“A chemist is a scientist who studies atoms and molecules - the 'building blocks' of our world - and applies that knowledge to design, synthesise, and test new materials that work better, are safer, stronger or more sustainable than existing ones.” Explains Dr. Hung.
There are many types of chemists, and chemists can work in various scientific fields, such as pharmaceuticals, materials science, environmental science, and energy materials. They may also be involved in quality control, research and development, teaching, or policy development.
“Although many chemistry jobs involve lab work, not all chemists work in a lab. Some spend most of their time using supercomputers and AI models to study molecules at the atomic level to design new molecules that are more effective medicines, more efficient energy materials, or have better tensile properties.” Says Dr. Hung.
As a result, a chemist’s role depends heavily on their specific field and role. Generally, however, a few of the tasks common to most chemists’ roles will include:
- Performing experiments - Designing and conducting experiments to synthesise or investigate the properties of substances. This can involve designing or improving processes for faster or cleaner reactions. Computational chemists can use simulations and models to predict reactions and design new materials and more effective, safer therapeutics, helping experimental chemists develop new products much faster.
- Product development - Designing and optimising formulations and chemical compositions for products, including pharmaceuticals, cosmetics, food and, materials for batteries, buildings, aircraft, and many more.
- Quality control - Chemists test products to meet standards and safety regulations using methods like chromatography and nuclear magnetic resonance to ensure correct and pure products.
- Education and training - You may formally teach at schools or universities, write documentation for new syntheses or instrumental procedures that you’ve developed for other users, or mentor and train colleagues.
