• I am developing highly selective and sensitive biosensors for medical diagnostic applications.
• My key tasks include R&D project design and management related to:
• Design of biosensor architecture
• Design of new assay mechanisms for rapid diagnostic biosensors, targeting e.g. ctDNA, proteins, pathogens, hormones, or small molecules
• Biosensor material stack and its integration to mass manufacturing protocols
• Material surface functionalization

• In this position, I was developing highly selective and sensitive biosensors for medical diagnostic applications.
• My main responsibilities included:
• Determination of biosensor operational principle
• Evaluation of different electrochemical biosensor approaches
• Evaluation of substrate effect to biosensor performance
• Development of click-chemistry protocols to carbon nanotubes

• I was developing highly sensitive electrodes for detecting neurotransmitters in both physiological environments and the highly fouling in vitro environment. While commonly used electrodes quickly lose their sensitivity.

• I was studying the effect of surface stiffness on neural cell mechanics in cell culturing applications. My experimental part focused on using Atomic Force Microscopy to map elasticity of living cells on surfaces with.

• I was working in the microfabrication group, designing and conducting experiments on the production of catalytic silicon microreactors, based on ALD deposited TiO2 thin film and Pt-Nanoparticles.In this position I got.
• I developed a novel deep-trench (100 μm) lithography process for channel protection, as well as a spin-on-glass bonding process between TiO2/Pt-NP hybrid and glass. Furthermore, I designed a layer design to permit.

• I was working as a Scanning Electron Microscope operator.
• My job was to take SEM images and do chemical analysis with EDS to metallurgical samples. The job also included sample preparation and data analysis.

• I was working on the lithography team, developing the manufacturing process of MEMS accelerators and gyroscopes.This summer trainee position gave me excellent insight regarding how a state-of-the-art semiconductor.
• My main projects for the summer included creating two data banks, and also qualifying a new supplier. My tasks in these projects included project planning, data collection and documentation, creating new programs for.
• In addition to these given projects, I participated in developing the manufacturing process of a new product, where I created and optimized exposure programs, as well as created the required critical-dimension.

• I worked in a team that assembles MEMS-based combined gyroscopes and accelerometers.
• My responsibility was to monitor automated assembling machines, solve malfunctions in them, optimize processing parameters and to ensure product quality by doing visual inspection.
• I learned to understand the manufacturing cycle of MEMS devices, to recognize problems in the process and defects in the products, and to find the root cause of these problems.
