Dr Hannah Mossman

Senior Research Fellow (Secondment)

Senior Lecturer, Manchester Metropolitan University

About me

I have always loved the seaside and always loved science, but never imagined I could have a job that combined both! After my undergraduate degree in Biological Science at Kings College London, I worked as Research Assistant on fish and rivers, and this is where I really got the research bug. I started my PhD in saltmarsh restoration at University of East Anglia in 2003 and have worked on coastal saltmarshes ever since.

After finishing my PhD and working on several research projects as a post-doc, I moved to Manchester Metropolitan University as a Lecturer in Ecology in 2013. I am passionate about teaching the importance of restoring the natural world to students, and love communicating my science to wider audiences. I have also continued my research into saltmarshes, investigating their biodiversity and more recently how much carbon they can store.

My role

I’ve been working with the WWT since 2014, when my colleagues and I started to research the development of WWT Steart Marshes and how much carbon it could store. Since that time my relationship with WWT has grown, and early in 2024 I started a secondment to the Conservation Evidence Team as a Senior Research Fellow.

My role is really exciting as I get to work on all things saltmarsh! I’m currently working on the Saltmarsh Code and developing a saltmarsh research strategy, as well as advising on many aspects of saltmarsh restoration and management.
