Leader's Profiles

Our workshop leaders are all highly experienced Diploma teachers, coordinators, and examiners. They are all approved by the regional office in Geneva.

The small size of our workshops means that the leaders are able to give participants individual attention, and our lively social programme enables the leaders to get to know participants outside the formal classroom setting.

Some leaders are from St.Clare's itself whilst others may be 'returners' who having moved on in their careers, relish the opportunity to revist Oxford and the College. Each year we also welcome many leaders from IB schools around the world. This ensures a truly international mix of leaders and participants at our workshop events.

Christos HalkiopoulosCPsychol AFBPsS

A philosopher by interest, a psychologist by training and a teacher by happy coincidence, Christos has been teaching IB Psychology at St Clare’s since 2003. He holds a BSc in Psychology from UCL (University of London) and specialised in Organisational Psychology at Birkbeck College (University of London) where he obtained an MSc in Occupational Psychology. The British Psychological Society (BPS), of which Christos is a member, has awarded him the title of Chartered Psychologist for his contribution to psychology teaching and relevant publications and the title of Associate Fellow for his contribution to the practice of psychology. A BPS-Registered Coaching psychologist, he is also a member of the Association of Business Psychology (at Principal Practitioner Level).  In addition to teaching and practicing psychology, and for ten years also TOK, Christos is a published author. He co-authored the popular Pearson IB Psychology textbook and is currently busy writing for its second edition. Christos is closely connected to the IB.

An experienced examiner and frequent member of curriculum review teams, he is also an IB-trained Workshop Leader.  As a Workshop leader, Christos has delivered many Category 1, 2 and 3 Workshops to both beginner and experienced psychology teachers in the UK and abroad. In the last few years these included workshops in Oxford, Amsterdam, Florence, Berlin and Dubai. For seven years Christos was a staff development officer at St. Clare’s, a role he cherished as it gave him the opportunity to use his experience as an organisational scientist, psychologist and educator to devise many original and useful training sessions for the teaching staff, especially in the areas of internationalism and student motivation and welfare.  Every year, Christos uses his immense experience in teaching and practicing psychology to run seminars and courses in student motivation and well-being. In recent terms he has run, in the context of his CAS Psychology Club at St. Clare’s, one-to-one and group coaching sessions on student motivation (including procrastination), stress management and resilience training.

Apart from his inexhaustible enthusiasm for psychology teaching, and practice, Christos’ interest in art history takes him to galleries all over Europe and beyond and he tries to find plenty of time to devote to his guitar playing, countless (and mostly aimless) visits to the centre of Oxford and (his very favourites) ‘philosophising about nothing in particular’, ‘doing absolutely nothing’ and ‘reading dozens of jokes per day’ from books and on the net. He considers books of jokes an alternative introductions to psychology and he is telling his students as much.
