Background
Born in Trondheim in 1956. Graduated with cand.real. degree from UNIT - AVH in 1981 and was awarded her doctoral degree in 1987 from the same institution, with her research focus on photobiophysics and microorganisms. She continued to work as a postdoc at AVH with questions related to the biological effects of ultraviolet light.
In 1992, Kjeldstad was appointed associate professor in the Department of Physics in energy and environmental physics, and was promoted to professor in 2001. Since 1993, she has worked on issues related to UV radiation from the Sun, atmospheric physics and climate. She has 10 years experience with the Research Council of Norway’s climate programme, among other appointments. She has taught various topics in physics from foundation courses to master’s level courses. In 1999 - 2000, she took a sabbatical year at UMIST, Manchester, UK.
In January 2006, Kjeldstad was appointed head of the Department of Physics.
