Chromatin and Regulation of Gene Expression

Research includes:

  • Biochemistry
  • Chromatin
  • DNA Repair
  • Gene Expression
  • Genomics
  • Nucleic Acids
  • Transcription

Training Group Mission:

Students in this training group work with a diverse group of faculty who employ an extensive range of experimental approaches with the goal of understanding chromatin and regulation of eukaryotic gene expression. Recent advances in the identification of chromatin modifying proteins and in the elaboration of the “histone code hypothesis” illustrate the value of interdisciplinary approaches in gaining insights into this exciting area of research. Students also have the opportunity to examine the effect of chromatin on other DNA-based processes such as replication, recombination, and repair. All students receive broad training in genetic, biochemical, and genome-based approaches in analysis of these fundamental processes.

Aging photoreceptors in the eye show characteristic changes in gene expression. Our lab is interested in understanding the mechanisms that drive these changes in gene expression. These studies provide a model for understanding how aging contributes to ocular diseases such as age-related macular degeneration. Our work is funded by the National Eye Institute of the NIH. We are actively seeking new graduate students, so please contact us if you are interested in joining our group.

Maize genetics, genomics, value-added traits
Signal transduction in cancer biology, early neuronal development and cancer metabolism.
