About this position
PhD opportunity at Centrum Wiskunde & Informatica (CWI), Amsterdam in inverse problems for wave-based imaging, with a strong emphasis on mathematics, partial differential equations, numerical methods, and scientific computing.
The project sits in the Computational Imaging group at CWI and focuses on developing a new mathematical and computational framework for imaging from wave measurements. The research combines PDE-based modelling with data-driven reduced-order modelling to improve robustness, computational efficiency, uncertainty quantification, and experimental design. Application areas mentioned include geophysics, medical ultrasound, and non-destructive testing.
You will investigate nonlinear inverse problems governed by wave equations, including the analysis of PDE-constrained inverse problems, properties of wave equations and their solution operators, and relaxed formulations that may reduce nonlinearity. The work begins with simpler model problems and progresses toward multidimensional acoustic and elastic wave propagation and realistic imaging applications.
The role is suitable for candidates with a Master's degree in mathematics, applied mathematics, computational science, mathematical physics, or a closely related field. Strong preparation in PDEs, inverse problems, numerical PDEs, or scientific computing is expected, along with programming experience in Python, Julia, MATLAB, C, or C++, and good English communication skills.
Funding details: full-time PhD employment with a gross monthly salary of €3,115 in year one, rising to €3,989 over four years, plus holiday allowance and year-end bonus. The initial contract is for 18 months and is extended by 30 months after positive evaluation. CWI also mentions flexible scheduling and housing support for expat employees.
Supervision is by Prof. Tristan van Leeuwen (CWI) and co-supervision by Dr. Chris Stolk (University of Amsterdam). The position is physically located at Science Park, Amsterdam, Netherlands.
Application deadline: 2026-10-31. Applicants should submit a motivation letter, CV with two referees' email addresses, transcripts, a Master's thesis copy or draft, and optionally a publication list.
