Susan Mennenga

Susan E. Mennenga is a clinical researcher involved in multiple clinical investigations of psilocybin-assisted psychotherapy, with a focus on psychiatric and existential distress in patients with life‑threatening cancer and on therapeutic processes in alcohol use disorder. Her work, as represented in several clinical papers, emphasises both quantitative clinical outcomes (including reductions in loss of meaning, suicidality, anxiety and depressive symptoms) and detailed qualitative clinical interpretations of patient experience.

Mennenga has contributed to studies reporting acute and sustained reductions in loss of meaning and suicidal ideation following psilocybin-assisted psychotherapy in oncology populations, detailed individual case narratives from cancer patients, long-term follow-up outcomes, and analyses of personality change and clinical interpretation in a double-blind, placebo-controlled trial for alcohol use disorder. Her contributions are characterised by integration of clinical assessment, psychotherapy process evaluation, and patient-centred outcome measurement, advancing understanding of both therapeutic effects and subjective experience in contemporary psychedelic-assisted therapy trials.
