*I am currently recruiting graduate (MSc, PhD) and undergrad (BSc Honours thesis, MITACS, USRA) students.

I am a cell physiologist and my research lab uses genetics, biochemistry, advanced microscopy and synthetic biology to study: (1) fundamental lysosome biology in health and disease, and (2) extracellular vesicles as novel therapeutics.

Whether they know it or not, everyone recycles. This is because every one of the billions of cells that make up you and I constantly recycle biomaterials using specialized tiny organelles called lysosomes. Lysosomes are an essential source of nutrients for cells and breakdown toxic biomaterials that accumulate as cells age. My lab uses baker's yeast (S. cerevisiae) and its vacuolar lysosome as models to study the molecular mechanisms underlying fundamental lysosome biology and how they promote longevity or contribute to age-related diseases.

Extracellular vesicles are tiny packages shared by all eukaryotic cells (from yeast to human) that mediate intercellular communication underlying diverse physiology, from immune responses to tissue development, suggesting they have enormous therapeutic potential. My group is using baker's yeast as a platform to engineer humanized yeast extracellular vesicles to hijack these processes with the aim of developing new therapeutic applications.

Research interests

Daniel Dagenais is member of the Collectif Société and on the editorial board of the journal Cahiers Société (a journal and research group founded by the late Michel Freitag). My work can be divided into three domains of reflection: a strong concern for social theory, namely the meaning of the renewal of sociological theory from the 1980s onwards (he edited: Hannah Arendt, le totalitarisme et le monde contemporain, PUL, 2003), including theories of identity. I am also concerned with the transformation of the family institution (see my book, The (Un)Making of the Modern Family, UBC Press, 2007).My research also focuses on contemporary suicide (centrally, youth suicide). This brought me to try and distinguish, more theoretically, historical semantics of suicide from the Ancient world to the present. I teach Introduction to society, Contemporary sociological theory, The Family, and the Sociology of suicide.
