Welcome to the Tomko Lab
Destroying stuff to fix people!
Diversity and Inclusion
The Tomko lab is committed to maintaining a safe and inclusive (and FUN!) environment for everyone — no ifs, ands, or buts. No matter who we are or where we come from, we are united by science, and we believe that diverse skills, viewpoints, and experiences make us stronger.
Scientific research can create enormous energy and material waste. Our group is committed to reducing our impact on Earth's wellbeing by actively minimizing unnecessary energy consumption and use of single-use or disposable items. We also reuse or recycle lab materials whenever this can be safely done.

Robb's first senior-author manuscript is forthcoming in the October 8th issue of Cell. In this manuscript, we identify a single alpha helix that acts like a key in a lock to remodel the assembling proteasome lid subcomplex. This remodeling exposes the binding site for the remainder of the proteasome. Such assembly-coupled conformational switching is reminiscent of the maturation events observed during viral capsid assembly and may represent a conserved mechanistic theme regulating hierarchical assembly of macromolecular structures.
