@mphendricks.bsky.social, Michael Campos & the rest of Jon Owen's lab were some of the greatest WANDA users of all time. They took LBNL by storm with boxes of distilled solvents and custom precursors.
They showed that robots are pointless if the other parts of your workflow are not reproducible.

Working with WANDA (and Emory!) was one of the highlights of my PhD, and I’m looking forward to my group returning someday to take advantage of these amazing tools. Also excited for the Automating Chemical Laboratories Scialog conference this week to think about how the field moves into the future!
I can't believe it's been 15 years since this paper came out! We introduced a nanocrystal-synthesizing robot called WANDA to the world! Now robots & ML are all the rage, but WANDA was a pioneer & is still going strong. @deliamilliron.bsky.social @molecularfoundry.lbl.gov
