If we analysed Earth remotely over the past billion years, what would we see? Earth’s surface environments have changed dramatically through geological time. My research in sedimentary geology investigates how Earth's sedimentary systems and environments, the history of oxygen in Earth’s atmosphere and oceans, and life (microbes, animals, and plants) have co-evolved through time. I am particularly interested in Earth’s oldest reefs and coastal environments such as tidal flats before plants and animals evolved.
I completed my PhD in Earth Science at the University of Melbourne, a MSc in Earth Science at the University of Oregon, and a BSc at Colorado College in Geology.

Music
Dr Jacob Olley is a Leverhulme Early Career Fellow in the Faculty of Music. His current research project, ‘Debating Music in the Ottoman Press, 1876–1928’, focuses on discussions of music in Turkish-language periodicals during the final decades of the Ottoman Empire. The project seeks to understand how debates about music became a site for historical and social critique amongst Muslim intellectuals, and how they relate to broader global entanglements between Europe and Asia during the long 19th century. Before joining Cambridge, he was a research associate (2015–2020) on the digital publication project Corpus Musicae Ottomanicae: Critical Editions of Near Eastern Music Manuscripts, based at the University of Muenster in Germany. His PhD thesis (King’s College London, 2017) is a cultural history of notation systems in Ottoman music, focusing on the invention of modern Armenian (‘Hampartsum’) notation in the early 19th century. Before this, he did a BA and Masters in Ethnomusicology at SOAS. He has taught at King’s College London and the University of Kassel, as well as giving lectures and invited talks at various institutions. He has also spent extended periods in Istanbul, where he studied the Turkish language and the ney (reed flute).

Super-resolution microscopy, mechanobiology, biophysics
After completing a PhD in Physics at King’s College London in 2019, Dr Ruby Peters joined the lab of Professor Ewa Paluch at the Department of Physiology, Development and Neuroscience. Her doctoral research, whilst formally granted in the discipline of Physics, was highly interdisciplinary spanning the fields of cell biology, optics, computational biology and biophysics. She is a specialist in super-resolution microscopy: a family of closely related techniques that bypass the classical diffraction limit of light and allows for the visualisation of single molecules within cells. Specifically, during her PhD she developed a number of algorithms for the analysis of super-resolution datasets of the actin cytoskeleton during the human immune response. At the Paluch lab, she studies cell-shape control in the context of the nanoscale organisation and dynamics of the actomyosin cortex. Despite its importance, our understanding of cell-shape regulation remains limited, owing to the across-scales and across-disciplines nature of morphogenesis studies. By using state of the art microscopy and computational approaches, She aims to connect the nanoscale interactions that occur within the actomyosin cortex to the mechanical properties of the entire cell during fundamental cell-shape changes, thereby bridging the length scales gap from the nanoscopic to the microscopic.

Engineering
Dr Preethi Rajendram Soundararajan is currently working in the Engineering Department, focussing on decarbonising combustion in the aviation and energy sector. Prior to this, Preethi completed her PhD at CentraleSupélec, France (formerly Ecole Centrale Paris), with a focus on understanding and mitigating thermoacoustic instabilities encountered in high-performance engines. Preethi is a recipient of the Marie Skłodowska Curie Fellowship and Amelia Earhart Fellowship during her PhD.
Hydrogen is one of the key fuels for carbon-neutral air travel and has been the recent focus of both academic as well as industrial research. Being a highly flammable fuel, hydrogen is easy to burn but poses other challenges in terms of flame flashback and the formation of other pollutants, such as oxides of nitrogen. To tackle these problems, in her current research, Preethi is working closely with industrial partners in developing future low-carbon engines by performing experiments on lab-scale burners to determine the optimal injector configuration that can produce good mixing and flame stabilisation. She is also focussing on improving combustion efficiency by studying the mechanism of plasma-assisted combustion through lab-scale experiments.

Artificial Intelligence.
I am working as a research associate at the Leverhulme Centre for the Future of Intelligence. There, I am part of the Kinds of Intelligence Programme where I am working on the research project RECOG-AI (i.e., Robust Evaluation of Cognitive Capabilities and Generality in Artificial Intelligence).

