biologista

Biologista is a professional who studies living organisms and their interactions with each other and the environment. The term is used in several languages to denote a scientist who specializes in biology, the natural science concerned with life and living systems. Biologists investigate the structure, function, growth, origin, evolution, and distribution of organisms, using methods from chemistry, physics, mathematics, and informatics to understand life processes.

Education and work often begin with a university degree in biology or a related field. A bachelor’s degree enables entry-level research or teaching positions, but many roles require advanced training, such as a master's or doctoral degree. Practical experience in the laboratory and fieldwork is essential, as is competence in data analysis, experimental design, and scientific communication. Professional development may include training in biosafety, ethics, and regulatory compliance.

Biologists work across diverse sectors. In academia and research institutes, they design and conduct experiments, publish results, and teach students. In healthcare and public health, they study pathogens, immune responses, and genetic diseases. In agriculture and environmental science, they address crop improvement, pest control, conservation, and ecosystem monitoring. The biotechnology and pharmaceutical industries apply biological knowledge to develop products and treatments.

Subfields of biology commonly pursued by biologists include botany, zoology, microbiology, genetics, ecology, physiology, anatomy, marine biology, and bioinformatics. The discipline emphasizes evidence-based reasoning, careful observation, and reproducibility, and it operates within ethical and regulatory frameworks to protect organisms, ecosystems, and human health.
