Slide background
Department of Biostatistics and Medical Informatics

Department of Biostatistics and Medical Informatics

       Our department was established in 2000. There are 5 faculty members (2 professors, 2 associate professors, 1 assistant professor, 1 lecturer, and 1 research assistant) serving at the Biostatistics and Medical Informatics Department. Graduate programs were established dependent on MEU Health Science Institute. Master and doctorate programs have been accepted students since 2000 and 2004, respectively. 

        Faculty members of the department maintain their researches and develop undergraduate and graduate education programs. In addition, we are developing new methodology projects in order to increase our international competitiveness.

        Computer Laboratory with a capacity of 48 computers is using for applied undergraduate and graduate courses of Biostatistics. In addition, biostatistical consultancy is provided for scientific researches in the field of science and health sciences. The number of 250 theses and scientific researches are consulted annually. We contribute to the acceptability of studies in international journals with statistical eligibility. In addition, we draw attention to the importance of theoretical and applied statistics education in our university and the necessity of statistical eligibility to increase the international competitiveness of scientific researches.

        Our experiences have shown that the statistical terminology using from the plan of the study to the report of the results of scientific research makes a significant contribution to the power of the study. In our department, personalized medicine researches are in progress and decision support systems and interfaces are developed within the scope of these researches.

        Since its establishment, 7 doctorate and 10 master's students have completed their education in our department. There are still 6 doctorate and 5 master's students in education. There are still 6 doctorate and 5 master's students in education. Moreover, there are students who have been awarded a scholarship (100/2000) by the Council of Higher Education and have educated in countries such as England and Sweden with the ERASMUS program.
