Timothy Peelen

Associate Professor of Chemistry

Email: peelen@lvc.edu

Phone: 717-867-6147

Office Location: Neidig-Garber 426

Expertise:
Organic Chemistry

Research & Practice Areas:
We use the tools of organic chemistry to investigate several questions: to develop new chemical reactions, to prepare molecules that can be applied as new ligands for metals with light-absorbing and light-emitting properties, and to study the interactions between chiral, “handed” molecules.
