James Gurian

Postdoctoral Fellow, Perimeter Institute for Theoretical Physics

I am a postdoctoral fellow at the Perimeter Institute. I am primarily interested in the formation of the first stars in the universe and in understanding the particle nature of dark matter. I have authored some papers and published some poems. You can send me an email at jgurian@perimeterinstitute.ca.
