Reference excerpt

Marija Drndic (born November 2, 1971) is the Fay R. and Eugene L. Langberg Professor of Physics at the University of Pennsylvania. She works on two-dimensional materials and novel spectroscopic techniques.

Early life and education Drndic studied physics and mathematics at Harvard University and spent a year at the University of Cambridge in the Semiconductor Physics Group. At Cambridge Drndic worked on quantum transport of coupled gases with Michael Pepper. At Harvard University she was a member of Phi Beta Kappa and graduated summa cum laude. Drndic was awarded a Clare Booth Luce Fellowship, the Harold T. White Prize for Excellence in Teaching and the Robbins Prize from Harvard University. She remained there for her doctoral studies, working with Robert Westervelt on microelectromagnets for cold-atom experiments. She before joining the Massachusetts Institute of Technology as a Pappalardo Fellow. As a postdoctoral researcher Drndic worked on electron transport in cadmium selenide nanocrystals. She worked alongside Marc A. Kastner and Moungi Bawendi on novel spectroscopies.

Research and career In 2003 Drndic joined the University of Pennsylvania. She was awarded an American Chemical Society Petroleum Research Fund Award in 2004, and has since been supported by the National Science Foundation, Alfred P. Sloan Foundation and DARPA. In 2005 Drndic was awarded a Presidential Early Career Award for Scientists and Engineers. Her work considers low-dimensional materials including nanowires, nanocrystals and biomaterials. Drndic uses electron beams to image and shape materials. In particular, Drndic works on two-dimensional nanopores, which are nanoscale size holes that can be used to detect single molecules. They are typically used for biomolecular analysis, but were unable to sequence DNA. Drndic demonstrated it is possible to use light to control the shape of nanopores, indicating it may be possible to fabricate them using light. By removing individual atoms from the nanopores using ion beams, Drndic demonstrated that the nanopores can also be used in water desalination. She has shown that nanopores can be integrated with field-effect transistors to sense nearby ionic and electrical currents. They can also provide information on the physical and chemical properties of biomolecules including DNA and proteins.

Worked examples

Example 1 — a first encounter with Marija Drndic

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

In research: Marija Drndic appears in physics 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 Marija Drndic 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: Marija Drndic is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1971 births, 21st-century women physicists, Alumni of the University of Cambridge, so understanding it makes those chapters shorter.
In everyday life: Look for Marija Drndic 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.
