Please forward to anyone that might be interested. Thanks!
Early Stage Researcher (PhD student) in optics of myopia
We invite applications for an Early Stage Researcher (PhD) position
being part of the Marie Sk?odowska Curie European Training Network
'Myopia: Fundamental Understanding Needed' (MyFUN). Topic of the
project: We investigate the impact of the eye's optics in relation to
myopia. The project is a three year PhD designing and developing an
optical instruments to study ocular accommodation and how this relates
with myopia. The successful candidate will learn about design and
technology of medical instrumentation. He/She will also be involved in
the acquisition of data collection, processing and presenting it. Part
of the time is allocated for networking and the development of important
skills. The candidate will integrate in dynamic University lab but also
will interact closely with an international network of academic and
industrial partners of the consortium. LOUM is a world-leader research
lab in biomedical and visual optics directed by Prof. Artal.
Optics of ocular accommodation and myopia
A big question remains as to why myopia progression is only loosely
correlated to near work. Not all epidemiological studies could
demonstrate a link. The problem arises perhaps because it is still not
known what exactly triggers myopia during reading. A classical theory is
that accommodation is insufficient ("lag of accommodation") but the
published studies could not convincingly demonstrate that a lag of
accommodation precedes the onset of myopia, and the evidence that myopic
subjects have larger lags of accommodation is mixed. A major problem is
the technologies used to measure the lag of accommodation. First, the
devices are typically optimized to measure the best approach to the
spectacle refractions (but generating large offsets at near) and second
only few studies have taken higher order aberrations into account even
though they also determine the plane of best focus. Therefore, a
dynamic, binocular aberrometer that can also track pupil size and
vergence will be the only approach to finally determine how big the "lag
of accommodation" is during binocular reading and whether it might be
related to the defocus error signal driving accommodation. The device
consists of a single Hartmann-Shack wavefront sensor conjugated with
both eyes' pupil planes through twin periscopes for simultaneous
measurements of the dynamics of accommodation, aberrations, pupil sizes
and convergence (Chirre et al, Opt Lett 2014, 39). A dichroic mirror
transmits the visible light allowing open-view to the subject while the
infrared beams are reflected toward the sensor positioned in a lower
plane. From the recorded images, both eyes` wave-aberrations, pupil size
and relative convergence can be measured in real time (25 Hz).
·MSc or equivalent degree in physics, engineering or related discipline
which allows to start a doctorate
or PhD thesis
·Has a desire to learn and innovate.
* High level of written and verbal English is fundamental. Spanish is
not a requirement.
The EU has strict eligibility criteria for Early Stage Researchers:
·Must not have resided or carried out their main activity in the country
of the host institution (Spain) for more than 12 months in the 3 years
immediately prior to their recruitment.
·Should not possess a PhD
·Should have less than 4 years of research experience. This is measured
from the date when they obtained the degree which formally entitles them
to embark on a doctorate, either in the country in which the degree was
obtained or in the country in which the research training is provided.
