Research/Professional Interests

The Koch group is focused on the design and synthesis of new compounds that aid in the preparation of other molecules.  Essentially we design and make things that provide others with new tools to prepare organic molecules needed for other purposes such as pharmacueticals and materials.

We are currently working on compounds that can incorporate nucleophiles into electron-rich aromatics, the preparation of catalyst and co-catalyst systems for oxidation using molecular oxygen, and some specific student-designed projects.
