Key takeaways

John R. Hetling belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect John R. Hetling to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of John R. Hetling from memory before moving on to harder problems.

Reference excerpt

John R. Hetling is an associate professor at the University of Illinois at Chicago in the Richard and Loan Hill Department of Bioengineering and department of ophthalmology and visual sciences. He is also the director of undergraduate studies for the department of bioengineering and the director of the Neural Engineering Vision Laboratory at UIC, and chief science officer of RetMap, Inc. At UIC, Hetling developed the first undergraduate course track in neural engineering, and in 2008, he and his students authored a widely accepted definition of the field.

Education After graduating from Bates College in 1989 with a degree in biology, Hetling worked for two years in the neuroelectrophysiology laboratory of Patsy Dickinson at Bowdoin College studying rhythmic motor pattern generation. He then began his PhD at UIC in 1991 in the laboratory of David R. Pepperberg, which he completed in 1997. Following his PhD he did a postdoctoral fellowship in the Department of Ophthalmology and Visual Sciences at UIC before being named a visiting assistant professor in the department of bioengineering, also at UIC. Hetling began his tenure track faculty position as an assistant professor at UIC in 1998.

Career Hetling is an expert on the electrophysiology of vision, with accomplishments in retinal prosthesis and electrical stimulation therapy for retinal disease, leading to invited book chapters in leading Neural Engineering textbooks and earning the Excellence in Neural Engineering Award early in his academic career. He has published extensively in the field. His main impact is the development of new diagnostic technologies for degenerative eye diseases, where he pioneered the idea of examining the peripheral retina for early signs of disease. He developed the enabling technology behind multi-electrode electroretinography (meERG), with two issued US patents, both under commercial license. He also developed the enabling technology behind peripheral pattern electroretinography (ppERG), with two international patents pending. Hetling also co-developed the first odor-detection system capable of identifying airborne odors in real time, and has patents pending for developing technologies related to clinical electrophysiology and therapeutic hypothermia.

Family He is the brother of journalist Matt Hongoltz-Hetling.

Worked examples

Example 1 — a first encounter with John R. Hetling

Start with the simplest possible case. Write down what John R. Hetling claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to John R. Hetling before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about John R. Hetling ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of John R. Hetling

In research: John R. Hetling appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses John R. Hetling in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: John R. Hetling is common in secondary-school and first-year university syllabi. It links to neighbouring topics American bioengineers, American ophthalmologists, American science teachers, so understanding it makes those chapters shorter.
In everyday life: Look for John R. Hetling outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
