Research

I am a researcher at NTNU with a background in biology, stress physiology and environmental research. I have experience investigating physiological and molecular responses to environmental stress, with a particular focus on marine copepods. During my PhD in the Yap lab, I investigated how stressors such as temperature and anthropogenic noise affect the physiology, survival and life history of Calanus finmarchicus. I am now working as a researcher on fish parasites, health and welfare and I am investigating how different conditions and handling procedures associated with aquaculture affect salmon lice physiology and performance. My current work focuses on salmon lice biology, including physiological responses, infestation capacity and adaptation processes.

Student explores ecology impacts in Norway through Ohio State global research program

Erin Murray, an exchange student from Ohio State University, shared her experience in Norway with the TRONDBUSS program at NTNU. She joined our team during fieldwork were we investigated the impact of offshore windfarm noise on copepods.

Effects of environmental challenges on physiological and life-history performance of a small marine copepod, Calanus finmarchicus.

I presented my latest work on copepods at the SEB 2024 conference in Prague. In the video, I present my results on eggs, nauplii, adult males and females Calanus finmarchicus.

Recipient of Best Student Oral Presentation Award 2024 from the World Association of Copepodologists

This summer 2024, I had the opportunity to attend the 15th International Conference on Copepoda in Hiroshima. I presented my work on Calanus finmarchicus and was honored to receive the 2024 Best Student Oral Presentation Award!

Effects of heat stress and oxidative stress exposure on different life stages of copepod Calanus finmarchicus
