More and more researchers are combining the fields of mathematics and biology. The goal is to explain complex biological phenomena using mathematical models. Recently, there has been a rapid increase in research in mathematical biology. Specific areas include population dynamics, cell and molecular biology, and physiology.
Mathematical models used in biology have large-scale impact. For example, models explaining the spread of certain viruses have been used to make health policy decisions. Mathematical modelling of the heart has been used in developing certain treatments for ventrical defribilation and arterial disease. Other applications include cancer modelling, mechanics of biological tissues, and more.
