Postdoc opening in C*-algebras related to physics
My work on K-theory and almost commuting matrices with physicists at
Sandia National Labs is growing. It is time to add a mathematics postdoc to
the mix. As such, UNM seeks "a postdoctoral fellow
with research experience in some area of C*-algebras, such as K-theory
or semiprojectivity, that is connected to current research in
topological physics" with the
full ad at the UNM job site.
Applied Math, Tenure Track, opening at UNM
Applied mathematicians whose work relates to my reserach with Alex Cerjan
may wish to apply to this. One of the prefence mentioned in the as
is for candidates "who can foster ties with other units on campus and with
local national laboratories" and Sandia National Labs (where Alex Cerjan
is located) is just across town from UNM. Please see
the
full listing
at the UNM job site.
