About Us

The CEGR is composed of ten laboratories with over 70 students and staff. We aim to provide a conducive learning environment for making cutting edge discoveries on fundamental mechanisms of eukaryotic gene regulation. Most labs share common space to promote a community of interactions.

Academic Environment

The research interests of all CEGR members are focused on understanding the mechanisms of gene regulation, although each member brings unique perspectives and expertise. The members of the Center for Eukaryotic Gene Regulation include:


    Lu Bai Ph.D. Single cell and single molecule studies of chromatin and gene regulation
   Associate Professor of Biochemistry and Molecular Biology
  Associate Professor of Physics


   David Gilmour Ph.D. Transcriptional regulation of the hsp70 heat shock gene in Drosophila
   Professor of Molecular and Cell Biology and
   Graduate Education Co-Director


   Ross Hardison Ph.D. Genomics and gene regulation
   T. Ming Chu Professor of Biochemistry and Molecular Biology


   Manuel Llinás Ph.D. — Gene regulation in Plasmodium
   Professor of Biochemistry and Molecular Biology


   Shaun Mahony Ph.D. Computational biology and regulatory genomics
   Assistant Professor of Biochemistry & Molecular Biology


   B. Franklin Pugh Ph.D. Biochemistry and genomics and eukaryotic transcription regulation
   Evan Pugh University Professor

   Professor of Biochemistry and Molecular Biology


   Joseph Reese Ph.D.Chromatin structure and gene expression, DNA damage resistance pathways
   Professor of Biochemistry and Molecular Biology


   Scott Showalter Ph.D. — Biophysical chemistry of regulated gene expression
   Associate Professor of Chemistry
   Associate Professor of Biochemistry and Molecular Biology


   Song Tan Ph.D.Structural biology of eukaryotic chromatin and gene regulatory proteins

   Yanming Wang Ph.D. — Epigenetic histone modifications in cell differentiation and cancer
   Associate Professor of Biochemistry and Molecular Biology


Many CEGR members are located in newly renovated adjoining laboratories on the 4th floor of the North and South Frear buildings. All attend a weekly CEGR research forum (held continuously at Penn State since 1989) where the latest scientific work of our graduate students and postdocs are shared and discussed. The CEGR also hosts international summer symposia on chromatin every four years.  Our most recent symposia occurred in July 2015 and July 2011, attracting approximately 300 participants each time. This closely collaborative research center is therefore a unique and productive environment in which to study the mechanisms of gene regulation.


The Department of Biochemistry and Molecular Biology at Penn State is well known as a center of excellence in genomics research and the development of high-throughput experimental assays and associated computational analysis systems. Other relevant faculty in the department include Prof. Anton Nekrutenko (developer of the Galaxy system for processing experimental data online), and Dr. Paul Medvedev (genome assembly).
