Scholarship
I’m a structural biologist interested in the Origins of Life, Astrobiology, and related fields.
With a background in structural biology and biochemistry, I work on Aerosols and the Origins of Life. Dispersal by wind, or Anemochory, could have played a major role in spreading Life’s building blocks on the early Earth. My work at the University of Alberta shows its potential implication in the emergence of protocells through a model of aerosol to vesicle transformation.
Throughout my career, I have been part of multi-disciplinary teams conducting research at the interface of biology, chemistry and physics. I was fortunate enough to explore experimental and theoretical techniques, manage projects and supervise students. Additionally, I have thought master’s level courses, led the setup of a research laboratory and created a 3D printing service that supports research and education.
