PhD topics and outlines

Biophysical modelling of nanoparticle-enhanced infrared neural stimulation : In visually impaired people who have lost photoreceptors, a sensation of light can be elicited by stimulating surviving retinal ganglion cells (RGCs).  Optical stimulation techniques have been shown to achieve significant improvements in the stimulus resolution and inhibition of RGCs.   The aim of this project is to build biophysical models of nanoparticle-enhanced infrared stimulation of RGCs.    

Deep reinforcement learning for human-centric guidance in AR/VR: A branch of machine learning called deep reinforcement learning has recently outperformed human experts on tasks such as playing Atari games and the traditional Chinese game Go. In this project, we seek a student to research and develop a deep reinforcement-learning framework for learning task-specific visual enhancement filters, and from this, novel scene visualisations to guide human activity. 

Functional role of beta band frequency oscillations in humans: The field of brain-machine interfaces rapidly grows. New neural decoding algorithms are proposed to control a robotic arm or a wheel chair. Recorded power in beta oscillations (10-45 Hz)  may be used to detect the patient’s attention and readiness to make a movement; therefore, enhancing the existing decoding algorithms.  The project would suit someone with an interest in signal processing. 

Gender and stature identification using image processing and machine learning algorithms: Footprints are unique characteristics of a person and differ in shape, pattern, margin,  and toe marks. In this project, the student will collect data and then develop a machine learning algorithm for automatic identification of gender, age, height and weight of a person from their footprints.

Identifying brain pathways regulating sympathetic nervous outflow: Hypertension is a major cause of death and disability from stroke and dementia.  Specific brain regions drive the excess sympathetic outflow in the various forms of hypertension. The student will analyse brain signals and sympathetic nervous outflow collected simultaneously, using magnetoencephalography (MEG) and muscle sympathetic nerve activity (MSNA) techniques.

Investigation of the effects of electrical and light stimulation on neural response: Electrical stimulation has been used to restore sensory functions in people who lost their vision or hearing.   A novel way to stimulate neurons is to combine conventional electrical stimulation with targeted optical stimulation.  The aim of this project is to explore the effects of electrical and light stimulation on neural responses in experiments and in computer simulations. 

Nanoparticle enhanced infrared neural stimulation of retinal ganglion cells: In this project, the student will  study  experimentally how retinal ganglion cells respond to combined optical and electrical stimulation, when in vitro bath is enriched with gold nanoparticles. 

Seizure forecasting: Electroencephalography (EEG) is often used to predict a seizure, with varying success between participants. There is an increasing interest to use non-EEG body signals, including electrocardiogram (ECG) to help with seizures detection and prediction.  The aim of this project is to use advanced signal processing to forecast seizures from EEG and ECG data recorded by Seer Medical. 

Using machine learning techniques to explore differences in physiology between people with syncope and healthy controls: Syncope occurs as temporary loss of consciousness caused by a fall in blood pressure. To develop an appropriate treatment for the condition, it is important to understand underlying physiology of syncope. The aim of the project is to use machine learning techniques to explore differences in physiological signals between people with syncope and healthy controls.
