Educational Background



Dr. Dilbeck received his B.S. in Cell and Molecular Biology from Oklahoma State University in 2006 and his Ph.D. in Microbiology, Cell and Molecular Biology from Oklahoma State University in 2012. Dr. Dilbeck joined the Holten group in 2012.

Research Interests



Dr. Dilbeck is studying energy transfer in native and mutant light-harvesting systems LH1 and LH2 from purple photosynthetic bacteria and relating the results biohybrid antenna systems.
