Specializing in GNSS Interferometric Reflectometry (GNSS-IR) and environmental monitoring, with a focus on developing innovative solutions for sea level studies and snow depth measurements.
About Me
I am a researcher specializing in GNSS Interferometric Reflectometry (GNSS-IR) and sea level studies. Since 2018, I have been serving as a Research Assistant in the Department of Geomatic Engineering at Yildiz Technical University. Currently, I am a visiting researcher at the National Oceanography Centre Liverpool, UK, where I focus on improving GNSS-IR sea level retrievals. My expertise includes developing software tools in MATLAB and Python for data analysis, and I integrate AI models in my research to enhance GNSS-IR techniques and their applications in environmental monitoring.
Core Competencies:
- GNSS Data Processing & Analysis
- Software Development (MATLAB, Python)
- AI Model Development
- Environmental Monitoring
- Sea Level Studies
