was born in Wexham (near Slough) in May 1986. I decided
at any early age that I wanted to follow palaeontology as
a profession, thanks largely to many trips to the natural
history museum and a full collection of the Dinosaurs! weekly
magazine, and joined first Rockwatch then the Palaeontological
Association. I spent my work experience helping out Andy
Ross in the arthropod department of the Natural History
Museum and In 2004 went to the University of Birmingham
to study Geology with Biology, graduating in 2007. I studied
for my Master's in Palaeobiology at the University of Bristol,
and it was there that I first became interested in eurypterids,
graduating with a distinction in 2008. Since then I have
done odd bits of work (including exam marking for NFER)
and continue to work on papers. I am currently studying for a
PhD at the University of Kansas with Paul Selden, continuing my work on arthropod phylogeny and looking at patterns of selection across extinctions.
palaeontology my interests include travel, ancient and medieval
history, fiction writing and reading. I have a love for
nature in all its forms, instilled in me from my parents,
and take an active interest in conservation and general
is a list of my publications to date. To view an abstract
