I plan to conduct cross sectional surveys in five demographic surveillance sites across sub-Saharan Africa, to identify cases of active convulsive epilepsy (ACE). This cohort will be used to determine the prevalence of ACE and the extent of the number of people not receiving treatment (treatmetn gap) in these sites, identify the causes (particularly parasitic diseases that could be prevented) and establish cohorts of people with epilepsy, from which the magnitude and causes of excess mortality a ssociated with epilepsy can be determined. In addition, a community based intervention will be tested through a randomised cluster trial in one of the sites, to reduce the treatment gap and improve the quality of life of people with epilepsy in this area.
Using new evidence synthesis techniques to explore health and care inequalities among Lesbian, Gay, Bisexual and Transgender people 24 May 2017
This proposal will utilise a developing approach to synthesising existing quantitative data in order to substantially enhance the evidence-base around health, wellbeing and care inequalities among Lesbian, Gay, Bisexual and Transgender (LGBT) people. The aims of this project are to: Review the potential of nationally representative UK datasets for individual participant data meta-analysis on the health, wellbeing and care states of LGBT people in the UK Apply individual participant data meta-analysis, to develop robust estimates around LGBT health, wellbeing and care needs and inequalities. The analysis will first focus on four target measures of general health, alcohol consumption, mental wellbeing, and provision and receipt of social care among older LGBT people. Develop policy and research recommendations arising from the modelling. By combining evidence from multiple datasets we expect to show representative findings for LGBT outcomes (including statistically significant differences) that we would otherwise not have sufficient power to detect if modelling within individual datasets alone. Develop a network collaborators to expand the approach trialled above, creating a stronger evidence base of LGBT health and care needs across different age groups, intersectionalities, and also across international settings including low and middle income countries.

The Congress for Curious People. 30 Aug 2013
We are seeking support for a trans-disciplinary series of lectures and performances, The Congress for Curious People, which is addressing popular variants of scientific knowledge and its social, historical and cultural dimensions. From August 30th to September 8th 2013 this event will be held in multiple venues in London, exploring more specifically relationships between the sciences and spectacle in contemporary society. Beginning with a series of evening lectures and performances and culminati ng in a two-day symposium, the Congress will feature the work of historians of art and science, museum professionals, performers and artists as well as problematise this field and specifically ethical issues around spectatorship. The Congress will create not only a forum for discussing but also for experiencing spectacle, entangling the academic with the popular spheres. Its structure is trans-disciplinary, meaning it is mixing performances, discussions and academic papers in order to question t he abyss between academic reflection and spectacular practices.
My current and previous Wellcome Trust Fellowships (Henry Wellcome, 2009-13; Henry Dale 2014- present) focus on important aetiological questions about psychotic disorders, using epidemiological data. Psychotic disorders are a debilitating set of mental health disorders, characterised by hallucinations, delusions and cognitive deficits. My research demonstrates that these disorders have a robust, replicable social aetiology, with higher incidence rates observed in young people,1–3 men,1–3 ethnic minorities2–7 and people exposed to greater social disadvantage.8–11 In my previous fellowship, I established the largest epidemiological study of first episode psychosis [FEP] in England since 1999, to demonstrate that these substantial mental health inequalities also exist in more rural populations (East Anglia)3,12; rates are over twice as high as expected,3,13 with deprived rural communities experiencing the highest psychosis incidence. This study has generated new Page 5 of 18 aetiological clues, for example by showing that people at "ultra-high risk" of psychosis are exposed to similar social and spatial markers of social disadvantage as FEP patients,14 implicating an aetiological role for social adversities prior to onset. I have also demonstrated that migrants face greatest FEP risk when immigrating in childhood,15 an important period of sociocognitive development. I am attempting to replicate this in my current Fellowship, in a larger longitudinal cohort using Swedish national register data. Using this data, I have already shown that refugees are at elevated psychosis risk compared with other migrants from the same region of origin,7 providing further insights into the possible social determinants of psychosis. Epidemiological data can also inform mental health service planning. In England, Early Intervention in Psychosis [EIP] services assess and treat people with suspected FEP, offering evidence-based multidisciplinary care to improve downstream clinical and social outcomes, shown to be highly costeffective.16 Unfortunately, original policy implementation guidance17 made no provision for the heterogeneity in incidence described above, with services commissioned on a uniform expectation of 15 new cases per 100,000 people-per-year. This was at least half the true incidence,1,3 and over three times lower than the overall referral rate for all suspected FEP, including "false positive" (nonFEP) referrals,3 who still require appropriate psychiatric triage and signposting, and consume additional EIP resources not factored into original guidance. In response, I demonstrated that epidemiological estimates of psychosis risk could be used to better predict the expected FEP incidence in the population at-risk in England,13 nationally and regionally. The tool, known as PsyMaptic, has had substantial impact on policy and commissioning since it was freely-released in 2012 (www.psymaptic.org).16,18–22 Most recently, it has been used to inform national EIP workforce calculations23 following the introduction of Access and Waiting time standards,19 as part of the Department of Health’s commitment to achieving parity of esteem between mental and physical health by 2020.24 Whilst I have demonstrated, via PsyMaptic, that it is possible to translate epidemiological data into effective public mental health,25 some vital methodological limitations require empirical attention. I therefore seek Wellcome Trust enhancement funding to answer four empirical questions to develop and apply novel statistical prediction methodologies to generate sustainable, dynamic populationbased models of future mental health need.
