Technical Assistant London
Profile of Thomas Ricketts

I joined D Young & Co in 2016 with a background in molecular biology, genetics and neuroscience. I thoroughly enjoy supporting our innovative clients through utilising my scientific and legal knowledge.

I have experience in drafting, prosecution, opposition, appeal and freedom-to-operate work in a broad range of life science areas. I am particularly experienced in the technical fields of genetics, vaccines, peptides and food technology.

Prior to joining D Young & Co I completed my PhD, followed by working as a post-doctoral researcher for four years at the Cambridge Institute for Medical Research. My research focused on generating and characterising in vivo models of neurodegenerative diseases and the cellular process autophagy.
