Richie worked on polymeric nanoparticle delivery systems for drug and gene delivery during his undergraduate studies at Johns Hopkins University and subsequently at A*STAR’s Institute of Bioengineering and Nanotechnology. His Masters thesis at the Massachusetts Institute of Technology involved the use of self-assembling cyclic peptide nanotubes in the development of soft composite materials. He pursued his PhD studies at the Wyss Institute for Biologically Inspired Engineering at Harvard University, where he worked in the field of engineered living materials, applying the tools of synthetic biology to programme bacteria to produce protein-based materials for bioremediation.

Richie then spent several years at A*STAR’s Bioprocessing Technology Institute getting acquainted with the manufacturing of various biotherapeutic modalities, including biologics, viral vectors, engineered immune cells and nucleic acids. As part of the microbial bioprocessing team, he devised strategies to improve protein production in bacteria, including the manufacturing of growth factors for cultivated meat. He also developed a mucosal delivery platform for biologics by leveraging protein surface display on lactic acid bacteria.

At Davies Collison Cave, Richie handles the preparation and prosecution of patent applications in various areas of life science, biotechnology, medical devices and food technology.
