• PhD project: application of modern mass spectrometric techniques in environmental analysis. Investigation of microbial metabolism of hazardous pollutants in the environmental samples using GC-MS and HPLC-MS methods.
• Contract analytical activities. Got acquainted with impurity profiling and ADME studies of drug candidates and the everyday service work for synthetic laboratories.
• Fundamental gas-phase ion chemistry studies under the leadership of, Károly Vékey. Development of novel experimental techniques for the investigation of internal energy effects of electrosprayed ions. Technique was also successfully applied to structure elucidation of molecules, and investigation of solvated metal cations.
• From 1999 introduction of mass spectrometric diagnostic methods for the diagnosis of inborn errors of metabolism, first in Eastern Europe. Major role in this project, and still involved in the development of a Hungarian screening program.
