Hanah Margalit

Hanah Margalit is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Hanah Margalit rather than just read about it. In short: Hanah Margalit (Hebrew: חנה מרגלית) is a professor in the faculty of medicine at the Hebrew University of Jerusalem. Her research combines bioinformatics, computational biology and systems biology, specifically in the fields of gene regulation in bacteria and eukaryotes.

Key takeaways

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

Reference excerpt

Hanah Margalit (Hebrew: חנה מרגלית) is a professor in the faculty of medicine at the Hebrew University of Jerusalem. Her research combines bioinformatics, computational biology and systems biology, specifically in the fields of gene regulation in bacteria and eukaryotes.

Education Margalit earned her BSc degree (in mathematics and biology, 1974) and MSc degree (in genetics, with distinction, 1977) from the Hebrew University of Jerusalem. In 1985, she completed her PhD in computational molecular biology, under the supervision of Norman Grover, the Hebrew University of Jerusalem.

Career and research Margalit completed postdoctoral research at the National Institutes of Health (NIH) in the laboratory of mathematical biology under the supervision of Charles DeLisi, where she developed the first computational algorithm to predict antigenic peptides recognized by immune cells. In 1989, she returned to Israel and established her independent research group at the Faculty of Medicine, the Hebrew University of Jerusalem. Her early research included development of computational algorithms for predicting binding of antigenic peptides to MHC molecules, computational models of protein-DNA binding preferences, also in collaboration with Nir Friedman, identification of domain pairs as the building blocks of protein-protein interaction networks, analysis of the integrated network of protein-protein and protein-DNA interactions (in collaboration with Uri Alon), as well as computational models for predicting small regulatory RNA molecules in bacteria, which were verified experimentally in collaboration with Shoshy Altuvia and Gerhart Wagner. More recently, Margalit's lab studied the dynamics of regulation by small RNAs (in collaboration with Ofer Biham), and computationally predicted that there are viral microRNA molecules that repress the human immune system, a mechanism that was experimentally validated in collaboration with Ofer Mandelboim. Since 2012, Margalit has combined experimental and computational research for studying small RNA-target interactions in bacteria. Margalit was one of pioneering researchers of Bioinformatics and Computational Biology in Israel and worldwide. At the Hebrew University she co-founded the "Computer Science and Life Sciences" program in Bioinformatics and Computational Biology (in 1999) and the graduate "Genomics and Bioinformatics" program (in 2000). In 2002 she was elected as the first president of the Israeli Society of Bioinformatics and Computational Biology (2002-2004). Margalit has mentored over 50 graduate students, many of them holding faculty positions in bioinformatics in Israel and abroad.

Awards and honors In 2008 she was awarded the Michael Landau prize in Systems Biology. In 2018, Margalit was elected a fellow of the International Society for Computational Biology (ISCB) for outstanding contributions to the fields of computational biology and bioinformatics. In 2020, Prof. Margalit was awarded the Rothschild Prize in Computational Biology.

Personal life Margalit is married to Avi and a mother of three children.

Worked examples

Example 1 — a first encounter with Hanah Margalit

Start with the simplest possible case. Write down what Hanah Margalit 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 Hanah Margalit 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 Hanah Margalit 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 Hanah Margalit

In research: Hanah Margalit 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 Hanah Margalit 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: Hanah Margalit is common in secondary-school and first-year university syllabi. It links to neighbouring topics Academic staff of the Hebrew University of Jerusalem, Israeli bioinformaticians, Living people, so understanding it makes those chapters shorter.
In everyday life: Look for Hanah Margalit 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.
