Jolyon Mitchell


I am a private consultant specializing in the laboratory evaluation of orally inhaled products (OIPs) of all types. I was Scientific Director of Trudell Medical International until September 2013, with responsibility for all aspects of in vitro aerosol testing. I am involved in several industry-wide organizations involved with inhaled medical aerosol delivery, in particular the European Pharmaceutical Aerosol Group (EPAG) as well as serving as a Scientific Adviser to the International Pharmaceutical Aerosol Consortium on Regulation and Science (IPAC-RS).

I was appointed to the Expert Committee: General Chapters – Dosage Forms (GC-DF) of the United States Phamacopeial Convention for the 2010-2015 term, renewed for the 2016-2020 term where I now chair the Aerosols sub-committee to the GC-DF Committee.

I am a Fellow of the UK Royal Society of Chemistry, and both a Chartered Scientist and Chemist. I am a founder and since 2015, an honorary life member of the UK-Irish Aerosol Society. I am also, a member of the Gesellschaft für Aerosolforschung, American Association for Aerosol Research, American Association of Pharmaceutical Scientists (Inhalation Technology Focus Group). I am an adjunct professor at the University of Western Ontario since 2004. I am also an affiliate professor at the Daniel K. Inouye College of Pharmacy of the University of Hawaii at Hilo from September 2013, where I have taught a course on Drug Delivery by the Inhalation Route to Pharm.D. and Ph.D. students. I have also been a faculty member for the annual International Society for Aerosols in Medicine (ISAM) Aerosol School, held under the leadership of Professor Myrna Dolovich in Hamilton, Ontario, since its inception in 2009.

I have published more than 500 articles in the open literature, of which about 160 are in peer-reviewed journals and 12 are invited review articles. I have also contributed to seven books on aerosol science, writing chapters concerned with aerosol measurement techniques, the calibration of aerosol measurement equipment and inhaled medications for the older patient. I am co-editor of a book entitled: “Good Cascade Impactor Practices, AIM and EDA for Orally Inhaled Products”, published in May 2013 by Springer, NY.
