    I am a native English speaker and fully trained science teacher, with the necessary qualifications and classroom experience. I also have two years ICT teaching experience so have a solid grasp of the MS-office suite. I have a strong background in academic, technical and content writing. Obviously my preferred area is science taken as a whole, (in particular Earth, Space and applied science), however my postgraduate qualifications focused on the place of science in society and how to communicate the subject to a variety of audiences, so a strong emphasis on social science and the structural aspects of science communication. In addition I can write and research a whole host of subjects ranging from history, politics and international relations to music, food and literature. I am able to research, assimilate and communicate primary research papers and demonstrate commitment, diligence and attention to detail whatever the task may be. Most importantly, I don’t apply if I don’t think I can do the job. I have 10 years fundraising, administration and communications experience in the charity, not for profit sector have worked on behalf of just about every UK/NGO or campaigning organisation you can think of. Finally I have approximately 5-10 years office, administration and telephony experience in the corporate sector.  less
