I consult with a variety of research groups on all types of instrumental methods that are utilized to solve chemical problems. While I specialize in NMR spectroscopy, I am fundamentally a problem solver, and I frequently suggest different techniques if they are appropriate. I am also a resource for safety in the laboratory.
