Reference excerpt

Unnur Anna Valdimarsdóttir (born 1972) is a professor in epidemiology at the Faculty of Medicine of the University of Iceland. Her research focuses on the role of trauma and other life adversities in health and disease development.

Professional experience Unnur completed her matriculation examination from the natural sciences track of Akureyri Junior College in 1992 and a BA in psychology from the University of Iceland in 1996. She started a doctoral programme at Karolinska Institutet in Stockholm in 1999 and completed her doctorate in clinical epidemiology in 2003. Her doctoral dissertation, "The loss of a husband to cancer: additional and avoidable psychological traumata", focused on widows' health and adjustment after their husbands'' sickness and death due to cancer. From 2003 to 2006, Unnur continued working as a post doctoral fellow at Karolinska Institutet. There she laid the foundation for her research plan to the present. In 2007 Unnur was hired as an associate professor in epidemiology at the Faculty of Medicine at the University of Iceland and was promoted to professor in 2012. She served as Deputy Dean of the Faculty of Medicine from 2013 to 2017. Unnur became the first head of a newly founded cross-disciplinary master's and doctoral programme in Public Health in 2007 and served in that capacity until 2017. She has taught courses for medical students and graduate students in epidemiology and other public health-related subjects and has also supervised many master's and PhD students. Unnur has been an adjunct professor at the Department of Epidemiology at Harvard TH Chan School of Public Health in Boston since 2013, and a guest professor at the Department of Medical Epidemiology and Biostatistics at Karolinska Institutet since 2015. She has also been active in advising students and research collaboration with scholars of those institutions.

Research The overarching aim of Unnur's research team is to advance knowledge on, on the role of trauma and other life adversities such as loss of a loved one, diagnosis of cancer, natural catastrophes, and violence, in the development of various diseases. She has published her findings in approximately 150 scientific articles. Several of these articles have been published in some of the world's leading scientific medical journals, e.g., The New England Journal of Medicine, JAMA, Lancet Psychiatry, and BMJ. Unnur has also presented her findings in invited lectures at institutions of foreign universities and at international conferences.

Acknowledgements and grants Unnur has received many acknowledgements for her work, including: Science and Technology Incentive Award (2010), award from the Award Fund of Þórður Harðarson and Árni Kristinsson in medicine and related fields (2017) for outstanding research achievements. In 2017, she was the first woman to be named Female Academic of the Year. Unnur has received many research grants, including a recent Grant of Excellence from The Icelandic Centre for Research, and a Consolidator Grant from the European Research Council for research on the genetics of varying health trajectories following trauma.

Personal life Unnur's parents are Guðrún Jónsdóttir (b. 1939), hairdresser, and Valdimar Ágúst Steingrímsson (b. 1939), patrolman. Her siblings are Pétur Valdimarsson (b. 1966), graduate in business administration, and Jóna Ellen Valdimarsdóttir (b. 1977), registered nurse.

Worked examples

Example 1 — a first encounter with Unnur Anna Valdimarsdóttir

Start with the simplest possible case. Write down what Unnur Anna Valdimarsdóttir 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 Unnur Anna Valdimarsdóttir 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 Unnur Anna Valdimarsdóttir 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 Unnur Anna Valdimarsdóttir

In research: Unnur Anna Valdimarsdóttir 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 Unnur Anna Valdimarsdóttir 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: Unnur Anna Valdimarsdóttir is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1972 births, Academic staff of the University of Iceland, Harvard T.H. Chan School of Public Health faculty, so understanding it makes those chapters shorter.
In everyday life: Look for Unnur Anna Valdimarsdóttir 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.
