Our Research Interests


2015 TSRC Workshop Sneffel Highline Hike The Bittner group along with other TSRC participants take a break from talking about organic photovoltaics along a 14 mile hike.


We are primarily interested in the dynamics of molecules in their excited electronic states. We use both computational and theoretical approaches to answer the following questions:

  • Which nuclear motions are responsible for accommodating the energetics of the transition by either absorbing excess energy in an exothermic transition or supplying the energy deficit in an endothermic transition?
  • What is the role of quantum coherence, localization, and relaxation in determining not only the transition rates, but also the transport, and spectroscopic properties of excitonic and charge-transfer states, especially in organic semiconducting systems?
  • How do these effects affect the observed dynamics, material properties, or electronic behavior in systems such as organic light-emitting diodes, photovoltaic cells, and DNA chains.

Information for Incoming Graduate Students

Effective Fall 2014, all PhD students who wish to join my group will agree to take their ORP exam in the Fall of their second year. Note, that this is a higher standard than the Department of Chemistry's current requirement since students will be expected to perform at the same level as if they have an extra year. Students who find this to be unreasonable are free to join other groups with lower standards.

Students interested in joining my group should first complete the exam found by clicking here


'Advice to new Graduate Students:' Your job is to keep me engaged in your research project. I have at least 20 other things on my mind: grant proposals, class, papers, reports, meetings, other students, collaborations, etc… One of these (hopefully) is your Ph.D. project. If that’s not the case, then you need to figure out how to change this situation. I have a PhD…you don’t. I have over 100 publications, your paper won’t affect my career…you need the publication more than I do. Therefore, your job is to keep me up to date with your projects. Your goal as my postdoc or grad student is to have me talk about your work at conferences and meetings. I only talk about the best work coming out of my group. If I’m not talking about YOUR work at meetings, YOU need to change that situation!
