Background and activities
My research is focused on the evolutionary understanding of animal behaviour. I have conducted research on several issues related to parental care and sexual selection, and the interplay between the two processes. In addressing these topics, I have studied a wide range of fish and bird species. My current research is focused on three main issues: (1) Sex role dynamics, (2) Female ornamentation in relation to male mate choice and female‐female competition, and (2) Social and genetic mating systems; all of these relating to the larger issue of animal signaling. My current main model species is the two‐spotted goby (Gobiusculus flavescens), a small but ecologically important marine fish. The research is focused on reproductive dynamics, including behavioral and ecological factors that promote or restrain reproduction. I have also recently initiated a project on coral reef fish coloration, diversity and speciation. While the majority of my work has aimed to understand basic biological phenomena and processes, I am also involved in projects related to conservation biology and climate change. A current main focus is the effects of coral bleaching and coral mortality on reef fishes. My research involves collaboration with specialists around the world, and with students, post‐docs and senior researchers at my NTNU lab.

Teaching and supervision
I enjoy teaching and teach at all levels, from introductory undergraduate to PhD level. Topics for courses include general animal behaviour, communication and reproductive behaviour, sexual selection, and the theory and philosophy of biological science. I also enjoy supervising MSc and PhD students.
How To Do Science
Introductory course for the MSc in biology. I am responsible for teaching Theory of Science. The course is taught in English. The course manager is Associate Professor Thorsten Hamman.
BI3052 Study Design
This is a fairly new MSc course aimed to provide an extensive and hands-on introduction to good study design for MSc projects and in general. I teach the course together with professors Jon Wright (course manager) and Christophe Pélabon. My part of the course is on "Testing Hypotheses in Science", "Experimental vs Observational Studies", and "Laboratory vs Field Studies". The course is taught in English, and involves extensive student-teacher interaction and group assignments.
BI1003 Evolution, Behaviour og Ecology
First-year course in evolution, behaviour and ecology - the very first biology course in the study program of the Department. I am responsible for teaching behaviour, life history (and a bit evolution), alternating with Professor Gunilla Rosenqvist (I do odd-number years, she does even-number years). The course is tought in Norwegian, and includes lectures and a project on an assigned topic (group work). The course manager is Professor Lars Söderström.
BI 2045 Communication and Reproductive Behaviour
This course explores communication, sexual selection and reproductive behaviour in animals - and a little bit in plants. It fits into the curriculum towards the end of a BSc degree. The course is based on lectures and a supervised literature review project, and is taught in English (provided foreign-speaking course participants). The course starts on Tuesday 17 February. More info about the course can be obtained at trondamundsen.com, from the NTNU studies catalogue, and - once you have signed up for the course - at it:s learning.
MN 8000 Doing science: methods, ethics and dissemination
This course provides a down-to-earth introduction to the fundamental issues of doing science - the challenges and potentials of the scientific endeavour. It also deals with contemporary controversial issues related to the interaction between science and society. The course is a PhD course that is mandatory for all PhD candidates at the Faculty of Natural Sciences and Technology (the "NT Faculty"), normally to be taken at the start of the PhD study. The course is intensive course and is taught during January - February. MN 8000 is a collaborative effort by all departments at the faculty, with teachers from all departments as well. The course includes plenary sessions for all students (e.g. scientific writing, dissemination, history of science) and seminar sessions focusing on fundamental issues of doing science. These seminars are split by topic/department. I am responsible for the seminars for biology and biotechnology candidates (and potentially for biophysics). The course manager is Professor Signe Kjelstrup.
I like communicating science to lay audiences, and do so through lectures, newspapers, magazines, radio, etc. I also provide research news (mostly from research by others but sometimes also my own) on my twitter account https://twitter.com/Trond_Amundsen and sometimes also on my Facebook page (https://www.facebook.com/trond.amundsen.940; open profile).
