About Me

Portugal, 2012.

I’m an astronomer at the Harvard-Smithsonian Center for Astrophysics primarily researching low-mass stars in the group of Edo Berger. My scientific interests also include accreting compact objects, highly-variable radio sources, and anything that pushes the limits of observational radio astronomy — especially if it involves building new software or hardware tools to do new science.

Because there are a lot of P. Williamses out there, I try to go by Peter K. G. Williams in my publications.


My CfA office is Perkin 327. My work email address is pwilliams@cfa.harvard.edu (though it just forwards to my personal address, peter@newton.cx). My postal address and phone number are listed on my CV.