What's in a voice? 30 May 2017
Why do we sound the way we do? "What’s in a voice", is an exhibit which aims to start conversations about voices, and which illustrates the evolution, complexity and meanings associated with the human voice – which is simultaneously a musical instrument without peer in terms of flexibility and range, and also a powerful social instrument with which we express who we are, how we are, and who we would like to be. This project will tell the story of the human voice – from evolution to acoustics, from anatomy to emotion – in novel and engaging ways. We will illustrate this with a strong scientific background into our work on voices, and also with demonstrations of why and how our voices can change, as well as the use of different kinds of vocal performance to allow us to illustrate the different kinds of vocal mechanisms live. The performances will involve voice professionals, including beat boxers, actors, poets, rappers and singers. We are also working with people who have more ‘difficult’ voices, (e.g. people who stammer), and children from a local Camden primary school (St George the Martyr, Camden), with whom we are working to produce some vocal demonstrations.
Identification and Validation of the Determinants of Variation in T cell Immunity in Health and in Inherited Immunodeficiency Syndromes 30 Sep 2018
Vaccination is a powerful strategy to prevent infectious diseases, by stimulating our immune system to produce antibodies. However, vaccines have not been as successful in boosting immunity against infections that require a different defence called T-cells. This problem is exemplified by tuberculosis, which causes more deaths than any other infection despite the use of the Bacillus Calmette-Guérin (BCG) vaccine, because the protection provided by BCG is variable. I aim to understand why BCG only works in some people. I will investigate the idea that differences in T-cell activation in different people are responsible for differences in the protective effects of BCG. In healthy individuals, I will test T-cell activation in response to a general stimulus. Using these data, I will develop a mathematical model to understand how variation in T-cell responses comes about. I will then In BCG-vaccinate the same individuals and test if my model explains all the variability in responses to BCG and in T-cell control of tuberculosis. These experiments may reveal the molecular switches that are responsible for differences in BCG efficacy. By testing cells from patients with genetic abnormalities in some of these molecules, I will validate their role in providing effective T-cell immunity.
Young people in sub-Saharan Africa are central to ending the HIV epidemic. However, uptake of proven protective interventions is low and evidence on who does/does not engage is limited. Theory predicts that behaviours and intervention uptake cluster within social networks. Interventions in other settings have successfully leveraged social ties to improve intervention impact. I aim to: (1) use novel methods to identify how social networks pattern risk for HIV acquisition; and (2) test the feasibility of using such knowledge to improve intervention uptake. I will undertake this work at the Africa Health Research Institute in rural KwaZulu-Natal, South Africa. Following qualitative interviews with young people exploring their social networks and social norms, we will then quantitatively follow 600 15-24 year-olds, together with their close friends and family, for three years. Using these longitudinal data, we will statistically model how social contacts influence behaviour and HSV/HIV acquisition. We will then quantitatively and qualitatively evaluate the feasibility of using network-selected peer-educators to promote uptake of HIV self-tests and subsequent treatment. We will compare how influential peer-educators differ from randomly selected ones in terms of willingness to be involved, training dynamics and health impact.
Planning Quechua Families: Indigenous Subjectivities, Inequalities & Kinship under the Peruvian Family Planning Programme 10 May 2016
This research will investigate how the Peruvian family planning (FP) programme is currently being implemented in an indigenous community, and the wider affects that this public health intervention may have on their family and community networks, as well as on a personal level. Anthropological literature describes how [bio] medical interventions can affect subjectivities and how people view their bodies, which can alter personal & community relationships sometimes to the detriment of the individual. In this study the results of enforced [bio] medical FP will be investigated to ascertain what affects, if any, the FP programme has on traditional kinship and community networks which the Quechua-indigenous rely upon in the Andes. This is also a political issue, as in the recent past (1990-2000) the Peruvian government used coercion to sterilize 200,000+ rural-indigenous people without consent, which was seen as a way of controlling the fertility of this ‘less-desirable’ sub-population. Today this group are once again being targeted for intervention. The project will investigate if there are any contemporary issues with lack of information, misinformation or discriminatory practise as before, by exploring how the programme is being delivered to indigenous communities.

