Research interests

- molecular microbial ecology
- microbial diversity
- environmental and anthropogenic factors influencing microbial communities and processes
- bioinformatics and multivariate statistics

I am investigating the effect of milkfish mariculture in the Philippines on microbial communities, using mostly molecular tools such as next generation sequencing. Specifically, I am interested in the distribution of bacterial pathogens in the mariculture areas (ACUTE project). Furthermore, I am a collaborator in the project MIRACLE, which focuses on the role of bacterial communities in shrimp pond aquaculture and disease occurrence. Apart from anthropogenic impacts, I am also investigating natural variation in microbial communities and their activity in mangrove sediments subject to tidal fluctuations (TIdES project). The overall goal of my research is to gain a better understanding of the factors influencing microbial communities and microbially mediated processes, their responses, and repercussions for coastal ecosystems.
