## Short Curriculum Vitae

- Development of new techniques for more precise and broader material applicability luminescence dating and authenticity of archaeological, geological and paleontological materials.
- Innovative applications in the fields of archaeology and geology.
- Development of new techniques in the field of microdosimetry and environmental dosimetry applicable to luminescence dating. Recently the potentials of application of these techniques for the isotopic dating of speleothems and ancient metals are studied.
