Biostatisticians research statistical theories and advise on their practical applications. They develop and apply mathematical or statistical techniques to solve problems.
In general, biostatisticians:
- Use advanced statistical software to apply the best modelling to analyze specific data
- Create standard scripts and macros to improve the efficiency of statistical programs and outputs
- Perform high-level processing, mining, and visualization of data
- Maintain documentation, storage, and master archive lists of data
- Work with senior scientists and research staff to apply for grants, co-author journal articles, and prepare academic presentations
- Write or supervise the writing of the statistical sections of study reports or publications
Biostatisticians work with researchers to design and analyze studies and clinical trials. They work in areas such as:
- Epidemiology
- Health services research
- Nutrition
- Environmental health
- Health-care policy and management
They use their expertise to help researchers:
- Define hypotheses
- Develop analytical plans
- Set parameters for data gathering
- Ensure project specifications meet the criteria in the analytical plan
- Sample, collect, and clean data
- Raise issues with data analysis
- Synthesize findings for reporting
In public health, biostatisticians:
- Assess the origins or causes of diseases and injuries
- Evaluate the effectiveness of intervention programs or policies
- Monitor and detect trends in population health
In universities, biostatisticians:
- Conduct health science research
- Teach and train undergraduate and graduate students
- Collaborate with researchers in diverse fields
In biomedical research, biostatisticians apply methods from statistical, population, or quantitative genetics, or statistical genomics. They:
- Study molecular markers for traits in human populations
- Find gene alleles, or variants, that can cause or influence predisposition to genetic diseases
- Study the genetic basis for human, plant, or animal traits that are influenced by more than one gene
- Identify genes whose quantity changes a lot between different states or stages of disease
In the commercial sector, biostatisticians work with large datasets from clinical trials, patient support programs, or government data sources. They:
- Try to understand the burden of disease
- Explore the need for new health technologies such as drugs, medical devices, and diagnostics
- Provide oversight and guidance to team members and trial sponsors on multiple-trial programs, complex trials, and submission projects
