What does bioengineer mean?
A bioengineer is a professional who brings engineering methods to bear on living systems and biological problems. Rather than simply studying life, bioengineers design and build things that work with it: artificial joints and organs, lab-grown tissue, medical sensors, genetically modified crops, and processes for manufacturing drugs. The word combines the Greek-derived prefix 'bio-', meaning life, with 'engineer', and it emerged alongside the modern field of bioengineering in the mid-twentieth century. Most commonly used as a noun for a person trained in this discipline, it can also function as a verb meaning to alter an organism through genetic or biological engineering. The term carries connotations of cutting-edge science and innovation, appearing frequently in coverage of regenerative medicine, synthetic biology, and biotechnology. Related terms include biomedical engineer and biotechnologist, with which it overlaps considerably in everyday use.
A specialist who applies engineering principles to biological or medical problems, designing devices, tissues, or systems that interact with living organisms.
"The bioengineer spent years perfecting a retinal implant that restores partial vision."
Often used interchangeably with 'biomedical engineer', though some reserve 'bioengineer' for non-medical applications such as agriculture and industry.
To modify or create an organism or biological material using genetic or bioengineering techniques.
"Researchers bioengineered a strain of rice that produces vitamin A."
Standard plural; used both for individuals in the profession collectively and for multiple practitioners in a team or organization.
"A team of bioengineers collaborated with surgeons to develop the new cardiac patch."
Bioengineers have grown human ear cartilage on the backs of mice — a real experiment that made 'spare parts' for the body feel less like science fiction.

Etymology of bioengineer
The word bioengineer is formed from the combining form 'bio-', from Greek 'bios' meaning 'life', joined to 'engineer', which traces back through French 'ingénieur' to Latin 'ingenium', meaning natural ability or cleverness. The compound arose in English in the twentieth century as bioengineering developed into a distinct discipline after World War II. It shares its 'bio-' element with words like biology and biography, and its '-engineer' element with civil, chemical, and mechanical engineer.

How bioengineer is actually used
The term is neutral and professional in register. It is broader than 'biomedical engineer' in some usage, covering agricultural and industrial applications of biology as well as medical ones, though in everyday speech the two are often used interchangeably. As a verb ('to bioengineer' an organism), it appears mainly in scientific and journalistic writing about genetic modification.
Easily confused with bioengineer
A biologist studies living organisms to understand them, while a bioengineer applies engineering methods to modify or build with biological systems.
A biochemist studies chemical processes within living things, whereas a bioengineer designs practical devices, materials, or systems using engineering principles.
