Foreign visiting researchers

Dragan Popov
Faculty of Science Department of Geography
University of Novi Sad, Serbia

I received a B.S. in geography from the Belgrade University and M.SC. and Ph.D. in fluvial geomorphology from the University of Novi Sad, Serbia. I was awarded a fellowship from the Basileus Foundation in 2009 and I was invited by Dr. Dimitri Vandenberghe to do research at the prestigious Luminescence Research Group at the Laboratory of Mineralogy and Petrology (Department of Geology and Soil Science, Ghent University), where I investigated the potential of the optical dating on fluvial sands from the Tisa River Valey in Serbia.
My present project (starting May 2012) is focusing on the quaternary studies of eolian depositions in Pannonian Basin. Banat loess (Vojvodina region of Serbia) is very important in terms of the linkage between Serbian and Romanian loess sequences. In that aspect, together with Dr. Alida Timar Gabor (Babeş-Bolyai University, Cluj) and Dr. Slobodan Marković (Novi Sad University) we began our cooperation with the aim to apply a series of interdisciplinary methods (OSL dating, magnetic susceptibility and frequency dependent magnetic susceptibility, grain size analysis, and geochemistry) on loess samples from the Timiş Loess Plateau – Banat, Serbia. At the advanced and well-equipped  Laboratory of Luminescence Dating and Dosimetry of the Faculty of Environmental Science and Engineering, (Babeş-Bolyai University) I prepared in total eight samples for the comparative fine-grain and coarse grain analyzes by following the standard preparation procedure. Besides the modern facilities of the lab, the human aspects of working here is highly beneficial and incredibly friendly and motivating.

Laura del Valle Villalonga
Departament de Ciències de la Terra, Universitat de les Illes Balears, España – July 2013

I received a B.S in Geography and Geology from the University of Balearic Islands (UIB; and University National of the Sur in Argentina ( During my master studies I specialized in analysis, management and planning of coastal areas in Universitat de les Illes Balears, as well as in groundwater hydrology in the Polytechnic University of Catalonia ( In 2011 I have started my Ph.D. The objective of my thesis is to obtain a detailed description of the sedimentary records of wind origin, with special focus on the Pitiuses Pleistocene islands of Eivissa and Formentera. The interference observed between marine, eolian, alluvial and coluvial deposits constitute an important record of paleoclimatology, reflecting the past episodes that affected the Quaternary climate. Obtaining absolute chronologies in our studies is of main importance, and in order to achieve this objective we contacted Dr. Alida Timar-Gabor (Babes-Bolyai University, Cluj-Napoca)through Prof. Bogdan Onac and began our collaboration on OSL dating. Since the first moment I arrived in the Luminescence Dating and Dosimentry Laboratory of Babes-Bolyai University all the group members have been very helpful to me. I was introduced to the techniques and procedures for preparing and measuring by OSL. In only three weeks we have prepared and started dating 8 samples thanks to good laboratory facilities. Besides the scientific fruitful part of my stay, I appreciated the warmth and friendship of the entire group that made work really pleasat.

Katalin Györgyövics
Visitor student from University of Szeged, Hungary

During my exchange studies in Babes-Bolyai University in April 2011, I had the chance to visit the Luminescence Dating and Dosimetry laboratory several times. Not only could I meet the researchers and take a look at the laboratory rooms, I was very kindly offered to do some measurements on a coarse grain sample from my research area in Inner Somogy, Hungary. Revising the results from a physicist’s perspective and then doing some more tests allowed me to learn more about the luminescence properties of my samples. These data were very important for me while presenting my research in the Hungarian National Student Conference held only a few days after my visit to Cluj-Napoca.  By now, I have graduated as a geographer from the University of Szeged and currently working in Kaposvár University as a botanical and soil science laboratory assistant. I am planning to carry on my research in luminescence dating by starting a PhD thesis from September 2012 in Szeged. The experience I gained in Cluj, and also the friendship I keep maintaining with the researchers in the Luminescence lab at Babes-Bolyai University will be a great help to defend my thesis one day.
