Welcome to the Ritchie Group website!


We apply optical techniques to explore and exploit the way light interacts with matter. Our experiments include spectroscopic analysis of gases, photolysis, and reaction dynamics, as well as manipulation of colloidal systems using optical tweezers.


We are delighted to welcome Dr. James Fletcher, our newest post-doctoral research associate.

Congratulations to Dr. James Kirkbride on passing his viva!

The Ritchie Group is growing! A warm welcome to our newest recruits: Tomas, Nick, and Terry!
