Sunny Bains teaches research, analysis, argument, writing, and presentation to more than 1000 engineers and physical scientists annually at UCL (University College London). She also created and runs the minor in Strategic Thinking in Engineering and Technology, teaches a module in Tech Journalism and is the Editorial Director of UCL Engineering Inspiration. In 2019 she lead the Association of British Science Writers Science & Technology Journalism Summer School, the content partly inspired by the mistakes that lead to the Theranos scandal. She won a Provost’s Teaching Award in 2016, and is a Senior Fellow of the Higher Education Academy.

Because she regards a technical background as being important for good science journalism, in 1999 she founded a course at the University of California at Berkeley called Writing for the Technical Press. Taught through the College of Engineering, the course was only open to students doing science and engineering degrees. She subsequently ran the undergraduate communication and professional skills programme in the Electrical and Electronic Engineering Department at Imperial College London.

She has also participated in several external educational projects, including consulting on a website for a National Endowment for Science Technology and the Arts (NESTA) project to encourage young-teenaged girls to do physical sciences or engineering: Planet Jemma (Flash 6 is required). She has also run short courses for member organisations (such as SPIE: The International Society for Optics and Photonics) and for private companies.
