Summary The emergence of coherent behaviour is ubiquitous in the natural world and has long captivated biologists and physicists alike. One area of growing interest is the collective motion and synchronization arising within and between simple motile organisms. My goal is to develop and use a novel experimental approach to unravel the origins of spontaneous coherent motion in three model systems of biofluids: (1) the synchronization of the two flagella of green algae Chlamydomonas Rheinhardtii, (2) the metachronal wave in the cilia of protist Paramecium and (3) the collective motion of swimming microorganisms in active suspensions. Understanding the mechanisms leading to collective motion is of tremendous importance because it is crucial to many biological processes such as mechanical signal transduction, embryonic development and biofilm formation.
Up till now, most of the work has been theoretical and has led to the dominant view that hydrodynamic interactions are the main driving force for synchronization and collective motion. Recent experiments have challenged this view and highlighted the importance of direct mechanical contact. New experimental studies are now crucially needed. The state-of-the-art of experimental approaches consists of observations of unperturbed cells. The key innovation in our approach is to dynamically interact with microorganisms in real-time, at the relevant time and length scales. I will investigate the origins of coherent motion by reproducing synthetically the mechanical signatures of physiological flows and direct mechanical interactions and track precisely the response of the organism to the perturbations. Our new approach will incorporate optical tweezers to interact with motile cells, and a unique μ-Tomographic PIV setup to track their 3D micron-scale motion.
This proposal tackles a timely question in biophysics and will yield new insight into the fundamental principles underlying collective motion in active biological matter.

Call Details Starting Grant (StG), SH6, ERC-2018-STG
Summary AncientAdhesives addresses the most crucial problem in Palaeolithic archaeology: How to reliably infer cognitively complex behaviour in the deep past. To study the evolution of Neandertal and modern human cognitive capacities, certain find categories are taken to reflect behavioural and thus cognitive complexitye.g. Among these are art objects, personal ornaments and complex technology. Of these technology is best-suited to trace changing behavioural complexity, because 1) it is the least vulnerable to differential preservation, and 2) technological behaviours are present throughout the history of our genus. Adhesives are the oldest examples of highly complex technology. They are also known earlier from Neandertal than from modern human contexts. Understanding their technological complexity is thus essential to resolve debates on differences in cognitive complexity of both species. However, currently, there is no agreed-upon method to measure technological complexity.
The aim of AncientAdhesives is to create the first reliable method to compare the complexity of Neandertal and modern human technologies. This is achieved through three main objectives:
1. Collate the first comprehensive body of knowledge on adhesives, including ethnography, archaeology and (experimental) material properties (e.g. preservation, production).
2. Develop a new archaeological methodology by modifying industrial process modelling for archaeological applications.
3. Evaluate the development of adhesive technological complexity through time and across species using a range of explicit complexity measures.
By analysing adhesives, it is possible to measure technological complexity, to identify idiosyncratic behaviours and to track adoption and loss of complex technological know-how. This represents a step-change in debates about the development of behavioural complexity and differences/similarities between Neanderthals and modern humans.

Summary Linear Parameter-Varying (LPV) systems are flexible mathematical models capable of representing Nonlinear (NL)/Time-Varying (TV) dynamical behaviors of complex physical systems (e.g., wafer scanners, car engines, chemical reactors), often encountered in engineering, via a linear structure. The LPV framework provides computationally efficient and robust approaches to synthesize digital controllers that can ensure desired operation of such systems - making it attractive to (i) high-tech mechatronic, (ii) automotive and (iii) chemical-process applications. Such a framework is important to meet with the increasing operational demands of systems in these industrial sectors and to realize future technological targets. However, recent studies have shown that, to fully exploit the potential of the LPV framework, a number of limiting factors of the underlying theory ask a for serious innovation, as currently it is not understood how to (1) automate exact and low-complexity LPV modeling of real-world applications and how to refine uncertain aspects of these models efficiently by the help of measured data, (2) incorporate control objectives directly into modeling and to develop model reduction approaches for control, and (3) how to see modeling & control synthesis as a unified, closed-loop system synthesis approach directly oriented for the underlying NL/TV system. Furthermore, due to the increasingly cyber-physical nature of applications, (4) control synthesis is needed in a plug & play fashion, where if sub-systems are modified or exchanged, then the control design and the model of the whole system are only incrementally updated. This project aims to surmount Challenges (1)-(4) by establishing an innovative revolution of the LPV framework supported by a software suite and extensive empirical studies on real-world industrial applications; with a potential to ensure a leading role of technological innovation of the EU in the high-impact industrial sectors (i)-(iii).

