Principal Investigator: Dr. Reinhard Vehring
Dr. Vehring is a Professor in the Mechanical Engineering Department at the University of Alberta and holds the George Ford Chair in Materials Engineering. He graduated with a diploma in Mechanical Engineering from the Gerhard Merkator University in Duisburg, Germany, and received a doctorate from the University of Bochum in the field of molecular spectroscopy on microparticles. Dr. Vehring has held positions in academia and industry advancing aerosol science and particle technology for more than 26 years. Before returning to academia, he worked on pulmonary delivery of peptides, proteins, and small molecules at Nektar Therapeutics and was part of the team developing Exubera, the first inhalable insulin. Subsequently, he developed solid dosage forms for virus vaccines, monoclonal antibodies, and oncology therapeutics at Medimmune, and supported FluMist, the first nasally administered live attenuated influenza vaccine. Dr. Vehring was the lead inventor for the cosuspension formulation technology which is used by Pearl Therapeutics to develop metered dose inhaler based therapeutics for respiratory diseases. At the University of Alberta, Dr. Vehring directs the Particle Engineering facility focusing on advanced micro and nanoparticle design and analysis.
PLEASE NOTE: Dr. Vehring is not accepting any new graduate students.

Senior Research Scientist: Hui Wang
Hui obtained his BSc in Materials Science and Engineering from Southeast University in Nanjing, China. During his MSc and PhD studies with the Particle Engineering Group at the University of Alberta, he focused on designing and applying advanced characterization techniques, including cascade impaction, Raman spectroscopy, and shadowgraphic imaging, for the testing and optimization of inhalation formulations for pressurized metered dose inhalers (pMDIs) and dry powder inhalers (DPIs). He has rich experience in design, production, testing, and pulmonary delivery of medicinal microparticles. He is currently a research scientist to the group, working on various projects related to respiratory drug delivery. His research interests include inhalation formulation development, particle engineering and spray drying.
