Benjamin Caplins (Fed)

Research Chemist

I am an experimental physical chemist with experience in time-resolved electron spectroscopy, time-resolved laser spectroscopy, and scanning electron microscopy.  I am currently working on the extreme atom probe tomography project.  I am happy to discuss my published/ongoing works or talk about possible future collaborations.  Please don't hesitate to contact me via email.
