Since its inception, SFI has prioritized people over programs. Even before the Institute’s official founding in 1984, George Cowan and collaborators envisioned an institute without departments, with renowned scholars as its faculty.

“It was all about really good people who were crossing disciplines,” SFI co-founder David Pines once said.

In keeping with this vision, SFI extends and refreshes its network of researchers annually when it appoints new external faculty, affiliated with universities and institutions from around the world. 

This year, we welcome four new researchers.
