Revisitation and biologists
Heavy web users
Go from on website to another
to analyse data
Use a lot of online forms, and
copy/paste to transfer data
Bookmarks and history helpful
but not enough

Preliminary Study of Biologists
20 biologists / bio-informaticians interviewed
Strong habits:
smooth integration in their workflow
Exploratory navigation:
interaction
Redundancy:
need to manage different versions of the same data
Data flows:
copy/paste to chain steps
