Turok Review edited by Katherine Heyworth, [email protected] Design © UCL Creative Media Services 1 WELCOME Welcome Welcome to another annual review of the activities of the UCL Department of Physics & Astronomy. Inside you will find items focusing on research highlights, as well as features on selected staff, students and events over the past year. I hope these speak for themselves, giving a true impression of the lively and exciting intellectual life of one of the UK’s leading Physics & Astronomy Departments. There are also statistics, including grant income and student admissions. While ploughing through these in detail may be a challenge, they also convey an important message; that the Department Professor Jon Butterworth, Head of Department and Dr Tony Harker, Deputy Head of Department continues to thrive, our activities are well recognised and people want to join us.

It is with this interactivity in mind that we are hosting lively structured debates on current issues. Through the use of e-voting, we encourage audience participation in the hope of provoking thought and stimulating discussion. We are very fortunate to have with us over the two days such a high quality, international faculty and are very much looking forward to their contributions. Throughout the event e-Posters will be displayed in the exhibition area. Please visit this area and view them at your leisure. As well, please see the e-Poster programme for details of when authors will be presenting their work for 2 minutes at allocated times at e-Poster stations on Level -1. We would also encourage you to visit all of the exhibitors on the mezzanine level, as without their continued support we would not be able to run this conference.

  • We Have an Exciting Opportunity for an ENT Trainee Or ENT Surgeon to Play a Key Role in a Ground Breaking First in Human Trial O
    UCL EAR INSTITUTE SENIOR or PRINCIPAL CLINICAL RESEARCH FELLOW (CL8 or 9) 0.8 FTE We have an exciting opportunity for an ENT trainee or ENT surgeon to play a key role in a ground breaking first in human trial of a novel therapy to treat hearing loss. The REGAIN project (REgeneration of inner hair cells with GAmma secretase INhibitors) is funded by the prestigious EU Horizon 2020 programme and aims to deliver a phase I/II study to test the safety and efficacy of a gamma secretase inhibitor in adults with mild to moderate sensorineural hearing loss. This innovative project is led by Prof Anne Schilder and Prof Shakeel Saeed, and will be conducted at the Royal National Throat Nose and Ear Hospital, in collaboration with the UCL Ear Institute and partner sites across Europe. We are looking for an enthusiastic and motivated senior ENT trainee, or a recently qualified ENT surgeon, to provide essential clinical support to the trial. She/he will be a key figure in the delivery of the trial, supported by research nurses and audiologists as part of the REGAIN team. In parallel to trial delivery, the post holder will be encouraged and supported to develop their own hearing research related to the trial, tailored to background and expertise. The postholder will therefore have a keen interest in translational research and developing a clinical academic career in the field of ENT, hearing and balance. She/he will be flexible, pro-active and able to work under own initiative. The appointment is either to the Senior Clinical Research Fellow or the Principal Clinical Research Fellow grade.

  • Clinical Lecturer in Paediatrics Job Description
    UCL SCHOOL OF LIFE AND MEDICAL SCIENCES UCL FACUTY OF POULATION HEALTH SCIENCES INSTITUTE OF CHILD HEALTH CLINICAL LECTURER IN PAEDIATRICS JOB DESCRIPTION INTRODUCTION The UCL Institute of Child Health (ICH) The mission of the UCL Institute of Child Health is to improve the health and well-being of children, and the adults they will become, through world-class research, education and public engagement. This strategy has been informed by the insights gained from visits to six other internationally excellent children’s academic medical centres and by detailed discussions internally and with our external partners, including GODH, GOSH Children’s Charity, the wider UCL community, UCL Partners and funding bodies. The UCL Institute of Child Health, together with its clinical partner Great Ormond Street Hospital for Children, forms the largest concentration of children’s health research outside North America. In 2013 ICH developed a new academic strategy which focuses on five scientific programmes: • Genetics and Genomic Medicine • Population, Policy and Practice • Developmental Biology and Cancer • Developmental Neurosciences • Infection, Immunity and Inflammation Four key principles underpin these programmes and the academic strategy: Interdisciplinarity. ICH will facilitate the best scientists, from all relevant academic and clinical disciplines, to work together to address fundamental questions to improve the health of children. Accelerating translation. ICH will support the rapid translation of findings from basic discoveries relevant to understanding of health and disease, to clinical studies, more directly aimed at improving the clinical care of children. We will also support “reverse translation” from observations in clinical and population studies to basic studies which address mechanisms of health and disease.

  • Effects of Remote Microphone Hearing Aids (Rmhas) on Listening-In-Noise, Attention and Memory in School-Aged Children with Auditory Processing Disorder (APD)
    Effects of Remote Microphone Hearing Aids (RMHAs) on Listening-in-Noise, Attention and Memory in School-Aged Children with Auditory Processing Disorder (APD) ----- Georgios Stavrinos ----- A thesis submitted for the degree of Doctor of Philosophy ----- University College London Faculty of Brain Sciences Ear Institute ----- University College London September 2018 1 DECLARATION I, Georgios Stavrinos, confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated in the thesis. 2 ACKNOWLEDGMENTS This has been one of the most challenging long-term projects I ever took on and it would not have been completed without the contribution, help, guidance, discussions and support from all the wonderful people mentioned here. I would first like to give warm thanks to the children, their parents and teachers who took part in my study. They were all very willing to contribute to the study and their patience and dedication is much appreciated. Of course, this project would not have been realised without the contribution from the funders of the project, GN ReSound and Action Medical Research. I am therefore grateful for their support. His support was constant for thirty-something years and without him I would not have been in the position to even start this PhD project. A lot of gratitude and love goes out to my father, Panagiotis Stavrinos, whom I had the misfortune to lose before he saw me complete this journey of which he was so supportive. The supervision and guidance of my supervisor, Professor Doris Bamiou, throughout this project have been nothing short of excellent.

  • From Small Library Beginnings a Brief History of UCL Library Services
    UCL LIBRARY SERVICES From Small Library Beginnings A brief history of UCL Library Services An exhibition of material from UCL Special Collections 4 March – 13 December 2019 From Small Library Beginnings A brief history of UCL Library Services An exhibition of material from UCL Special Collections 4 March – 13 December 2019 #ucllibrariesexhib Preface UCL Library Services today comprises a modern, multi-site department with print collections numbering two million books, rich and diverse archives, extensive online resources and over 4,000 study spaces. The earliest collection, built up by the first Librarian, the Reverend Dr Francis Augustus Cox, numbered just 6,500 volumes in 1829. These were accommodated in what was known as the ‘Small Library’ at the southern end of the Wilkins Building. For some 40 years after 1831, with no formally appointed Librarian and limited funds, the collections grew mainly through donations and bequests. In the twentieth century the Library survived air raids and continued to grow, while in 1919 UCL’s School of Librarianship opened – precursor to the Department of Information Studies now proudly celebrating its centenary. This exhibition narrates the unique and absorbing history of UCL’s libraries. It highlights some of the spaces, collections and people that have been integral to their development, drawing on a selection of items from UCL Special Collections.
