Martijn Warnier

Two fully funded PhD positions are available at Delft University of Technology (TU Delft) in the area of climate risk, housing markets, mortgage portfolios, and agent-based modeling . The projects examine how physical climate hazards such as floods and drought-induced foundation damage affect property values, homeowner inequality, bank balance sheets, and broader financial stability. The first PhD, Systemic Risk in Climate-Sensitive Housing Markets , is part of the ERC SPHINX project and focuses on climate-induced flood risk in three European case studies. The work involves developing theory- and data-grounded agent-based models (ABMs) of housing markets, linking them to macroeconomic modeling, and conducting systematic sensitivity analysis. The selected candidate will be supervised by Martijn Warnier , Theodoros Chatzivasileiadis , and Tatiana Filatova . The second PhD, Strengthening Mortgage Portfolio Resilience to Physical Climate Risks , is based in the Faculty of Technology, Policy and Management and focuses on the Netherlands. It studies how climate risks propagate from homes to mortgage portfolios and how different climate-risk owners and mitigation instruments can reduce damages and inequality. This project also uses ABMs, stakeholder engagement, and a tailored homeowner survey, with collaboration across TU Delft and the financial sector. Supervisors include Theodoros Chatzivasileiadis , Zac Taylor , and Tatiana Filatova . Eligibility highlights: MSc-level background in computational science, economics, geography, spatial/environmental/financial economics, engineering & policy analysis, or a related field; strong programming skills (Python, Julia, etc.); experience with statistical/econometric analysis; ABM experience is especially important for the mortgage-resilience project; GIS/spatial modeling is an asset; fluent English required. Dutch is not obligatory. Funding: both positions are fully funded 4-year PhDs with TU Delft salary and benefits. Salary ranges from €3059 to €3881 gross per month , plus holiday allowance and end-of-year bonus. Application windows: the first PhD deadline is 2026-06-22 ; the second PhD deadline is 2026-06-28 . Applicants should apply online and submit a motivation letter, CV, and relevant publications/software outputs if applicable, plus reference contacts.
