Rachel is the co-inventor of an optical sensor platform technology that is currently being commercialised through Senoptica Technologies. Senoptica is a spin-out company co-founded by Rachel while at Trinity College Dublin.

The patent-pending Senoptica technology monitors the gas content in modified atmosphere food packing in conjunction with state-of-the-art imaging technology. This enables each and every food package to be monitored and tracked in real time, leading to improved compliance, increased self-lives and reduced food waste.

Initial funding for proof-of-concept research was awarded to Rachel by Enterprise Ireland. Read more about the Senoptica story here.
