Specialization: 
Soil microbiology, arctic soil (degraded permafrost soil)
Specialization: 

My research is focused on the identification and determination of microbial community composition, microbial activities, and processes in organic matter mobilization/stabilization in degraded permafrost soil. To achieve these goals I perform field and laboratory experiments, and comparative analysis of soil microbial community under different hydrological scenarios of degraded permafrost soil. In this research isotope-labeling and metatranscriptomics (“double-RNA” metatranscriptomics), approaches will be applied to provide detailed insight into complex functional dynamics of microbial communities, metabolic and enzymatic activities in degraded permafrost soils.

Aquatic Biogeochemistry

Hi,

I am enthusiastic about how the redox reactions driving Fe and Mn mineral transformations, influence the biogeochemical cycle of nutrients (N and P) and transition metals (As, V, and REE) in redox transition boundaries found in aquatic environments. For this, our laboratory applies diverse bioelectrochemical and geochemical approaches able to explore mineral transformations due to redox reactions occurring at the microscale (mm). This allows us to understand past and present environments, and to improve management strategies necessary to maintain the water quality of natural and engineered reservoirs.

Plant Defense (Ecology) and Botany

Brief CV: 

Brief Background

I am from Papua New Guinea, a tropical country in South Pacific and located north of Australia. My research interests are in plant taxonomy and ecology, particularly on investigating how plants response to herbivorous insects' attack using leaf traits (physical and chemical) to defend themselves from their enemies as well as on understanding niche partitioning in plants using mechanisms of sympatric and allopatric speciation respectively.

To understand interactions between plants, vertebrates (bats, birds) and arthropods, our team (https://multitrophicinteractions.blog/projects/) is working on complex food web structures on global scale (latitudinal and vertical gradient studies).

Microbial biomarkers, stable isotopes
Specialization: 

I am at the SoWa Institute a PhD student at the department of Ecosystem biology, University of South Bohemia in České Budějovice with the supervision of Dr. Travis Meador. I have long-term work experiences as a student assistant at the Institute MARUM (Center for Marine Environmental Science, Bremen, Germany) in the Workgroup of organic Geochemistry lead by Prof. Dr. Kai-Uwe Hinrichs. My main interests are reconstructing Paleoenvironments by applying microbial membrane biomarkers and analysing microbial activity and metabolism by applying Stable Isotope Probing (SIP) experiments. I have experience in analysing these biomarkers on different techniques, such as GC-FID/MS/IRMS, LC-QToF-MS, QQQ and FTICR-MS. Also developing new methods for analysing biomarkers with different techniques takes a big part of my working experience. My research focuses on determining and quantifying fungal C-turnover rates and mechanisms in subsurface ecosystems by applying dual stable isotope probing (δ13C + δ2H) analysing the membrane biomarkers.
