ERC FUNDED PROJECTS

The current trend in biophotonics is to try and replicate the same ease and precision that our hands, eyes and ears offer at the macroscopic level, e.g. to hold, observe, squeeze and pull, rotate, cut and probe biological specimens in microfluidic environments. The bidding to get closer and closer to the object of interest has prompted the development of extremely advanced manipulation techniques at scales comparable to that of the wavelength of light. However, the fact that the optical beam can only access the microfluidic chip from the narrow aperture of a microscopic objective limits the versatility of the photonic function that can be realized. With this project, the applicant proposes to introduce a new biophotonic platform based on the all optical manipulation of flexible photonic metasurfaces. These artificial two-dimensional materials have virtually arbitrary photonic responses and have an intrinsic exceptional mechanical stability. This cross-disciplinary project, bridging photonics, material sciences and biology, will enable the adoption of the most modern and advanced photonic designs in microfluidic environments, with transformative benefits for microscopy and biophotonic applications at the interface of molecular and cell biology.

In the epoch of Gaia, fundamental stellar properties will be made widely available for large numbers of stars. These properties are expected to unleash a new wave of discovery in the field of astrophysics. But while many properties of stars are measurable, meaningful Helium abundances (Y) remain elusive and as a result fundamental properties are not accurate. Helium enrichment laws, which underpin most stellar properties, link initial Y to initial metallicity, but these relations are very uncertain with gradients (dY/dZ) spanning the range 1 to 3. This uncertainty is the initial Y problem and this is a bottleneck that must be overcome to unleash the true potential of Gaia. Without measurements of initial Y for all stars we need to find alternative observables that trace out the evolution of initial Y. We will search for better tracers using the power of asteroseismology as a calibrator. Asteroseismic measures of Helium will be used to construct a map from observable properties (fundamental, chemical or even dynamical) back to initial Helium. This is a challenge that can only be solved through the use of the latest asteroseismic techniques coupled to a rigorous yet flexible statistical scheme. I am uniquely qualified in the cutting edge methods of asteroseismology and the application of advanced multi-level statistical models. The intersection of these two skill sets will allow me to solve the initial Helium problem. The motivation for a timely solution to this problem could not be stronger. We have just entered an age of large asteroseismic datasets, vast spectroscopic surveys, and the billion star program of Gaia. The next wave of scientific breakthroughs in stellar physics, exoplanetary science, and Galactic archeology will be held back unless accurate fundamental stellar properties are available. We can only produce these accurate properties with a reliable map of stellar Helium.

Galaxies are the building blocks of structure in the Universe; this proposal seeks to understand how their shapes, colours and dynamics are determined. For example, what happened in the history of some galaxies to transform them into passive ellipticals while others, seemingly of the same mass and in the same environment, are star-forming spirals? Even such a basic question about the link between morphology and star formation has not yet been answered, revealing our theories of galaxy formation are inadequate. This is a major concern in an era where understanding the shapes of galaxies and how they relate to the underlying dark matter is essential for progress in precision cosmology. This project will build the missing link between the history of a galaxy and its observational properties (i.e. between cause and effect) by using numerical simulations. Current research in this area rightly gives significant attention to the crucial problem of how feedback – energy input from supernovae, active galactic nuclei, and more – affect observable properties. But as well as investigating this avenue, GM Galaxies will uniquely make use of my new technique (“genetic modification”) to systematically investigate the role of the galaxy’s merging and accretion history at high resolution. To distinguish the fingerprints of history from the effects of feedback, we will compare to rich new data from integral field unit surveys; these reveal, for example, galactic metallicity and velocity maps. My pilot study for this project shows that such measures of a galaxy disambiguate between alternative formation routes to galaxies which would appear similar by photometric measures alone. Similarly, we will make predictions for the observable properties of the gas reservoir surrounding galaxies and for integral field observations at high redshift. In this way we will make a predictive account of how galactic structure is determined by the interaction of the accretion history with feedback.

Poetry was the most affordable art form in the Roman world: all it required were words, and someone with a talent to arrange them in a meaningful, aesthetically convincing way. Yet, the study of Latin poetry has traditionally almost exclusively focused on a small, judiciously transmitted canon of texts – a segment of Rome’s artistic production that favours the poetry that was produced, enjoyed, and controlled, by a political, social, and financial urban elite, reinforcing their claim to cultural superiority. Focusing on a body of over 4,000 Latin verse inscriptions that have survived from the third century B. C. to Late Antiquity and cover the Roman empire in its entirety, representing ancient Rome’s middle and lower social strata in particular, MAPPOLA is an unprecedented effort to democratise our understanding of Roman poetry. A fundamentally multidisciplinary project that will make use of recent methodological advances in linguistic, historical, and archaeological scholarship, MAPPOLA’s prime aim is fundamentally to reassess the verse inscriptions as evidence for poetry as a ubiquitous, inclusive cultural practice of the people of ancient Rome beyond the palaces of its urban aristocracy. It will provide answers to the following questions: How is the empire’s considerable regional and ethnic diversity reflected in the engagement with inscribed verse? How and where did poetic landscapes emerge, and what inspired them? What was the cultural and social significance of inscribed Latin verse? How did subcultures and poetic subversion take shape? How did inscribed poetry transcend and transgress artificially imposed boundaries and abstractions? Over five years, organised into five integrated Work Packages and firmly rooted in the PI’s long-term vision, MAPPOLA will open a new area of empirical and quantitative research, alongside traditional qualititative approaches, into Latin poetry and its European legacy.
