Key Researchers

The ISO-FOOD key researchers work at four different Jožef Stefan Institute departments from the fields of chemistry, physics and computer science.


O2Department of Environmental Sciences (DES) focuses on multidisciplinary research with emphasize on combination of physical, chemical and biological processes that influence the environment, man and human activities. The work is based on three main areas: development, optimisation and validation of analytical methods, study of geochemical processes that influence cycling and transformations of substances and elements, and environmental impact assessment which evaluates the risk that human activities present for human health and for the environment.

She has published more than 30 papers in peer-reviewed journals and more than 60 QA general and administrative procedures and reports. 


E7Computer Systems Department (CSD) is primarily concerned with the design automation of computing structures and systems. Within this broad area, it concentrates particularly on meta-heuristic optimization approaches to engineering design and logistics problems as well as electronic system design and test. CSD also performs research in advanced ICT, aimed at acquiring, storing and managing data and knowledge to be used in the development of knowledge-based applications.

 

 


Assist. Prof. Barbara Koroušić Seljak (Female, CSD) is a senior researcher, contributing expertise in heuristic optimization and software modelling, in particular of eHealth systems. She is an Executive Director of EuroFIR AISBL and a member of the Slovenian Society for Clinical Nutrition and Metabolism board of directors. 


F5Department for Condensed Matter Physics (DCMP) is focused on the study of the structure and dynamics of disordered and partially ordered condensed matter at the atomic and molecular level with special emphasis on phase transitions. The purpose of these investigations is to discover the basic laws of physics governing the behaviour of these systems, which represent the link between perfectly ordered crystals on one side and amorphous matter, soft condensed matter and living systems on the other.

 

 


Prof. Maja Remškar (Female, DCMP), PhD in physics, and one of the pioneers in the field of nanotechnology in Slovenia and in general, scientific counsellor at the JSI. She is Lecturer at Jožef Stefan International Postgraduate School and at University in Ljubljana, invited professor at Notre Dame University, Indiana, US. Research areas: one and two-dimensional crystals, inorganic nanotubes, self-ordering of nanoparticles. 


K5Department for Nanostructured Materials (DNM) focuses on research in the field of inorganic materials with specific physical properties that are a consequence of their structural and chemical phenomena at the nanostructural and atomic levels. The fields of research involve natural and manufactured ceramic materials as well as metals and intermetallic compounds. The basis of the research is to find relationships between the physical properties of a material and its structural and chemical properties by using electron microscopy techniques to reveal phenomena on the nanoscale.
