I'm currently contributing toward the Rosetta@home (hackers.town team) projects on the BOINC network as well as Folding@Home (hackers.town team) - both projects are currently working on protein folding for COVID-19.

Of course, like all geeks, I cut my teeth by contributing to SETI@home in the past, when it was still in operation, as user 9680590 (I don't have a record of my pre-BOINC contributions).
