Medical researching, statistical analysis

Professional study design combined with statistical analysis is a powerful technique that enables a researcher to draw meaningful conclusions from a study in which data are collected through observation, survey or experimentation. I would be glad to use my science research background in your projects. I live in Kazakhstan and ready for business trips, if my skills are needed. Contact me



The success of a medical study however depends to a great extent, on the proper interpretation of the data emanating from such a study.

Dr. Valivach Medical Science Big Data Statistics Analytics

Some of my science research job experience:
 

Semipalatinsk Soviet nuclear test site research
My team investigated human health effects of nuclear tests performed at the Semipalatinsk Nuclear Test Site the main test site of the USSR. We studied archive records on more than 60000 residents of the test site vicinity. 
I also had a three-month training in epidemiology, medical and demographic statistics at the Hiroshima University’s Research Institute for Radiation Biology and Medicine.


 

Official guidelines development
I am a co-author of Guidelines in Epideiological Researches and Evidence Based Medicine ordered by the Kazakhstan State Health Ministry. 


   

Practice as a medical educator
Contracted by USAID I gave a number of lectures on arrangement of scientific researches in medicine and demography as well as ethics of clinical research in several countries. I also an author of more than 30 books and articles. 


 

Development of medical software algorithms
I supervised and participated in two medical expert systems development. The systems were designed for diagnosis of chronic diseases. Algorithms of diagnoses were described using logical formulas of Boolean algebra and special language developed for these systems. This specialized language allows satisfactory description of disease syndromes using patient parameters, numerical data of tests, and description of symptoms using textual and graphical data. As criteria descriptions of diseases eMedicine, Merck manual and GPnotebook sources were used. The expert systems contain more than 2000 symptoms and diagnostic algorithms of more than 1500 diseases.


 

Investigation of general and reproductive health in adolescent girls
The study project which then was granted by McArthurs’ Foundation was developed by me. I aslo directed and controlled all project works, performed statistical analysis and wrote the final report. One of the goals of this study was searching for possible mercury health impact  in the residents of the city of Pavlodar situated near the mercury contaminated area.
