Extreme Vision: Ultimate Designs in Animal Optics

点击翻译按钮获取中文摘要

Vision is the most fundamental of the senses, and it is exciting to imagine how the world appears to other animals. Imagine what seeing in 4 colours looks like? Whilst we understand some of the incredible visual abilities animals possess, such as ultra-violet vision or using mirrors instead of a lens, there are some remarkable visual adaptations that remain unsolved. The aim of my research is to discover the basis of some extraordinary unexplained visual capabilities in the animal kingdom. This is an important area of biology. Understanding how animals view and interact with their world is of elemental significance. Also, discovering the underlying principles behind such unusual capabilities has often led to new breakthroughs in technology. For example, learning how lobsters use reflecting mirrors in their eyes inspired new designs for telescopes. Ultimately, how properties of cells influence animal behavior is of great importance. In my proposed fellowship, I want to focus on the following two areas of vision research, which I believe are both timely and important and also compliment my research skills. Vision in the depths of the ocean is intriguing. In addition to the extreme cold and huge pressure, sunlight only penetrates to a quarter of the average ocean depth and the only usable light is bioluminescence. Many animals have evolved incredibly complex eyes to cope with this harsh physical and visual environment. However, we do not understand how such conditions affect vision in deep sea animals. I will be the first to understand this, by discovering how the light sensitive cells in deep sea eyes truly function when placed under real extreme temperatures and pressures. This work will provide us with a complete and unprecedented understanding into this important area of animal vision. The second theme in my research will examine the reasons behind a sensational new discovery. Recently, an animal called a mantis shrimp was shown to possess a cell within its eye that can precisely manipulate light far better than any man-made optics. However, how the cell does this remains a mystery. Some preliminary work I have done suggests how a combination of the cells structure and optical properties could be responsible for this capability. I will completely solve this problem and drive a new direction in animal vision research. I not only have both the proven expertise and skills to accomplish this goal, but I also already have existing working collaborations with Prof. Justin Marshall, UQ, Aus and Prof. Thomas Cronin, UMBC, USA. They were the principal investigators in the original discovery and such international support in this project will help ensure its success and high impact. Another important part of this work is its relevance to industrial applications. Such an efficient, man-made optical device does not currently exist but could be hugely beneficial to a range of scientific research. Discovering this mechanism would be of considerable interest to many optical scientists. In summary, the requested fellowship would allow me to discover some of the exciting, true visual capabilities of life in the largest and most diverse habitat on Earth.
