Kort om meg

Kristian Thorsen is an Associate Professor in Control Engineering at the University of Stavanger (UiS), Norway. He is currently the leader of the Cybernetics and Systems Biology Laboratories research group.

Teaching and research interests

Cybernetics, dynamic systems, systems biology, synthetic biology, nonlinear systems, control engineering, control theory, mathematical modeling, electronics, embedded systems, signal processing, automation, robotics.

My interest in teaching comes from my own enthusiasm for science and engineering. In my approach to teaching I seek to combine a thorough understanding of theory, facts, and logic reasoning with practical applications and solving of industry relevant problems. I prefer to give courses that bring students into an engineering culture.

My research is focused on using concepts from control engineering to understand regulation in biological systems and on using mathematical models to understand and predict biological phenomena in single cells and in populations of cells and their environment.

Teaching experience

ELE340 Electronics and embedded design (10 ECTS)

Offered in the fifth semester of the bachelor’s degree in electrical engineering. This course gives insight into structured design of embedded systems, i.e., microprocessor-based systems for measurement and control. The students are organized into project groups and project management and a multidiscipline attitude is emphasized. Design exercises in the laboratory forms a main part of the course.

Teaching competence

Below is a list (in Norwegian) of formal courses and seminars that I have taken or participated in to build up my competence in university pedagogics and didactics:

Kollegialt læreprogram for nye undervisere (50 timer) 

I regi av Universitetet i Stavanger, Institutt for data- og elektroteknologi. Periode august – desember 2013. Opplegget tilsvarer det opplegget som i dag på UiS heter NyTi. 

Basiskurs Universitetspedagogikk (100 timer) 

For vitenskapelig tilsatte ved Universitetet i Stavanger. Periode desember 2016 til august 2017. 

Seminar: «Women in International Higher Education and STEM Fields» (37.5 timer, 5 dager) 

Erasmus+ Staff Week HSB Hochschule Bremen. Fokus for programmet var hvordan en kan legge opp undervisning og mentorordninger som bidrar til å bedre representere og holde på kvinnelige studenter, samt hvordan en kan motivere og rekruttere for økt kvinneandel i teknologisk rettede høyere utdanninger. Mai 2019.

Veilederkurs «UiS PhD-Supervisory Qualification Programme 2019» (100 timer)  

Periode januar – juni 2019.

Diverse utdanningsfaglige seminarer (25 timer) 

UiS har siden 2019 og utover hatt et kvalifiseringssystem for utdanningsfaglig kompetanseder det arrangeres utdanningsseminarer både av UiS sentralt og fakultetene. Disse seminarene har typisk en dag eller en halv dags lengde. Jeg har deltatt på 6 slike seminarer, med et totalt timeantall på ca. 25.
