The HSA Staff

Dr Huw Golledge BSc PhD - Chief Executive & Scientific Director

Huw became Chief Executive and Scientific Director of HSA and our sister charity, UFAW in January 2020.

 Prior to taking up the role he was Senior Scientific Programme Manager for the two charities, overseeing many of their scientific activities.

Huw originally studied biology at University College London and then completed a PhD in neuroscience at Newcastle University. During this time, he developed a concern for the welfare of animals used in scientific research and went on to undertake research in laboratory animal welfare, also at Newcastle University. He was a member of the Home Office Animals in Science Committee from 2013-2016.

Huw is a strong advocate of evidence-based animal welfare and it is this that initially drew him to work for the two charities.

He is assisted in his duties by Gerda, the Miniature Schnauzer and Pete the cat.

Outside of work he likes to spend his time in the outdoors, walking and taking photographs.


Dr Birte L Nielsen MSc BSc PhD - Assistant Scientific Director

Birte Nielsen joined the team in September 2020, bringing with her a wealth of experience and in-depth knowledge to the role as Assistant Scientific Director. During the past three decades, she has worked with rats, growing pigs, dairy cows, broiler chickens and broiler breeders, as well as horses, sows, laying hens and even ostriches, carrying out research in basic and applied ethology and animal welfare.

Her dedication to animal welfare has seen her travel from Edinburgh in Scotland, where she spent eight years, via Denmark to Paris, France where she worked on the links between olfaction, behaviour, and neuroscience. She has been a member of various expert panels and working groups, such as Chair of the Danish Animal Welfare Council. She is a former President of the International Society for Applied Ethology (ISAE), and was recently appointed Independent Chair of the Global Coalition for Animal Welfare (GCAW).

When not constrained by a global pandemic, Birte likes hill-walking (as a participant) and football (as a spectator).


Jane Moorman - Charity Secretary

Jane joined the staff in July 2013 having brought with her cover 25 years’ experience of working with the private and voluntary sector at a senior management level.

Her responsibilities include sound financial management and reporting, property management, legacy administration, contractual negotiations, Charity Commission and Company House compliance, and HR management and guidance.  On a personal level she was brought up in the Brecon Beacons and was an active member of the YFC.  Her links with that community still exist and she is never happier than when visiting friends on their farm.



Charles Mason HND MInstM CF ARAgS - Technical Director

Charlie grew up in the East Midlands, where his parents were in the licensed trade.  One generation removed from farming – his maternal grandfather was a tenant farmer before losing his sight – from an early age Charlie fed calves on the small dairy farm next door to his home and progressed to mixed farm work during the school holidays.  He studied general agriculture at Harper Adams, from where he graduated in 1980.  There followed eight years of milking cows and working with beef cattle and sheep, followed by livestock marketing in both the deadweight and live sectors.

This broad expertise led Charlie to the Humane Slaughter Association, where he has worked full time since 1988, starting as a Technical Officer and progressing to Technical Director in 2001.  Outside work, Charlie maintains a keen interest in farm livestock, being a member of the Rare Breeds Survival Trust and heavily involved with two local agricultural shows.  Charlie is a Member of the Institute of Meat, a Churchill Fellow of 1990 and an Associate Fellow of the Royal Agricultural Societies.


Luisa Dormer - Scientific Communications & Outreach Officer


Jade Spence BSc (Hons) MSc AMRSB - Technical Officer


Dr Susan Richmond BSc MSc PhD - Technical Officer

Susan grew up in a rural area of Fife. She graduated with a BSc (hons) in Biology and Psychology from the University of Stirling in 2009. These years were instrumental in developing her interest in animal behaviour and welfare. In 2010 she seized an opportunity to collect data on the behaviour of wild chimpanzees in Uganda. She returned to the University of Stirling to complete her MSc in Behaviour and Evolution looking at novel practical ways to assess the welfare of primates used in biomedical research. 

While studying in Stirling, Susan took the chance of a placement at Scotland’s Agricultural College/SRUC and The University of Edinburgh to gain experience with livestock. This led on to her PhD project Assessing the welfare of extensively managed sheep: an evaluation of animal-based welfare indicators, which she completed in 2015. 

In October 2015 Susan joined the HSA as a Technical Officer. Susan is particularly interested in helping to organise the HSA’s participation in agricultural shows and other events which engage with the livestock industry. She also undertakes welfare assessments and helps develop HSA guidance and online training materials.

She also enjoys gardening and watching football, especially champions Liverpool, and eating chocolate!
