Following a PhD at the University of Warwick, James went on to train as a clinical psychologist at Salomons, Canterbury Christchurch University College. Between 2008 and 2012, James was an Academic Tutor on the Oxford Doctoral Course in Clinical Psychology.

Elspeth Twigg BSc, MSc
Research Lead

Ellie started working for CORE IMS in 2010, although she has been involved with CORE one way or another for almost 10 years. Before the days of CORE IT systems she was one of the original team of researchers who worked at the Psychological Therapies Research Centre (PTRC) at Leeds University, the birthplace of the CORE System. Here she manually scanned clients' forms to generate service reports, dealt with enquiries from practitioners and wrote academic papers.

While at Leeds, Ellie completed an Open University degree followed by an MSc in Applied Statistics. Her MSc project was the development of the YP-CORE measure (for young persons), which remains a particular area of interest.  When PTRC closed in 2008, she began work as a freelance Research Consultant and remained involved in many CORE projects.

Ellie acts as Research Lead on various projects within CORE IMS, as well as supporting services by undertaking data analysis for them. She also works on sector-specific benchmarks and has produced benchmarks for the Higher Education sector and updated Primary Care benchmarks.


Simone Cross MSc (CTA)P UKCP & EAP Reg. Psychotherapist
Training Development Lead

Simone has worked clinically in a diverse range of mental health settings including a NHS Adult Community Health Team and a Personality Disorders Counselling Service. In response to working with clients diagnosed with Borderline Personality Disorder and who also satisfied the criterion for cluster A and C personality disorder, Simone developed an interest in the value of questionnaire feedback as a means of providing feedback on client progress to the clinician.

Simone's interests focus on the clinical application of questionnaire feedback, which focuses on change at the individual item level, rather than summary score level, as a means of enhancing client involvement in therapy and maintaining a collaborative approach when it is important to focus on small steps.

In her role with CORE IMS Simone is supporting the development of training to support therapists in making the best clinical use of outcome monitoring. She is also involved in the development and maintenance of a CORE User online community.


Angelika Meachen
CORE Net Implementation Manager

Before joining CORE IMS, Angelika worked as a Quality Manager on the EAP side of a large private healthcare provider.

After initially doing a degree in English Literature and Linguistics, Angelika first developed an interest in psychology when she worked as a lecturer in the Adult Education sector. She completed a Diploma in Post Compulsory Education with the Open University and focused on the psychological aspects of adult learning.

After having worked for several years as a professional trainer, she joined a provider of Employee Assistance Programmes and developed a role in project management across the company. She first became involved with CORE when she project managed the roll out of CORE PC and subsequently CORE Net to the entire EAP's UK network of counselling affiliates and therapists. Since her responsibilities also included the EAP's ISO 9001 accreditation, she introduced the use of CORE outcome data as a means of monitoring organisational effectiveness and evaluating practitioner performance. The role of data in change management and their impact on organisational growth remain a key interest.
