Overview
I'm a university lecturer and astrophysicist working in the field of extra-solar planets. I am involved in the development of new missions and observatories to characterise the atmospheres of exoplanets, in particular the ESA Ariel mission, as well as Twinkle and the NASA EXCITE mission. I also am involved in cycle 1 and cycle 2 JWST exoplanet observations in collaboration with IoA Cambridge. I am interested in understanding atmospheric and planetary processes in temperate regime sub-Neptunes and gas giants, and how these relate to fundamental questions of planet formation and the diversity of the exoplanet population. I am also interested in astrobiology, particularly the potential for biospheres in temperate sub-Neptunes and gas giants, how we may be able to determine the frequency of life-bearing worlds (the fL factor in the Drake Equation) and how exoplanetary observations might be able to constrain theories of the origin of life.

Research
Research focus
- Development of new exoplanet observatories and missions
- Ariel: first large-scale spectroscopic survey of exoplanet atmospheres.
- I developed original versions of ExoSim/ArielSim observation simulator and Ariel Data Reduction Pipeline (ADaRP). I lead the Simulations Working Group and am involved in a number of other ground segment and science working groups. I am involved in the development of the Ariel data pipeline. I am Co-I on the UKSA Cardiff Ariel grant.
- EXCITE: first dedicated exoplanet phase-curve spectroscopy observatory and first balloon-borne exoplanet observatory
- NASA collaborator/co-investigator
- Twinkle: innovative UK-led space telescope for exoplanet spectroscopy
- Developed TwinkleSim simulator and contributed to performance estimations. Now a member of the Twinkle Science Team helping to shape the mission goals and science.
- Ariel: first large-scale spectroscopic survey of exoplanet atmospheres.
- Exoplanet atmospheric spectroscopy
- Sub-Neptunes:
- Co-I on JWST Cycle 1 GO program 2722:

- Temperate gas giants (with Luke Booth):
- Developing modeling and observational approaches to characterise this poorly-understood exoplanet population.

- Hot Jupiters:
- Developed JexoPipe pipeline for JWST and applied this to hot Jupiter spectra.
- Sub-Neptunes:
- Astrobiology
- DRAKE (Dedicated Research for Advancing Knowledge of Exobiology): a proposed space mission to find the frequency of life in the Galaxy using transit spectroscopy (see paper in MNRAS).
