Keith Weninger


University Faculty Scholar

Riddick Hall 144



Professor Weninger received his PhD in 1997 from the University of California at Los Angeles (UCLA). After postdoctoral appointments at UCLA (1997-2000) and Stanford University (2000-2004), he joined the faculty of North Carolina State University in 2004 as an assistant professor.

Research Description

Professor Weninger develops single molecule fluorescence methods and applies them to study biomolecular systems. In particular, his lab uses single molecule fluorescence resonance energy transfer (FRET) to characterize the conformational dynamics of multimeric protein complexes. Specific topics of interest include DNA mismatch repair and intrinsically disordered proteins.

Honors and Awards

  • He received the Career Award at the Scientific Interface for his work in biophysics from the Burroughs Wellcome Fund.
