    Disability Matters will transform health research and research environments through a paradigm shift to disability as the driving subject of inquiry. We will develop anti-ableist and anti-disablist approaches that promote inclusive research cultures, broaden health research priorities, innovate research methodologies, generate positive disability representations and cultivate a new generation of equitable health researchers across five countries. Health research still tends to adopt disability as a passive object of intellectual curiosity, empirically investigate disability as a chronic illness or understand disability in terms of impairment or pathology. Disability exists as an ‘absent presence’ - a present problem to be solved by research but absent as a research colleague or scholarly authority - and disabled health researchers are conspicuously absent. Health research often ignores the specificities of disabled people’s lives and the health inequalities that they endure as a consequence of disabling systemic factors. Poor, working class, female, LBGTQ+ and black disabled people are particularly at risk of being forgotten. Our programme of work will address these omissions and generate transformative equity, diversity and inclusion knowledge; thus supporting Wellcome’s strategy to lead the Science and Health sector in challenging ableism and disablism in the practices and cultures of health research.

    The Terahertz (THz) frequency domain has a myriad of anticipated applications such as wireless THz communications, security screening, and bio-chemical sensing. More specifically, bio-chemical sensors operating in the THz spectral region (1-20 THz) are becoming increasingly valuable, as the vibrational transitions of molecules are two to three orders of magnitude stronger in the THz spectral domain than in the visible counterpart, leaving distinctive spectral fingerprints that are very convenient for sensing. The paramount issue to be solved in order to enable these applications is the lack of a THz detector that is altogether fast, sensitive, compact and operating at room temperature. The proposal TIGER aims at creating a new generation of THz optomechanical CMOS-compatible detectors with integrated germanium nanolasers. The substantial originality of our proposal lies in the convergence of the two significant research fields, THz optomechanical metamaterial system and mechanically-engineered silicon photonics, that has never envisioned before for the technologically important THz frequency range. Our device benefits from 3 different physical domains: (1) metamaterial, (2) optomechanics, and (3) laser physics. In our structure, a metamaterial resonator receives THz radiation and confines a strong electromagnetic field into an ultra-sub-wavelength scale, which leads to a mechanical vibration within a pre-stressed germanium photonic crystal nanobeam laser. The mechanical action induces strong changes in the output characteristics of germanium laser (e.g. peak wavelength position, amplitudes), which, in turn, provide detailed information on the incoming THz radiation. The output of germanium laser can also be fed into integrated photodetectors that give rise to electrical signals. As the mechanical element is typically of nanometer dimensions, its frequency response is in the MHz range, thus much faster than any existing THz detectors operating at room temperature. Furthermore, the germanium devices are fully compatible with silicon-based technology; our THz detectors can be naturally integrated in CMOS platforms, leading to compact THz sensing devices.
