Dr Carol Treasure

Dr Carol Treasure

Co-Founder & CEO

I started my career in the pharmaceutical industry and then backpacked around the world for about a year, including a 3-month expedition to Zimbabwe with Operation Raleigh. I still believe that travel is the best education! After that I was ready for Uni and studied Physiology & Pharmacology at Sheffield. Having witnessed animal testing I knew that there had to be a better way – not just ethically, but scientifically too. So when I got the opportunity to do a PhD at FRAME (Fund for the Replacement of Animals in Medical Experiments) at the University of Nottingham, I jumped at the chance. My academic career involved the development of reconstructed human skin models for non-animal testing.

I then spent 7 years with a small US-based company called Cascade Biologics. This role gave me the wonderful opportunity to live and work in Portland, Oregon for a couple of years. We provided human cell culture systems to scientists all over the world. I set up and ran the European operation from 2003-2007, which provided very valuable commercial experience. I co-founded XCellR8 with Bushra in 2008. My role as the Managing Director spans both the scientific and commercial aspects of the company and provides an exciting and diverse job which I am very passionate about. In 2013, I finally settled down and got married! I live in the beautiful Cheshire countryside with my husband Russell and our menagerie of pets. I love the “country life” and still love to travel and pursue my love of photography. In my spare time I teach meditation and mindfulness, and enjoy a variety of activities including swimming, cycling, running and yoga.

Bushra Sim

Bushra Sim

Co-Founder / Technical Director

Having over 20 years’ experience in cell culture, I started at the Royal National Orthopaedic Hospital in Stanmore, London, researching osteoblast (bone cell) characterisation and differentiation. I later moved to the University of Nottingham where I was involved with establishing the cell culture laboratory for the Biomaterials Group within the School of Biomedical Sciences.

Seeking fresh challenges, I left academia in 2003 and stepped into industry where I spent 4 years at Cascade Biologics (Mansfield, UK). It was a diverse role which included culturing a wide range of human primary cell types and providing technical support to customers across Europe.

Even more exciting and challenging now is being part of XCellR8. My role is mainly laboratory based – which involves performing GLP regulatory and non-GLP contract studies to evaluate skin and eye irritation and corrosion, using reconstructed human tissue models, and cytotoxicity using human primary cells for cosmetic products and ingredients.

Outside work I enjoy a wide variety of outdoor activities including rock climbing, abseiling, hiking as well as adventure travel – not to mention fitness work using the urban rebounder, better than the gym!

Susie Lee-Kilgariff

Marketing director

I spent my early career working for a variety of advertising agencies, including McCann Erickson where I helped put Next on TV for the first time.

After my first daughter was born, I crossed over to the dark side and worked within marketing teams for professional services and financial businesses, rising to marketing director for SaaS provider Sorted Group and winning awards for branding and campaign effectiveness along the way. I became a consultant to combine my passion for marketing with the flexibility to be there for sports days.

I work with SMEs in the B2B arena, specialising in brand strategy, lead generation and business development. I believe that language is the most important thing we have, which is handy when your job is all about great communication.

At weekends, I’m usually found in the Lake District, hiking, wild swimming and enjoying cream teas. I’m also a founder member of the Knutsford Bake Club and once appeared on Masterchef.

Strategic advisor – finance

I started my working life as a management accountant at the Aga Group before moving to an even larger PLC, Invensys, for three years across a number of group roles. In 1999 I moved to Capital Safety Group, the market leader in fall protection manufacture, where a few years later I became the youngest divisional finance director at 29, looking after the EMEA region.

In 2014 I decided to rethink my work life balance and work part time. After helping Dantec (a VC owned composite hose manufacturer) through a successful exit to a German trade buyer, I now work with a number of smaller SMEs to pass on my experience and help them raise funding and grow, while maintaining profitability.

I know a lot about cosmetics because I have a 13 year old daughter! I play golf and 5 a side football to stay fit and enjoy travelling particularly in the pursuit of wildlife spotting.

Strategic advisor – HR

I am a HR and OD professional, initially gaining my experience working with AstraZeneca Pharmaceuticals. I worked alongside several senior leadership teams, supporting key projects around business transformation. I developed an excellent track record in facilitating organisational change, new team start up and coaching leaders to drive real improvements in business performance.

