Hugh Couchman

Hugh Couchman is a Canadian astronomer and professor at McMaster University. He is a computational astrophysicist who studies the growth of structure in the universe via gravitational N-body simulations.

Early life and education

Couchman received both his undergraduate and graduate degrees from Cambridge University. In his final year as an undergraduate, he took a course in astronomy taught by Martin Reese, which sparked his interest in cosmology.[1] In 1986, he completed his Ph.D. from the Institute of Astronomy at Cambridge.[2]

Career

After finishing his PhD, Couchman moved to Canada to begin a postdoctoral fellowship at the Canadian Institute for Theoretical Astrophysics. He spent some time as an assistant professor in the department of Astronomy at the University of Toronto, before beginning a position at the department of physics and astronomy at the University of Western Ontario in 1991.

In 1999, he moved to the department of physics and astronomy at McMaster University. There he helped found SHARCNET, a consortium of universities in South Western Ontario that have joined high performance computers together by optical fiber. He is also a member of the Virgo Consortium for Cosmological Supercomputer Simulations, an international collaboration which performs state-of-the-art cosmological simulations of the large scale structure of the Universe.[1]

gollark: Technically no, if you know all the other participants and their order.
gollark: I couldn't make it work properly, so I'm working on other things instead.
gollark: ```The "apiomemetics" strategy will be as follows:- if this is the first turn, fork process- if you are the parent process, wait for the child to terminate- if child, use a strategy and see how well it goes- at 100th turn (matches are AT LEAST this long), if child, send message to parent via shared memory and exit- repeat with different strategy- store best strategy against current opponent somewhere, use on all subsequent turns```
gollark: And also it infinitely loops somehow.
gollark: Right now it doesn't actually test it.
