It's a bit hard to tell if he'll like it, but maybe try him on the James S A Corey "Expanse" series. If you're prepared to stretch the "reasonably believable in scientific fact" side of things, Scalzi's "Old Man's War" series might be worth a go also. Does he like short stories? If so, Jonathan Strahan's "Infinity" series of anthologies might be up his alley. Other authors to consider include Alastair Reynolds, Greg Egan, Ted Chiang, Nancy Kress.
