Conduct qualitative and quantitative chemical analyses or experiments in laboratories for quality or process control or to develop new products or knowledge.

Research and study the inheritance of traits at the molecular, organism or population level. They evaluate or treat patients with genetic disorders.

Conduct research using bioinformatics theory and methods in areas such as pharmaceuticals, medical technology, biotechnology, computational biology, proteomics, computer information science, biology and medical informatics. They design databases and develop algorithms for processing and analyzing genomic information, or other biological information.

Study the origins, behavior, diseases, genetics, and life processes of animals and wildlife. They specialize in wildlife research and management. They collect and analyze biological data to determine the environmental effects of present and potential use of land and water habitats.

Investigate the growth, structure, development, and other characteristics of microscopic organisms, such as bacteria, algae, or fungi. Includes medical microbiologists who study the relationship between organisms and disease or the effects of antibiotics on microorganisms.

Use chemistry, microbiology, engineering and science to study the processing and deterioration of foods. They analyze food content to determine levels of vitamins, fat, sugar, and protein. They discover new food sources and ways to make processed foods safe, palatable, and healthful. They determine best ways to process, package, preserve, store and distribute food.

Calculate mapmaking information from field notes, and draw and verify accuracy of topographical maps.

Perform site specific engineering analysis or evaluation of energy efficiency and solar projects involving residential, commercial, or industrial customers. They design solar domestic hot water and space heating systems for new and existing structures, applying knowledge of structural energy requirements, local climates, solar technology, and thermodynamics.

Design, develop, or supervise the production of materials, devices, or systems of unique molecular or macromolecular composition, applying principles of nanoscale physics and electrical, chemical, or biological engineering.

Design, develop, or evaluate energy related projects or programs to reduce energy costs or improve energy efficiency during the designing, building, or remodeling stages of construction. They specialize in electrical systems; heating, ventilation, and air conditioning (hvac) systems; green buildings; lighting; air quality; or energy procurement.
