Information for LBNL visitors: If you are visiting me, we should have entered your information in the access system and you should have received email confirmation when approved. If you haven't received it, please let me know at least 24h before your visit. You'll need the email (on the phone is fine), together with a Government ID to get into the LBNL site. The easiest way to get to the site from the BART station or UC Berkeley is to take the "Blue uphill" free shuttle. You can get off at the Building 65 stop and ask for directions to Building 50 (it will be just above you). Alternatively it's a short but steep walk from the UC Berkeley campus. Most of us are on the 5th floor of Building 50. My office (50A-5104C) is within the "Jackson interaction area" in the northern wing of building 50 (building 50A). A nice map of LBL is here: https://map.lbl.gov/.