In 2013, I started my own company and since then have really enjoyed working with a wide variety of great people and companies, not least XCellR8. My focus is always on improving team effectiveness and keeping an organisation’s focus on what will add the most value. I demonstrate a relentless belief in the possible, great intuition about people and my high personal resilience and enthusiasm is often infectious.

When I’m not busy working, I am lucky to have a fabulous family and three gorgeous children who keep me very busy! Having grown up in the beautiful Peak District, I love the outdoors so will often drag them with me to get outside and explore our beautiful countryside.

Dr Terry McCann

Dr Terry McCann

Strategic advisor – technical

I have more than 20 years’ business leadership experience, supporting business development & providing business consultancy services to small & large enterprises within the life science & drug discovery.

After a career in academia, in 1997 I joined the management team of a small scientific instrument company that was acquired by PerkinElmer in 1998. In various business leadership roles I managed annual sales of up to $40M, driving growth >20% p.a.

In 2004 my wife and I changed our careers and went travelling for 15 months. We volunteered on four wildlife conservation projects (in Nicaragua, Kenya, Brazil, and Mongolia) and travelled around each of these regions.

Since 2005 I have been fully occupied with TJM Consultancy, serving the needs of our diverse clients. I also contribute to scientific debate through journal and conference contributions, and since 2014 I have written the Lush Science Prize background paper, which supports the judging panel in identifying potential recipients of the prize.

I live up a mountain in southern Spain, with my wife, our dog, and her tortoise (who she’s known for a lot longer than she has me!).

Chris Longmore

Chris Longmore

Scientific Account Manager

My introduction to life sciences began with a Bachelor’s degree in Biochemistry from the University of Liverpool, followed by a Master’s degree from the same institution. During this time, I also completed a research internship at the Faculty of Medicine in Chulalongkorn University, Thailand.

In my first year as a graduate, I worked as a market research consultant in the science and technology sectors, allowing me to work with a number of companies hoping to develop exciting projects. Through this I met XCellR8, where the commitment and mission of the company enthused me to not only return to a role in the laboratory, but join them in developing an exciting new range of in vitro tests.

Having spent several years working as a scientist, I was promoted to Scientific Account Manager in 2019. I now use the experience I gained in the the lab to advise clients on how to develop their animal-free testing strategies and explain how our technologies work.

Away from the lab I can be found telling awful jokes or making a mess with paint and brushes. Despite living in Liverpool for a number of years, I remain behind enemy lines as a staunch supporter of Chelsea FC.

Executive PA

I have over a decade’s experience in providing support at a senior and board level. I’m super-organised with the ability to juggle a variety of tasks from booking travel, scheduling and attending meetings, managing a very busy diary, project managing an office and lab relocation and supporting the growth of XCellR8.

Before joining XCellR8 I worked for a global charity, working within the marketing team which allowed me the opportunity to develop my writing skills. I also implemented an internal communications strategy which was adopted across the group and delivered an award-winning marketing campaign. Earlier in my career, I spent several years working in recruitment after completing an HND in Media and Journalism.

I’m definitely someone who is always on the go and loves spinning a million plates. That’s why working as an Executive Assistant for Carol is so fantastic; no two days are the same. The ethics of the company are extremely important to me and we have some inspiring values that everyone in the team embraces.

I’m also a mum to an active 10-year-old who is aiming to be the next Steven Spielberg, a volunteer with a local scouts group and regularly attend Zumba.

With most of my career spent in the telecommunications industry, I have spent the last few years in the life science sector. My role concentrates on supporting the operations side of the business. I am pleased to be part of the XCellR8 team who have such passion and dedication to their work, which I share!

As administrator to the team, my role is to support the company infrastructure, ensuring everything is needed and catered for on a day to day basis, keeping the business operating as successfully and efficiently as possible.

Time away from the office is spent with my family and travelling in my much loved VW Camper ‘Rosy’.

