Figen S. Oktem

Figen S. Oktem is an Associate Professor in the Department of Electrical and Electronics Engineering at Middle East Technical University (METU), Ankara, Turkey. Her research focuses on advanced imaging systems and algorithms, including computational imaging, inverse problems, and machine learning applications in signal processing.

• Ph.D., Electrical and Computer Engineering, University of Illinois at Urbana-Champaign (UIUC) (2014)
• M.S., Electrical and Electronics Engineering, Bilkent University (2009)
• B.S., Electrical and Electronics Engineering, Bilkent University (2007)

Her work bridges physics-informed machine learning and computational optics, with applications in spectral imaging, radar, and microwave systems. She has also explored Fourier phase retrieval, denoising diffusion models, and real-time MIMO radar imaging.

Recent publications highlight trends in phase retrieval using deep learning (prNet, I2I-PR, DDRM-PR), 3D MIMO imaging, and compressive spectral imaging. Techniques often integrate plug-and-play regularization, stochastic refinement, and physics-based priors.
