Author Biographies

Ilze Aulika is a solid-state physicist (PhD from the University of Latvia, UL, in 2008) with a diverse background in research and industry, with expertise in experimental physics, material science, and thin-film technologies. She is one of the ToF based optical tactile sensor inventors and underpinned the Sestosenso project (GA number 101070310) to achieve this concept jointly with ISL, UZ, and UL. Currently, her research is focused on Sestosenso project coordination at the Institute of Solid State Physics, UL, in situ optical investigations of thin films/multilayers for smart windows and OLEDs (e.g., optical gradient, interphase, surface modifications during UV irradiation, temperature and electrical cycles), IR light interaction with the matter for ToF advanced applications.
Patricija Paulsone received her master's degree in natural sciences from the University of Latvia in 2022 and is now pursuing doctoral degree in natural sciences. She works as a scientific assistant at Laboratory of Organic Materials in Institute of Solid-State Physics, University of Latvia. The main research area is investigation of organic luminophores and their optical properties for application in organic solid-state lasers and organic light-emitting diodes.
Dr. Sven Oras is a researcher of nanomanipulations in the Institute of Technology, University of Tartu. He obtained his MSc in Physics (2014) from the University of Tartu and a PhD in Materials Chemistry (2018) from the University of Upper-Alsace focusing on the tribological properties of systems containing metal nanostructures. Currently, he is working on studying diffusion of metal nanostructures in elevated temperatures. His work in the study of nanostructures has resulted in 28 publications. Dr. Oras is also an active lecturer on courses in Applied physics, Electronics, Telecommunications, Metrology and Metals.
