Sensors permeate our society, measurement underpins quantitative action and standardized accurate measurements are a foundation of all commerce. The ability to measure parameters and sense phenomena with increasing precision has always led to dramatic advances in science and in technology - for example X-ray imaging, magnetic resonance imaging (MRI), interferometry and the scanning-tunneling microscope. Our rapidly growing understanding of how to engineer and control quantum systems vastly expands the limits of measurement and of sensing, opening up opportunities in radically alternative methods to the current state of the art in sensing. Through the developments proposed in this Fellowship, I aim to deliver sensors enhanced by the harnessing of unique quantum mechanical phenomena and principles inspired by insights into quantum physics to develop a series of prototypes with end-users. I plan to provide alternative approaches to the state of the art, to potentially reduce overall cost and dramatically increase capability, to reach new limits of precision measurement and to develop this technology for commercialization. Light is an excellent probe for sensing and measurement. Unique wavelength dependent absorption, and reemission of photons by atoms enable the properties of matter to be measured and the identification of constituent components. Interferometers provide ultra-sensitive measurement of optical path length changes on the nanometer-scale, translating to physical changes in distance, material expansion or sample density for example. However, for any canonical optical sensor, quantum mechanics predicts a fundamental limit of how much noise in such experiment can be suppressed - this is the so-called shot noise and is routinely observed as a noise floor when using a laser, the canonical "clean" source of radiation. By harnessing the quantum properties of light, it is possible reach precision beyond shot noise, enabling a new paradigm of precision sensors to be realized. Such quantum-enhanced sensors can use less light in the optical probe to gain the same level of precision in a conventional optical sensor. This enables, for example: the reduction of detrimental absorption in biological samples that can alter sample properties or damage it; the resolution of weak signals in trace gas detection; reduction of photon pressure in interferometry that can alter the measurement outcome; increase in precision when a limit of optical laser input is reached. Quantum-enhanced techniques are being used by the Laser Interferometer Gravitational Wave Observatory (LIGO) scientific collaboration to reach sub-shot noise precision interferometry of gravitational wave detection in kilometer-scale Michelson interferometers (GEO600). However, there is otherwise a distinct lack of practical devices that prove the potential of quantum-enhanced sensing as a disruptive technology for healthcare, precision manufacture, national security and commerce. For quantum-enhanced sensors to become small-scale, portable and therefore practical for an increased range of applications outside of the specialized quantum optics laboratory, it is clear that there is an urgent need to engineer an integrated optics platform, tailored to the needs of quantum-enhanced sensing. Requirements include robustness, miniaturization inherent phase stability and greater efficiency. Lithographic fabrication of much of the platform offers repeatable and affordable manufacture. My Fellowship proposal aims to bring together revolutionary quantum-enhanced sensing capabilities and photonic chip scale architectures. This will enable capabilities beyond the limits of classical physics for: absorbance spectroscopy, lab-on-chip interferometry and process tomography (revealing an unknown quantum process with fewer measurements and fewer probe photons).

