PhD candidate in Electrical Engineering at Penn State, working on control and physical AI for robotic systems. My research is in safety-critical and adaptive control: keeping a system inside its operating limits when the dynamics are uncertain, and carrying those guarantees over to learned policies. I build the software as well as the theory, and test it on hardware.

About

Background

I am a PhD candidate in Electrical Engineering at the Pennsylvania State University, working on learned policies and control for robotic systems. Most of my current work is on generative AI for robotics: vision-language-action models, diffusion and flow-matching policies, and reinforcement learning; and on making those policies dependable enough to run on hardware, which is where safety-critical and adaptive control come in.

I work across both sides of that boundary. On the learning side: policy-gradient and model-free reinforcement learning, imitation from demonstration, and large behaviour models conditioned on language and vision. On the control side: nonlinear and optimal control, adaptive and robust design, convex optimization, model predictive control, state estimation and motion planning. These carry over to most settings where a physical system has to act under uncertainty, and I am interested in those problems broadly, not only in the robots I have used to study them.

I build the software as well as the theory. I work daily in C++, Python, MATLAB and C# with ROS and PyTorch, and I test on real hardware, including quadrupeds, manipulators, mobile bases and full-size humanoids. My earlier research was on legged locomotion and humanoid gait control.

Physical AI

Generative policies driving real hardware: vision-language-action models, diffusion and flow-matching policies, imitation from demonstration.

Reinforcement learning

Policy-gradient and model-free methods for control, tuning and sequential decision-making.

Agentic AI

Task planning and decision-making over structured world representations, executed on real systems.

Safety-critical control

Enforcing hard constraints on physical systems: barrier functions, set invariance, and safety filters around a learned or classical controller.

Adaptive & robust control

Holding performance when the model is uncertain, changing, or wrong: parameter estimation, robust synthesis, stability guarantees.

Nonlinear & optimal control

Lyapunov design, convex optimization and model predictive control for constrained, nonlinear plants.

Motion planning

Sampling-based and optimization-based planning, including MPC and MPPI, for mobile robots and manipulators.

State estimation & SLAM

Sensor fusion, Kalman filtering, and visual-inertial and LiDAR odometry for localisation and mapping.

Experience

Positions

AI Research Scientist Intern, Chewy

2026

Developing semantic safety filters for mobile manipulators driven by physical-AI policies at Chewy Robotics Lab. I use 3D scene graphs to retrieve semantic context from the environment and deploy vision-language-action models for long-horizon warehouse tasks.

Robotic Software Engineer Intern, AlphaZ

2025

Whole-body control and planning for a humanoid robot with two 6-DoF arms on a differential-drive base, plus perception and object detection. A rare chance to build robot software that combines modern learning algorithms with classical control theory.

Graduate Researcher, CARL @ Penn State

2022 – present

Control and Robotics Lab, Department of Electrical Engineering. We develop smart controllers and find formal proofs of safety and stability across a range of settings, validated on Unitree Go1 quadrupeds and Quanser QArm manipulators.

Undergraduate Research Assistant, CAST

2019 – 2022

Member of the Dynamics and Control group at the Center of Advanced Systems and Technology, working on humanoid gait. The team designed and fabricated four full-size humanoid robots; I worked on gait pattern generation and dynamic walking. See the Surena humanoid project.

Summer Intern, MEWE

2018, 2019

Two consecutive summers at an engineering consultancy in Tehran, learning drafting, mechanical design and project management.

Projects

Selected work

Research prototypes, course work and open source. Most link to a write-up or a repository.

Manipulator teleoperation from a smartphone

A phone used as a 6-DoF teleoperation device, using ARCore's visual-inertial odometry and streaming operator input to the robot controller over WebRTC and low-latency UDP. Built to make demonstration collection cheap.

Safe flow matching for vision-language-action models

A constraint embedded directly in the generative denoising process rather than applied to its output, giving SmolVLA and π-0 formal safety guarantees without retraining or safety-labelled data.

Safe parameter learning for adaptive controllers

A robust adaptive controller that shapes the parameter update so constraints hold throughout the learning transient, not only after the estimates converge.

Door opening with mobile manipulators

An MPPI planner that lets a mobile manipulator traverse varied doors across different environments, coupling base motion and arm contact in a single optimisation. Built at AlphaZ Robotics.

Safety-critical control with barrier functions

Control barrier functions applied to cases outside the standard assumptions, including recovery once the system has already left the safe set, and model-free safety-critical control of complex kinematic and kinetic systems.

Safe robust regressor-based control

A safety layer added to a standard class of robust regressor-based controllers, with an analysis of its effect on tracking performance.

Autonomous racing: MPC vs. adaptive control

Modelling and simulating a race car on a 2D track, comparing model predictive control with adaptive control on the same race line. Course project for ME597 and EE582.

Surena humanoid robot

Gait pattern generation for a full-size humanoid using the Divergent Component of Motion, with impedance control for stability over rough terrain.

Kalman filtering and system identification

A comparison of linear, extended and unscented Kalman filters for fusing sensor data to estimate the pose of a differential-drive robot. AERSP597 course project.

Wheeled biped robot

Undergraduate thesis: dynamics of wheeled-legged robots, an optimally designed simulated platform, and a control strategy that does not require the full dynamic model, including jumping.

Reinforcement learning meets classical control

PPO and actor-critic agents tuning PID gains online inside a physics engine, demonstrated on an inverted pendulum on wheels.
