Hanneke Jansen

Hanneke Jansen 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 Hanneke Jansen rather than just read about it. In short: Johanna Maria "Hanneke" Jansen is a computational chemist working at Novartis on multiple drug targets. She previously worked at Astra and at Chiron Corporation.

Key takeaways

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

Reference excerpt

Johanna Maria "Hanneke" Jansen is a computational chemist working at Novartis on multiple drug targets. She previously worked at Astra and at Chiron Corporation.

Education Jansen received her doctoral degree from the University of Groningen (The Netherlands) in 1995, studying computational medicinal chemistry. Her dissertation topic concerned 3D modeling of the melatonin receptor, including work on synthesizing and separating analytes to probe its chemistry. She completed a postdoctoral fellowship at Uppsala University in 1997. Her work there related to modeling receptor interactions of drug leads to judge their serotonergic or dopaminergic activities.

Research Much of Jansen's oeuvre uses in silico methods to study receptor biology, drug design, and drug-protein interactions. An early study (2000) while she was employed at Chiron looked at conformations of the anti-cancer treatment Taxol in nonpolar environments. In a 2012 commentary for Future Medicinal Chemistry, Jansen led a team of distinguished computational chemists in a call to action, namely that standardized data sets be used across the industry, and that sharing program code between groups at different companies and institutions should be mandated. A 2017 open-access study in PLoS One related some of Novartis' work - spearheaded by Jansen - to study the oncogenic protein RAS through inhibitors that targeted its inactive conformations.

Volunteer service Jansen has served the ACS division on Computers in Chemistry since at least 2007, holding multiple leadership positions. Outside of pharmaceutical work, she is perhaps best known as a co-Founder and Steering Committee member for the Teach-Discover-Treat initiative, which creates challenges for students and young professionals to design drugs against neglected diseases such as malaria or Trypanosoma using computational chemistry shared data sets and screens.

Worked examples

Example 1 — a first encounter with Hanneke Jansen

Start with the simplest possible case. Write down what Hanneke Jansen 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 Hanneke Jansen 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 Hanneke Jansen 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 Hanneke Jansen

In research
Hanneke Jansen 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 Hanneke Jansen 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
Hanneke Jansen is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century Dutch chemists, Computational chemists, Dutch women chemists, so understanding it makes those chapters shorter.
In everyday life
Look for Hanneke Jansen 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.
