Good advice from Michael Koontz (@_mikoontz):
(2/n) 1) A profile page. This could be your own custom website, a ResearchGate page, a Google Scholar profile, etc.— Michael Koontz (@_mikoontz) September 24, 2015
(4/4) 3) An academic Twitter account. Stay current! Stay involved! People get jobs via Twitter connections!— Michael Koontz (@_mikoontz) September 24, 2015
The second item on the list is something which I wrote about recently.