Summary Novel sophisticated technologies that exploit the laws of quantum physics form a cornerstone for the future well-being, economic growth and security of Europe. Here photonic devices have gained a prominent position because the absorption, emission, propagation or storage of a photon is a process that can be harnessed at a fundamental level and render more practical ways to use light for such applications. However, the interaction of light with single quantum systems under ambient conditions is typically very weak and difficult to control. Furthermore, there are quantum phenomena occurring in matter at nanometer length scales that are currently not well understood. These deficiencies have a direct and severe impact on creating a bridge between quantum physics and photonic device technologies. aQUARiUM, precisely address the issue of controlling and enhancing the interaction between few photons and rolled-up nanostructures with ability to be deployed in practical applications.
With aQUARiUM, we will take epsilon (permittivity)-near-zero (ENZ) metamaterials into quantum nanophotonics. To this end, we will integrate quantum emitters with rolled-up waveguides, that act as ENZ metamaterial, to expand and redefine the range of light-matter interactions. We will explore the electromagnetic design freedom enabled by the extended modes of ENZ medium, which “stretches” the effective wavelength inside the structure. Specifically, aQUARiUM is built around the following two objectives: (i) Enhancing light-matter interactions with single emitters (Enhance) independent of emitter position. (ii) Enabling collective excitations in dense emitter ensembles (Collect) coherently connect emitters on nanophotonic devices to obtain coherent emission.
aQUARiUM aims to create novel light-sources and long-term entanglement generation and beyond. The envisioned outcome of aQUARiUM is a wholly new photonic platform applicable across a diverse range of areas.

Summary Massive stars play many key roles in Astrophysics. As COSMIC ENGINES they transformed the pristine Universe left after the Big Bang into our modern Universe. We use massive stars, their explosions and products as COSMIC PROBES to study the conditions in the distant Universe and the extreme physics inaccessible at earth. Models of massive stars are thus widely applied. A central common assumption is that massive stars are non-rotating single objects, in stark contrast with new data. Recent studies show that majority (70% according to our data) will experience severe interaction with a companion (Sana, de Mink et al. Science 2012).
I propose to conduct the most ambitious and extensive exploration to date of the effects of binarity and rotation on the lives and fates of massive stars to (I) transform our understanding of the complex physical processes and how they operate in the vast parameter space and (II) explore the cosmological implications after calibrating and verifying the models. To achieve this ambitious objective I will use an innovative computational approach that combines the strength of two highly complementary codes and seek direct confrontation with observations to overcome the computational challenges that inhibited previous work.
This timely project will provide the urgent theory framework needed for interpretation and guiding of observing programs with the new facilities (JWST, LSST, aLIGO/VIRGO). Public release of the model grids and code will ensure wide impact of this project. I am in the unique position to successfully lead this project because of my (i) extensive experience modeling the complex physical processes, (ii) leading role in introducing large statistical simulations in the massive star community and (iii) direct involvement in surveys that will be used in this project.

Summary To successfully complete secondary education, persistent learning behavior is essential. Why are some adolescents more resilient to setbacks at school than others? In addition to actual ability, students’ implicit beliefs about the nature of their abilities have major impact on their motivation and achievements. Ability beliefs range from viewing abilities as “entities” that cannot be improved much by effort (entity beliefs), to believing that they are incremental with effort and time (incremental beliefs). Importantly, ability beliefs shape which goals a student pursues at school; proving themselves (performance goals) or improving themselves (learning goals). The central aims of the proposal are to unravel 1) the underlying processing mechanisms of how beliefs and goals shape resilience to setbacks at school and 2) how to influence these mechanisms to stimulate persistent learning behavior.
Functional brain research, including my own, has revealed the profound top-down influence of goals on selective information processing. Goals may thus determine which learning-related information is attended. Project 1 jointly investigates the essential psychological and neurobiological processes to unravel the longitudinal effects of beliefs and goals on how the brain prioritizes information during learning, and how this relates to school outcomes. Project 2 reveals how to influence this interplay with the aim to long-lastingly stimulate persistent learning behavior. I will move beyond existing approaches by introducing a novel intervention in which students experience their own learning-related brain activity and its malleability.
The results will demonstrate how ability beliefs and goals shape functional brain development and school outcomes during adolescence, and how we can optimally stimulate this interplay. The research has high scientific impact as it bridges multiple disciplines and thereby provides a strong impulse to the emerging field of educational neuroscience.

Summary This project is an interdisciplinary study of the role of indigenous knowledge in the making of science. Situated at the intersection of history and anthropology, its main research objective is to understand the transformation of information and practices of South American indigenous peoples into a body of knowledge that became part of the Western scholarly canon. It aims to explore, by means of a distinctive case-study, how European science is constructed in intercultural settings.
This project takes the book Historia Naturalis Brasiliae (HNB), published in 1648 by Piso and Marcgraf, as its central focus. The HNB is the first product of the encounter between early modern European scholarship and South American indigenous knowledge. In an encyclopedic format, it brings together information about the natural world, linguistics, and geography of South America as understood and experienced by indigenous peoples as well as enslaved Africans. Its method of construction embodies the intercultural connections that shaped practices of knowledge production in colonial settings across the globe, and is the earliest example of such in South America. With my research team, I will investigate how indigenous knowledge was appropriated and transformed into European science by focusing on ethnobotanics, ethnozoology, and indigenous material culture.
Since the HNB and its associated materials are kept in European museums and archives, this project is timely and relevant in light of the growing concern for the democratization of heritage. The current debate about the societal role of publicly-funded cultural institutions across Europe argues for the importance of multi-vocality in cultural and political processes. This project proposes a more inclusive interpretation and use of the materials in these institutions and thereby sets an example of how European heritage institutions can use their historical collections to reconnect the past with present-day societal concerns.

