Project title: More than sleeps the eye – The role of REM-sleep and eye movements on the trajectory of distressing memories

Primary supervisor: Dr Hong-Viet V. Ngo-Dehning (University of Essex)

Second supervisor: Dr Tom Foulsham (University of Essex)

University: University of Essex

SENSS Theme: Health, Wellbeing and Social Care

Collaborative partner: SOMNOmedics

Collaborative partner supervisor: Dr Christian Ziegler

Degree structure: The structure of the studentship offered will depend on your personal training needs. However, the minimum duration of a SENSS-funded studentship will be 3.5 years: this covers a PhD and a mandatory placement of approximately 3 months. The maximum duration of a studentship will be 4.5 years: this covers a Masters degree followed by a PhD, as well as the mandatory 3-month placement.

Project background

Approximately 1 in 2 people will experience a distressing event at some point in their life. In most cases, these memories naturally fade over time. However, for about 10% of the population, traumatic experiences develop into post-traumatic stress disorder (PTSD) causing symptoms such as intrusive thoughts, panic attacks and sleep problems, greatly reducing their quality of life. These severe consequences raise the questions of what determines the fade of distressing experience and how can we prevent or treat their maladaptive manifestation.

Intriguingly, our eyes have been identified as a central factor within this mystery. On the one hand, paradoxical sleep or also known as rapid eye movement sleep (REM) named after is hallmarking eye characteristics has been linked to a depotentiation of emotional reactivity of distressing memory. On the other hand, performing slow horizontal eye movements while recalling a distressing experience – a therapeutic approach known as eye movement desensitisation reprocessing (EMDR) – has proven to be a highly effective for the treatment of PTSD and anxiety. Considering this obvious link of eye movements between REM sleep and EMDR, remarkably little to no research has been conducted to shed light into this relation to this day.

The University of Essex is excited to offer a fully funded PhD studentship as part of an ongoing collaborative initiative to tackle this question with a novel line of research which perfectly combines expertise from cognition, neuroscience and medical technology. It will uncover how distressing experiences are shaped by EMDR and REM sleep and will have huge impact on the prevention and treatment of trauma- or anxiety-related disorders and help inspire new, accessible and effective interventions.

The research is an interdisciplinary project led by an academic supervisory team in the Department of Psychology and the industrial partner SOMNOmedics – a German manufacturer of medical technology. It will combine psychological research methods with state-of-the-art sleep technology to conduct empirical research in healthy young participants.

We are looking for a dynamic and committed PhD student to undertake this research to advance our fundamental understanding and innovate new technology with our collaborative partner. The project will give the student a wealth of research experience both in an academic and an industry setting and will be particularly suited to students who wish to develop their career working within or in collaboration with applied research.

Project aims and objectives

This research aims to reveal fundamental insights about the trajectory of distressing memories in three ways:

  1. To uncover the causal link between EMDR and REM-sleep and their role in the consolidation of emotional memories and regulation of emotional valence and arousal

  2. To develop novel interventions to enhance the efficacy of EMDR and REM-sleep to protect against a maladaptive processing of distressing experiences

  3. To discover a link between REM-sleep and the resilience or vulnerability against distressing memories.

Key objectives for this studentship include:

  1. To conduct a comprehensive review of existing literature on sleep, EMDR and their role in the regulation of emotional valence and arousal of distressing/traumatic memories.

  2. To lead the research (including its design, implementation, data collection and data analysis) and collect behavioural and (longitudinal) physiological data during sleep in healthy young participants.

  3. To contribute to the dissemination of findings through academic publications and presentations.

Training opportunities

A comprehensive package of training will be agreed in consultation with the supervisors. Elements of training will be provided by the supervisors, Dr Hong-Viet V. Ngo-Dehning (University of Essex), Dr Tom Foulsham (University of Essex), Dr Christian Ziegler (SOMNOmedics) and by other providers.

The academic supervisors will provide relevant research methods training as required by the student, e.g. in designing and implementing empirical experiments, collecting behavioural and physiological data as well as data analysis, data visualisation and their dissemination.

A three-month placement would take place at SOMNOmedics and would offer the student insights into the day-to-day operations of a manufacturer of medical technology and specifically their research & development department. The placement would begin with a rotation through different business areas to gain a broad overview of the company’s organisational structure (e.g., Service & Support and Quality Management). This would be followed by a collaboration with the Clinical Research team and may include activities such as internal project meetings and the design of a clinical study and its dedicated data analysis.

Studentship details

Studentships are advertised as being between +3.5 and +4.5-year (1+3.5, 2+2.5, +4.5) awards. The standard length of an ESRC-funded studentship is +3.5. This includes the standard +3 PhD, plus an +0.25 (one term) for the integrated placement which you must take as part of your studentship, and a further additional +0.25 (one term) to enable you to undertake training relevant to your research project (including career progression). All studentships are offered on either a full-time or part-time basis. 

The studentship award covers your university fees and provides you with a stipend of £20,780 per year. You will also be able to apply for additional funding via the SENSS Research Training Support Grant to support your training needs.

Residential eligibility

All applicants, whether Home or International, are eligible for a full award, that is, you will receive a stipend (salary) and you will not have to pay any university tuition fees during your studentship award.

How to apply for this studentship

To be considered for this funding, you must first apply to SENSS for this collaborative studentship. Please read the SENSS Collaborative Studentship Application Guidance Notes before completing the online application form. The Guidance Notes are available here.

If your application is accepted by SENSS, you will need to make a separate application for a place to study at the University of Essex as your host University.
