Our research questions are centred on a basic characteristic of biological systems: noise, uncertainty or variability in behaviour. Variability can be observed across many levels of biological behaviour: from the movements of our limbs, the responses of neurons in our brain, to the interaction of biomolecules. Such variability is emerging as a key ingredient in understanding biological principles (Faisal, Selen & Wolpert, 2008, Nature Rev Neurosci) and yet lacks adequate quantitative and computational methods for description and analysis. Crucially, we find that biological and behavioural variability contains important information that our brain and our technology can make us of (instead of just averaging it away): The brain knows about variability and uncertainty and it is linked to its own computations. Therefore, we use and develop statistical machine learning techniques, to predict behaviour and analyse data.
Our cross-disciplinary outlook is reflected by us being part of the Dept. of Bioengineering & Dept. of Computing (South Kensington Campus) and the MRC Clinical Sciences Centre (Hammersmith Hospital Campus). Our team and lab facilities are housed centrally inside Bioengineering at the Royal School of Mines Building on Prince Consort Rd (strategically next to the Natural History Museum and Hyde Park, see map here).
We seek a Post-Doctoral Research Associate for a 2 year Human Frontiers in Science funded project. We are seeking candidates with experience in computational neuroscience/cognitive neuroscience/psychophysics/machine learning. Applicants should have (or soon to be awarded) a Ph.D. in a discipline relevant to the project and publications in high-quality journals. Informal enquiries may be addressed to Dr A Aldo Faisal, email@example.com.
A 45 minute discussion on BBC's The Forum: Are computers now so adept at handling previously unimaginable amounts of data that a meaningful partnership can open between human and computer brain? In this week's Forum Carrie Gracie discusses the shared journey ahead with Aldo Faisal, a neurotechnologist bringing engineering expertise to the study of the human brain and vice-versa; Larry Norton, a cancer specialist harnessing a supercomputer to diagnosis and treatment; and statistician Patrick Wolfe trying to keep humans on top in a world of dizzying digital data.
The whole thing runs every day from the 4th to the 14th of April 2013 - see the Web site or Facebook. It's is of course free for the public and very family friendly with activities and cafe. "We" being the MRC CSC design company Haberdashery and Will, Anastasia, Andreas and others from our lab with Aldo as scientific co-director.
We were awarded the prestigious Human Frontiers in Science Program Grant (1.05 Million USD, 2% success chance) by HFSP. In close collaboration with Michael H. Dickinson's Lab at the University of Washington (Seattle) and Carlos Ribeiro's Lab at the Champaliamaud Neuroscience Program (Lisbon) we will work on Value-based decision making in Drosophila foraging: genes, computations and behaviour.
Our aim is to understand from the level of genes and neurons the neural computations involved in neuroeconomic decision making in an evolutionary fundamental behaviour: foraging in the genetic model organism Drosophila melanogaster (the famous fruit fly). The lab is now seeking a suitably qualified PostDoc with a strong publication profile.
We reiterated this message again at the TEDx Imperial event on 23rd March 2012 - concluding with the message on our goal of Frugal Innovation: Frugal engineering is achieving more with fewer resources.
We published this work in a series of papers starting with Faisal et al. (2005, Current Biology, PDF), Faisal & Laughlin (2007, PLOS Comp. Biol., PDF) and in a bigger context of Noise in the Nervous System in Faisal et al. (2008, Nature Reviews Neuroscience, PDF).
Our study, the fruit of an exciting collaboration with neuro-archeologist Dietrich Stout (Emory University) and experimental archeologists Bruce Bradley (flintknapper on our video) and Jan Apel just appeared in PLoS One (here) - generating some Media Buzz, including an interview on the BBC 4 Today Show and the print media (details here). Note, the neuroimaging data was collected previously by our co-author Dietrich Stout and Thierry Chaminade.
Key enabler for this study (and the field of experimental archeology) was our development of quantitative techniques to quantify thedexterity required to manufacture stone age tools from experimental data. Our techniques are based on motor psychophysics (data gloves, motion tracking) to record the manufacturing process of flint stone toolmaking. This was analysed using a novel and objective method (based on data mining algorithms) to compare the complexity of human hand, arm and body movements. As such our novel technique can be applied to anywhere we want to measure and compare motor/dexterity requirements from rehabilitation medicine to product design - true Neurotechnology. This forms part our research program to develop a “Bioinformatics of Behaviour” for the automated annotation and analysis of behaviour.
Our ultra-low cost Neurotechnology system (GT3D) enabled the first video game for paralysed people. We developed a 3D eye tracking system (at roughly 1/1000 of the cost of comparable commercial system, or less then 50 USD) and a human-computer user interface solution for heavily impaired people. The result of two projects in the Lab which produced the first video game for movement impaired or paralysed people. This generated some media buzz, being picked up by the The Sun, The Times of India and Engadget. More about it here.
