Portfolio
Selected work in AI, robotics, optimization, creativity, and intelligent engineering systems
I design algorithms and engineering systems that operate under uncertainty, where assumptions are incomplete and traditional methods lose reliability. My work spans AI-driven physical systems, humanoid and autonomous robotics, geometry-aware modeling, intelligent optimization, and aerospace-relevant computation, with a consistent emphasis on robustness, interpretability, and creative system design.
This portfolio presents representative contributions, not an exhaustive record.

Intelligent Braking Systems
Treating braking as a decision-making process
Despite major advances in sensing and autonomy, vehicle braking systems remain largely reactive.
I proposed an intelligent braking framework that treats deceleration as a predictive, decision-based control problem rather than a reflexive response, with direct relevance to safety-critical and autonomous systems.
Key contributions
Control-theoretic formulation of intelligent braking
System-level decision-making architecture
Safety-critical design under uncertainty
Impact
Independently conceived intelligent braking system concept
Strong commercialization potential in a multi-billion-dollar industry
Humanoid and Embodied Robotics
Intelligence emerging through physical interaction
Many humanoid robotic systems rely on predefined stability assumptions that break during transitions, balance recovery, or real-world interaction.
My work focuses on balance, posture transitions, and motion initiation, treating intelligence as an emergent property of embodiment and interaction rather than scripted behavior.
Key contributions
Dynamics and control of humanoid systems
Balance and posture transitions under uncertainty
Embodiment-aware system design
Integration of control theory and physical interaction
Impact
Robotics research contributions
Cross-disciplinary insight connecting control, intelligence, and embodiment
NIMA: Geometry-Aware NURBS Modeling
Adaptive curve and surface refinement driven by curvature
Conventional NURBS modeling relies on uniform refinement or heuristic error measures, which often fail in regions of high curvature and geometric complexity.
I developed NIMA (NURBS Iterative Micro-move Adjuster), a geometry-aware refinement framework that adapts control points and knot placement based on curvature and stability.
Key contributions
Curvature-driven knot insertion and control-point adjustment
Stability-aware refinement rules
Robust benchmarking against IRLS, greedy, uniform, and spline-based methods
Extension from curve fitting to surface modeling
Impact
Peer-reviewed publications
Extensive numerical validation
Foundation for future geometry-aware optimization frameworks
Intelligent Optimization and PSO Variants
Robust swarm-based optimization for real engineering systems
Standard PSO methods often degrade in noisy, constrained, or ill-conditioned environments.
I designed and evaluated adaptive PSO variants with improved convergence stability, constraint handling, and robustness, tailored for real engineering problems rather than idealized benchmarks.
Key contributions
Adaptive swarm dynamics
Noise-robust objective evaluation
Constraint-aware optimization strategies
Statistical robustness analysis
Impact
Reliable optimization in complex design landscapes
Practical pipelines for engineering design and control
AI for Physical and Engineering Systems
Learning where equations alone are insufficient
Highly nonlinear and multiphysics systems often exceed the limits of purely analytical modeling.
I applied AI and physics-aware learning methods to model, predict, and interpret complex engineering data, including defect detection, fatigue assessment, and intelligent system behavior.
Key contributions
Physics-informed neural modeling
AI-assisted defect detection and prediction
Hybrid data-driven and physics-based reasoning

Creativity and Innovation
Engineering beyond optimization
Creativity is a central part of my engineering philosophy. I develop systems, algorithms, and methodologies that challenge conventional formulations and explore alternative representations when standard approaches quietly fail.

Design Philosophy
I do not design systems solely to optimize performance.
I design systems that remain reliable when assumptions fail.
Much of my work begins where existing methods appear sufficient, until they quietly break under real conditions.
Writing and Thought Leadership
I write on creativity, innovation, and future engineering systems, exploring how ideas form before proof exists and how intuition, structure, and computation interact at the edge of discovery.
