Research Interests and Expertise

Dr. Gajic-Veljanoski’s research involves applications of the methods of clinical epidemiology, evidence synthesis, decision analysis and economic evaluation. Her doctoral research included quantitative analyses of uncertainty of the efficacy of vitamin K for fracture prevention using the methods of Bayesian univariate and bivariate meta-analyses and economic evaluation. It resulted in a fracture incidence-based Markov microsimulation model, used to analyze the incremental cost-effectiveness of lifetime supplementation with vitamin K, vitamin D and calcium for the prevention of fractures. Dr. Gajic-Veljanoski’s current interest focuses on the evaluation of benefits of the Bayesian method for meta-analytic modelling of single and multiple health outcomes and the assessment of validity of Bayesian predictions. Her future research will focus on chronic diseases and the use of decision analysis, disease modelling and economic evaluation for making relevant and transparent health policy decisions.
