Welcome to my new web site. I am transitioning between web servers, consequently this new version of my site is slowly rolling out. I should be fully up and running here before September, 2015. In the meantime, my old site will be running for a little longer at http://chemistry.che.depaul.edu/rniedzie

I have been teaching a variety of different courses at DePaul since 1998. My primary research interests lie in the area of optical properties of materials thought to be components (or proxies) of aerosols found in the troposaphere. Please use the tabs to navigate through the site.
