Expert medico – legal opinion : CV/Bio

These commentaries are based on Dr Gillman’s peer reviewed scientific papers, see Publications

Expert opinions

I only undertake analysis of opinions given in difficult cases where my expertise in the circumscribed areas specified below, in which I am considered a leading international authority, are of importance or relevance.  I do not do routine medico-legal work or clinical assessments of patients for medico-legal reports.

My fee for consultations and reports is AU$750 per hour, for a minimum fee of AU$4,500, for up to six hours work.

Current professional status

  1. Principal investigator and director at ‘PsychoTropical Research
  2. Chairman of the presiding council of the International MAOI expert group,
  3. Author of many published peer-reviewed research analyses on the above topics

My team and I publish papers in my areas of special expertise in the peer-reviewed scientific literature (see below).

I am regarded as being among the leading world authorities on serotonin toxicity, monoamine oxidase inhibitor (MAOI) antidepressant drugs and related topics.

I do pro bono work related to medical and patient education about psychotropic drugs via my website, videos, accredited seminars, and online consultations.

Brief CV/Bio

I graduated in 1974 from Guy’s Teaching Hospital medical school (London, UK) and undertook postgraduate study, specialist training, and clinical experience at Guy’s medical school and associated hospitals.  For six years, until 1981, I was training, and doing clinical practice, pharmacology research (see publications) and, latterly, teaching at Guy’s Hospital.

Qualified as a specialist in 1981 (MRCPsych UK)

1981-83:  Southampton University teaching hospital, latterly consultant psychiatrist on the professorial unit; previously, academic lecturer and senior registrar, professorial unit, Southampton University teaching hospital.  In charge of post-graduate education and the academic program, planning and advising on clinical research, and supervision and tutoring of specialists in training.

Moved to Australia June 1983

1983-2006: Private practice, in Mackay, Queensland

Visiting specialist Mackay Base (public) hospital 1983-1987

1985-2006: Director, psychiatric in-patient unit Pioneer Valley private hospital, general adult psychiatry.

For some years I practiced as the only specialist in this regional centre (population ~100,000).  I had extensive experience of dealing with a large workload entailing assessment and management responsibility 24/7 for patients on a wide variety of treatments including electroconvulsive therapy, monoamine oxidase inhibitors and all other forms of psychotropic drugs.  I also set up and managed two inpatient psychiatric units at private hospitals, which included the teaching and supervision of medical assistants, psychologists, pharmacists, occupational therapists, and nursing staff.

I provided consultation services to the police, including attendance at firearms sieges, attempted suicides, etc.

I continue to undertake medico-legal consultations and reports in my areas of special expertise.

I ceased medical patient-care practice in 2006 because of a medical problem causing hand-writing and keyboard-work difficulties.

Postgraduate teaching and website

I have taught at a postgraduate level throughout my career, teaching doctors, psychologists, pharmacists, etc.  Also, for more than twenty years I have maintained (and continue to maintain), on a pro bono basis, a website providing critical analysis of neuro-pharmacology research and expert information concerning drugs, drug interactions, serotonin toxicity and related subjects, and educational resources.  These are all for the benefit of both doctors and patients.

My website is internationally recognised for its excellence by both doctors and patients, who contact me from around the world for advice.

I held an adjunct (honorary) senior lecturer (Psychiatry) post at James Cook University, Townsville, Qld (relinquished as of 2006).

I continue to provide seminars and lectures to universities, teaching hospitals, professorial departments worldwide.

Research publications in scientific journals

I have more than 100 contributions to the scientific literature across the fields of pharmacology and psychiatry, predominantly relating to serotonin toxicity and MAOIs, related to side effects, drug interactions, and toxicity.

I have internationally recognised expertise in MAOIs, serotonin toxicity (aka serotonin syndrome), TCAs, hyper-thermic syndromes, and neuroleptic malignant syndrome.

Research publication information

A typical principal investigator, or professor, at a prestigious research university will have ~1,000 citations and an ‘H-index’ of ~14 (see e.g., Google scholar).  I have an H-index of 28 and a cumulative total of more than 4,500 citations.  I have about fifteen major single-author review papers that have been extensively cited (between 100-500 times); I am in about the 99.9th percentile of authors in the field of neuro-pharmacology, i.e., the top 0.1 percent of authors.

2006 to present: Academic work

I am widely recognised as a leading international authority on serotonin toxicity and monoamine oxidase inhibitors (MAOIs).  I have provided independent reviews and legal opinions in relation to such matters, in the UK, USA, and in Australia.

I am the founder and convener of the International MAOI Expert Group; I am also the chairman of its presiding council.

Under my guidance and chairmanship this group has published influential position statements and papers concerning the use of MAOI drugs [1, 2].

I am an invited expert-participant in the Malignant Hyperthermia Association of the US (MHAUS) expert group.

I act as an occasional referee for various journals.

Most of my publications concern human clinical neuro-pharmacology, with particular reference to drug mechanisms of action and effectiveness, interactions between drugs, and toxicity.

Most of my scientific publications are referenced in the NLM database

Google scholar also lists my references [and current citation totals].  My scholar profile is public.

Recent major review papers

I have produced a large body of original research analyses, mostly concerning serotonin toxicity, MAOIs and TCAs.  Most of my major papers are single-author review papers published in journals of high prestige and impact; they have been extensively cited (in the top 1% of all cited papers, see link to ‘Google Scholar’ above).

The list below of some 80 contributions to the literature is largely comprised of recent review papers, and other salient publications.

Consider Donating to PsychoTropical

PsychoTropical is funded solely through generous donations, which has enabled extensive development and improvement of all associated activities. Many people who follow the advice on the website will save enormously on doctors, treatment costs, hospitalization, etc. which in some cases will amount to many thousands of dollars, even tens of thousands — never mind all the reduction in suffering and the resultant destruction of family, work, social, and leisure capability. A donation of $100, or $500, is little compared to those savings. Some less-advantaged people feel that the little they can give is so small it won’t make a difference – but five dollars monthly helps: so, do not think that a little donation is not useful.
