About

I’m a freshman studying mechanical engineering at the University of Tennessee, Knoxville, in the Chancellor’s Honors Program and the Cook Grand Challenge Engineering Honors Program. I previously worked at Knoxville Utilities Board in electric systems engineering, and I’m currently looking for a summer 2027 internship.

Experience

Electric Systems Engineering Intern

Knoxville Utilities Board (KUB)

Jun 2025 – Jul 2025; Dec 2025 – Jan 2026

I split my time between office design work and field inspections, roughly a third of it in the field, verifying customer complaints and confirming structure locations that GIS records couldn’t reliably provide.

Fulton High School greenway relocation

When the City of Knoxville planned a new greenway near Fulton High School, an existing utility pole on Woodland Avenue and its service line had to move to make room. I designed the pole relocation and the redesign of the adjacent service line, using PLS CADD to run finite element analysis on the affected poles. The work was reviewed and approved by a KUB engineer.

Central Magnet Academy service design

For a new sign at Central Magnet Academy, I independently developed two alternative electric service designs, one underground and one pole-mounted, iterating through several rounds of revision before final review and approval. That project also taught me a lasting lesson: after my drafts were sent back several times for small compliance issues, I went through KUB’s full specification book line by line rather than guessing. It’s fine to ask for help when you’re stuck, and sometimes the fix is slowing down, not working harder in the same direction.

I also reviewed and marked up corrections on drawings prepared by other engineers before they went out.

Created approximately 10 technical drawings and revisions to support cost estimates for utility projects in the $20,000+ range.

2D-to-3D conversion

I also converted a legacy 2D assembly drawing into a 3D model in AutoCAD 3D, enabling quick angle adjustments and eliminating repeated manual redraws for a colleague. The four views shown here (top, right, back, isometric) are that model.

Involvement

Student Space Technology Association (SSTA), JV Hypersonics Team

Fall 2026 – present

This year our JV team is designing a reusable crewed space shuttle, based heavily on Sierra Space’s Dream Chaser, that brings four crew home from low Earth orbit and lands within 20 km of its target. Reentry starts at about 7.6 km/s, around Mach 25.

I’m on the thermal sub-team. Our job is to keep the cabin’s internal surface at or below 45 °C from reentry through landing. We’re currently in the literature review stage, working toward a preliminary design review.

EF 157 Glider Design Project

Aug 2026 – present

My 5-person team is designing a mousetrap-powered glider for our engineering fundamentals class competition: a small cart, 3D printed in PLA, with a large square canopy for a wing. It launches from a 28-foot platform and has to land on a target about 18 feet away.

I led the design and aerodynamics, put together a custom flight simulator with the help of AI tools to predict where it lands, and did a lot of the team coordination. The cart now drives under its own power, and in-person testing has started.

First powered run: the mousetrap drives the cart down our test runway.