Synthetic Biology is the underpinning discipline for advances in the UK bioeconomy, a sector currently worth ~£200Bn GVA globally. It is a technology base that is revolutionising methods of working in the biotechnology sector and has been the subject of important Government Roadmaps and supported by significant UKRI investments through the Synthetic Biology for Growth programme. This is now leading to a vibrant translational landscape with many start-ups taking advantage of the rapidly evolving technology landscape and traditional industries seeking to embed new working practices. We have sought evidence from key industry leaders within the emerging technology space and received a clear and consistent response that there is a significant deficit of suitably trained PhDs that can bridge the gap between biological understanding and data science. Our vision is a CDT with an integrative training programme that covers experimentation, coding, data science and entrepreneurship applied to the design, realisation and optimisation of novel biological systems for diverse applications: BioDesign Engineers. It directly addresses the priority area 'Engineering for the Bioeconomy' and has the potential to underpin growth across many sectors of the bioeconomy including pharmaceutical, healthcare, chemical, energy, and food. This CDT will bring together three world-leading academic institutions, Imperial College London (Imperial), University of Manchester (UoM) and University College London (UCL) with a wide portfolio of industrial partners to create an integrated approach to training the next generation of visionary BioDesign Engineers. Our CDT will focus on providing an optimal training environment together with a rigorous interdisciplinary program of cohort-based training and research, so that students are equipped to address complex questions at the cutting edge of the field. It will provide the highly-skilled workforce required by this emerging industry and establish a network of future UK Bioindustry leaders. The joint location of the CDT in London and Manchester will provide a strong dynamic link between the SE England biotech cluster and the Northern Powerhouse. Our vision, which brings together a BioDesign perspective with Engineering expertise, can only be delivered by an outstanding and proven grouping of internationally renowned researchers. We have a supervisor pool of 66 world class researchers that span the associated disciplines and have a demonstrated commitment to interdisciplinary research and training. Furthermore, students will work directly with the London and Manchester DNA Foundries, embedding the next generation bioscience technologies and automation in their training and working practices. Cohort training will be delivered through a common first year MRes at Imperial College London, with students following a 3-month taught programme and a 9-month research project at one of the 3 participating institutions. Cohort and industry stakeholder engagement will be ensured through bespoke training and CDT activities that will take place every 6 months during the entire 4-year span of the programme and include multi-year group hackathons, training in responsible research and innovation, PhD research symposia, industry research days, and entrepreneurial skills training. Through this ambitious cohort-based training, we will deliver PhD-level BioDesign Engineers that can bridge the gap between rigorous engineering, efficient model-based design, in-depth cellular and biomolecular knowledge, high throughput automation and data science for the realisation and exploitation of engineered biological systems. This unique cohort-based training platform will create the next generation of visionaries and leaders needed to accelerate growth of the UK bioeconomy.

Recently, an influential American business magazine, Forbes, chose Quantum Engineering as one of its top 10 majors (degree programmes) for 2022. According to Forbes magazine (September 2012): "a need is going to arise for specialists capable of taking advantage of quantum mechanical effects in electronics and other products." We propose to renew the CDT in Controlled Quantum Dynamics (CQD) to continue its success in training students to develop quantum technologies in a collaborative manner between experiment and theory and across disciplines. With the ever growing demand for compactness, controllability and accuracy, the size of opto-electronic devices in particular, and electronic devices in general, is approaching the realm where only fully quantum mechanical theory can explain the fluctuations in (and limitations of) these devices. Pushing the frontiers of the 'very small' and 'very fast' looks set to bring about a revolution in our understanding of many fundamental processes in e.g. physics, chemistry and even biology with widespread applications. Although the fundamental basis of quantum theory remains intact, more recent theoretical and experimental developments have led researchers to use the laws of quantum mechanics in new and exciting ways - allowing the manipulation of matter on the atomic scale for hitherto undreamt of applications. This field not only holds the promise of addressing the issue of quantum fluctuations but of turning the quantum behaviour of nano- structures to our advantage. Indeed, the continued development of high-technology is crucial and we are convinced that our proposed CDT can play an important role. When a new field emerges a key challenge in meeting the current and future demands of industry is appropriate training, which is what we propose to achieve in this CDT. The UK plays a leading role in the theory and experimental development of CQD and Imperial College is a centre of excellence within this context. The team involved in the proposed CDT covers a wide range of key activities from theory to experiment. Collectively we have an outstanding track record in research, training of postgraduate students and teaching. The aim of the proposed CDT is to provide a coherent training environment bringing together PhD students from a wide variety of backgrounds and giving them an appreciation of experiment and theory of related fields under the umbrella of CQD. Students graduating from our programme will subsequently find themselves in high-demand both by industry and academia. The proposed CDT addresses the EPSRC strategic area 'Quantum Information Processing and Quantum Optics" and one of the priority areas of the CDT call, "Towards Quantum Technologies". The excellence of our doctoral training has been recognised by the award of a highly competitive EU Innovative Doctoral Programme (IDP) in Frontiers of Quantum Technology, which will start in October 2013 running for four years with the budget around 3.8 million euros. The new CDT will closely work with the IDP to maximise synergy. It is clear that other high-profile activities within the general area of CQD are being undertaken in a range of other UK universities and within Imperial College. A key aim of our DTC is inclusivity. We operate a model whereby academics from outside of Imperial College can act as co-supervisors for PhD students on collaborative projects whereby the student spends part of the PhD at the partner institution whilst remaining closely tied to Imperial College and the student cohort. Many of the CDT activities including lectures and summer schools will be open to other PhD students within the UK. Outreach and transferable skills courses will be emphasised to provide a set of outreach classes and to organise various outreach activities including the CDT in CQD Quantum Show to the general public and CDT Festivals and to participate in Imperial's Science Festivals.

