Graduate Students
R. Aaron Vogt
- R. Aaron Vogt is a graduate student studying the photo dynamics of nitro poly-cyclic aromatic hydrocarbons in solution. His research concentrates on unraveling the photophysical properties of nitronaphthalene derivatives and quantifying their transformation rates. Aaron earned his B.S. in biochemistry and began graduate school at Eastern Michigan University before moving to CWRU in August of 2007.

Nicholas Dunn
- Nick joined the group in 2011.

Nicholas Dunn
Marvin Pollum
- Marvin’s research focuses on DNA-based photonic biomaterials. Primarily, he investigates energy transfer between fluorophores covalently attached to DNA; with the ultimate goal of implementing these DNA-fluorophore constructs in photonic or optoelectronic devices.
- Prior to graduate work at CWRU, Marvin received his B.S. in Biochemistry from Saginaw Valley State University. His other interests include cooking, camping, music, and sculpture.
