**Significant disruption alert!** Due to planned major downgrades to pensions of academic staff, members of the University and College Union have voted overwhelmingly to take strike action starting on 22 February at many universities around the country.

Lecturers never want to disrupt students' degrees, and as such strike action is always a last resort. But the magnitude of what's at stake and unnecessary and unreasonable nature of the proposals has led to this situation.

You can read more about the reasons for the dispute here. Those who want more context should read this excellent article by Waseem Yaqoob of Cambridge University.

I am a University Teacher in the School of Mathematics and Statistics at the University of Sheffield, and also Communications Officer for the University of Sheffield branch of the University and College Union. I can be found in room G9 of the Hicks Building.

I've been at the University of Sheffield since 1999, first as an undergraudate then as a PhD student of Neil Strickland. Since 2009, I have been employed by the School of Mathematics and Statistics in a teaching-focussed role.

I was part of a team which introduced a flipped approach to our Level 1 engineering teaching in September 2013, based around videos and active small-group sessions. The implementation was highly successful, and resulted in a Senate Award for Collaborative Activities from the University of Sheffield and a runner-up place in the Teaching Excellence category of the 2015 Guardian University Awards.

I am also interested in developing a broad skills base for our students, and was involved in the creation and subsequent delivery of our Mathematical Investigation Skills module, which introduces first-year students to programming, web-design and mathematical writing, and has proven to be popular and well-received.

In the 2017-2018 academic year I am involved with the following courses.

- MAS114: Numbers and Groups (Semester 2)
- MAS115: Mathematical Investigation Skills
- MAS140/151/152/156/161: Engineering Mathematics
