Working as an adjunct assistant professor my main responsibilities are lecture with students (biochemistry, toxicology, pharmacology) and research in toxicology, forensic, biochemistry and immunology and also metabolomic research. Scientific assistance of students as part of cooperation with International Federation of Medical Students' Associations - IFMSA program. Head of Department of Toxicology.

As a Head of Laboratory I play a vital role in the overall safety of the laboratory and I'm responsible for managing the daily operations of the lab. I take responsibility for all aspects of the lab, including but not limited to: instruments/equipment, users of the lab, and supplies needed to ensure the lab runs smoothly. Analysis of drugs, pesticides in environmental samples.

Working as a assistant and researcher in mass spectrometry and clinical medicine.Responsible for students, lecture and co-operation with other departments of Warsaw Medical University.

I was on post-doc in the Institute of Animal Reproduction and Food Research of Polish Academy of Sciences in Olsztyn, Poland as independent researcher in metabolomic and proteomic research. The Project REFRESH - Unlocking the potential of the Institute of Animal Reproduction and Food Research for strengthening integration with the European Research Area and regional development was my main project in the Institute. My main responsibilities was developed new analytical methods for polyphenols in food by GC-MS and LC-MS (or Q-TOF) and proteins by MALDI-TOF/TOF analysis as a target and non-target analysis.

My main responsibilities in anti-doping lab was supervision of the standard operating procedures accredited in Polish Center of Accreditation PN-EN/ISO-EC 17025 and in World Anti-Doping Agency (Montreal, Canada). I developed new methods for detection designer steroids in urine, blood samples and other biological samples. My work was mostly focused in target analysis, but also developing new metabolites of steroids and stimulants and other known and unknown hazardous chemicals. During my time in DADR I extended my knowledge for analytical chemistry, metabolism of pharmaceutics, mass spectrometry and isotope ratio mass spectrometry, chromatography, mathematical methods in measurement data evaluation and ability to carry out chemical measurements using the mass spectrometry. Development and application of analytical methods for detection of pharmaceuticals and designer drugs in urine and other matrices by means of GC-MS, GC-MS/MS, IRMS, prep-HPLC.Studies on metabolism of pharmaceuticals in man, horses, including design of administration studies, and conducting the research, preparation of grant proposals and manuscripts, and presentation of research work at scientific conferences and supervising studentsPart of my job was to handle and control all of measurement equipment (Agilent Technologies, Thermo Finnigan) with validation includes.
