Research

I am working as an Assoc. Prof. / senior researcher at the Department of Biotechnology, NTNU. My main research activites are wihtin computational and synthetic biology, and biophysics. In our lab, we employ various methods, such as microfluidics, single-cell arrays, and high-throughput screening. We work with a large sellection of microorganisms including Corynebacterium glutamicum, Escherichia coli, Pseudomonas putida KT2440, psychrophilic Pseudomonas, Psychrobacter spp., Pichia pastoris,  Streptomyces albus, S. coelicolor, S. lividans, Synechococcus sp. PCC 7002, Saccharomyces cerevisiae, and Thermus thermophilus.

Projects

EU-H2020 – Advanced toolbox for rapid and cost-effective functional metagenomic screening – microbiology meets microfluidics.

EPSRC-UK – Design the Future 2: Thinking Soils: Engineered bacteria as computational agents in the design and manufacture of new materials and structures.
