Reference excerpt

Paola Picotti (born 1977) is an Italian biochemist who is Professor for Molecular Systems Biology at ETH Zürich. She is Deputy Head of the Institute for Molecular Systems Biology. Her research investigates how the conformational changes of proteins impact molecular networks with cells. She received numerous awarded awards, among which the 2019 EMBO Gold Medal.

Early life and education Picotti grew up in Udine. Her mother was a mathematics teacher and her father worked in an electronics company. Picotti studied medicinal chemistry at the University of Padua, and graduated in 2001. She then moved into biotechnology, working alongside Angelo Fontana for her doctoral research. She joined the laboratory of Ruedi Aebersold as a postdoctoral fellow in the Institute for Molecular Systems Biology at ETH Zürich, where she developed approaches for the targeted analysis of proteins based on mass spectrometry. She was appointed a scientific advisor at Aebersold's spin-out company Biognosys.

Research and career In 2011, Picotti was appointed to the faculty at ETH Zürich, first as an assistant professor at the Institute of Biochemistry and subsequently as an associate and full professor at the Institute of Molecular Systems Biology. She works in the field of mass spectrometry-based proteomics, the large-scale analysis of thousands of proteins from cells and tissues. Whilst proteomics offers the potential for wide-reaching analysis, detail on the structures or shapes of proteins is lost in the process. Picotti developed an approach that solves this problem, since it enables the analysis of the structures of thousands of proteins simultaneously. It combines limited proteolysis and mass spectrometry (so-called "LiP-MS" method), to generate a proteolytic pattern (akin to a barcode) that reports on the structure of every measurable protein in a sample. Comparison of structural barcodes from different biological specimens (e.g. samples from healthy individuals and from individuals with a disease) detects which proteins have altered structures in those specimens. Picotti has shown that this technique can be used to identify a new class of candidate biomarkers of disease (structural biomarkers), unravel basic principles of thermosensitivity of proteins and provide a new and often more sensitive way to detect altered biological processes. Also, since binding of a small molecule locally affects the structure of a protein, the approach can be used to identify targets of small molecules and drugs, binding mechanisms and binding sites, thus rendering LiP-MS a valuable tool in drug development. Picotti uses LiP-MS to study protein aggregation in neurodegenerative disease, with a focus on Parkinson’s disease.

Worked examples

Example 1 — a first encounter with Paola Picotti

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

In research: Paola Picotti appears in biology 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 Paola Picotti 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: Paola Picotti is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1977 births, Academic staff of ETH Zurich, Italian molecular biologists, so understanding it makes those chapters shorter.
In everyday life: Look for Paola Picotti 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.
