Prof Andy Gardner
School of Biology
PURE
Social Evolution, Cosmological Natural Selection, Anthropic Bias Andy works on Darwinian adaptation. Natural selection explains the appearance of design in the living world, but at what level is this design expected to manifest – gene, individual, society – and what is its function? And does Darwin’s logic extend outwith Biology, to concepts of cosmological natural selection and anthropic bias?

Dr Paul Savage
School of Earth & Environmental Sciences
PURE
Stable Isotope Geochemistry, Meteoritics, Planetary Differentiation Processes Paul studies the formation and evolution of rocky planets (with a focus on our own solar system), from tracing the sources and types of material involved in planetary accretion, to the subsequent differentiation of planets into silicate mantles, metallic cores, and volatile-rich atmospheres and hydrospheres. Paul’s main tools for this are the analysis of stable isotope variations in both terrestrial and extra-terrestrial samples.
Dr Kevin Scharp
School of Philosophical, Anthropological and Film Studies
PURE
Evidence and Explanation, Science and Religion, Origins of Life Kevin is interested in how discoveries about exoplanets affect our thoughts about the meaning of human life.

Dr Elyse Allender
School of Earth & Environmental Sciences
PURE
Planetary Science, Remote Sensing, Planetary Analogue Research, Image Analysis Elyse’s research at the University of St Andrews and Aberystwyth University focuses on the field and laboratory testing of the PanCam, ISEM, and CLUPI instrument emulators for the ESA/Roscosmos ExoMars rover, as well as the development of software tools which will exploit the wealth of visible and near-infrared data generated by these instruments and further their utility for detecting evidence of past habitability on Mars.
Dr Eleanor Mare

Deep Nitrogen Cycle Atmospheres are essential for planetary habitability. Our atmosphere has changed a lot since life first evolved, but we don’t know exactly how. Eleanor studies nitrogen (the main gas in air), because the atmospheric mass might have changed if nitrogen was gradually taken up by, or released from, the solid Earth.

Thorsten Balduin
School of Physics & Astronomy
MC ITN CHAMELEON
Grain charges and lightning in disks The thermo-chemical state of circumstellar disks determines the composition of planets that form in them, and is hence the key to understand exoplanet diversity. Particularly important here are the physico-chemical conditions in the midplane inside of ~10 au, where most planets form. These regions are very difficult to observe and hence the conditions in these regions are largely unknown. It is the aim of this project to establish to what extent the mechanism known to cause lightning in the Earth atmosphere also works in protoplanetary disks, and how these processes change disk observations and the preconditions for planet formation. Thorsten is working with Peter Woitke as part of the MC ITN CHAMELEON “Virtual Laboratories for Exoplanets and Planet-Forming Disks”.

Katharina Bernhard
School of Philosophical, Anthropological and Film Studies
Epistemology, Philosophy of Science, Social Epistemology of Science, Scientific Expert Testimony Katharina’s research revolves around epistemological goings-on in scientific expert testimony (SET). Some of the questions she is trying to answer are: What is epistemically required for SET to be successful? How can inductive risk considerations play an epistemically legitimate role in communicating scientific results? What epistemic challenges for SET arise from various forms of uncertainty characteristic for (most) scientific research?

James Hitchcock
School of Physics & Astronomy
GravityCam lucky-imaging microlensing survey James’s research focuses on high-resolution optical imaging, and the image processing methods which allow us to accurately measure the brightness of stars in very crowded environments.

Ancy Anna John
School of Physics & Astronomy
Exoplanet observations Ancy is working with Andrew Cameron on improving the sensitivity of radial-velocity surveys to low-amplitude planet signals. She will be developing new methods of separating Doppler shifts caused by orbital motion from apparent shifts caused by spectral line-shape variability caused by stellar activity. In this way we aim to enhance the accuracy and precision with which masses of transiting super-earths and mini-Neptunes from TESS and CHEOPS can be recovered using HARPS-N. Ancy has a World-Leading St Andrews Scholarship from St Leonard’s Postgraduate College.
Till Käufer
School of Physics & Astronomy
MC ITN CHAMELEON
Machine learning from complex disk models Spectral features emitted in the near and mid infrared by molecules from the surface of protoplanetary disks in principle allow us to determine the temperature and chemical composition of the gas in the planet-forming regions. The project combines the expertise in modelling such molecular emission lines from protoplanetary disks with new machine learning techniques developed in the exoplanet community. Till’s aim is to train AI systems on the spectra, with those AI systems then quickly predicting the emergent line emission spectra as function of the physical input parameters like element abundances, temperature profile, UV irradiation, dust/gas ratio, etc. Till is working with Peter Woitke as part of the MC ITN CHAMELEON “Virtual Laboratories for Exoplanets and Planet-Forming Disks”.
Ethan Landes
School of Philosophical, Anthropological and Film Studies
Applied Epistemology, Philosophy of Science Ethan is interested in applied epistemology. Paying attention to specific academic fields or specific instances of our ignorance, he investigates which sorts of things we can know given our evidence. Recently Ethan has been thinking about the particularly tricky case of astrobiology. Do we know what alien life is like, given that we’ve never seen any?
Emma Puranen
Interdisciplinary Doctoral Scholar
School of Modern Languages, School of Biology, School of Physics & Astronomy
Turning science fiction into data science What happens when we treat books as data? Can literary theory ever meet scientific standards? By applying a range of historical and current methods of quantitative analysis to a body of science fiction, this project will investigate claims for objectivity in literary theory. The project will focus on science fiction about exoplanets. A central question for the St Andrews Centre for Exoplanet Science and this project is how would human society respond to life beyond our planet. Emma is working with Emily Finer, V. Anne Smith and Christiane Helling. Emma has a World-Leading St Andrews Scholarship from St Leonard’s Postgraduate College.

Jan-Philip Sindel
School of Physics & Astronomy
Formation of cloud condensation nuclei in exoplanet atmospheres The atmosphere of an exoplanet is the window in its present state but also its past. Almost every exoplanet observed so far has cloud that hinder our view into the deeper atmosphere. This project therefore explores how cloud particles form in exoplanet atmospheres under chemical conditions that are very different from Earth. The project utilises quantum-chemical simulations to study the formation of metal-oxide clusters as recourses for extrasolar cloud-condensation nuclei. Jan-Philip will work with Christiane Helling, and he is a St Leonard’s Global Doctoral Scholar in collaboration with the KU Leuven (Belgium).
