He served at Louisiana State University (LSU), Baton Rouge, LA, USA, as the first selected Chair for the Louisiana Sea Grant and Technology transfer.

Richard Gordon's involvement with diatoms goes back to 1970 with his capillarity model for their gliding motility, published in the Proceedings of the National Academy of Sciences of the United States of America. He later worked on a diffusion limited aggregation model for diatom morphogenesis, which led to the first paper ever published on diatom nanotechnology in 1988. He organized the first workshop on diatom nanotech in 2003. His other research is on computed tomography algorithms, HIV/AIDS prevention, and embryogenesis.
