Süleyman Z. CAN (Head of Laboratory)

He studied Chemistry Education at the Middle East Technical University (METU) Faculty of Education from where he graduated in 1999.

Between 1999 and 2002, he conducted the master of science degree studies entitled ‘Studies on Anatolian Medieval Glazed Ceramics using Atomic Spectrometry’ under the supervision of Prof.Dr. O. Yavuz Ataman of the METU Department of Chemistry. He received his PhD degree in chemistry from the University of Maryland - College Park (Maryland, USA) with a study on ‘Molecular Structure and Organization of Organic Monolayers at Air/Water Interfaces’. Following completion of the study under the supervision of Professor Robert A. Walker in 2008, he joined the National Institute of Standards and Technology Biophysics Group for a postdoctoral study. Süleyman Can has been working in the Inorganic Analysis Laboratory of TÜBİTAK UME since 2010 in fields of chemical metrology, inorganic analysis, atomic spectrometry, preparation and certification of reference materials, interlaboratory comparisons etc.

Betül ARI

Betül Arı graduated from the Middle East Technical University, Chemistry Department in 2007 and obtained her MSc. degree in analytical chemistry under the supervision of Prof. Dr. O. Yavuz Ataman in 2009 from the Middle East Technical University. Following graduation, she started to work at TÜBİTAK UME as a researcher in the chemistry laboratories. As her experience is centered on atomic spectrometry, she has worked in the inorganic analyses area. Within the scope of an EU funded development project, she worked for one year as a guest researcher at the Institute of Reference Materials and Measurements (IRMM) in Belgium and gained experience in chemical metrology applied to inorganic chemical reference measurements, primary measurement techniques, isotope dilution mass spectrometry and quality systems. She has been participating in work on processing and certification of candidate reference materials and national proficiency test materials in inorganic matrices.  Additionally, she has been working on expanding the measurement capabilities of TÜBİTAK UME in inorganic chemistry by participating in international comparison studies organized by CCQM.


F. Gonca Coşkun received her B.Sc. and M.Sc. degrees in Chemical Engineering from Ankara University in 1993 and 1995, respectively. She received her Ph.D. degree in Civil (Environmental) Engineering from the Graduate School at the City University of New York as a Robert E. Gilleece fellow in 2003. She worked as a research assistant between 1993 and 1997 at Ankara University and between 1998 and 2003 at the City University of New York. She was employed by the Ministry of Environment and Forestry (Provincial Directorate of Istanbul) between 2004 and 2009. Since 2009, she has been working in the TÜBİTAK UME Inorganic Chemistry Laboratory as a senior researcher. Her work has mainly focused on CIPM key comparisons and the EMRP projects in which Inorganic Chemistry Laboratory participates, the proficiency tests organized by the TÜBİTAK UME Chemistry Laboratories, and the research projects on the production of certified reference materials.


Oktay Cankur graduated from the Middle East Technical University, Faculty of Education, Department of Chemistry Education in 1995. He received his MSc. degree in Analytical Chemistry from the Faculty of Arts and Sciences, Department of Chemistry of  the same university in 1998. He completed his Ph.D. studies on method development in analytical chemistry, on-line preconcentration and method validation in 2004. During his M.Sc. and Ph.D. studies between 1995-2004, he worked as a research and teaching assistant in the Department of Chemistry, Faculty of Arts and Sciences, at METU. In 2004, he was awarded a TÜBİTAK NATO-B1 Post Doctoral Fellowship and conducted postdoctoral studies on the speciation of selenium in different samples using chromatography and ICP-MS in Prof. Dr. Joseph Caruso’s Research Group at the University of Cincinnati (Ohio, USA)

He started to work in the TÜBİTAK UME Chemistry Group Laboratories as a senior researcher in 2006. He was the head of the same unit between 2009 and 2011. During his studies at TÜBİTAK UME, he was involved in national and international research and development projects as a coordinator and researcher as well as in the preparation and submission stages. He took an active role in the preparation and the coordination of EU supported projects. He was also involved in international key and pilot comparison studies and contributed to the development of the measurement capabilities of TÜBİTAK UME.  He participated in the organization of proficiency testing schemes and data evaluation. He served as a trainer In Method Validation and Uncertainty Calculations in Chemical Measurements. He is also an authorized trainer of the TrainMiC Programme supported by EU.
