Biological engineers apply engineering, scientific and mathematic principles to biological systems.
Biological engineers use mathematical, scientific and engineering principles and methods to improve the conditions of human beings and living organisms. Unlike biomedical engineering, which relates specifically to the medical field, biological engineers include professionals who specialize in agricultural and environmental engineering. Although a large portion of biological engineers are hired by health care and government agencies, some professionals also work for universities, consulting firms and nonprofit organizations.
Types
Under the field of biological engineering, professionals apply engineering technology to humans, animals and plants. A biomedical engineer develops prosthetic limbs for amputees, surgical instruments, and medical information systems and devices. In agriculture, biological engineers develop machines, equipment and structures used to cultivate crops and conserve soil. Other tasks that fall under agricultural engineers include researching and developing methods for managing water supplies and storing agricultural products. Environmental engineers use biology and chemistry to come up with solutions to reduce pollution, improve recycling programs and effectively dispose of waste. Biological engineers often work for governmental agencies dealing with public health and climate change issues.
Education
Similar to other engineering professionals, entry-level biological engineering jobs require at least a bachelor's degree in engineering, as well as a concentration in mechanical or electronics engineering. Biological engineering programs offer specialty tracks in areas including agriculture and the environment. Students can also concentrate in bioprocess engineering, which is the development of biological materials into systems, instruments and technologies that can be used by humans. Biological engineering students take classes in the sciences, social science, math, agricultural engineering, agricultural machinery, and environmental safety and health. University and college professors, government employees and corporate executives often pursue a graduate degree to advance their skills and broaden their knowledge within the engineering field, reports the U.S. Bureau of Labor Statistics.
Potential
Significant growth is expected for careers in biological engineering, according to the BLS. Between 2008 and 2018, biomedical engineering jobs are expected to grow by 72 percent due to the growing demand for advanced technologies in health care. Employment for agricultural engineers is expected to increase by 12 percent as a result of population growth. Additionally, more efficient and environmentally friendly methods for harvesting crops will be needed to feed expanding towns and cities. Environmental engineering jobs should grow by 31 percent during the 2008 to 2018 decade. The BLS attributes this to rising demand for expertise in environmental legislation and the need for organizations to comply with laws.
Salary
Average annual wages for agricultural engineers was $74,640, according to a May 2009 BLS report. For biomedical engineers, the average annual salary for professionals in the U.S. was $82,550. Environmental engineers earned an average salary of $80,750 per year during the same time period.
