She is a professor of Vascular Disease in the Department of Biological Regulation at the Weizman Institute of science, Rehovot, Israel.

Key takeaways

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

Reference excerpt

Karina Yaniv (Hebrew: קרינה יניב) is an Israeli scientist who is best known for her contributions to the field of vascular development. She is a professor of Vascular Disease in the Department of Biological Regulation at the Weizman Institute of science, Rehovot, Israel. She has three kids: Yotam Yaniv, Nitay Yaniv, and Eylon Yaniv, and since 2023 is married to another Weizmann Institute of Science biologist, Eldad Tzahor.

Research Yaniv investigates the mechanisms that regulate blood and lymphatic vessel formation during embryonic development and in disease. She utilizes zebrafish embryos to study the mechanisms controlling the lineage specification of lymphatic endothelial cells and the development of lymphatic vessels. A recent achievement was the discovery of a new niche of specialized progenitors which gives rise to the lymphatic system. They identified the first "lymphatic-inducing" signal, capable of inducing lymphatic differentiation of human embryonic stem cells. Her laboratory generated for the first time human lymphatic endothelial cells in culture, which opens the way for other laboratories to understand the basic determinants and behavioral properties of these cells. Research in Yaniv's laboratory also focuses on lymphatic vessels in the heart: how do they form and what is their possible role in heart diseases. Other projects focus on the mechanisms that control the formation of lymphatic vessels induced by tumors, since the lymphatic system is the key route for dissemination of metastatic cells.

Awards and honours In 2016, Yaniv was Awarded a LE&RN Wendy Chaite Leadership Award. She received grants from the Horizon 2020 program, including €2m for her LymphMap project. Other awards and honors include: European Research Council grant (2014–2019), Israel Cancer Research Foundation Career Development Award (2012), Werner-Risau-Prize for outstanding research in vascular biology (2007), EMBO postdoctoral fellowship (2005–2007), Susan G. Komen Young Investigator Scholarship from the Lymphatic Research Foundation, now LE&RN (2006). She is a member of the European Vascular Biology Organization (EVBO), the North American Vascular Biology Organization (NAVBO), and the European Molecular Biology Organization (EMBO).

Worked examples

Example 1 — a first encounter with Karina Yaniv

Start with the simplest possible case. Write down what Karina Yaniv 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 Karina Yaniv 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 Karina Yaniv 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 Karina Yaniv

In research: Karina Yaniv 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 Karina Yaniv 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: Karina Yaniv is common in secondary-school and first-year university syllabi. It links to neighbouring topics Academic staff of Weizmann Institute of Science, Israeli biologists, Israeli women scientists, so understanding it makes those chapters shorter.
In everyday life: Look for Karina Yaniv 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.
