Biostatistics is the application of statistical techniques to scientific research in health-related fields, including medicine, biology, and public health, and the development of new tools to study these areas. Since the beginning of the twentieth century, the field of biostatistics has become an indispensable tool in improving health and reducing illness.
What do Biostatisticians do?
Biostatisticians play essential roles in designing studies, analyzing data and creating methods to attack research problems as diverse as:
-the determination of major risk factors for heart disease, lung disease and cancer
-the testing of new drugs to combat AIDS
-the evaluation of potential environmental factors harmful to human health, such as tobacco smoke, asbestos or pollutants.
What are the career prospects for Biostatistics PSM graduates?
Job prospects for biostatistics graduates are excellent, with career opportunities in university research facilities and pharmaceutical and medical device companies.

What is Survival Analysis?
Survival analysis concerns the statistical modelling of time-to-outcome data, i.e. data where the variable of primary interest is the time interval between some specified origin and the event of interest occurring. The event of interest is usually referred to as the outcome or endpoint (other terms include terminating or target event, or failure). Survival data may also be referred to as time-to-event data, lifetime data, failure time data, reliability data, duration data or event history data. It arises commonly in applications in Medicine, Social Sciences and Engineering.
What is Clinical Trials?
A clinical trial is a research study to answer specific questions about vaccines or new therapies or new ways of using known treatments. Clinical trials (also called medical research and research studies) are used to determine whether new drugs or treatments are both safe and effective. Carefully conducted clinical trials are the fastest and safest way to find treatments that work.
