### Suggested Tracks:

## Statistics Track

The discipline of biostatistics applies statistical theory and methodology to the biological sciences. Based in the mathematical sciences, biostatistics is concerned with developing an empirical basis for understanding biological mechanisms and for medical and health policy decisions that profoundly affect our lives. Examples include:

- Designing and analyzing studies to determine if new drugs and medical devices are safe and effective (at a pharmaceutical company, medical research center, or the Food and Drug Administration)
- Designing studies for and analyzing data from agricultural experiments to increase productivity and yield (at an agricultural college or agribusiness corporation)
- The search for improved medical treatments rests on careful experiments that compare promising new treatments with the current state of the art. Statisticians work with medical teams to design the experiments and to analyze the complex data they produce.
- Studies of the environment require data on the abundance and location of plants and animals, on the spread of pollution form its sources, and on the possible effects of changes in human activities. The data are often incomplete or uncertain, but statisticians can help uncover their meaning.

ST491 (Statistical Special Topics - when applicable)## Differential Equations/Modeling Track

Mathematical models are important tools in basic scientific research in many areas of biology, including physiology, ecology, evolution, toxicology, immunology, natural resource management, and conservation biology. The result obtained from analysis and simulation of system models are used to test and extend biological theory, and to suggest new hypotheses or experiments. Models are also widely used to synthesize available information and provide quantitative answers to practical questions. What measures can be used to reverse the decline in sea turtle populations, and how soon can we tell if they are working? How can laboratory experiments on chemical carcinogenicity be scaled up to set safe exposure limits on humans? For questions like these, where it is desirable to predict the outcome accurately before action is taken, quantitative modeling is essential. This track emphasizes the use of mathematical methods such as differential equations, dynamical systems, and other analytic techniques.

Discrete mathematics and algorithmics play a fundamental role in modern computational and molecular biology. Problems concerning areas such as genetic mappings, DNA structure and molecular evolution often involve interesting combinatorial and algorithmic models. For example, comparison of extensive molecular sequences and extraction of information from them is a central problem in modern computational biology. This track emphasizes the study of algorithms, and combinatorial and graph theoretic structures.
