Welcome
Welcome to my web site. I am a research fellow at the Queensland Brain Institute and the School of Information Technology and Electrical Engineering at the University of Queensland in Australia. My research interests are robotics, neuroscience, and animal navigation. On this page you'll find links to my research work as well as to my other activities. 
If you have come here from the New Scientist website, I suggest you have a look at our publications. The New Scientist article can be found here.
News23-07-2008 Paper accepted to the journal IEEE Transactions on Robotics for publication in October 2008. The paper will form part of a special issue on Visual SLAM and presents work showing that it is possible to map an entire city suburb using just a low quality web camera mounted on the back of a car. This work follows on from preliminary work in this conference paper. You can see a photo of the experimental setup just below :) 
15-04-2008 London, Norway, and Portugal TripFinally got around to putting up some photos from my overseas trip, just click on the piccie below to open up the gallery. 
07-01-2008 Brisbane City Hall Hollywood New Years BallWent to the ball and decided to actually make an effort with a costume...which of course had to be The Terminator. Here's a couple of pics: 
That's a red LED I soldered some wires to which led down into my pocket where I had two AA batteries in series. Wasn't exactly the most comfortable setup having this hot, spiky thing right next to my eyeball but it was well worth the sacrifice, as it got me a best costume award on the night :) The grenades were foam bells which I cut the bottom of the bell off, and painted gold, with a black cardboard cylinder as the body of the grenade. The ammo belt was made from felt. Leather jacket was from St Vinnies. 13-12-2007 Australasian Conference on Robotics and AutomationPresented a paper at the conference on outdoor mapping and navigation.

15-12-2006 Had my graduation ceremony today, click on the photo to see a few happy snaps.     01-12-2006 Some of the final permanent binding copies of my thesis, others are already enroute to the central University Library and my department. Ran into a few other very relieved students who were handing in their final temporary or permanent binding copies. Only graduation left now.  28-11-2006 Article in the Courier Mail about what life is like as a robotics researcher. I must say one thing: the robots rarely catch fire. 
22-11-2006 Journal paper accepted to the Robotics and Autonomous Systems journal.  21-11-2006 Am OFFICIALLY a doctor now, yay.

Got around to putting up my photos from the 2006 International Conference on Robotics and Automation which was held in Beijing, China. 19-09-2006 2006 Young Achiever Awards
Read the UQ News story here (.pdf reader required).
Just got back from a gala dinner at the Carlton Crest ballroom for the 2006 Queensland Young Achiever Awards, where I was lucky enough to get the Science and Technology Young Achiever Award. Thanks must go to my supervisor Dr Gordon Wyeth for taking me on in the first place for my PhD as well as for being one of my referees. Thanks also to Dean Lane who was my other referee and Terese for nominating me in the first place. And thank you ITEE, UQ, and the ARC for providing me with the resources and support to really get stuck into my research over the past three and a half years. 04-08-2006 
After almost exactly 3.5 years, I've finally submitted my PhD thesis for examination. Yay!
25-07-2006 My two superiors Dr Gordon Wyeth and Prof Janet Wiles (along with a number of other chief investigators) are awarded the Australian Research Council Special Research Initiative Application "Thinking Systems: Navigating Through Real and Conceptual Spaces" Grant, worth $3.3 million over 5 years. Here's the brief description of the project: The project will provide fundamental insights into physical and conceptual spaces and develop applications in robotics and information systems. The project brings together national and international researchers to study how humans and other animals navigate: how trajectories through space are used to build maps, the neural bases of these mapping processes and how to use maps to achieve goals. The project will develop a new generation of robots that can learn about the physical spaces they work in, and create concept-mapping systems that can map and navigate information spaces. Also, it will provide new insights into the mechanisms regulating human cognition and mental dysfunctions. 21-07-2006 
The thesis is almost complete. Final draft has been given to everyone to read, will do corrections based on their comments and then submit. If you're interested in reading any of it, tell me! 30-06-2006 I finally got around to putting up my list of massively overquoted trivia. You know those bits of trivia friends always drop into the conversation one too many times - this is a list of them. Go have a look here. 08-06-2006

Paper accepted to the International Conference on Intelligent Robots and Systems, titled "RatSLAM on the Edge: Revealing a Coherent Representation from an Overloaded Rat Brain". This one contains a heap of information on my most recent work, including the effects of shrinking our artificial rat brain, and also an algorithm that enables the robot to intelligently adapt to changes in an environment. 21-04-2006 What a PhD student gets up to after finishing their first draft and not feeling like getting back onto it straightaway...   19-04-2006 First thesis draft finished and scanned by supervisor. Yay! Only 224 pages and 60,000 words later... 
20-03-2006 Thesis writeup chugging along. Updated progress graph below:  Assuming linear progress (yeah right) I will hit 1000 pages in about seven and a half months :) 24-01-2006 Finally had a chance to let roboraptor loose with some dogs...these videos are the result.

Paper accepted into ICRA 2005 (International Conference on Robotics and Automation) - yay!
My PhD Project
We are trying to use the extensive research that has been carried out on the rodent hippocampus to come up with a biologically inspired system that can be used on a real mobile robot navigating around a large, unmodified indoor environment performing useful tasks. The possible applications of this work are in the short term in the area of mobile robotics whether that be service robots or robots wandering around on the surfaces of other planets. In the long term by furthering our understanding of the true nature of intelligence this work is leading towards truly autonomous robots that have genuine thinking abilities, and in the ultra long term to sentient systems.
The RatSLAM project can be found here. Below are a couple of pictures to give you an idea of what we're doing, one of the Pioneer2 DXe robot we're using and the other of the software interface for our RatSLAM system. We have also done experiments on an outdoor tractor robot from CSIRO.