Ana Quevedo

Ana Quevedo

Technical Sales Manager

I joined XCellR8 in November 2020, after a decade spent in technical sales for the pharma and personal care industries in Latin America and contract research organisations for the cosmetic and personal care sector in Europe (mainly Spain, Germany, France and Switzerland). Over the last 5 years, I have developed a keen interest in cosmetics formulation, testing methods and sustainable beauty, which helps when I am partnering with clients to help them develop their safety and efficacy testing strategies. As a biologist, I always like to keep up to date with innovative scientific research.

I speak both Spanish and English, and have wide experience of the regulatory environment in western Europe as well as South America for organisations bringing new or reformulated cosmetic ingredients and products to market

I like to learn about new topics, trends and new scientific research approaches. This is why I identified with XCellR8’s innovative R&D programme so much. I am excited about a future when conventional in vitro test methods are entirely free of animal derivatives.

In my spare time, I like hiking and biking in the countryside, spending Sunday mornings reading, watching comedy movies and baking. In the summer, I love spending beach time with my husband and daughter.

Scientific Team

Dr Fiona Jacobs

Dr Fiona Jacobs

Senior Scientist

I turned my lifelong curiosity in all things scientific into a degree in Biochemistry from the University of Sheffield. I followed this with a PhD which focussed on elucidating the biochemical activity of previously uncharacterised proteins involved in cancer. This not only gave me great experiences using in vitro investigative techniques but showed me, first-hand, how cell-culture provides relevant and robust models for human systems.

I then completed a post-doctoral research project at the University of Liverpool, where I used transcriptomics to identify druggable targets in rare ocular melanomas; this further developed my
experimental cell-culture and data analysis expertise.

I joined XCellR8 in 2017, having been inspired by our ethos and 100% animal-product free approach. My role involves planning and supervision of both regulatory and non-regulatory studies, analysing data and interpreting this into information relevant to sponsors. I’m still invigorated by the team’s dedication to producing ethical, robust high-quality data day-in, day-out.

In my spare time I attend weekly Spanish language lessons with my husband. I also enjoy exploring the beautiful Cheshire countryside, especially visiting the many local ice-cream parlours.

Scientist II

From a young age I have always had a keen interest in science, which led me to studying for my undergraduate master’s in biochemistry at the University of Leeds.

During my time at Leeds, I completed research in a potential antiviral therapy, from which I was introduced to cell culture and molecular biology, skills that I was keen to develop outside of academia. The passion and vision of XCellR8 instantly captured my attention, and our drive to redefine testing made me want to be a part of the team.

This is one of the aspects of why I enjoy working at XCellR8 as I get to collaborate with like-minded individuals and help develop ways to constantly improve. 

Outside of work I enjoy spending time with family and friends and travelling.

Scientist II

By nature, I have always enjoyed a good puzzle; the more difficult the problem the more interested I would become. I was fascinated by the complexity of life at the molecular level and quickly decided to pursue a degree in Biochemistry at the University of Huddersfield. My time at University fostered a real passion for practical research, I quickly became hooked and if I wasn’t in a lecture hall there’s a good chance I was experimenting in the lab!

My work in In Vitro Toxicology began shortly after University where I joined one of the world’s largest CROs. After approximately 10 months I assumed responsibility for all In Vitro Tox. Lab operations. As my experience grew I became more involved with validation work and R&D projects.

Being in the industry I knew of XCellR8. I was impressed by XCellR8’s commitment to R&D and shortly after became aware there was an opening for an experienced Scientist. Throughout the interview process the passion for animal-free testing and continually promoting better science really stood out to me and I decided to join XCellR8 in 2020. 

Outside of work I enjoy sports and I like to keep fit, if only to continue playing football at a good level. I’m always up for an adventure and like exploring the world around us.

It was a course at the City of Liverpool College that ignited my passion for biology and gave me a newfound interest in biochemistry, which I decided to pursue with an undergraduate degree at the University of Liverpool. My research involved looking at the role of pseudokinases in certain forms of leukaemia and allowed me to acquire many practical skills in cell culture and molecular biology, skills which I further developed throughout my master’s degree.

It was after a shopping trip to Lush that I first heard of XCellR8’s work. Realising how many non-animal testing methods are available, and how they are more reliable and valid relative to their animal equivalents, I was inspired to join the team and help contribute to our mission to end all animal testing.

