About me

I received my Ph. D degree with great distinction in June 2018 at the IOW, Germany. My PhD disseration elcuidated the link between aquatic bacterial diveristy and ecosystem functions using molecualr tools, particularly at the Baltic Sea areas, focusing on how bacteria cross marine-freshwater boundaries in terms of genetic and physiological responses to shifting salinity. Currently I am joining the Lab of Dr. Francisco Nascimento as a postdoctoral researcher. The aim of my current project is to develop an approach to quantify the biodiversity of meiofauna in the Baltic sediments, particularly nematodes as bioindicator organisms, from the pespectives of field invesgiations and experiments.

My collaborations and publications can be found at Researchgate.

Research

Microbial community composition varies over space and time, and the assembly mechanisms driving the variation remain unclear, because the entanglement of multiple mechanisms complicates the identification of causal relationships. Broadly, my research interests focus on the links between microbial biodiversity, ecosystem functions and the mechanims that underline the community assembly across environmental gradients or under adaptation scenarios.

Although several ecological principles were originally developed from plants or large animals, they have been also applied in microbial ecology in recent years. However, those ecological theories have not yet applied to explore microeukaryotic nematoes community. I believe that biogeography research of bacteria can be used as built-up assumptions to investigate benthic nematodes in the sediments and infer ecological processes guiding the patterns. Beside attempts to advancing ecological theory of meiofauna at sediment ecosystem, a high resolution quantification to their abudnance and biomass is important and critical for guiding management efforts aimed at maintaining biodiversity of meiofauna and related multifunctionality. To address those concerns, my current project integrates the conventionally taxonomical identification with DNA metabarcoding approach in order to generate a reference database that cataglogues the taxonomy of nematodes and archives their abundances to the best of our ability.
