-invasive diagnosis of the disease. In my spare time, you will find me outdoors on a lake or on a climbing wall !

Co-supervised by Dr. Langlais and Dr. Ana Nijnik, Jacky is a PhD student in the department of Physiology. Currently, he studies the stress response of hematopoietic stem cells (HSCs) in the context of progenitor cell differentiation and HSC survival. Importantly, he is working towards investigating potential gene targets to enhance bone marrow stem cell fitness when exposed to DNA-damaging stress, a signature off-target side effect of cancer therapies. Outside the lab, you will often have to be given a 10-digit coordinate in order to find Jacky. Wherever his location is, he is probably searching for personal growth and challenges while giving his best. "Deeds not words", a phrase that deeply inspired him.

She hopes to use the tools learned in her PhD to help answer patient-driven questions from her future practice. She previously did her MSc in Microbiology and Immunology at McGill under Dr. Antel exploring factors affecting oligodendrocyte myelination potential. In her spare time, she enjoys reading, playing board games, and practicing martial arts.


Catherine [qianqian] Lyu, MSc CANDIDATE

I am a Human Genetics M.Sc student who took my undergraduate studies at McGill in Biology. I am interested in molecular genetics, autoimmune diseases, and possible treatments. My research is related to Hashimoto Thyroiditis, which is the most common autoimmune disease, using the EAT mouse model. Outside the lab, I enjoy camping and I am an absolute animal lover.


Simon gagnon, MSc CANDIDATE

Hello! I studied microbiology and immunology at the Université de Montréal. I developed a new interest in parasitology after a class given by Dr. Fernandez Prada, and that gave me an opportunity to do an internship in his lab. The subject of my Masters’ thesis is on the interaction between Giardia parasites and cell rendered immunodeficient upon treatment by the drug given to transplant patient. Hopefully, this study will give us more information about the risk of zoonotic disease transmission for immunodeficient patient. Outside of work, you can find me doing all kind of sports and outside activities.

Co-supervised by Drs Christopher Fernandez-Prada and Mélanie Dieudé



I am a third-year undergraduate student in the Interdepartmental Honours Program in Immunology with an interest in immunology-related research and understanding the molecular mechanism of inflammation. In Dr. Langlais’ lab, I will be investigating the role of CEBPd in macrophage activation and trained immunity. Outside of the lab, I enjoy cooking, running, skiing, and a good game of chess. I also recently discovered my interest in bouldering.


Étienne collette, MSC student

I am currently finishing the third year of my bachelor’s degree at Université de Montréal in biochemistry and molecular medicine. Having done a technical degree in biotechnology and spent a year and a half at the Canadian Centre for Computational Genomics, I have always been interested in both wet and dry lab techniques. In Dr. Langlais’ lab, I am studying the effects of glutathione and (1–3)-β-D-glucan on macrophage epigenetic memory and how these products modulate the activity of target transcription factors. If you ever find me out of the lab, I will probably be tinkering on my computer, trying out some new recipes, or hiding behind my game master screen, preparing my next game of dungeon and dragons!
