I graduated with a D.Phil. from the University of Basel, Switzerland in 1967. My doctoral thesis supervisor was Prof. Dr. T. Reichstein, (Nobel Laureate 1956). I was the Director of Clinical Laboratories at the Addiction Research Foundation (ARF) from 1971 to May 1995. We provided Biochemistry, heamatology and toxicology services. The toxicology laboratory at ARF was responsible for providing a 24hour/7days emergency identification of drugs including alcohol for almost 80 hospitals in the metropolitan of Toronto.  We also provided interpretation support for in-house drug and alcohol treatment and rehabilitation programs. To the best of my knowledge, ARF Lab was the largest toxicology laboratory in Canada.

In June 2000, I was appointed as a consultant and in Laboratory Medicine in the Department of Clinical Pathology, Sunnybrook Health Science Centre and in 2008 a Research Associate in the Sunnybrook Research Institute.

Since May 1995, I am with the Division of Clinical Pharmacology and Toxicology, The Hospital for Sick Children in Toronto. I joined this program as a scientist and a consultant in toxicology after leaving ARF. From August 2001 to November 2005, I was responsible for the direction of the toxicology laboratory at the St. Michael’s Hospital in Toronto. I was a consultant in toxicology with Canadian Medical Laboratories from 1997 to 2013.

As Inspector for Forensic Urine Drug Testing, American College of Pathologists I have participated in inspections of laboratories requesting certification to do Work Place Drugs of Abuse testing. I have attended ILO (International Labour Organization, UN, Geneva) sponsored Tripartite (Governments, Employers and Labour) meetings in Geneva and Oslo as WHO’s expert in Workplace Drug Testing.

As a scientist I have developed “Point of Care” devices for Ethanol, Methanol, Acetaminophen, and Salicylate to be used in the emergency room or clinical laboratory in triaging these poisonings. (the latter two have received approval for sale from Health Canada and the European Common Market).My other credits include coauthoring a book titled Alcohol and the Identification of Alcoholics, invention and patent of an alcohol dipstick, a computer software program CBAC: Computerized Blood Alcohol Calculator, and book chapters on drugs of abuse.  

My research interests have been in the biochemical changes in the alcohol and drug using population and pharmacokinetics in the drug abusing population

I am a Fellow of The Royal Society of Chemistry (UK), Academy of Clinical Biochemistry (USA) and Canadian Academy of Clinical Biochemistry (CAN).Enter information here
