A biophysicist is a scientist who studies the physical principles underlying biological processes. They use techniques from physics, chemistry, and biology to understand how living organisms function at a molecular and cellular level. This can include research on proteins, DNA, and cellular structures, helping to explain how these components interact and contribute to life. Biophysicists often work in laboratories, conducting experiments and analyzing data to uncover the mechanisms of biological systems. Their work can lead to advancements in fields such as medicine, biotechnology, and environmental science, making significant contributions to our understanding of life and health.
