Faculty Bios

Myrna Dolovich is Professor of Medicine (Part-time) in the Faculty of Health Sciences, McMaster University, Hamilton, Ontario and associated with the Firestone Institute of Respiratory Health. She is an Electrical Engineer (McGill University, 1963) and worked initially in research in the Cardio-Respiratory Department at the Royal Victoria Hospital in Montreal, joining McMaster University in 1968. Her research at McMaster involves inhaler characterization and performance, investigations into the behaviour of therapeutic aerosols in patients with asthma and COPD with special interest in the measurement of drug delivery to the lung using 2D Planar and 3D PET imaging. Current work involves investigations of the delivery of vaccine aerosols as well as the function of ciliated epithelial cells in COPD. She was involved in the design and characterization of the Aerochamber™, a holding chamber spacer device for pressurized inhalers used worldwide by patients with respiratory disease. She has published 140 book chapters and peer-reviewed papers in the medical literature and has spoken extensively on pulmonary drug delivery systems and imaging. She currently serves as Chair of the Canadian Standards Association (CSA) Technical Sub-Committee, the group that prepared the national standard for spacers (CAN/CSA Z264.1-02:2002) and other drug delivery devices. She is also Head of the Canadian Delegation to the Canadian Advisory Council for the ISO Technical Committee 84 that developed the standards for aerosol drug delivery devices (ISO 27427, ISO 20072). She is a member of the Health Canada Scientific Advisory Committee for Respiratory and Allergy Therapies (SAC-RAT) and has served on the Board of Directors of the International Society for Aerosols in Medicine (ISAM). Currently, she is a member of the Editorial Boards of the Journal of Aerosols in Medicine Pulmonary Drug Delivery and Pediatric Allergy, Asthma and Immunology. In 2006, she was awarded the AAAR/ISAM Thomas T Mercer Prize and in 2009, the ISAM Career Achievement Award. An ISAM Student Travel Award has been established in her name. She has organized and co-chaired 4 international meetings on drug delivery devices under the DIA umbrella and also for the AARC. In 2009, she arranged a 2-day teaching program for practical laboratory experience in aerosol basics, aerosol measurements and techniques, including applications to research and pharmaceutical laboratory and clinical settings. With contributions from the Aerosol School faculty, the program has been expanded and will be held for the 9th year in 2017.

My primary research training is as a physiologist. My MSc training was in the field of exercise physiology, investigating the factors limiting oxygen uptake during exercise. Following this, I switched to the study of ventilator mechanics for my doctoral studies. My interest at that time was the contribution to ventilation during exercise from the expiratory muscles. After my medical training, I switched my focus to the study of asthma. While I have been involved in several distinct research directions within the study of asthma, my prime interest has always been to better understand the mechanisms of airway hyperresponsiveness in asthmatic patients.

My research activities have included patient based clinical research. This has included looking at the impact of several pharmacological interventions on airway responsiveness, as well as using controlled allergen exposures to alter the degree of airway responsiveness in asthmatic patients. In addition to this, I have developed several mouse models of exposure to allergen. The focus of the animal model work has also been to understand that factors that result in airway hyperresponsiveness in allergen exposed mice. Currently, as well as ongoing interest in the basic mechanisms of airway hyperresponsiveness, I am interested in improved patient education as a means for improving control in asthma.

A major use of my time recently has been the development and running of a course on Research Methodology in Health Sciences. This course is aimed at beginning level graduate students, with the goal of providing greater insight into the processes of designing and running a research study.

During my research training, I held research awards from the National Science and Engineering Research Council as well as from the Canadian Respiratory Society and Medical Research Council of Canada. Since joining the faculty of Health Science at McMaster, I have held the positions of Assistant Professor, Associate Professor and now Professor. I have received funding for my research from the Canadian Thoracic Society, The Medical Research Council, the Canadian Institute of Health Research and from the US based National Institute of Health. I have published over 130 peer reviewed manuscripts relating to my research.

Dr. Roberts has a broad background in the generation and measurement of particles including in the fields of air pollution control, clean room contamination control, pharmaceutical inhaler testing equipment, and biological cell analysis. He is trained in Chemical Engineering and did his thesis work at Cal Tech (Pasadena, CA) with Dr. Sheldon Friedlander, one of the fathers of modern aerosol science. He is co-inventor of the Next Generation Impactor (NGI), the only cascade impactor designed purposely for the testing of metered-dose, dry-powder, and similar inhalable drug products. He has developed practical methods to allow impactor users to determine whether their impactors are suitably within compendial specifications, including the concept of “effective diameter” calculated from optical measurements of impactor nozzles and including the relationship of pressure drop to particle capture efficiency. He has helped develop a series of labor-saving equipment that assists users to recover the drug product from impactors in a manner suitable for quantitative analysis. In his 19 years at MSP Corporation, he grew the inhaler testing equipment and services business into approximately 50% of MSP’s annual revenues and was responsible for strategic marketing of all of MSP’s products. He is now an independent consultant, assisting customers with their most difficult particle sizing measurements and implementing methods of increasing the speed, precision, and accuracy of inhaler testing.

Dr. Roberts is a guest member of the Impactor Sub-group of the European Pharmaceutical Aerosol Group, a member of the American Association of Pharmaceutical Scientists, a contributor to the USP Aerosol Experts committee, on the editorial board of Inhalation (CSC Publishing Inc.), and a regular contributor and reviewer of articles in the Journal of Aerosol Medicine and Aerosol Science and Technology.
