Solar Radiation Testing Station & Environmental Testing
Summary:
During my internship at Gecko Robotics, I worked on a critical project to develop an in-house solar radiation testing system compliant with MIL-STD-810H standards. The objective was to expand the capabilities of our existing environmental chamber by integrating solar radiation simulation to test the durability and performance of our robotic systems, particularly for deployments in harsh environments like the UAE.

Vehicle Suspension Model Verification & Validation - Honors Thesis
Summary:
During my honors thesis, I focused on developing a systematic approach to vehicle suspension modeling, specifically targeting the verification and validation (V&V) of suspension system simulations. The project was based on a case study of an RC vehicle suspension system, where I conducted both physical drop testing and simulations using the Mississippi State Autonomous Vehicle Simulator (MAVS) platform.
Key contributions included:
Physical Testing & Data Collection: I conducted drop tests in a controlled lab environment, capturing high-speed footage of the vehicle's motion. I used image processing techniques to analyze the data, including displacement, velocity, and oscillation patterns, which enabled the identification of critical suspension parameters like spring constants and damping coefficients.
Simulation & Modeling: I implemented the identified parameters into the MAVS platform, recreating the experimental setup in a virtual environment. By simulating the drop tests, I evaluated the fidelity of the MAVS simulation compared to real-world data.
Verification & Validation (V&V): I compared the MAVS simulation results with experimental data, quantifying the differences using error metrics like Mean Squared Error (MSE). This allowed me to refine the simulation model, ensuring it accurately represented the suspension system's physical behavior.
This project highlights the importance of using real-world experimental data to validate simulation models, providing a framework for improving vehicle development processes by ensuring simulations accurately predict real-world performance
Resilience Quantification of Space Habitats
Published in International Conference of Environmental Systems
Summary:
During my work on a space habitat resilience project, I utilized the Modular Coupled Virtual Testbed (MCVT) to model and simulate the impact of various disruptive events on a habitat's power system. The project aimed to quantify the resilience of space habitats, particularly under extreme conditions such as micrometeorite collisions.
Key contributions included:
Simulation Setup: I implemented simulation scenarios within MCVT to assess the resilience of the power system. One notable scenario involved a micrometeorite impact that disrupted power converters and battery cells, allowing me to examine system recovery efforts and performance.
Network Resilience Analysis: I modeled the power system as a network comprising 13 nodes, with critical components represented as nodes and dependencies modeled as edges. I analyzed network resilience using centrality metrics such as betweenness, harmonic, and load centralities to assess the influence and importance of individual nodes.
Resilience Metrics: I computed four key resilience metrics—robustness, vulnerability, recoverability, and consolidation—based on system performance during the simulated disruptions. These metrics provided insights into the system's ability to maintain core functionality, recover from failures, and enhance stability post-disruption.
Data-Driven Results: The simulations provided critical data on system performance, allowing me to propose improvements, such as implementing redundant systems and establishing standardized protocols to minimize the impact of future disruptions.
This project emphasized the importance of network-centric approaches and performance-based analysis in improving the resilience of space habitats

Autonomous Systems Research Project
Summary:
Currently investigating the relationship between vehicle powertrain output and the roughness of various terrains. The goal of this investigation is to shed light on the impact of the terrain on fuel efficiency. The initial assumption in research related to autonomous systems that the absence of human drivers eliminates concerns about passenger discomfort. However, as the industry focuses more on fuel efficiency and sustainability, investigating the output vs roughness relationship is important.
My research employs MAVS (Mississippi State Autonomous Vehicle Simulator), a software library that enables real-time evaluation of autonomous perception and navigation software for off-road vehicles. MAVS supports high-performance computing, concurrent simulations, and physics-based sensor modeling, including LIDAR, GPS, and cameras.
