  • Biography

    In 1997, Dr. Elkum earned a Ph.D. degree in statistics from Queen’s University Canada. More than 30 years of biostatistics and related health experience in internationally recognized institutions: National Cancer Institute of Canada Clinical Trials Group Queen’s University (NCIC, CTG), Canada; Health Canada: Laboratory Center of Disease Control (LCDC), Ottawa, Canada; Pharma Medica Research Inc. (PMRI), Mississauga, Canada; King Faisal Specialist Hospital & Research Center, Riyadh, KSA; Dasman Diabetes Institute (DDI), Kuwait; and Sidra Medicine, Qatar. His areas of expertise included: epidemiology, biostatistics, clinical trials, medical writing, and bioequivalence studies. 

    Dr. Elkum is a research methodologist with research interests in the development and application of statistical methods in health research. His research interests cover a wide spectrum of areas including design and analysis of RCTs; generalized linear/nonlinear mixed effects models; failure time data; statistical methods in epidemiology and cancer; Bayesian and non-Bayesian inference and statistical consulting.

    He has collaborated with researchers in cardiology, internal medicine, diabetes, obesity, urology, oncology, pathology and health technology assessment. He has provided statistical leadership in studies in various areas of population health research, clinical research and health services and outcomes research.
  • Services and Approach

    Resources, time and money will be devoted to the development of analytic epidemiological and statistical models to reduce uncertainty and provide error free methodologies to produce indices about population health that can aid in medical decision making.

    The Biostatistics and Epidemiology Core will be focusing on the following subspecialties: 
    • Statistical Genetics & Genetic Epidemiology: Genetic Association Studies, Genetic Data Tests, Multiple Comparison Procedures, Methods for Unobservable Phase and population genetics,

    • Statistical Machine Learning: Linear Regression, Classification, Resampling Methods, Linear Model Selection and Regularization, Polynomial Regression, Smoothing Splines, Decision Trees, Bagging, Random Forests, Boosting, Support Vector Machines, Principal Components Analysis, Clustering Methods, deep and Multitask learning,

    • Clinical Biostatistics: design and analysis of RCTs; generalized linear/nonlinear mixed effects models; failure time data; Bayesian and non-Bayesian inference. Traditional primary safety/efficacy analyses for phase I-IV studies. Compartmental PK modelling, statistical analyses including bioequivalence and bioavailability.
