I provide editorial services for academic and educational publishers, professional bodies and charitable organisations. I specialise in STEM resources.

Project Manage

I manage all or part of the publishing process, from concept to camera-ready copy. I assemble great teams of associates and freelancers and create manageable working schedules.

Edit & Proof

I work as an editor, proof reader or both. I check the flow of text, identify gaps in content and ensure there’s a consistent structure. I also write succinct and catchy copy.

Design & Draw

I design and layout pages with thought and creativity while adhering to style guides. I research photos, brief illustrators, or draw diagrams myself.

About me


I am Mark Gadd. I have a range of resource creation and publishing skills – I can manage, develop, design, write, edit, research and typeset. I’m happy to get involved at any stage, from concept through to camera-ready copy.

I have helped create countless resources, including textbooks and revision guides, digital content and websites, classroom activities, lesson plans, schemes of work, workshops and activities for events. Some were self-published under the 4science brand, others were managed on behalf of publishers and other clients.

I live in Brighton with my wife, Ellie, and our two kids, Oscar and Albert, and work in a friendly shared-office with views towards the sea.

I have an extensive list of associates and freelancers to help with larger projects, including authors, editors, proof readers, designers and web builders.

My dad, Ken, was the owner of 4science. Now retired after 40-odd years working in education, he still provides me with curriculum and technical advice.


A selection of projects and organisations I have worked with.


A few nice words from some of my clients…

“ Mark produced a high quality set of primary school resources for us on the subject of mosquitoes and how to avoid being bitten. He was extremely organised and thorough, producing everything to the timescales agreed.  He also has creative flair, and designed some fantastic games and activities using the scientific information we provided, sourcing great cartoons and illustrations too. We would definitely recommend and work with him again.”

Vickie Bazalgette – LSHTM

“ I worked with Mark for more than five years, commissioning him to develop STEM project resources for CREST Award Scheme. Mark’s pro-active approach to generating ideas has helped us accelerate CREST developments, and form new partnership opportunites. Mark is highly professional and personable, maintaining the fine balance between efficiently delivering high quality work, with making business enjoyable. 

Jodie Isle, British Science Association

“ 4science produced a high quality set of teaching resources for us which included video and lesson plans.  Mark managed the project, which included sourcing individuals to profile, the writing and audience testing of lesson materials and arranging subcontractors to deliver the filming.”

Nicola Hannam, The Science Council 

For around 20 years, 4science created educational resources, and provided consultancy and training. As the focus has shifted to resource creation for publishers, 4science has gradually morphed to become EditorialMark.