Call Details Starting Grant (StG), SH5, ERC-2018-STG
Summary Constructing Age for Young Readers (CAFYR)
CAFYR starts from the observations that Europe has recently witnessed a few pertinent crises in intergenerational tension, that age norms and ageism frequently go unchecked and that they are part of children’s socialization. It aims at developing pioneering research for understanding how age is constructed in cultural products. CAFYR focuses on fiction for young readers as a discourse that often naturalizes age norms as part of an engaging story and that is endorsed in educational contexts for contributing to children’s literacy, social and cultural development. The effect of three factors on the construction of age in children’s books is studied: the age of the author, the age of the intended reader, and the age of the real reader.
CAFYR aims to lay bare whether and how the age and aging process of children’s authors affect their construction of the life stages in their works. It will show how various crosswriters shape the stages in life differently for young and adult readers. It considers the age of young readers as varied in its own right, and investigates how age is constructed differently for children of different ages, from preschoolers to adolescents. Finally, it brings together readers of various stages in the life course in a reception study that will help understand how real readers construct age, during the reading process and in dialogue with each other. CAFYR also aims to break new theoretical and methodological ground. It offers an interdisciplinary approach that enriches children’s literature research with concepts and theories from age studies. It combines close reading strategies with distant reading and tools developed for digital text analysis. It provides a platform to people of different stages in life, contributing to their awareness about age, and facilitating and investigating dialogues about age, with the aim of ultimately fostering them more.

Summary Homogeneous catalysis is of prime importance for the selective synthesis of high added value chemicals. Many of the currently available catalysts rely on noble metals (Ru, Os, Rh, Ir, Pd, Pt), which suffer from a high toxicity and environmental impact in addition to their high cost, calling for the development of new systems based on first-row transition metals (Mn, Fe, Co, Ni, Cu). The historical paradigm for catalyst design, i.e. one or more donor ligands giving electron density to stabilize a metal center and tune its reactivity, is currently being challenged by the development of acceptor ligands that mostly withdraw electron density from the metal center upon binding. In the last decade, such ligands – mostly based on boron and heavier main-group elements – have evolved from a structural curiosity to a powerful tool in designing new reactive units for homogeneous catalysis.
I will develop a novel class of ligands that use C=E (E=O, S, NR) multiple bonds anchored in close proximity to the metal by phosphine tethers. The electrophilic C=E multiple bond is designed to act as an acceptor moiety that adapts its binding mode to the electronic structure of reactive intermediates with the unique additional possibility of involving the lone pairs on heteroelement E in cooperative reactivity. Building on preliminary results showing that a C=O bond can function as a hemilabile ligand in a catalytic cycle, I will undertake a systematic, experimental and theoretical investigation of the structure and reactivity of M–C–E three membered rings formed by side-on coordination of C=E bonds to a first-row metal. Their ability to facilitate multi-electron transformations (oxidative addition, atom/group transfer reactions) will be investigated. In particular, hemilability of the C=E bond is expected to facilitate challenging C–C bond forming reactions mediated by Fe and Ni. This approach will demonstrate a new conceptual tool for the design of efficient base-metal catalysts.

Summary What did politicians sound like before they were on the radio and television? The fascination with politicians’ vocal characteristics and quirks is often connected to the rise of audio-visual media. But in the age of the printed press, political representatives also had to ‘speak well’ – without recourse to amplification.
Historians and linguists have provided sophisticated understandings of the discursive and aesthetic aspects of politicians’ language, but have largely ignored the importance of the acoustic character of their speech. CALLIOPE studies how vocal performances in parliament have influenced the course of political careers and political decision making in the 19th century. It shows how politicians’ voices helped to define the diverse identities they articulated. In viewing parliament through the lens of audibility, the project offers a new perspective on political representation by reframing how authority was embodied (through performances that were heard, rather than seen). It does so for the Second Chamber in Britain and France, and in dialogue with ‘colonial’ modes of speech in Kolkata and Algiers, which, we argue, exerted considerable influence on European vocal culture.
The project devises an innovative methodological approach to include the sound of the human voice in studies of the past that precede acoustic recording. Adapting methods developed in sound studies and combining them with the tools of political history, the project proposes a new way to analyse parliamentary reporting, while also drawing on a variety of sources that are rarely connected to the history of politics.
The main source material for the study comprise transcripts of parliamentary speech (official reports and renditions by journalists). However, the project also mobilizes educational, satirical and fictional sources to elucidate the convoluted processes that led to the cultivation, exertion, reception and evaluation of a voice ‘fit’ for nineteenth-century politics.
Summary
What did politicians sound like before they were on the radio and television? The fascination with politicians’ vocal characteristics and quirks is often connected to the rise of audio-visual media. But in the age of the printed press, political representatives also had to ‘speak well’ – without recourse to amplification.
Historians and linguists have provided sophisticated understandings of the discursive and aesthetic aspects of politicians’ language, but have largely ignored the importance of the acoustic character of their speech.
