Bioprocess Measurements Group

The Bioprocess Measurements Group develops measurement methods and standards that support a variety of application areas, particularly those relevant to biological industrial processes.

Areas of current active interest include:

  • Standards and new methods for counting and characterizing protein particles in biotherapeutics
  • Novel sensors for monitoring health and industrial manufacture of biological products
  • Innovative device platforms and signal processing methods
  • Affinity-based assays of the glycosylation (sugar decoration) patterns in biotherapeutic proteins
  • Protein conformation studies, in solution and adsorbed to surfaces.

We combine expertise in instrumentation science, nanomaterials, and chemical and physical characterization of surfaces, sensor materials, and biological molecules.
