BiologyIn 1963 there were two tracks that an electrical engineering student at Lehigh University could choose from — electronics or power. Electronics was about solid state devices such as transistors. (The Intel 4-bit 4004, was not to come until 1971). The “power” track was mostly about electric motors and power generation. There was no computer science program, but the university had recently acquired a GE 225 which occupied a good part of the basement floor of Packard Laboratory. Nearly every department at Lehigh began to include computer programming as part of their curricula. Some departments evolved toward strong computer orientation more rapidly than others but eventually computer science and computer engineering became formal programs of their own.

Fast forward forty years and you can see a very similar evolution occurring with regard to bioengineering. Initially “bio” was a special interest area that spread roots from the biology department into various engineering disciplines. Bioengineering has already become a structured curriculum for students interested in the intersection between engineering and biological sciences. The bioengineering faculty is drawn from several departments in the college of engineering and applied science and the college of arts and sciences. Bioengineering combines engineering principles with the life sciences. There are three tracks available to students. Biopharmaceutical engineering encompasses biochemistry and chemical engineering. Bioelectronics/biophotonics focuses on applications of electrical engineering and physics in bioengineering such as signal processing, biosensors, and biochips. Cell and tissue engineering straddles the fields of molecular and cell biology, materials science, mechanical and electrical engineering and encompasses biomaterials and biomechanics. Studies range from cells and tissue to organs and systems. Sound a bit different than transistors and electric motors?

The exciting part of all this is that engineering students with “bio” in their pedigree have much broader career potential including healthcare, biomedical, pharmaceutical, biomaterials, and medicine. Even more exciting is the possibility for those of us who started out back in the days of the transistors and motors and have aging bodies that some day will benefit from bioengineered “components”. The implantable pacemaker was just the beginning. Bioengineering graduates will be developing pacemakers for the brain, cochlear implants for hearing deficiencies, artificial cartilage for our knees, devices to enable the blind to see, and cures for today’s incurable diseases. At some point a nanotechnology “cocktail” will bring nanobots to our internal systems to replace faulty cells with newly engineered ones. Just like computers have become ubiquitous, it is clear that bioeverything is on the horizon. Bioethics will become a larger concern but it is clear that the trend toward The Singularity is underway.
