Development Driver for Excalibur: • Qualitatively reported the performance regimes of the vehicle (mainly steering and handling, and brakes) during our testing days • Provided design feedback to the Electrical + Steering Wheel subteam on the vehicle's HMI + Regenerative Braking system after significant testing time to reduce driver workload during long testing stints or race events, while maximizing driver effectiveness(efficient and strategic driving)• Provided Ergonomic feedback for the vehicle seat in order to minimize driver fatigue and allow for better driver comfortRacing Excalibur: • One of four solar drivers during the Formula Sun Grand Prix in 2024 at the National Corvette Museum Park track• Fastest lap(4 minutes, 21.424 seconds) for the SOV class (and of the race) with an average speed of 43.4 mph and peak of over 60 mph during its inaugural race

Berkeley, California, United States

Summary: Improve process workflows for mechanical subteams, starting with the iterations of Excalibur and the next Gen11 vehicle. Also, worked on closing out various systems on Excalibur. Details:• Led the decision to switch to 3DExperience for CalSol's PDM as GrabCAD Workbench was ending in 2023. • Created process documents for new incoming members to quickly learn the CAD and analysis tools available to the team.Technical tasks: • Kevlar layups on cured carbon fiber layups to meet new regulations • Manufactured tie-rods using a lathe for the battery team• Carbon fiber repairs on Excalibur's occupant cell due to heat damage from past welding • Modified/Repaired composite panels for rollcage mounting onto the occupant cell

University Of California, Berkeley

Summary: Ran analysis studies of suspension using hand-calc FBD analysis, SolidWorks FEA, created tuning/design requirements using spreadsheets, and designed brackets for the Excalibur re-design phase after a change in regulations for ride-height. Details:• Proposed and designed a system for testing, then tested Excalibur's CoM location by using hand-calc FBD analysis, ramps, and scales to determine the limits of Excalibur's static stability. • Calculated the motion and stresses on the rod-ends of the front suspension on Excalibur using FBD analysis, and generated a Matlab script to calculate the max stresses while varying the suspension parameters. • Created spreadsheet calculators to determine the required shock absorbers and springs to achieve the desired response, ride-height, lateral/longitudinal stability in dynamics, and roll-over stability. • Designed front suspension shock-mounts brackets for Excalibur during the re-design phase using SolidWorks CAD and FEA.

Austin, Texas, United States

Summary: Operations review from manufacturing/factory side to ensure that the final-product from the new program is manufacturable, can hit quality/yield targets, avoids potential production pitfalls, and ramps without issue. • Analyzed all part systems using CATIA V5/V6 and ongoing changes within General Assembly using 3DExperience for the new program. • Coordinated meetings to ensure that Process and Manufacturing teams were able to determine the best path forward on potential designs. • Reduced BOM variant complexities on LV Harnesses, IP, and other subsystems by finding methods to commonize parts, and drive BOM cost reduction and Process/Quality improvement before SoP. • Prevented "x" amount of seconds of cycle-time and eliminated 1 head-count for harness install by pushing Process teams to re-evaluate a factory-specific design.• Used JIRA system to create tickets, raise P1 issues, and track tasks to completion related to job scope.

Austin, Texas, United States

Summary: Introduced new products to the production line as the commodity owner of Center Console, Headliners, and Instrument Panel on Model Y at GFTX.Details:• Initiated meetings with stakeholders to coordinate incoming changes to the production line and signed-off on appropriate Change Actions(CA)'s.• Ran lineside trials at the factory in support of design / supplier changes with minimal downtime and relayed any feedback from the trial to design engineers, supplier/supplier-relations team, and other stakeholders. • Successfully completed multi-part coordinated cutovers on the production line several times in support of program launches. • Balanced the MBOM for multi-sourced components based off inputs from Production, Warehouse team, Material Planning, and other stakeholders. Additionally, supported large-scale cutovers for coordinated product changes or for program launches.

• Compiled propulsion anomaly reports from Space Shuttle program for failure history analysis, leading to a published conference paper: “Trends in Human Spaceflight: Analysis of Observed Propulsion Failure Modes Following NASA’s Artemis I Mission”• Generated short heritage reports and analyzed propulsion component design differences between Shuttle and the European Service Module(ESM), the in-space propulsion unit for Orion • Updated internal database spreadsheet for component data • Supported review of verification documents for Qualification Review• Generated 1-page summaries for Variances and presented them to the S&MA management• Peer-Group Leader for 7 other interns; providing resources to other interns during the virtual internship session and bringing in speakers for us• Completed STEP(S&MA(Safety & Mission Assurance) Technical Excellence Program) Level 1 course

Mercury Red Team Member - 1st place winners•Designed and presented a lunar exploration rover concept using Autodesk Inventor•Researched and compiled the different options for mechanical subsystems and scientific instruments, and compiled a list of their effects on integration and mission success•Generated a Mission Design Log using Google Sheets to track monetary, mass, and power budgets, and schedule while optimizing for a maximum science return potential. •Created team collages with our photos during our virtual meetings for bonus points during the competitionBackground: A workforce engagement program targeted towards community college students to gain valuable skills in engineering, team management, and science, while also learning about NASA's missions and their various roles in the aerospace industry. After the online training portion, students are grouped into teams to design their own exploration mission to the moon and are judged on mission success criteria, presentation skills, and team etiquette.

•Designed various mechanical systems for the Mars lander concept, including EDL(Entry, Descent, and Landing) subsystems and instruments using Siemens NX and Autodesk Inventor•Researched different methods of Mars orbit insertion and atmospheric entry, and presented them during team meetings•Documented/wrote various engineering and science sections within the PDR(Preliminary Design Review) for design and mission justification, mainly the Manufacturing and Testing Plans, and the Science Payload Validation and Verification Plans.A 12-week Student Professional Workforce Development Program that models NASA's process in developing mission concepts.
