Hello, I'm Hunter Ellis.

I am an Electrical & Computer Engineer with interests in control systems and signal processing.

Currently working on my Master's Thesis under the advisory of Dr.Thinh Doan and Dr.Michael Hsiao.

Experience
2024 – Present
Currrently, I am working on my Master's thesis in multi-task reinforcement learning for robotics applications.

2024

I worked at NASA's Marshall Space Flight Center with the Jacobs Space Exploration Group as a Thrust Vector Control Intern, developing the active hardware and software components of their new Active Inertial Load Simulator for the Mars Ascent Vehicle.

Hardware elements that I aided in the integration of included measurement equipment such as an LVDT and full-bridge pancake load cell and test equipment such as an industrial electromechanical actuator (EMA), which entailed characterization testing and modeling of the physial characteristics of the actuator.

The software that I developed included a high fidelity non-linear physcial model of the EMA and generalized software tools used to test EMAs.

In this video you can see the characterized EMA in the closed-loop system being used to model the dynamics of a mass-spring-damper!
2020 – 2024
Bachelor of Science at Virginia Tech with a double major in Computer Engineering and Electrical Engineering (with focuses in Machine Learning and Controls, Robotics & Autonomy, respectively).

During my undergraduate studies I also worked on two design teams: Solar Car and Human Powered Submarine. For Solar Car I worked with Leads to develop the overall E/E architecture of the car and designs for the car's lithium-ion battery. For the Human Powered Submarine I used a single board computer to develop a GUI for the submarine pilot, aiding them in navigating and guiding the submarine.

I also participated in undegraduate research with Professors Thinh Doan and Michael Hsiao, developing symbolic reinforcement learning architectures to play atari games.
2023
I was a Research Intern at the Grenoble Electrical Engineering Laboratory (G2ELab) in Grenoble, France, working on inverter control systems for "microgrids" – small power grid systems aiming to avoid future infastructure problems on the French power grid.

I also had the opportunity to witness lots of the research happening at the European Synchotron Radiation Facility (ESRF) and the Institut Laue-Langevin (ILL).
2022
I was a Concept Research Intern at the Center for Innovation in Ship Design (CISD), working on the Hospital "Sea-Train" concept.

Better Notes
Recently, I have begun taking notes in LaTeX. I started doing this so that I can have notes that don't just last the lifetime of the course. Here are some of my Control Systems notes I took in grad school.