Alan Turing had a vision. To create an ultimate test of a machine's ability to exhibit intelligent behaviour indistinguishable from that of a human. 70 years later, however, we are as far from understanding how to assess AI’s capacities as ever before. The main aim of our research project is to develop a novel AI evaluation framework based on the current understanding of cognitive capabilities in humans and animals, that assesses patterns of AI performance across multiple cognitively inspired tasks. Such an approach will allow us to make robust inferences about cognitive capabilities of AI. My research is specifically focused on developing novel suites of tasks and validating them on existing AI systems.

I recently completed my PhD in Cognitive Science at the Donders Institute for Brain, Cognition and Behaviour (The Netherlands). I also hold a M.Sc. in Language, Mind and Embodied Cognition from University of Edinburgh and a B.Sc. in Psychology from University of Ljubljana.

Mathematical Oncology
Low oxygenation, or hypoxia, is associated with cancer evolution, resistance to therapy and metastatic spread. Currently, the spatio-temporal relationship between vascular function and oxygen delivery in solid tumours is poorly understood, thereby hampering previous efforts to alleviate hypoxia or exploit it for therapeutic benefit. Paul’s research applies machine learning to photoacoustic imaging to facilitate the extraction of high-quality vascular features from living subjects. He applies the resulting data to advanced biophysical models which predict blood and interstitial flow, and transient oxygenation in whole tumours, in order to advance our fundamental knowledge of the mechanisms underpinning hypoxia fluctuations for improved therapeutic outcomes.

He is currently a Wellcome Trust Junior Interdisciplinary Fellow based in the Bohndiek Lab at the Cancer Research UK Cambridge Institute. He received his doctorate in Applied Mathematics from University College London, where he also completed a MRes in Mathematical Modelling in Healthcare Engineering. He completed my MSc in Applied Mathematics at Imperial College London and received a BSc in Mathematics from the University of Southampton.

Biochemistry
Dr Timmler is a neuroscientist with a background in biochemistry and molecular biology. His research focusses on myelin, the cellular structure that wraps around axons, the “cables” of the brain. He wants to understand how neuronal activity regulates myelin formation and how myelin influences the function of neuronal circuits. 

He studied biochemistry at the Martin-Luther-University Halle-Wittenberg and Christian-Albrechts-University Kiel in Germany, supported by a Cusanuswerk fellowship. During his PhD in the lab of Mikael Simons in Göttingen (Georg-August-University, MPI for Experimental Medicine) and Munich (Technical University, DZNE), he discovered that complexes of adhesion molecules cooperatively regulate myelin sheath growth. As a postdoc in the lab of Ragnhildur Thóra Káradóttir at the Cambridge Stem Cell Institute, he is now studying how neuronal activity changes patterns of membrane adhesion molecules to determine myelination. Recently, he secured generous funding through the Walter-Benjamin fellowship of the German Research Foundation (DFG). His main methods are light and electron microscopy, primary cell culture, optogenetics and proteomics. When he is not in the lab, he enjoys cycling through the English countryside, firing up the barbecue and gardening. You can follow him on twitter @MyelinScientist or researchgate.

Natural Science (Biological)
Behavioural flexibility allows animals to be responsive to their environment and to exert control over their social and physical worlds. My research uses multiple approaches to examine both how behavioural flexibility relates to underlying physiology, and to its adaptive function. From behavioural adaptations such as male advertisement song, to manipulative cuckoo calls and elaborate animal architecture, the questions I investigate are inspired by being a curious naturalist at heart. I am currently especially interested in the role that behavioural flexibility, and phenotypic plasticity more broadly, might play in the origins and maintenance of biodiversity. I mainly investigate these questions in wild birds including the white-browed sparrow weavers of the Kalahari desert, interactions between brood parasitic common cuckoos and their reed warbler hosts in the lush green Cambridgeshire fens, and most recently, the interactions between Diederik cuckoos and the African weaverbirds.
