Research
My research lies at the intersection of statistical data science, machine learning, and signal and image processing. I develop data-driven and uncertainty-aware methods for analysing complex sensor, imaging, and environmental data, with particular interests in probabilistic modelling, multimodal data fusion, remote sensing, and geospatial analytics. My work combines statistical inference, machine learning, and computational methods to support decision-making in real-world systems involving heterogeneous, noisy, and spatially structured data.
My research has evolved from a foundation in Bayesian signal and image processing, inverse problems, optimisation, and uncertainty quantification towards broader challenges in data-centric AI and multimodal learning. I have worked extensively on integrating satellite imagery with complementary data sources for applications including air quality modelling, crop yield prediction, environmental monitoring, and large-scale geospatial analysis. More recently, I have developed interests in uncertainty-aware machine learning, probabilistic AI, graph-based modelling, and variational inference for complex sensing and environmental systems.
Prior to joining Cardiff University, I worked in statistical computational imaging at the University of Bristol, where I conducted research on remote sensing, SAR image analysis, probabilistic imaging models, and statistical image processing. This work provided a strong foundation in imaging science and uncertainty-aware inference, which continues to inform my current research programme.

Biography
I am a Lecturer (analogous to Assistant Professor) in the School of Computer Science and Informatics at Cardiff University. I received my B.Sc. degree in electronics engineering (with Honours) from Istanbul Kültür University, Turkey, in 2009. Then, I received my M.Sc. and PhD degrees in electronics and communication engineering from the İzmir Institute of Technology (IZTECH), Turkey, in 2012 and 2018, respectively. I have been awarded the 2020 IEEE Turkey PhD. Thesis Award.
Before joining Cardiff University in 2021, I was a Postdoctoral Research Associate in the Department of Electrical and Electronic Engineering at the University of Bristol (2018–2021), where I worked on statistical signal and image processing, machine learning, and remote sensing.
At Cardiff University, I serve as Deputy Director of the Cardiff Data Science Academy (DSA), Lead of the Remote Sensing Image and Data Analysis (ReSIDA) Research Group, and Joint Programme Lead for the MSc in Data Science for Environmental Sustainability.
I have co-authored over 90 scientific publications spanning statistical data science, machine learning, signal and image processing, remote sensing, and environmental analytics. I am a member of the IEEE, the IEEE Signal Processing Society, and a Fellow of the Higher Education Academy (FHEA).
