*Fully funded PhD Studentships*


The Crabb Lab at City University London provides a lively research
environment with a unique mixture of vision scientists, ophthalmologists,
computer scientists and mathematicians.

For more information: www.staff.city.ac.uk/crabblab

Two full time PhD studentships in data science are now available (October
1st 2016) in this lab focussing on:

*1. Detecting and monitoring glaucoma using eye movement scan paths*

Eye movements (EMs) are the most frequent voluntary action we make in our
waking day, occurring more times per second than our hearts beat. A
predominant EM is the saccade – the quick, ballistic action the eyes make
as they move between fixations. Our overall working hypothesis is
dysfunction in the visual system can turn up in the form of tell-tale
differences in a person’s gaze measured by state-of-the-art eye tracking,
including a novel analysis of patterns of saccades, as a person watches a
film. Glaucoma detection and monitoring is done, mainly inadequately, in a
clinic; a system that is likely unsustainable in the future. Instead of
relying on infrequent tests in a clinic, focus should shift to capturing
vision loss as part of a person’s ordinary daily activities. Our contention
is that anomalies in EMs tracked during viewing of stimuli have the
potential to be developed into a rigorous test that could be incorporated
into an everyday activity, like something as simple as watching a movie.
Our research lab is collecting an archive of EM data in people with and
without glaucoma as they watch different types of movies & footage of
natural scenes and this data is available for analysis in this project. We
therefore seek a creative scientist that can further develop methods to
analyse these data.

*2. Combining imaging and functional measurements in glaucoma*

In clinical practice, the main measurement of vision loss in glaucoma is
done with automated perimetry yielding visual field maps. These maps
exhibit massive measurement variability often meaning delayed
identification of disease deterioration, with a consequence on treatment
outcomes, and the requirement for frequent clinic visits for visual field
examinations, with consequent cost and patient inconvenience. This
programme of work will investigate if combining information from retinal
imaging and conventional visual field measurements accelerate the reliable
identification of vision loss in patients with glaucoma. This programme of
work will adapt and develop statistical models for detecting glaucoma
progression already developed at City University London and will also
incorporate modern statistical methods (feature extraction) for assessing
changes in shapes in the retinal images. The project will take advantage of
huge data sets of measurements taken from clinics and clinical trials. We
seek a creative data scientist who will develop these statistical methods
to potentially provide improved clinical outcomes. The scientist will also
work directly with software engineers at Heidelberg Engineering with the
aim of implementing the methodology on clinically used instruments.

(The City University London projects are #3 and #5)

*The studentships*

Training in software engineering, programming, statistics, biomedical
engineering, computer science (at Masters level). Detailed knowledge about
vision or eyes will not be required, but a flair for creatively analysing
data is essential. Alternatively someone with clinical (biomedical)
expertise and some knowledge/expertise of the above.

Results from this PhD are likely to generate considerable interest and will
lead to presentations at
conferences in the US and Europe; extensive travel funding is available.
The 3-year studentship is worth £25,000 per annum (tax free), with all fees
for PhD registration paid.

*Eligibility*

The EGRET+ program is supported by a Marie Skłodowska-Curie grant.
According to the grant rules, transnational mobility is required for all
PhD positions. *To be eligible for a PhD position, you cannot have resided
or carried out your main activity in the country of the recruiting
institution (in the case of these two studenships, the UK) for more than 12
months during the previous 36 months.* We are only recruiting Early-Stage
Researchers who, at the time of recruitment are in the first four years
(full-time equivalent research experience) of their research careers and
not yet have been awarded a doctoral degree. More about eligibility rules
can be found at: http://egret-plus.eu/phd-positions/eligibility-criteria/
