Catherine Royer

Constellation Chair


Dr. Royer obtained her Bachelors (Licence) degree in 1979 at the University of Pierre and Marie Curie - Paris 6 in Biochemistry and Chemistry. She obtained her Ph.D. in 1985 in the Department of Biochemistry in the School of Chemical Sciences at the University of Illinois at Urbana-Champaign under the direction of Professor Gregorio Weber. She carried out postdoctoral studies at the University of Paris 7, the CNRS at Gif-sur-Yvette and at LURE under the direction of Bernard Alpert, Guy Hervé and Jean-Claude Brochon. She then took a position as User Coordinator and Research Physicist at the Laboratory for Fluorescence Dynamics in the Department of Physics at the University of Illinois - Urbana Champaign. In 1990 she moved to an Assistant Professorship in the School of Pharmacy at the University of Wisconsin-Madison, where she was promoted to Associate Professor with tenure in 1995. In 1997 she took the position of INSERM Director of Research in the Center for Structural Biochemistry in Montpellier France where, in 2002, she became Associate Director of the institute and in 2007, Director. In 2013 She moved to Rensselaer Polytechnic Institute as a Professor of Biological Sciences and chaired Constellation Professor in Bioinformatics and Biocomputation.

My research aims at understanding the molecular basis for biological function in two main areas. The first involves understanding how amino acid sequence controls protein structural dynamics using pressure perturbation combined with state-of-the-art biophysical techniques. This is important information for protein design strategies for bio-pharmaceutics and for bio-engineering applications, as well as for understanding the evolution of protein sequences and life in extreme environments. The second area of research that I pursue involves characterizing, quantitatively, the protein interactions implicated in the regulation of gene expression. Currently we are trying to understand the links between cell growth and division in the model organism, budding yeast by applying advanced quantitative microscopy approaches. Understanding what drives cells to divide is important for understanding and developing therapeutic strategies for the treatment of many diseases, including cancer.

Primary Research Focus
Sequence determinants of biomolecular conformational landscapes; Molecular mechanisms of transcriptional regulation
Other Focus Areas

Pressure effects on biomolecules, protein folding, protein interaction networks, live cell quantitative fluorescence imaging, transcription regulation, molecular evolution

Current Courses

BCBP 4800/6800 - Methods in Biophysics 

Biophysics addresses the physical principles of biological function, which requires the application of physical methods. The focus of this course is on methods used to study the interactions and dynamics of biomolecules in vitro, primarily proteins and nucleic acids. Both the theoretical and methodological aspects of molecular biophysical methods will be covered. This course is designed as an interdisciplinary introduction to the field and is open to students in biology, chemistry, physics, or engineering.
