Academic interests

I am a postdoctoral researcher at CEES, associated with REPEAT project. My current research focuses on an experimental assessment of the STR sequence variability on an environmental adaptation. Using various model organisms, such as medaka, zebrafish and Arabidopsis, I will investigate coding and non-coding STRs and their potential for functional modulation of regulatory mechanisms affecting the phenotype.

I completed my PhD in Molecular Genomics and Genetics at SARS Institute, University of Bergen, where I investigated genomic regulatory mechanisms underlying the control of developmentally important genes, as well as mutations affecting enhancers that lead to diseases and altered phenotypic traits.

As a researcher at UiB, I have worked with different aspects of salmon louse (Lepeophtheirus salmonis) biology, investigating its chemosensory and neuropeptide/hormonal systems and osmoregulation. At the same time, I have participated in development of a vaccine against L. salmonis and an investigation of mode of actions of potential anti-louse drugs.
