Research interests

Aqueous alteration in primitive extraterrestrial materials: I study the geochemical and isotopic properties of hydrated carbonaceous chondrites (CO, CM, CY, CI and C-ungrouped meteorites) and fine-grained micrometeorites. They are samples of water-rich asteroids and their study allows us to explore the interaction between rock and water across a range of geochemical environments. By investigating primitive hydrated bodies we seek to understand fundamental early geological processes that operated on minor bodies during the age of accretion and planet-building, approximately 4.5 billion years ago. This topic lies at the forefront of modern research interests, directly informing current and upcoming space missions (including OSIRIS-REx, Hayabusa2, DAWN, ROSETTA, Comet interceptor and DESTINY+).

Developing fossilized micrometeorites as a new atmosphere and climate proxy: Alongside colleagues at the Natural History Museum and Imperial College London we are pioneering the use of fossil micrometeorites as a new proxy to infer changes in the composition of Earth’s atmosphere over geological time. Cosmic dust grains fall to Earth continuously. During their passage through the atmosphere they are flash heated, melted and oxidized. A small fraction survive to the surface and eventually become preserved in sedimentary rocks, forming “fossil micrometeorites”. Analysis of these ancient extraterrestrial materials provides insights into the compositional diversity of the asteroid belt whilst also providing a means of indirectly inferring the composition of Earth’s upper atmosphere in the past. In particular micrometeorites could be used as a tool to reconstruct former CO2 and O2 levels at key periods in Earth’s history.  

The geological diversity of comets: Comets are balls of rock and ice that formed in the outer regions of the early solar system. Their primitive compositions preserve insights into the reservoirs from which matter condensed, the accretion behaviour of solids at large heliocentric distances and the origin of water and volatiles. Today, comets originate from two source regions – an inner ring extending from the orbit of Neptune out to ~1000 astronomical units (AU), referred to as the Kuiper Belt and an outer spherical zone (>10,000 AU from the Sun), referred to as the Oort Cloud. Despite decades of research we still know little about the composition and internal structure of comets nor do we know how much variation exists among comet populations. Are there different compositional types of comets and if so, what can these types tell us about the structure of the protoplanetary disk? I aim to tackle this question by combining telescopic observations of distant comets with microanalysis of rare cometary dust grains.

My research output includes 48 publications in peer-reviewed journals (19 first-authored) and >65 conference contributions as well as a range of online and print science communication articles. A full list of my journal publications can be found on Google scholar.

Teaching interests

I am module team chair for our level 2 practice science course: SXPS288: Remote experiments in physics and space
I am also deputy chair for our level 2 planetary science course: S283: Planetary science and the search for life
I am a module team member for S350: Evaluating contemporary science

I am currently studying as an OU student for a Post Graduate Certificate in Academic Practice (PGCAP).

Impact and engagement

My research has been featured in the New Scientist, Astronomy magazine, BBC radio Kent, ASU News, Zeiss and several other online articles. I have also written science communication articles for The Conversation, Evidently Scientifical (I, II & III), Diamond LightsourceImperial College London and Science Trends. Today I am involved in the use of micrometeorites, collected from urban environments (e.g. rooftops, gutters, road sweepings etc.) as an engagement resource. The ability to rapidly recover and confidently identify cosmic dust from easily accessible sites opens a new avenue of planetary science to the public. Urban micrometeorites have huge potential for citizen science and educational projects as demonstrated by the work of Jon Larsen (Project Stardust), Scott Peterson, Dr Thilo Hasse and Dr Sarah Roberts. In collaboration with micrometeorite hunters we aim to develop this topic as an inspiring access tool in STEM subjects.

Using cosmic dust from ancient sediments to investigate the geology of asteroids and their role in supplying nutrients to Earth
RoleStart dateEnd dateFunding source

Asteroids are small rocky objects formed early in the solar system’s history. They are remnants left over from the age of planet formation, more than four billion years ago. Today asteroids reside in a region of space between the orbits of Mars and Jupiter. Collisions between asteroids are rare but when they happen, they release huge quantities of dust into space. Some of this dust is captured by Earth’s gravity and falls to the surface. This cosmic dust can become locked up in sedimentary rocks on the ocean floor. Scientists can search sedimentary rocks, reconstructing a record of asteroid collisions that occurred many millions of years ago as well as exploring how the composition of the asteroids and how dusty collisions events affected life on Earth. In this research project I will study 8-million-year-old Italian sediments looking for dust from a major asteroid group known as the Veritas family. Analysing these dust grains will tell us new information about the composition of asteroids and whether these objects could have acted as important sources of water for the early Earth. In addition to learning more about the asteroid belt, this project explores the hypothesis that collisions between asteroids can have a profound effect for life on Earth. This is because asteroid dust can bring important nutrients to Earth, helping life to thrive in the nutrient-poor regions of our vast oceans. This project uses rocks found on Earth to look beyond our planet and learn more about the early solar system.
