πŸ‘€ About me

I am a Computational Building Scientist with a PhD in Architecture from the University of Seville (2026), an MSc in Landscape Architecture from the University of Tehran, and a strong background in computational modelling and urban microclimatology. I am currently an Associate Researcher at the IntCDC Cluster of Excellence (DFG Excellence Strategy), University of Stuttgart. I specialise in coupling high-fidelity physics-based simulation with machine learning to generate clear, actionable insights that support climate-resilient design decisions for buildings and urban systems.

My technical toolkit includes Python (PyTorch, scikit-learn, CatBoost, NumPy/pandas), multi-objective evolutionary optimization (NSGA-II/III, Optuna), and physics-based engines (EnergyPlus, ENVI-met, OpenFOAM, TRNSYS, Ladybug Tools). I build complete research pipelines β€” from climate data extraction and downscaling (CMIP6 / EURO-CORDEX, MODIS/Landsat remote sensing), through surrogate modelling, global sensitivity and causal analysis, to multi-objective optimization under future climate scenarios β€” delivered as reproducible open-source frameworks, validated simulation campaigns, and decision-support evidence for architects, engineers, and policymakers.

🧭 How I work

  • Climate non-stationarity is the design problem , I quantify where historical design baselines fail (compounded UHI–heatwave forcing, retrofit compliance risk) as computable thresholds, not narrative warnings.
  • Physics is ground truth; machine learning is the accelerator β€” surrogates are disciplined by simulation: sealed content-addressed campaigns, spatial no-leakage splits, uncertainty quantified by construction, claims validated back against the solver.
  • Reproducible or it doesn't exist , every pipeline ends in versioned, hash-sealed artifacts with deterministic multi-seed protocols; figures must regenerate from the repo.

πŸ”¬ Current research

  • Building-resolution metamodels of urban microclimate , a dual-head 3D-CNN emulating ENVI-met air and facade fields from ray-cast exposure geometry, validated against the solver's own radiative diagnostics (Szeged V-DEI); manuscript in preparation.
  • Certified design rules for PCM-integrated envelopes , sensitivity, causal discovery and symbolic regression converged into transfer-limited design rules across eight climate zones; under review.
  • Street-resolution future weather synthesis β€” EURO-CORDEX trajectories fused with heatwave detection and UHI intensification into validated 50 Γ— 50 m EPW files.
  • Longitudinal resilience of residential blocks (IntCDC, Stuttgart) β€” multi-objective optimization of energy, PV potential, and outdoor comfort across climate horizons for a representative Stuttgart district.
