From the field
The same lessons come up again and again from people actually doing the job:
People hear 'biotechnologist' and think pure biology. I engineer living systems — cells, genes, microbes — to make real things: medicines, materials, sustainable products. It's biology turned into technology, and it's at the frontier of science.
