Barbara Stawarz-Graczyk

Barbara Stawarz-Graczyk is an Assistant Professor at the Department of Metrology and Optoelectronics within the Faculty of Electronics Telecommunications and Informatics at Gdańsk University of Technology. Her research spans semiconductor device characterization, optical metrology, and biomedical applications.

Her primary research interests focus on semiconductor noise analysis, particularly Random Telegraph Signal (RTS) noise in optoelectronic devices and silicon carbide components. She has developed specialized measurement systems for analyzing low-frequency noise in optocouplers (transoptors), Schottky diodes, and MESFET transistors. More recently, her work has expanded into diffraction phase microscopy applications for observing red blood cell fluctuations, demonstrating interdisciplinary movement into biomedical diagnostics.

Analysis of her 29 publications from 2004-2018 reveals a strong technical trajectory from fundamental semiconductor noise characterization toward biomedical applications. Her early work (2004-2010) concentrated on RTS noise identification methods, optocoupler characterization, and measurement system development. From 2015 onward, she transitioned to applying similar measurement principles to biological systems, particularly using diffraction phase microscopy for hematology diagnostics.

She has been involved in developing specialized measurement systems including:

• RTS noise identification systems for optocouplers
• Wide current range measurement systems for power diodes
• Specialized probes for optoelectronic noise measurement
• Phase object observation systems using diffraction microscopy

Her research demonstrates consistent focus on precise measurement techniques with applications spanning semiconductor technology, metrology, and biomedical diagnostics, showing evolution from pure electronics toward interdisciplinary biomedical engineering applications.
