Background and activities
I am leading an interdisciplinary lab operating within the fields of biophysics, computational and synthetic biology. Our main focus is both understanding and controlling transcriptional and translational processes in microorganisms. We employ a range of methods, including microfluidics, single-cell arrays, and high-throughput screening. We work with a wide range of microorganisms, such as Chlamydomonas reinhardtii (chloroplast), 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, Vibrio natriegens and Thermus thermophilus.
