Dr Paul Rimmer
I work on exoplanet and brown dwarf atmospheres and try to answer some simple questions at the edge of the origin of life and chemical evolution. My main interests:
How do cosmic rays charge the atmosphere? What role do cosmic rays play in the climate?
Bridging equilibrium and non-equilibrium chemistry in the atmosphere: What does lightning do to chemistry, and what definite chemical tracers exist for lightning?
Answering these questions will involve cosmic ray transport calculations and chemical kinetics modeling that includes cosmic ray and X-ray ionization, FUV photochemistry and shock-driven chemistry.

I have a diverse research experience in electromagnetics and plasma physics including astrophysical applications. I am interested in electrification of brown dwarf atmospheres, lightning discharges there and radio emission from brown dwarfs in a contest of retrieving information on magnetic fields and processes in the atmospheres. I am working on modelling cyclotron radio emission from brown dwarfs in order to get an insight into global magnetic fields configuration and strength there as well as to look for signatures of discharges affecting it (propagation effects). I also do modelling of radiation from lightning discharge, including effects from ionized regions of atmosphere surrounding the discharge.
Dr Craig R. Stark
My research interests are broadly within the field of theoretical plasma physics, the modelling of plasma phenomena and its astrophysical application. I received my PhD at the University of Glasgow where I studied plasma processes in pulsar environments, including the growth of spheroidal dust grains via plasma deposition. At the LEAP project I was applying plasma processes and collective effects associated with gas discharges in planetary atmospheres populated with dust.
