I get excited about topics related to environmental remediation processes using environmentally sound nano-materials. This interest of mine is drawn on previous research stints in Italy and Switzerland focusing on photocatalysis. As an experimentalist, I play on different synthesis parameters – inspired from out-of-the-box thinking, to improve the desirability of field-scale application. Furthermore, I am interested in finding answers to the fundamental behaviour of synthesized nano-materials through different characterization techniques

Minerals form everyday in all kinds of environments, including soils and groundwater. They take ions from the aqueous solution and they incorporate them inside their structures to build their “bodies”. In that process they can trap some contaminants, for example, toxic trace metals. My job is to study how this process occurs in green rust, the mineral that will be protagonist of our project. I hope that my experiments can help other people to find a new way to clean-up contaminated groundwaters.

My research interests are focused on the synthesis and mineralogical and chemical characterization of new Layered Double Hydroxides and their possibilities of intercalating organic pollutants as well as heavy metals. During my master’s thesis I already studied the possibilities of intercalating potassium permanganate in the interlayer of layered double hydroxides. I am now looking forward to linking my laboratory work with the practical application for remediating contaminated soil and groundwater in our interdisciplinary project.

Through computation, we may have a deeper understanding of mechanisms of chemical reactions. The combination of computation and experiment becomes more effective and attractive to investigate chemical reactions. My main work is using DFT methods to explain and verify the results obtained from experiments, to provide experimental ESRs with new ideas and guidance such as studying reaction mechanisms of injection materials (like layered double hydroxides and green rust) and contaminants, designing different reactions by changing the molecular structures, and designing new materials by modeling and calculation.

In general, I seek to promote the responsible and sustainable use of our natural resources, which includes remediation of contaminated sites and ensuring clean water supply. Having worked on an acid mine drainage site and having investigated the mineralogy and geochemical interrelations of a heavy metal [high field strength element (REE,Y, Zr, Nb, Ti, Th)] deposit during my studies, I am most interested in the (aqueous) geochemistry and mobility of heavy metals, fluid-mineral interactions, and phase transformation reactions. Therefore, with my research within this project focusing on experimental investigations on contaminant reduction, I aim to gain a detailed understanding of the geochemical behavior and reaction kinetics of the pollutants under green rust-based remediation in contaminated soils and waters.

Over the last years, I have become especially interested in the kinetics and thermodynamics driving reactions at the solid-liquid interface. I find these processes interesting because I feel they can provide us with an insight on why fluid-solid interactions take place in the first place. For me the challenge lies in linking these nanoscale processes to the behaviour of pollutants/compounds at a larger scale. Understanding the nature of liquid-fluid interaction allows for a better prediction on how pollutants/compounds move within the natural environment, making it a socially relevant research topic.

My research interest is focused on the development and application of sustainable novel (nano)materials for environmental remediation, specifically on the abatement of heavy metal and organohalogenated contaminants. For my master’s dissertation, I worked on the use of encapsulated iron oxide nanoparticles in nanoporous materials for the removal of heavy metals and the recovery of precious and critical metals. My future work at GFZ will be focused on determining the compositional, structural and reactivity changes of various novel green rust phases during decontamination of groundwater.

My scientific interests are focused on Applied Mineralogy, in particular Technical and Environmental Mineralogy, specializing on microstructural techniques for the investigation of mineral properties. I am attracted to research on innovative and sustainable materials aimed at solving issues related to water pollution and soil remediation. My area of research is focused on the quest for innovative and environmentally friendly porous materials, e.g. zeolites, which are promising tools against environmental threats.

My research interests include the behavior and speciation of trace elements in natural environments, especially when associated with metal oxide minerals. Previously, while enrolled at the University of Arizona, I researched how mineralogical and elemental speciation changes associated with oxidative weathering of sulfide mine tailings control the bioavailability of trace elements in in vitro systems. At the Karlsruhe Institute of Technology, I will be studying interactions of trace metal (loid) contaminants with green rust transformation products.

My research interests lie in hydrogeochemical modeling for characterizing the chemical and transport processes in a groundwater system. Coming from a place where groundwater is abysmally contaminated with naturally occurring Arsenic, this research area has always fascinated me. During my MSc. thesis, I worked on studying the fate of solutes and contaminants in groundwater of Gaziemir region, Turkey. My research work at Amphos 21 will be focused on studying the effect of CO2 and O2 on contaminant mobility with the help of reactive transport models.

My interests are focused on laboratory synthesis as well as chemical and mineralogical investigations and characterization of artificial and natural compounds, particularly of layered double hydroxides. Especially interdisciplinary topics with practical applications are of interest for me. Therefore I have passed a work experience in the Helmholtz Centre for Environmental Research Leipzig (UfZ) on the subject of degradation of organic pollutants and heavy metals. I am also familiar with modelling of chemical reactions using PhreeqC.

My personal research interest includes generally the wide field of hydrogeology. In detail I’m interested in the hydro-chemical processes on field scale. As I was confronted with arsenic, antimony and tetrachlorethen in groundwater in the context of my Master’s thesis and my work, I have some questions about their occurrence. This includes questions about the source of contaminants, processes/reactions during transport and about possible remediation techniques. In this work I will focus on the development of a new in-situ remediation technique using green rust and how this method will work in a natural environment in combination with a detailed investigation of the test site.

I am interested in natural processes in environmental compartments and their interfaces. Besides mitigating anthropogenic pressures on these, remediation is a big challenge of our generation. In this project I am on the one hand interested in the analytical and theoretical means of describing, assessing and working with these large scales. On the other hand, with a background in (computational) chemistry, in the gap that remains between the molecular and macroscopic scale.

My research interests focus on groundwater and soil characterization and remediation, with the main goal to address and minimize health-related impacts and environmental issues. During my thesis, I characterized and performed geochemical analysis on a contaminant plume derived from a landfill leakage in a small basin in Vitoria, Spain. At AECOM/URS I will be working on contaminated site characterization and Layered Double Hydroxides (LDH) injection to better understand their interaction with chlorinated compounds, their distribution, and mobility in the porous media.
