With my experience in CAD and measurements, I have aided in designing and testing the propulsion system of our rocket Eureka 1 (E1): our Propane-LOx Bipropellant Liquid Rocket with a final apogee of 11,000 ft and 2.7 kN of thrust. I sketched the intertank plumbing system on E1 when the setup was mainly experimentally assembled. My hands-on experience with cars has been proven to be useful in leak testing, assembly of the engine, and in machining components for the assembly of capacitance fill sensing, our Light Bulb Engine, and our main valves subsystem assembly.For our new system, Eureka 3 (E3), a Carbon Dioxide-Ethane bipropellant, system with three times the thrust power as E1 , I researched possible ablatives and their mechanical properties when E3's engine was in design and there was debate over regenerative cooling versus ablative cooling. The team's decision was to pursue regenerative cooling, and our next step was more technical designs of the injector system where I would ensure design decisions were manufacturable given our current sponsorship with ADDMAN metal 3D printing and our available campus resources. The entirety of our engine was 3D printed thanks to ADDMAN's sponsorship.Additionally, for Eureka 2 (our second iteration of Eureka 1) and Eureka 3, I have managed 20+ members interested in manufacturing using Google Sheets and prioritizing tasks by importance and time restraint. This included manufacturing all engine and structural components for E2 and post processing Engine components for the verification of E3's injector design. Managing manufacturing required that I ensure components were manufactured correctly in time for physical testing and required that I offer advice to and oversee new machinists. I also manufactured mission critical components and instructed others in their manufacturing process. I was especially skilled in documentation of manufacturing processed for future intents and purposes.

I was fortunate enough to get an offer through NASA OSTEM as a Test Engineer for an Early Career Initiative (ECI) with the team Enhancing Parachutes by Instrumenting the Canopy (EPIC) at Armstrong Flight Research Center. The goal of EPIC was to develop a strain sensor data acquisition system that could be employed on supersonic parachutes without affecting in-flight performance. In developing such a system, several strain sensors had to be validated using 1D, 2D, and then 3D strain tensors. The set of strain sensors tested included resistive and capacitive strain sensors. Of the strain sensors, capacitive strain sensors worked best as they can endure larger displacements.My role was to design the Bubble Test apparatus, an apparatus that would simulate the relevant environment and the last test before deployment in flight. The Bubble Test consisted of a pressurized vessel that would inflate to form a canopy using the test specimen (parachute fabric) and a silicone membrane to seal the vessel.

I tutored Math ranging from Arithmetic to Linear Algebra and Differential Equations. I tutored the following Physics courses: Mechanics of Solids; Fluids, Heat, and Sound; Electricity and Magnetism; Optics with Modern Physics. I also tutored C++ and MATLAB. As a tutor, I communicated complex ideas and concepts and facilitated group study sessions for students to learn critical thinking and group collaboration skills.I encountered situations where I had to understand where my students were coming from in order to better interpret their misunderstanding. I also encountered situations where I did not always know what to do, but I would research and find a solution. I loved this job as I was able to share what techniques I found helpful for learning and problem solving as well as learn from my students about different ways of thinking. It was truly an enriching experience.

I graded labs, homework, and quizzes for two sections of Electricity and Magnetism, one section of Mechanics of Solids, and one section of Optics with Modern Physics. I would communicate with the Instructor in order to calibrate understanding of the material and meet students needs during a pandemic. I had to balance the difficulty in which I graded the labs as I was fully aware of students' struggles during the pandemic. While a grader, I felt I was able to learn more about both the students' and the instructors' needs. I also encouraged students to reach out with any questions regarding the material and helped them understand the problem sets whenever possible. I feel in this way, I was really able to help students on their journey in learning the material.

During this time, I was working three jobs which posed as a challenge, but I truly enjoyed my experience working in customer service. I enjoyed working with a team of hardworking individuals in a fast paced environment. At this job I learned so much about time management and team work in completing a common goal with my coworkers and managing two other jobs. I really enjoy the fast-paced, friendly, group oriented environment that Starbucks creates among its partners and its customers. The ability to grow and advance as a partner motivated me to give them my best every single day that I could.