The Neuroscience of Nudge 01 Apr 2016
Nudges are simple behavioural methods designed to influence decision making by taking advantage of people’s implicit biases. One important type of nudge is known as "anchoring." The simple presentation of an irrelevant number affects people’s decisions by shifting estimations towards that number. This behavioural effect is well understood although the mechanism behind the unconscious bias remains unclear. The brain bases of this effect has received surprisingly little attention in the literature. One study found that the medial prefrontal cortex played a crucial role in anchoring theory-of-mind decisions in a social context, suggesting that activity within cortical networks intrinsic to the task is shaped by this extrinsic information. I propose to initiate this investigation by piloting an fMRI experiment to investigate the neural correlates of anchoring in reasoning about uncertainty. The aim is to collect a preliminary data set from a small sample of healthy adults (n=12) to explore whether the experimental paradigm: yields robust behavioural anchoring effects, identifies brain regions whose activity is affected by these anchoring effects, and tests whether these effects are parametric modulated. I predict that within prefrontal regions engaged by the task, I will observe parametric modulation based on the amplitude of the behavioural anchoring effect.
Shared equipment application for a NIRx Near Infrared Spectrometer (NIRS) system for functional measurements (fNIRS). 11 Jun 2015
We request a Near Infrared Spectrometer (NIRS) to be shared primarily by researchers in speech, hearing and language to make functional NIRS measurements (fNIRS). NIRS is a non-invasive method that measures the absorption of near-infrared light through the intact skull. Similar to fMRI, fNIRS provides an indirect measure of neural activity based on changes in blood oxygenation due to metabolic processes within the cortex. The equipment will be used in research that involves hypotheses that can b e tested based on activations near the cortical surface where the procedures or participants make it difficult or impossible to use fMRI. It can be used with children, people with cochlear implants, and people with conditions or in experiments that make it difficult to remain stationary whilst speaking or listening. The equipment will help extend established research programmes and there are plans in place to permit junior PIs to share and develop new research in a way that will make the facilit y self-sustaining. The research falls within Wellcome Trusts vision statement to improve health.
Created Out of Mind will shape public and professional perceptions of dementia through a dynamic fusion of scientific and creative experimentation. Our Hub residency will support the active connection and collaboration of previously disparate cultures (scientists, artists, commissioners/policymakers) and infuse the insights and skills of people living with dementia, communications professionals and collaboration experts. Common (mis-)conceptions of dementia will be challenged through integrated artistic and scientific investigation of less recognised symptoms associated with typical and rare dementias. The project will investigate the neuroscientific, artistic and social bases of artistic engagement, enjoyment and change across multiple art forms. Interdisciplinary discussion, disagreement and creativity will also challenge and develop thinking regarding the principles, priorities, practice, health benefits and methodologically-robust evaluation of arts in dementia. Our inspiration comes directly from the intriguing experiences, heart-rending questions and puzzling uncertainties of people living with dementia. Team members will become creative collaborators whilst maintaining their professional ‘essence’, yielding a richly and meaningfully interconnected network of multi-skilled science/arts researchers, practitioners and communicators. We will also enrich understanding about dementia by raising provocative questions about the healthy brain, our emotional reactions to change in ourselves and others, and the attributes by which we value and define humanity.
Although schizophrenia affects more than 500,000 people in the UK, its neural basis remains poorly understood. What is increasingly clear is that the diverse range of symptoms associated with the disorder are linked by a pervasive problem with the appropriate processing of context. We have reported that people with schizophrenia are largely immune to a visual illusion that relies on suppressive contextual interactions (contrast gain control). The first series of experiments examine contrast gain control in schizophrenia in some depth. We will modify an established combined fMRI-psychophysics paradigm to (a) measure Threshold-versus-Contrast (TvC) functions and so determine if reduced inhibition confers better detection performance in the test group and (b) relate this to the BOLD contrast response function in test and control groups. The second series of psychophysical experiments will determine if gain control deficits extend into domains other than contrast, such orientation and moti on-direction. Finally we will use fMRI and psychophysics to investigate gain-control in another sensory modality: tactile perception. These findings will contribute both to understanding sensory abnormalities associated with schizophrenia and, we hope, in the potential to diagnose it, using psychophysical and fMRI measures.
