I am an international PhD student at Adelaide University in the School of Biological Sciences. My research focuses on mechanoreception in marine and terrestrial snakes, and more specifically on how this sense relates to ecology and evolution. To explore this, I am employing behavioural and physiological methods, as well as various microscopy and imaging techniques.
I completed my master’s in the IMBRSea program (International Master of Science in Marine Biological Resources), part of the Erasmus Mundus Joint Masters. For this program I visited the University of the Algarve in Portugal, the Marche Polytechnic University in Italy, Harvard University in the United States of America, the Tjärnö Marine Laboratory (University of Gothenburg) in Sweden, the University of Western Brittany in France as well as La Trobe University and the University of Adelaide in Australia. My master’s thesis was conducted in both Universities in Australia under the guidance of Jenna Crowe-Riddell and Shaun Collin and focused on mechanoreception in Hydrophis sea snakes and how it related to ecological adaptation. I had the opportunity to join a Field Expedition to Broome (WA) and have worked with the collections of the South Australian Museum and the Western Australian Museum.
I was then offered a six-month fellowship by Peter Girguis to work in the Girguis Lab at Harvard University. I developed molecular assays for enzyme detection in deep sea clams and mussels with Andrea Unzueta Martinez.
I have since returned to Australia, to start my PhD at Adelaide University and build on my master’s thesis to explore mechanoreception more in depth and from different angles. My supervisors are Jenna Crowe-Riddell, Kate Sanders and Shaun Collin.
My research focuses on mechanoreception in terrestrial and marine snakes. I want to investigate if the shape and distribution of mechanoreceptors can tell us anything about the ecology of the snake being examined, in hopes of developing an identification tool which can then be used for rare species where little is known about their ecology to get some insights without harming the animal. This part of my research employs non-destructive 3D surface imaging of the skin.
I also want to look more in detail at the receptors and want to find out what happens to them during development, is there are different receptor types and how sensitive they are to stimulus such as vibration or water motion. This part of my research employs various microscopy techniques as well as some physiological and behavioural.
My final goal is to examine the neuroanatomy of sea snakes to try and determine how important mechanoreception is compared to other senses. To do this, I’ll be looking at the nerves and associated brain regions of sea snakes. This part of my research employs imaging and microscopy techniques.
This project has benefits for conservation as it may uncover much information on sea snake ecology and on their vulnerability to vibration in the water. It will also look into ecological or evolutionary drivers for the development and diversification of mechanoreception across snake lineages, and thus give us further insight on snake evolution and diversification.
