Dr. Douglas Rees BSc (Hons) PhD MRSNZ, Founder and Chief Scientific Officer, Aqix Ltd UK


Doug Rees Douglas Rees became an Elected Member of the New York Academy of Sciences in 1981 for research studies published (1972-4) on motor nerve terminal metabolism during his Rockefeller Post-Doctoral Fellowship at the University of California (1970-73). In 1973-78 he was appointed Muscular Dystrophy Research Fellow, tenable in the Institute of Neurology, Southern General Hospital, Glasgow, where the development of AQIX® RS-I was initiated using human cadaver nerve-muscle tissue biopsies. In 1978 he was appointed Senior Lecturer in Neurophysiology, Wellington Clinical School and Victoria University, New Zealand.

He became Head of Research and Development and Consultant Physiologist of Res-Del Ltd, New Zealand (1980), and implemented his research into the preservation of human organs for transplant based upon his knowledge and internationally published research in physiology, neurophysiology, pharmacology and biotechnology. His contribution to organ preservation research over two decades and appointment as Patron of the New Zealand Muscular Dystrophy Association in 1988, led to his election as a Member of the Royal Society of New Zealand in 1997.

His research led him to invent the means of keeping animal and human organs alive outside of the body which culminated in the patented design of the Res-Del® Isolated Tissue/Organ Perfusion System (1980) and the development of the AQIX® RS-I Preservation and Perfusion medium, which he went on to successfully patent (2000) and manufacture.

He had early on recognized the revolutionary impact AQIX® RS-I would have for medical applications in human biotechnology as well as drug bioassay and in the advancement of organ transplant technology.

This breakthrough in physiological research was greatly ahead of its time and has been recognized as such by International Patents. However, it took the remarkable qualities of the AQIX® RS-I, a simulated interstitial fluid, for his discoveries to be embraced by global pharmaceutical companies.
