Cell Processing Expertise

Matt Seefeldt, Ph.D.


  • Eighteen years of experience in biotechnology manufacturing, with an emphasis on translating early-stage therapeutics into the clinic.
  • Developed six IND-enabling cGMP processes on both microbial derived proteins and cell therapy products. One of those products was successfully scaled to support Phase III clinical studies.
  • Successfully completed the build out and GMP preparation of the Gates Biomanufacturing Facility .
  • Considered a world expert in protein refolding
  • Expert in protein stability and formulation, with specific understanding of the link between aggregates and immunogenicity

Cell Therapy Process Development Laboratory

  • Equipment mirrors cGMP cell processing equipment for seamless process transfer – 1:1 scale
