Research services include:
  - Research collaboration.
  - Research supervision, including at Masters and Doctoral levels.

Emerging from my research, teaching and practice, I have generated and explored new theory and praxis concepts, including:
  • "environ-mentalization" - an ability involved in the development of the ecological self; promoting empathy with our environment; thinking about the environment's experience of itself (Sibbett, 2003, 2017). A development of Fonagy's concept of mentalization;
  • "nettlesome knowledge" a form of difficult or troublesome knowledge that encompasses those “elements of knowledge that are deemed taboo in that they are defended against, repressed or ignored because if they were grasped they might ‘sting’ and thus evoke a feared intense emotional and embodied response” (Sibbett, 2007; Sibbett & Thompson, 2008, p.229). However, if grasped, "nettlesome knowledge" can act as a threshold or portal to new knowledge and opportunity, offering a transformative experience (Sibbett, 2007);
  • "secondary liminality" - or "vicarious liminality", as experienced by psychotherapists / healthcare practitioners in working with clients experiencing liminality, such as when diagnosed with cancer or during life-threatening illness (Sibbett, 2004, 2005);
  • liminality in Art Psychotherapy and in cancer experience  (Sibbett, 2004, 2005);
  • heterotopic space in Art Psychotherapy (Sibbett, 2004, 2005);
  • flow experience in Art Psychotherapy (Sibbett, 2004, 2005);
  • play experience in Art Psychotherapy (Sibbett, 2004, 2005);
  • eARTherapy - eco-practice in Art Psychotherapy (Sibbett, 2003, 2017).