The CDT proposal 'Fuel Cells and their Fuels - Clean Power for the 21st Century' is a focused and structured programme to train >52 students within 9 years in basic principles of the subject and guide them in conducting their PhD theses. This initiative answers the need for developing the human resources well before the demand for trained and experienced engineering and scientific staff begins to strongly increase towards the end of this decade. Market introduction of fuel cell products is expected from 2015 and the requirement for effort in developing robust and cost effective products will grow in parallel with market entry. The consortium consists of the Universities of Birmingham (lead), Nottingham, Loughborough, Imperial College and University College of London. Ulster University is added as a partner in developing teaching modules. The six Centre directors and the 60+ supervisor group have an excellent background of scientific and teaching expertise and are well established in national and international projects and Fuel Cell, Hydrogen and other fuel processing research and development. The Centre programme consists of seven compulsory taught modules worth 70 credit points, covering the four basic introduction modules to Fuel Cell and Hydrogen technologies and one on Safety issues, plus two business-oriented modules which were designed according to suggestions from industry partners. Further - optional - modules worth 50 credits cover the more specialised aspects of Fuel Cell and fuel processing technologies, but also include socio-economic topics and further modules on business skills that are invaluable in preparing students for their careers in industry. The programme covers the following topics out of which the individual students will select their area of specialisation: - electrochemistry, modelling, catalysis; - materials and components for low temperature fuel cells (PEFC, 80 and 120 -130 degC), and for high temperature fuel cells (SOFC) operating at 500 to 800 degC; - design, components, optimisation and control for low and high temperature fuel cell systems; including direct use of hydrocarbons in fuel cells, fuel processing and handling of fuel impurities; integration of hydrogen systems including hybrid fuel-cell-battery and gas turbine systems; optimisation, control design and modelling; integration of renewable energies into energy systems using hydrogen as a stabilising vector; - hydrogen production from fossil fuels and carbon-neutral feedstock, biological processes, and by photochemistry; hydrogen storage, and purification; development of low and high temperature electrolysers; - analysis of degradation phenomena at various scales (nano-scale in functional layers up to systems level), including the development of accelerated testing procedures; - socio-economic and cross-cutting issues: public health, public acceptance, economics, market introduction; system studies on the benefits of FCH technologies to national and international energy supply. The training programme can build on the vast investments made by the participating universities in the past and facilitated by EPSRC, EU, industry and private funds. The laboratory infrastructure is up to date and fully enables the work of the student cohort. Industry funding is used to complement the EPSRC funding and add studentships on top of the envisaged 52 placements. The Centre will emphasise the importance of networking and exchange of information across the scientific and engineering field and thus interacts strongly with the EPSRC-SUPERGEN Hub in Fuel Cells and Hydrogen, thus integrating the other UK universities active in this research area, and also encourage exchanges with other European and international training initiatives. The modules will be accessible to professionals from the interacting industry in order to foster exchange of students with their peers in industry.

Radioactive isotopes have ratio of protons and neutrons that results in their instability. This presents both a plethora of opportunities, and a challenge to obtain them due to their finite nature. This work seeks to meet the rising medical demand for these exotic isotopes, through the development of new technologies and approaches for radioactive isotope production and separation. While the use of established medical isotopes is growing, there are challenges to the supply as nuclear research reactors are decommissioned across the world. Additionally, the application of non-standard isotopes such as 225Ac have shown significant promise for the treatment of cancers, while others have applications in medical imaging. Reliable processes for the production and separation of these isotopes are required to realise the full potential of these applications and to produce pre-clinical amounts for initial studies. This work seeks to address this through ion source and electromagnetic mass separator development for exotic medical isotope production.
