Etienne Caron, PhD


Etienne Caron was recruited at the CHU Sainte-Justine Research Center at the Université de Montréal in September 2018 to develop an innovative research program in mass spectrometry and cancer immunotherapy. Etienne did is PhD training in the group of Prof Claude Perreault at the Université de Montreal and his postdoc at ETH-Zürich in the laboratory of Prof Ruedi Aebersold, a pioneer and world-leader in the field of proteomics and mass spectrometry. During his postdoctoral training, he has contributed to the development of the SWATH/DIA technology to advance the field of immunopeptidomics and immunotherapy. Etienne also became a world-leader in the field, founding and chairing the Human Immuno-Peptidome Project, an international initiative reuniting top leaders in mass spectrometry and immunology. His PhD and postdoctoral training has led to the publication of 23 papers in high-impact journal including Immunity, eLife, Cell Rep and Nature.

Isabelle Sirois, PhD


Following Biochemistry and COOP studies at the University of Ottawa, Isabelle completed a PhD with Drs Marie-Josée Hébert et Alexey Pshezhetsky at the Université de Montréal from 2004 to 2011. During her PhD, she characterized the secretome of apoptotic/autophagic cells using mass spectrometry and described unconventional modes of secretion relevant to chronic allograft rejection. These findings were published in significant journals including Cell Death and Differentiation and Autophagy.  Isabelle completed a postdoc training with Dr Mark Basik lab and his team at McGill University. Later, she joined the team as a Research Associate.  Her work described novel molecular vulnerabilities in chemoresistant TNBC tumors. Isabelle is now a Research Associate and Lab Manager at CARONLAB since Novembre 2018.

Kevin Kovalchik, PhD

Postdoctoral Scientist

Following a Bachelor of Music and Bachelor of Science in chemistry at The University of Idaho and Oregon State University, Kevin completed his PhD studies in analytical chemistry at The University of British Columbia with Drs. David D.Y. Chen and John V. Headley. During his time there he focused on method development for the characterization of organic components in tailings ponds using mass spectrometry, and closely collaborated with Drs. Gregg B. Morin and Christopher S. Hughes in the creation of software tools for interrogating raw mass spectrometry proteomics data. Kevin  was recruited to the Caron Lab at the CHU Sainte-Justine Research Center in September 2019 to implement a web based peptide antigen database and develop tools for monitoring the performance of mass spectrometry data acquisition.

Co-supervision with Dr. Mathieu Lavallée-Adam


Nadia E. Chauca-Torres

PhD Student

Co-supervision with Dr. Sonia Cellot

Nadia has a bachelor’s degree in Biology from the National University of San Marcos (Peru), where she worked on the research of immunomodulatory and antitumoral products from synthetic and natural sources. She also has a master’s degree in Immunology from the University of Sao Paulo (Brazil). During her training she evaluate the immune response on patients with glioblastoma multiforme submitted to a dendritic cell base immunotherapy, developing a 3D cell platform to evaluate the influence of the tumor microenvironment on immune cells.

As a part of Dr. Caron’s team, Nadia will be working on the searching of fusion gene derived neoantigens in pediatric AML/ALL as targets for developing better strategies for immunotherapy.


David Hamelin, B.Sc.

Master Student

Co-supervision with Dr. Julie Hussin

David completed his BSc in biochemistry (CO-OP) at the University of Victoria, throughout which he had the opportunity to conduct research projects in world-renowned laboratories. These research opportunities allowed him to acquire significant experience designing and conducting mass spectrometry-based experiments, and culminated in co-authorship in 7 publications (NatureComms, PNAS, JMedChem, JBiolChem, JMolBiol) while in Dr. John Burke’s team at Uvic.

As part of Dr. Caron’s team, David seeks to combine his background in mass spectrometry with a newly found passion for computer science to contribute to the field of immunopeptidomics.


Frederic Saab, B.Sc.

Master Student

Frederic has just started his Master’s degree after having held several jobs in companies, he has completed a Bachelors of Science in Biochemistry at the Université Saint-Esprit de Kaslik in Lebanon and a bachelors in Psychology at Mykolas Romeris University in Lithuania. During his Psychology degree, Frederic had the chance to volunteer in a leading Infectious diseases research institute in Lithuania where he had the chance to work with bright scientists and collaborate with a University in Lithuania and Weil Cornell in the U.S in research projects focused on molecular epidemiology of E. coli & L. pneumophila.

As part of Dr. Caron’s team, Frederic will be delving into, as well as combining his interests in the fascinating worlds of immunology, mass spectrometry and computer science.

Bayrem Gharsallaoui


After completing a DEC in natural sciences, Bayrem is now completing a Bachelor in Biomedical Sciences at the Université de Montréal as an intern in the Caron Lab at the CHU Sainte-Jutine Research center. Passionate about sciences and genetics, Bayrem has the aspiration to continue his studies towards the higher cycles of the master’s degree and the doctorate in his field.
