Organic Photochemistry and Opto-Electronics

A second aspect of my research focuses on the development of new materials for opto-electronic devices. Organic materials are suitable for applications in organic field-effect transistors. We investigate how the isomeric structure of a material is correlated to the electronic and optical properties. Our strategy is to use target-oriented organic synthesis to prepare an isomer-pure family of new materials and characterize the compounds in collaboration with the Wright Photoscience Laboratory, which provides testing equipment and resources. Our efforts are supported by theoretical studies and actual device characterizations.

To further our understanding of how these new polyaromatic heterocycles interact with light, we also partner with the Ohio Laboratory for Kinetic Spectrometry. Using the vast array of time-resolved spectrometers, we study the interesting excited-state properties of our compounds.

Being a student at the Center has far exceeded my expectations. What is most important for me is the nurturing and intellectually challenging environment, which I found at the Center. Our dynamic faculty members provide the training ground to develop new ideas and to test these ideas in the facilities available at the Center. Furthermore, I have worked hard and earned three years of the McMaster fellowship. The most significant impact this fellowship had on my professional development was to provide me the funding and time to concentrate on my research. Second, the financial support allowed me to travel to conferences and meet fellow researchers as well as to visit our collaborators from other universities. Overall, the McMaster fellowship gave me the chance to develop my identity as a researcher.

As I am getting closer to graduation day, I am thinking about what I will do afterward. I would like to pursue post-doctoral studies to expand my research experience and obtain training in yet another field under the umbrella of photosciences.

My advice to young students is to get a strong background in physics, math and chemistry.
