New Faculty

Dr. Deborah E. de Lange

Faculty of Business Administration

Dr. Deborah E. de Lange joined the Faculty of Business Administration in July 2011 as an assistant professor of international business. Dr. de Lange has a bachelor in applied science and engineering (electrical) from the University of Toronto, a master of business administration in science and technology (honours) from Queen's University and a PhD in strategic management from the Joseph L. Rotman School of Management, University of Toronto.

Dr. de Lange is also a Certified Management Accountant (CMA).

Prior to joining Memorial, she was an assistant professor of strategy and international business in Boston, MA. She taught globalization and sustainable strategy to honours students as a capstone course.

Prior to entering academia she worked for over 10 years in various engineering and managerial capacities, including strategy consulting. She has broad experience in areas such as energy, electronics manufacturing, banking and finance, distribution logistics, retail, and pharmaceutical diagnostics.

After Dr. de Lange obtained her PhD at the University of Toronto she published her PhD dissertation as a book entitled Power and Influence: The Embeddedness of Nations.

She has since written two more books The Research Companion to Green International Management Studies and Cliques and Capitalism: A Modern Networked Theory of the Firm. Other research interests include international business and organizations, international trade and foreign direct investment, international relations, corporate governance, strategy and organizations, sustainability in international business, organizational theory – embeddedness and network analysis.


 

Dr. Stephen Raab

Faculty of Medicine

Dr. Stephen Raab has joined the Faculty of Medicine as professor of laboratory medicine, also serving as clinical chief of laboratory medicine with Eastern Health. He is also an adjunct professor of pathology with the University of Washington.

Dr. Raab comes to Memorial from Denver, Colorado where he worked with the Colorado Health Outcomes Program. He served as the director of anatomic pathology with the Department of Pathology at the University of Colorado from 2008-2010. He has also worked at the University of Pittsburgh, the University of Iowa Hospitals and Clinics and as an advisor to the Pathology Department at the Ho Chi Minh City Cancer Hospital in Viet Nam.

With over 190 refereed articles, Dr. Raab has an impressive publication record. His current research interests include pathology outcomes, surgical pathology, cytology, fine needle aspiration biopsy, health services and international cytology. Among his current projects he is looking at pathology errors and effects of error on patient outcomes, patient and clinical preference of pathology testing, quality assistance guidelines in anatomic pathology, measurement of bias in pathologic diagnoses, and the effect of immunohistochemistry on patient outcomes.

Dr. Raab earned his MD in 1988 at State University of New York Health Science Center at Syracuse, New York. From 1986-1987 he held a Dana Fellowship at the University of Pennsylvania in epidemiology. His postgraduate work was at Barnes Hospital, Washington University Medical Center in St. Louis; Pitt County Memorial Hospital, East Carolina University School of Medicine in Greenville; and the Department of Health Research and Policy at Stanford University School of Medicine in Stanford, California.



Dr. Guangju Zhai

Faculty of Medicine

Dr. Guangju Zhai joined Memorial's Faculty of Medicine in May 2011 as an associate professor in population and statistical genetics.

He received his medical training in China and practiced for nine years as a family physician before obtaining his M.Sc. in genetic epidemiology at Erasmus University Rotterdam, The Netherlands, and a PhD in epidemiology at Menzies Research Institute, University of Tasmania, Australia. Before joining Memorial, he was a senior genetic epidemiologist at the Department of Twin Research and Genetic Epidemiology, King's College London, U.K.

Dr. Zhai's research focuses on identifying genetic factors for aging and age-related diseases, particularly musculoskeletal disorders. Using twin modelling and family-based study design, he has revealed a significant genetic component in both the development and progression of osteoarthritis and in osteoporosis. Over the last four years, he has been heavily involved in genome-wide association studies of complex traits. He is a member of several international consortia including the Cohorts for Heart and Aging Research in Genomic Epidemiology; the Reproductive Traits Genetics Consortium, Arthritis Research U.K. Osteoarthritis Genetics; Translational Research in Europe Applied Technologies for OsteoArthritis; and SpiroMeta, an international consortium of 96 scientists from 63 centres in Europe and Australia.

Dr. Zhai is the lead author of a recently published paper in PLoS Genetics that identified eight common genetic variants are associated with serum levels of dehydroepiandrosterone sulphate (DHEAS). DHEAS declines with increasing age, which has led to speculation that a relative DHEAS deficiency may contribute to the development of common age-related diseases or diminished longevity.

Using the unique resource of Newfoundland population, Dr. Zhai is going to set up a genetic study of osteoarthritis to identify genetic and epigenetic factors for development and progression of osteoarthritis in Newfoundland and Labrador. He will also be involved in genetic studies in other diseases such as colon cancer in collaboration with other faculty members.
