<h2 class="heading hide-accessible">Summary</h2>

Objects are everywhere, natural and man-made. Advances in technology have led to the routine collection of geometrical information on objects and the study of their shape is more important than ever. Analytically, shape comprises the geometrical information that remains when location, scale and rotational effects are removed from the description of an object.<br /> <br /> In many settings it is possible to define &amp;quot;landmarks&amp;quot; which can be consistently identified across a set of objects, and developments over the past 30 years have led to the new subject of statistical shape analysis, an extension of multivariate analysis. We have pioneered the development of statistical shape methodology for many medical, biological and computational real examples. More details can be found in Dryden, I.L. and Mardia, K.V. (2016) Statistical Shape Analysis with Applications in R, second edition, Wiley. In dynamic shape analysis the shape of an object changes through time.<br /> <br /> The time scale can range from years, e.g. the growth of a human face between childhood and adulthood, down to seconds, e.g. the formation of human facial expressions such as a smile. Such applications can be viewed as multivariate time series, sometimes with change points. It has some methodological connection with our pioneering contribution to growth assessment through facial LASER scans of children.<br /> <br /> The motivating application for this project comes from the use of craniofacial surgery to correct facial deformities such as a cleft lip. One measure of success for the surgery is the ability of the patient to make &amp;quot;normal-looking&amp;quot; facial expressions, such as smile. At the moment this judgement is made subjectively. Using a 3D motion capture camera system, we have already acquired some dynamic data for the normal human smile.<br /> <br /> The aim of the project is to develop and assess more objective measures to quantify the success of surgery, leading to a high impact contribution. Note that no knowledge of shape analysis is necessary.

<h2 class="heading">How to apply</h2>

<p>Formal applications for research degree study should be made online through the&nbsp;<a href="https://www.leeds.ac.uk/info/130206/applying/91/applying_for_research_degrees">University&#39;s website</a>. Please state clearly in the research information section&nbsp;that the research degree you wish to be considered for is &lsquo;Dynamic shape modelling in reconstructive surgery&rsquo; as well as <a href="https://physicalsciences.leeds.ac.uk/staff/59/professor-kanti-mardia">Prof Kanti Mardia</a> as your proposed supervisor.</p> <p>If English is not your first language, you must provide evidence that you meet the University&#39;s minimum English language requirements (below).</p> <p><em>We welcome applications from all suitably-qualified candidates, but UK black and minority ethnic (BME) researchers are currently under-represented in our Postgraduate Research community, and we would therefore particularly encourage applications from UK BME candidates. All scholarships will be awarded on the basis of merit.</em></p>

<h2 class="heading heading--sm">Entry requirements</h2>

Applicants to research degree programmes should normally have at least a first class or an upper second class British Bachelors Honours degree (or equivalent) in an appropriate discipline. The criteria for entry for some research degrees may be higher, for example, several faculties, also require a Masters degree. Applicants are advised to check with the relevant School prior to making an application. Applicants who are uncertain about the requirements for a particular research degree are advised to contact the School or Graduate School prior to making an application.

<h2 class="heading heading--sm">English language requirements</h2>

The minimum English language entry requirement for research postgraduate research study is an IELTS of 6.0 overall with at least 5.5 in each component (reading, writing, listening and speaking) or equivalent. The test must be dated within two years of the start date of the course in order to be valid. Some schools and faculties have a higher requirement.
