Co-founder and CEO at Defined Bioscience, Inc


Steven Rees is co-founder and CEO of Defined Bioscience, Inc. He earned his PhD in Biomedical Sciences at the University of California San Diego, with a focus on molecular biophysics. His background centers on protein engineering techniques to produce, purify, and optimize targets over several classes, including membrane transporters, growth factors, G protein-coupled systems, monoclonal single-domain antibodies, and peptides (11 publications, 1 patent filing).

His company, Defined Bioscience, focuses on next-generation ingredients for cell culture, including cell medium formulations, growth factors, and supporting supplements, with applications in life science, pharma, and cell-cultivated meat sectors. Since opening its doors almost three years ago, Defined has launched nearly a dozen products (all animal-free, serum-free, and fully defined) and established partnerships, licensed IP, and secured nearly $3M in non-dilutive funding.