As a scientist at XCellR8, my day to day activities involve testing a variety of chemicals using the animal-free assays that we offer. Since the assays are so varied and no two products are the same, each day is different and offers exciting challenges – one of the many reasons I enjoy working here so much.

In my spare time I stay active through boxing and weightlifting. I am also a keen guitar player who loves performing and listening to a wide range of genres.

Quality Assurance Manager

When AstraZeneca in Cheshire announced a reduction in its R&D footprint, I took it as an opportunity for a career change. With over 20 years’ experience as a GLP QA Auditor in the pharmaceutical industry, and an MSc in Quality Management of Scientific Research and Development I was not expecting to find similar work locally.

When I saw an advert for a GLP QA role in the cosmetic testing, personal care and household cleaning industries I was naturally curious, and delighted to be invited for interview with Carol to hear about the service XCellR8 provides to these industries.

I left totally captivated by XCellR8, the passion to replace animal-based product testing and the cutting edge science being conducted to achieve this. I so wanted to contribute to this, and haven’t stopped smiling since Carol rang and offered me the position nearly six years ago!

Outside of work I enjoy spending time with family and friends, pottering in the garden, and embarrassing my teenage daughter by ‘mum dancing’ when we go to watch her favourite bands. I am also the original ‘crazy cat lady’ and have two Ragdoll cats (but there’s always room for more).

Thomas Hand

Thomas Hand

Quality Assurance Officer

After having a love for the biological sciences instilled in me during high school (thanks Mr Davies!), I went on to a degree in Molecular and Cellular Biology at the University of Huddersfield. During my degree I spent a year working for Covance at their Harrogate site, learning the ropes of genetic toxicology and Good Laboratory Practice (GLP).

After completing my degree, I spent a further 6 years working to Good Clinical Practice (GCP) as a scientist for hVIVO in London, a company that pioneered the Human Viral Challenge Model (HVCM). I eventually made the switch to QA and spent a further 3 years at hVIVO, adding experience in the General Data Protection Regulation (GDPR) as Data Protection Officer to my GLP and GCP experience.

I joined XCellR8 in 2019 as QA Officer, wanting to be back to GLP, to play my part in achieving 100% animal-free testing and to grab the opportunity to join a close-knit team.

My spare time is spent with my wife and two children, when I am not cycling around the countryside or watching football, F1, rugby or any sport going on TV.

Eileen Edwards

Eileen Edwards

Laboratory Assistant

I have 30 years’ experience of working in science laboratories. My first role was with Golden Wonder as a Laboratory Technician and I then went on to work for Jeyes as a Research and Development technician. I wanted to work closer to home, so I moved to a High School in Widnes as a Senior Science Technician where I stayed for 14 years.

This is where I found my love of teaching. I started to teach forensic science in both the high school and with seven of our feeder primary schools. This led me to start up my own business in 2014 delivering curriculum science, forensic science and fun science, to a number of primary schools within the North West. I received the Gratnells ‘Technician of the year’ award in 2011.

At XCellR8 I work as a Laboratory Assistant, supporting the scientific team by keeping the laboratory organised and helping with the administrative and clerical work associated with our work. I love the ethos of the company and feel very privileged to be part of this fast moving and exciting environment. Outside of work, I enjoy spending time with my family, friends and my two cats. I also enjoy travelling and walking.

Sally-Anne Conway

Sally-Anne Conway

Laboratory Technician

I have had an interest in all things science from a young age, which lead to me completing a bachelor’s degree in biology. Along with life sciences I also have a passion for the world of cosmetics and skincare; this opened my eyes to the importance of ethical animal-free testing
techniques being readily available.

My position as Lab Technician allows me to play an important role in supporting the scientists and activities here at XCellR8. I get to be involved in both the operational and scientific side of life in the lab, where every day is different and exciting. I am proud to say that I work at a pioneering company, where everybody is striving towards the same goal of making animal-free testing the global standard.

When I’m not in the lab you’ll find me at home, researching the latest skincare and makeup tricks, spending time with my family and friends, and picking up a paintbrush every now and again.
