MS Applied Mathematics researcher at NED University of Engineering & Technology, Karachi, supervised by Dr. Fahim Raees. I develop physics-informed neural networks and neural operators for solving partial differential equations, with applications to interface-tracking problems in computational fluid dynamics and thermal analysis of building materials.
Seeking fully-funded PhD positions for Spring 2027
My research focuses on integrating deep learning with classical numerical methods for solving partial differential equations. Specifically, I study how physics-informed neural networks can be designed and trained to accurately capture evolving interfaces governed by the level-set advection equation—a problem central to computational fluid dynamics. I am interested in understanding and improving PINN training dynamics through architecture design, loss balancing, and regularization strategies, and I aim to extend these ideas to neural operator frameworks for broader PDE applications.
Training strategies, loss balancing, causal weighting, and architectures (RFF, modified MLPs) for accurate PDE solutions.

Numerical methods for PDEs, optimization, and gradient-based methods for scientific applications.
Physics-informed neural operators for thermal analysis of building materials in hot-dry climates, with applications to climate-resilient construction.

A 69-experiment ablation study of PINNs for the level-set advection equation across four benchmarks: linear translation, solid-body rotation, reversed vortex deformation, and the Zalesak rotating slotted disc. Key findings include an 82× error reduction via eikonal weight tuning, a novel RFF–eikonal joint design constraint, and state-of-the-art results on RV (T=8, 0.63%) and ZD (0.13%), outperforming PirateNet (Mullins et al., 2025) using a standard tanh network.

A two-stage framework combining a Crank–Nicolson FDM solver under diurnal solar forcing and a PINO/FNO surrogate for parametric thermal analysis of five indigenous Sindh wall materials across a nine-dimensional parameter space (1500 LHS samples). The trained PINO attains a 0.201 K MAE on peak inner-surface temperature while preserving the FDM material ranking exactly; trained on 150 samples it matches a data-only FNO trained on 300, and it reproduces the ISO 13786 time lag and decrement factor to 0.99 h and 0.010.

Thesis: A Systematic Study of Physics-Informed Neural Networks for the Level-Set Interface Advection
Supervisor: Dr. Fahim Raees
Developed a PINN framework for the level-set advection equation and conducted a systematic 69-experiment study across four benchmark problems, identifying a novel RFF–eikonal joint design constraint that achieves an 82× error reduction.
