Uli Siebeck

I studied Animal Physiology, Plant Physiology and Biochemistry as part of my undergraduate degree at the University of Tübingen in Germany before conducting research for my Diploma (Masters equivalent) at the Max-Planck Institute for Biological Cybernetics (Tübingen). Under the guidance of Nico Troje, Deszö Varju and Heinrich Bülthoff, I studied visual perception (animal and human) and was trained in various psychophysics methodologies.


Amira Parker

I received my bachelor of marine studies at the University of Queensland in 2007 and continued on with post graduate studies, recently completing my PhD in 2015. During my PhD, I looked at Ultraviolet communication in reef fish, focusing on the Ambon damselfish (Pomacentrus amboinensis) and its predator the Yellow dottyback (Pseudochromis fuscus). Using behavioural experiments I characterised the ultraviolet communication channel and modeled the working range of UV signaling in the marine environment for the first time and also determined whether UV serves as a secret communication channel. I am interested in the visual neuroethology of coral reef fish. In particular i am interested in understanding how fish use vision to communicate and interact in their visual complex coral reef habitat. Furthermore, I am interested in how ocean acidification may affect vision and in turn behaviour.

Emmanuel Legorreta

I studied Psychology at the University of Salamanca in Spain and in my last undergraduate year I started my research in the Neurohistology laboratory of Dr. Saldaña, at the Institute of Neuroscience of Castilla y Leon, where we studied the connections of the auditory midbrain. To do so I was trained in neuroanatomical tract-tracing techniques and histological processing of brain tissue. I continued working in this laboratory while doing Masters Degree. After that I did a collaboration with the laboratory of Dr. Tecuapetla in the Institute of Cell Physiology at the UNAM, in Mexico, where I implemented and trained neuroanatomical techniques and collaborate with optogenetic experiments. Finally, I was accepted to do my PhD with Dr. Siebeck at the SBMS. The project will involve the study of cognitive behaviour of reef fishes, its neuronal correlates and how climate change may alter their behaviour. My main research interests are Neuroethology and Neuroanatomy and I am glad that I am able to fulfil those interest here while doing field trips and laboratory research.

Chris Braun

After completing his Diploma thesis on the use of red colour signals in a Mediterranean labrid at the University of Tuebingen, Germany, Chris joined the Siebeck lab in 2011. Having spent some time at UQ as an exchange student and volunteering at Lizard Island Research Station a few years earlier, Chris was keen to get back into the field and work on the Great Barrier Reef. His PhD thesis, “UV-induced DNA damage in coral reef fish: Damage levels and protection mechanisms” was the first to describe the impact of UV radiation on reef fish and to demonstrate that natural sunscreens can protect reef fish from UV damage. Over several field seasons at Lizard Island and lab-based experiments at UQ, Chris also showed that reef fish larvae have the ability to use DNA repair mechanisms to reduce DNA damage caused by UV exposure. Interestingly, one of the main study organisms of the Siebeck lab, the Ambon Damselfish Pomacentrus amboinensis, which has the ability to see UV light and communicates with UV signals, does not actively avoid high levels of UV radiation as previously hypothesized. His findings have opened the door for new research on the use of sunscreens in reef fish and the trade-off between UV communication and UV protection. His work led to a number of presentations at international conferences, a podcast for his funding body, the SeaWorld Research and Rescue Foundation and a collaboration with the Eye on the Reef Program run by GBRMPA . Chris is currently working as a Graduate Ecologist with frc environmental in Cleveland, where he successfully applies his experience in field work, analysing data and report writing.
