The Bowman Lab

My research interests include developing new methods for crystallization of biomolecules, new methods for detection of nanocrystals, and new methods for in situ X-ray data collection. My research lab is interested in developing new methods that combine crystallographic and spectroscopic approaches to answer fundamental questions about protein biochemistry, especially in proteins that contain metals. We are working to develop spectroscopic methods for single crystals (electron paramagnetic resonance, UV-visible microspectrophotometry, and energy dispersive X-ray spectroscopy for elemental analysis) to be used in parallel with crystallography.

At the Crystallization Center, we provide high-throughput screening for biomolecules to determine initial crystallization conditions, working with scientists around the world (

Software and scripting developed in the Bowman Lab are available on GitHub.


Our commitment to diversity

The Bowman Lab welcomes members regardless of race, religion, gender identification, sexual orientation, age, or disability status.

Student News!

Congratulations to Ethan!

Ethan presented his poster at the 2020 SSRL/LCLS Users’ Meeting and received a poster award!  

Good luck in grad school Ethan!

Ethan did a fantastic job with a new GUI for MARCO automated classification of crystal images!  Beta version will be available soon.  He is on his way to graduate school at UC Davis!
