Titia de Lange

Titia de Lange is a chemistry 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 Titia de Lange rather than just read about it. In short: Titia de Lange (born 11 November 1955, in Rotterdam) is the Director of the Anderson Center for Cancer Research, the Leon Hess professor and the head of Laboratory Cell Biology and Genetics at Rockefeller University. De Lange obtained her Masters on "Chromatin structure of the human β-globin gene locus" at the University of Amsterdam in 1981, and subsequently her PhD at the same institution in 1985 with Piet Borst o…

Key takeaways

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

Reference excerpt

Titia de Lange (born 11 November 1955, in Rotterdam) is the Director of the Anderson Center for Cancer Research, the Leon Hess professor and the head of Laboratory Cell Biology and Genetics at Rockefeller University. De Lange obtained her Masters on "Chromatin structure of the human β-globin gene locus" at the University of Amsterdam in 1981, and subsequently her PhD at the same institution in 1985 with Piet Borst on surface antigen genes in trypanosomes. In 1985 she joined Harold Varmus's lab at the University of California, San Francisco. Since 1990 she has had a faculty position at the Rockefeller University. In 2011, de Lange received the Vilcek Prize in Biomedical Science. In 2013 she won a Breakthrough Prize in Life Sciences, worth $3 million, for her research on telomeres. In 2000 she became correspondent of the Royal Netherlands Academy of Arts and Sciences.

Career Titia de Lange attended the University of Amsterdam where she received her bachelor's and master's degree in biochemistry. She also earned her Ph.D. from the University of Amsterdam while working at the Netherlands Cancer Institute. In 1985, she accepted a postdoctoral fellowship position at the University of California, San Francisco. In 1990, de Lange started her own lab at Rockefeller University. She is currently the Leon Hess Professor as well as the Director of the Anderson Center for Cancer Research at Rockefeller University. She won the Breakthrough Prize in Life Sciences in 2013 for her research on telomeres, illuminating how they protect chromosome ends and their role in genome instability in cancer by mapping the complex of molecules that loops the strands together and protects them. In addition to making headway in revealing the structure of DNA, her research has implications for the understanding of aging and cancer.

Worked examples

Example 1 — a first encounter with Titia de Lange

Start with the simplest possible case. Write down what Titia de Lange claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, 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 Titia de Lange 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 Titia de Lange 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 Titia de Lange

In research: Titia de Lange appears in chemistry 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 Titia de Lange 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: Titia de Lange is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1955 births, 21st-century Dutch chemists, Dutch biochemists, so understanding it makes those chapters shorter.
In everyday life: Look for Titia de Lange 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.
