Improving Laser Speckle Imaging Technology
, 2022 I work at the Institute for Computer Science and Control (SZTAKI), where my research group recently started to explore the field of laser speckle imaging with a focus on improving Laser Speckle Contrast Imaging (LSCI). The method is based on the laser speckle phenomenon, which is in fact the interference pattern of backscattered coherent light.

Advanced Functional Materials, EarlyView.Self‐assembled monolayers (SAMs) are promising hole‐transporting materials for organic photovoltaics (OPVs), but suffer from self‐aggregation and poor large‐area uniformity. We find that interfacial modification using nicotinic hydrazide can eliminate the residual SAM aggregates by forming energetically favorable complexes, yielding uniform SAM.

Metachromatic Butterfly Bile Pigments for Multi‐Level Optical Security Films
Advanced Functional Materials, EarlyView.Bio‐derived optical security materials are manufactured by embedding butterfly‐based pigments in polymer films. Tunable color and fluorescence responses arise from concentration‐controlled metachromasy, enabling spatially encoded patterns with distinct visible, UV‐active, and spectral signatures.
