Ingrid Eftedal

Ingrid Eftedal 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 Ingrid Eftedal rather than just read about it. In short: Ingrid Eftedal (born 3 July 1965) is a Norwegian molecular biologist and barophysiologist who is employed at the Faculty of Medicine and Health Sciences at the Norwegian University of Science and Technology (NTNU). At NTNU, she has been a senior researcher and head of the barophysiology research group.

Key takeaways

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

Reference excerpt

Ingrid Eftedal (born 3 July 1965) is a Norwegian molecular biologist and barophysiologist who is employed at the Faculty of Medicine and Health Sciences at the Norwegian University of Science and Technology (NTNU). At NTNU, she has been a senior researcher and head of the barophysiology research group. She has also been a dean and associate professor at the Faculty of Nursing and Health Sciences at Nord University. Eftedal holds a PhD in molecular genetics.

Career and research She graduated as a civil engineer in biophysics and medical technology from the Norwegian Institute of Technology (NTH; now NTNU) in 1989 and received her doctoral degree (dr.ing.) molecular genetics from NTH in 1993. She was a postdoctoral fellow at the École supérieure de biotechnologie Strasbourg and has worked as a molecular biologist at Rigshospitalet in Copenhagen, as head of the Department of Medical Genetics at St. Olav's University Hospital, and as dean of research at the Faculty of Nursing and Health Sciences at Nord University. She is employed at the Faculty of Medicine and Health Sciences at NTNU, where she has been a senior researcher and group leader. She has also held a position as an associate professor at Nord University. She was a member of the national Forensic Medical Commission from 2007 to 2012, appointed by the Ministry of Health and Care Services. She was also a member of the Preimplantation Diagnostics Committee from 2008 to 2010. Eftedal's research studies how the human body adapts to extreme environments using evolutionarily developed mechanisms, and how diving sickness affects immune cells and inflammatory processes. The goal of the research is to contribute research-based knowledge that can prevent health damage to divers and others who are in physically challenging environments. A large part of the research is related to offshore diving. This form of diving has been crucial to Norway's oil and gas industry and is also important for the development of several renewable energy sources, such as wind and wave power. In 2022, Ingrid Eftedal was one of the finalists for "Name of the Year in Academia" award of the newspaper Khrono.

Worked examples

Example 1 — a first encounter with Ingrid Eftedal

Start with the simplest possible case. Write down what Ingrid Eftedal 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 Ingrid Eftedal 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 Ingrid Eftedal 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 Ingrid Eftedal

In research: Ingrid Eftedal 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 Ingrid Eftedal 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: Ingrid Eftedal is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1965 births, 20th-century Norwegian women scientists, Academic staff of Nord University, so understanding it makes those chapters shorter.
In everyday life: Look for Ingrid Eftedal 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.
