We invite interested scholars for short visits to the Spacetime After Quantum Gravity research group, located in the philosophy departments at the University of Illinois at Chicago and the University of Geneva. To facilitate visits we can offer financial assistance for travel and lodging, office facilities, and of course excellent intellectual company. Visits can be from a few days to a few weeks (or possibly longer). Fellowship do not normally cover all expenses.
Details of the fellowship programme and how to apply can be found here.
Taking up Spacetime 
At the age of 76 it is difficult to take fellowships or visits at long distances. However, the internet allows worldwide discussions. For example, ResearchGate allows projects that dedicate to selected subjects. I advise starting such project for quantum gravity after spacetime.
