Summary

 

INHALATION TOXICOLOGY AND PHARMACOLOGY

Lung's alveolar epithelium is the most permeable interfacial barrier of the human body. The risk for adverse respiratory effects induced by the inhalation of nanoparticles at the lower airways depends on their hazard towards lung surfactant, cells, and organisms; and on its exposure i.e., lifetime and concentration of the inhaled nanoparticle, as well as the distribution of its deposition in the respiratory airways. I am developing novel advanced in vitro models that can be used for toxicological and pharmacological testing. I am employing cells cultured at the air-liquid interface mimicking the epithelial airways, also including lung surfactant and under physiological respiratory mechanics. These models are challenged with nanoparticles to unravel the mechanisms of lung surfactant interaction and cellular uptake. These approaches will help to gain further understanding of the role inhaled toxicological nanoparticles have in compromising our breathing, initiating lung inflammatory processes and airways diseases. The acquired knowledge will be applied in designing novel and better pharmacological drugs.

Molecular Sensing and Remodeling at the Respiratory Airways

I am interested in how airways cell membranes sense and remodel. I am aiming to better understand the manner plasma and intracellular membranes communicate with their micro/nano-environment, including foreign biofunctional materials, nanoparticles, and micro/nano-organisms. I want to gain knowledge on how they perceive stimuli and decode signals, and how they encode their responses and trafficking mechanisms. I am interested in learning the way they harbour supramolecular assemblies and favour particular lipid-protein spatiotemporal arrangements. In particular, I focus my research on the molecular basis for cellular communication during innate immune relevant processes. 

Respiratory Cell and Molecular Immuno-Physics and -Engineering


In general, I am interested in the molecular basis for cellular communication during immunological relevant processes at the respiratory airways, such as acute and chronic inflammation. I am focusing on lipid-protein spatiotemporal interactions, its distribution and dynamical functional architectures at the micro- and nano-scale. In particular, I am aiming to understand the mechanisms of membrane sensing and remodelling in for example T-cells at the resting state, during T-cell activation and at the Immune Synapse. For this purpose, I am developing a novel manner to fine-manipulate and control the activation of immune cells combined with the use of high-advanced 4D micro-/nano-scopy and spectroscopy combined with a detailed data analysis and quantification.
