My Focus

I am a PhD candidate in the Porter lab at the University of Hawai'i at Manoa, in Honolulu, HI, USA.  Light encodes a wealth of information for animals equipped to detect it. I am broadly interested in how animals produce light and also how they detect it.

 

Bioluminescence has evolved more than 40 times across animal taxa. It is used for offence, defence, and communication. Generally speaking, the bioluminescent reaction involves the oxidation of a luciferin molecule catalyzed by a luciferase protein. My focal species are oplophorid shrimp and Pleuromamma copepods.

 

The fundamental molecular unit of vision is the opsin, a gene that encodes a light-sensitive protein found in the retina. Humans perceive light through four visual opsins; one rod opsin and three cone opsins. Human colour vision is facilitated by the interaction between those three spectrally distinct cone opsins. In contrast, many non-human animals may have 1 to 10 or more visual opsins.

 

My research aims to discover the broader function and evolution of opsin and luciferase genes by connecting molecular biology and animal behaviour.
