Project: Control of self-assembly of organic semiconductors for transistor applications. Solution deposition at different conditions to tune the order and microstructure of the active layer to correlate to the charge carrier transport in the device.

My duties included sampling and analysis of raw materials: dry matter, ash, protein (Kjeldahl method), fat (Soxhlet method). Factory and laboratory were newly built, so I took part in audit preparations and audit process (Good Laboratory Practice, laboratory safety and environmental protection).

I was chemistry tutor for pupils from middle school, high school and also university attendants.

I was responsible for preparing samples and the determination of pirimiphos methyl in gluten and wheat. The method which I used was Gas Chromatography (GC with NPD detector). What is more, I made analysis of ethanol in spirits (GC with FID detector). I documented, interpreted the results and if it was necessary I performed calibration/ recalibration/changing parts of the chromatograph.

I was responsible for measures necessary for preparing calibration new FT NIR Analyzer (HPLC, refractometer and spectrophotometer).

I had opportunity to train myself in chemical/food industry environment. I gain knowledge about processes and machines used in glucose-fructose syrup production and also laboratory methods necessary to determine subproducts quality (HPLC, pHmeter, spectrophotometer, refractrometer, conductometer and others).

I was responsible for preparing and weighting soil samples. Conducting measurements with: AAS technique, weight technique, titrate technique, spectrophotometric, conductometric. Also I was responsible for archiving results as a chemical reports. As a lab technician I used to work under the ISO 17025 regime.

Master's thesis: Design of inhibitors of L-methionine ɣ-lyase (Software: Molden, Gaussian 09, Autodock).

Engineer’s project: Matrix effects for the determination of lead chemical vapor generation method (method: HG ICP-OES).
