Academic leader of the S4 project

Professor Mary Gagen

As S4’s geography and natural science lead, Mary is a Professor of Physical Geography and researches climate change. Mary works in ancient forests around the world to find out what they can tell us about how our climate has changed in the past, and how it might change in the future. She is also passionate about science education and the communication of environmental science. Mary loves being outside hiking, swimming, surfing or pottering about looking at new rocks and trees!

Outreach Bioscientist

Alicia Petersen

Alicia, a Swansea native, is a keen lover of animals and all things nature, and a passionate film fan. When not reeling off animal facts, or chatting about film, Alicia is passionate about dancing and a keen vegan baker.

AAT Finance Administrator

Michela Finnis

As S4’s Finance Administrator, and a keen ultra-marathon runner, Michela is used to tough jobs! Michela oversees all finance operations for the project. If she isn’t hanging out with her daughter, two cats and Scotsman, you can find her running a very long way around the South Wales coast, reading, watching reruns of Star Trek or lost in a True Crime podcast. Michela is fluent in Italian, and as an AAT Level 3 qualified and licensed bookkeeper has her own business working with small independent local businesses.

Academic leader of the S4 project

Dr Will Bryan

Will is an experimental physicist and S4’s academic lead on physical science. Will is originally from Essex, coming to Wales in 2007 after completing a physics degree and PhD at University College London. His research involves using very short pulses of laser light to make electrons for imaging microscopic motion, and finding new uses for lasers such as evaporating bits of trees to measure the chemical composition of wood. When not lasering things, Will lectures in physics, is co-lead of S4, and contributes to Oriel Science. Away from work, he enjoys cycling, painting and DIY, although not simultaneously.
