About

I am a quantitative researcher and startup founder working at the intersection of applied mathematics, scientific computing, and artificial intelligence. I build mathematical models and computational systems that make complex, high-dimensional problems tractable, uncertainty-aware, and usable in practice.

I earned my PhD in Applied Mathematics and Computational Sciences from KAUST, and I hold a BSc in Physics with a minor in Mathematics from the University of Washington, Seattle. My research focuses on computational methods for parametric systems, especially surrogate modeling, probabilistic inference, adaptive sampling, eigensolution tracking, and low-rank (tensor-train) representations.

Increasingly, my focus is on turning rigorous ideas into real products. Through LandSense, I am building an intelligence platform for Saudi real estate brokers in a market where transaction, geospatial, and regulatory signals are fragmented across disconnected systems and workflows. The goal is to stitch those signals into coherent, reliable, uncertainty-aware, and explainable tools for portfolio strategy and off-market opportunity discovery.

Startups

Founder, LandSense Visit →

  • Founded and led LandSense, a Saudi proptech startup building an intelligence layer for brokers across valuation, portfolio strategy, and off-market deal sourcing.
  • Turned fragmented transaction, government, and geospatial data into a decision platform that helps brokers price assets more intelligently, focus sales effort, and identify high-potential opportunities.
  • Built the company's core valuation and decision engine, combining statistical pricing models, comparable analysis, confidence signals, and explainable outputs into practical pricing guidance.
  • Developed an agentic AI layer for broker workflows, with tool-connected AI agents that gather market evidence, generate bilingual reports, and support strategy and client-facing conversations.
  • Built the product stack end to end, from data ingestion and geocoding through APIs, reporting, and production deployment on AWS.

Research Areas

Key areas spanning probabilistic modeling, data compression, and computational methods.

01

Probabilistic Modeling & Machine Learning

Building models that know what they don't know - using Gaussian processes and kernel methods for prediction with calibrated uncertainty.

Kernel functions serve as the common thread connecting Gaussian processes, state-space models, and neural network approximations. The focus is on making inference scale to large problems while keeping predictions well-calibrated, robust, and interpretable.

02

Data Compression with Tensor Trains

Squeezing large mathematical objects into compact representations that scale to high dimensions.

Tensor-train decompositions break high-dimensional data into chains of small matrices, keeping costs manageable even as the number of dimensions grows. These compact representations can stand in for full simulation models or large covariance structures, enabling faster computation without sacrificing accuracy.

03

Computational Methods for Parametric Models

Making complex simulations cheaper by building small, certified surrogate models that adapt to the problem's structure.

When a simulation depends on many parameters, running it for every combination is impractical. Adaptive sampling and reduced-order techniques build lightweight stand-ins that come with accuracy guarantees, making it feasible to explore large design spaces and track how solutions change across parameters.

Current Directions

Active lines of work connecting the research areas above.

Tensor-Train Surrogates Meet Machine Learning

Combining tensor-train decomposition with neural networks and Gaussian processes to build hybrid surrogates that scale to high-dimensional parameter spaces. The tensor-train format provides structure and compression, while ML components handle the nonlinearities and uncertainty that arise in complex simulations.

Learning-Informed Greedy Methods

Extending certified greedy algorithms with data-driven parameter selection and ML-based classification of eigensolutions. The goal is to let the algorithm learn where to sample next, rather than relying on exhaustive sweeps, making reduced-order modeling practical in higher dimensions.

Symmetry Detection in Evolution Equations

Building symbolic algorithms for the automated detection of discrete symmetries in evolution equations - going beyond classical Lie symmetry methods to uncover structure that can simplify analysis and reduce computational cost.
