One of the most notable projects I worked on was the Pelton Wheel project. The aim was to design and engineer three different water wheels for energy generation and demonstration purposes for visitors. Alongside my college mentor, I developed a graphical user interface (GUI) to simulate the water wheel, which can be utilized by engineers worldwide

Lauren Daniels

This summer I delved into designing a simulation tool that would help small farms use water wheel technology. Alongside my work, I had the chance to unwind and explore the beautiful surroundings of Barcelona, making this summer an unforgettable experience.
