Toolchain fragmentation: why imaging, culture, and data systems need to talk to each other
Why TechBio Fails Paul De Sousa 5/6/26 Why TechBio Fails Paul De Sousa 5/6/26

Toolchain fragmentation: why imaging, culture, and data systems need to talk to each other

Imaging, culture, data, and automation systems built in isolation. Manual workflows dominate. Why poor integration limits adoption beyond expert labs.
