- Teaching practical coarses for the undergraduate students (1st, 2nd and 3rd years since 1990-till now) and graduate students (Diploma).
- Teaching coarses of Analytical Chemistry (Chem 221), Instrumental methods of analysis (Chem 321) and general inorganic chemistry (Predental students), Transition metal chemistry (Chem 332), Organometallics (Chem 431), Chemistry of s- and p-block elements (Chem 232) (1996-till now).
The main topic of the plane of research is to prepare Fe(II) complexes of 2,6-bis(ethylthiomethyl)pyridine, 2,6-bis(tert-butylthiomethyl)pyridine, 2,6-bis(tert-butylaminomethyl) pyridine, 2,6-bis(benzoxazol-2-yl)pyridine and bis(pyrid-2-ylmethyl)amine. Also, the Cu(II), Co(II), Ni(II) and Zn(II) complexes of the previous ligands are prepared. These complexes are under study as polymerization catalysts. In prenciple the ferrous copmplexes shall be more promising, according to previously reported data, but the other complexes will not be discarded. Four single crystals suitable for X-ray analysis were also prepared and their spectra were resolved and give promising results. Those are the Ni and Zn complexes of 2,6-bis(tert-butylthiomethyl)pyridine and Co and Zn complexes of 2,6-bis (tert-butylaminomethyl)pyridine.
The second goal of this trip is to prepare a single crystal supramolecule of 2,6-dimethyl-pyridine N-oxide in a strip form. The crystal structure is solved and gives a promising structure. This work is now under preparation for publication.

2. Alexander von Homboldt fellow from 1-12-2004 to 30-11-2005 , Faculty of Science, Chemistry Department, Konstanz University, Germany. The main topic of the research program is to prepare new carbene complexes of Cr and W. The reactivity of these carbene complexes with different electron donating or withdrawing groups is also checked. Synthesis of organic compounds from these carbene complexes is also tested. The complexes are characterized using elemental analyses, IR, mass, 1H and 13C NMR and X-ray spectroscopy.

3. Alexander von Homboldt fellow from 1-7-2010 to 30-9-2010 , Biotechnology Department, Wildau University, Germany. In this project, some antibiotic drugs in the hydrochloride form were chosen to study their properties from the analytical point view. The purpose of this investigation was directed to propose sensitive, accurate and reproducible analytical and electroanalytical methods of analysis that can be applied to determine important the drugs under investigation in pure and pharmaceutical preparations. For this purpose the work deals with the use of both ISEs (SPCPEs, CPE, PVC, caoted wire and coated grafite) and electrochemical techniques (cyclic voltametry, differential pulse voltametry, amperometry, etc) in the determination of the suggested drugs in pharmaceutical preparations.
