My current research interest includes:
Transport of phages in the subsurface
Here, I mainly focus on the transport of marine phages (also called tracer phages) in soil systems and aim to test their suitability as biological tracers for water flow or colloidal transport. With this aim, I use physical and biological quantification methods to reveal the changes of tracer phages during their transport in laboratory systems and under field conditions.
Non-specific phage-bacteria interactions
Phages and bacteria are the two most abundant biological entities in the subsurface soil environment. There, phages frequently collide into surfaces of different bacteria in a sorption/desorption manner, which is a potential but yet neglected aspect of phage-bacteria interaction in natural environments. In this respect, I aim to quantify the interaction between phages and non-host bacteria with different surface properties and understand its potential ecological implication.
The mycosphere is the microhabitat surrounding fungal mycelia. As mycelia vastly extend in soil (e.g. up to 20’000 km/m3 in a forest soil), the mycosphere is considered to be a hotspot for microbial interactions and activity. Few is known however on the effect of fungi and the mycosphere on phages. Here, I focus on understanding the role of fungi and the mycosphere for phage activities.
