About Marc

My name is Marc Cleiren (1961).  I’m a psychologist. I work as an associate professor at the Honours College of Leiden University (Social Sciences Department). I also develop and research intake procedures for prospective students of the university. My current focus area of research is on the developmental journey of young people from entry in the academic environment toward study success, acknowledging the broad array of aptitudes and cultural diversity. On a practical level, I am working as talent coach and a teacher of academic skills.

My favorite teaching and research subjects are the quest for meaning, dealing with loss and grief, consciousness development, the development of communication skills, and the role of group processes in development. I published several books and scientific articles on these subjects (see Core publications).

I lecture and organize workshops in the field of motivation, identity development and communication skills. Over the past 30 years, I have been training professionals and university students on the subject of hands-on talent development, and working with motivational discrepancies. I have developed train-the-trainer curriculums and have taught psychological coaching skills to intercultural groups at the Leiden University Institute of Psychology.

As a guest lecturer on personal development, I work at the School of Governance of Utrecht University (Master Strategic Management, a two-year, part-time Master’s program for managers).

‘Authentis’ refers (of course) to authenticity. My one-man company was set up to cover the application of my knowledge and experience outside academia. In the Netherlands and abroad, I lecture and give workshops on subjects dealing with the development of existential meaning and major life events. In these areas, I have conducted research, as well as provided professional training for societal and policy institutes (e.g. the World Health Organization, Dutch Ministry of Health, Welfare and Sport, the Netherlands Kidney Foundation, National Foundation Bereavement). Together with Stefan Tax, I have developed organization-wide mission and vision articulation for high-profile cultural organizations (Museum Boymans van Beuningen, Rotterdam; Museum Volkenkunde, Leiden) and developed a ground-breaking method (REAL Research) for teaching scientific research skills in a experiential training context.
