Current Work – Reproduction and fertility in birds.

University of Sheffield

n.hemmings@shef.ac.uk

Originally from West London, I came to Sheffield to study for my undergraduate degree in 2003 and never left. In 2007 I joined the Birkhead lab as a PhD student investigating the causes of hatching failure in birds. After finishing my PhD in 2010, I spent a year as a University Teacher before embarking on my current post-doctoral position. In addition to my research, I currently teach part of APS126 Behaviour of Humans & Other Animals (Level 1), APS135 Skills for Biologists (Level 1), and APS347 Cooperation & Conflict (Level 3) and co-supervise a number of undergraduate and PhD students. In 2011 I won Animal & Plant Sciences Teacher of the Year.

I have a broad interest in behavioural ecology and reproductive biology. Most of my research focuses on reproductive behaviour and physiology of birds – I am particularly interested in the mechanisms of sperm selection, storage and transport within the female reproductive tract. I am also interested in the causes of reproductive failure in birds, and have published a number of papers on this subject that can be found below. This work has significant implications for the conservation of endangered species, which I recently discussed in UK Parliament at the SET for Britain Awards.

In addition to my research, I love talking to people about science and getting them excited about it! I am involved in a number of widening participation and public engagement initiatives: I organise public visit days for the department’s Alfred Denny Museum where the public can enjoy free, guided tours. I have also coordinated interactive exhibition sessions for the last five years, as part of the department’s annual Christmas time lecture, which attracts approximately 1000 local school children. I run a rolling outreach training scheme for undergraduate students, helping plan activities, teaching how to run effective sessions and setting up links with target schools. I am also involved in the department’s excellent Outreach Program and have given numerous talks and workshops as part of larger public engagement events organised by the University. In 2014 I was awarded the Society of Biology Science Communication Award (Established Researcher Category).
