Reference excerpt

Hedi Mattoussi is a Tunisian-American materials scientist and professor at Florida State University. His research considers colloidal inorganic nanocrystals for biological imaging and sensing. He is a Fellow of the American Physical Society, American Chemical Society and Materials Research Society.

Early life and education Mattoussi studied physics at the University of Tunis El Manar, which he completed with honours in 1982. He completed his doctoral research at the Université Pierre-et-Marie-Curie, where he studied mesomorphic polymers in solution. On completing his PhD, Mattoussi was made a research associate at the Collège de France. He moved to the United States in 1987, first joining University of Massachusetts Amherst, then Carnegie Mellon University.

Research and career In 1992 Mattoussi joined the University of Florida, where he worked as an assistant scientist in the department of physics. Mattoussi joined the United States Naval Research Laboratory in 1997, where he served as principal investigator. There he developed inorganic nanoparticles and studied how they interact with biological systems. Mattoussi joined the faculty at Florida State University as a professor of chemistry, where he leads a group that study the interfaces between inorganic nanocrystals and biological systems. To this end, he designs and synthesises novel nanocrystals based on semiconductors and metallic nanoparticles, creates multifunctional ligands and studies nanoparticle-bioconjugates. He has used quantum dot fluorophore to study the Förster resonance energy transfer process. Mattoussi serves on the advisory board of Physical Chemistry Chemical Physics.

Worked examples

Example 1 — a first encounter with Hedi Mattoussi

Start with the simplest possible case. Write down what Hedi Mattoussi claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Hedi Mattoussi 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 Hedi Mattoussi 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 Hedi Mattoussi

In research: Hedi Mattoussi appears in astronomy 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 Hedi Mattoussi 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: Hedi Mattoussi is common in secondary-school and first-year university syllabi. It links to neighbouring topics American materials scientists, American people of Tunisian descent, Fellows of the American Chemical Society, so understanding it makes those chapters shorter.
In everyday life: Look for Hedi Mattoussi 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.
