Students for the Exploration and Development of Space: (04/2015 – 10/2016)
Recruitment Manager: (02/2016 – 10/2016)
I worked with other managers to itemize and develop positions, advertised to students, organized panel interviews, and developed a fair and organized scoring system.
I managed a total of 3 recruitment cycles, providing structure for and attending over 60 student interviews.
Of the 21 positions I helped fill as Recruitment Manager, all 21 Members stayed for the entire duration of the position they applied for.
Vulcan Rocket Recovery Systems Team Lead: (07/2015 – 05/2016)
Vulcan was a student designed sounding rocket by the UCSD chapter of SEDS that incorporated a 3D printed regenerative rocket engine. The engine, which used Lox and JP4, has been static fired 3 times, producing over 650 pounds of thrust.
I designed and directed fabrication of the parachute deployment system. The rocket was equipped with an 8’ drogue and 28’ main parachute that were designed to deploy using barometric altitude readings from our avionics PCB. I also made contributions to the Avionics Systems, including battery mounts and sled design.
I contributed major design elements to the entire rocket, including fin construction, fuel and lox tank design, engine ignition mechanism and sequence, and pneumatic disconnects for launch valves.
The Vulcan rocket successfully launched May 21st 2016.
Lander Focus Group Lead: (05/2016 – 10/2016)
Lead 4 SEDS Members that explored concepts for Vertical Takeoff and Landing vehicles that could potentially be constructed by a student team using printed rocket engines.
CAD: (Onshape, Solidworks, AutoCAD)
Designing for printability: brackets, mounts, and scaffolds for composite layups

Creating functional part spec sheets for systems
Creating Bills of Materials, Project Cost Totals
Graphing large data entries for two and three variables with proper inclusion of error bars and error propagation
Graphing standard deviation spread visualizations for part features or performance metrics
Creating documents that describe the complete fabrication process for a part, including engineering diagrams, machining tool changes, and critical dimensions to be checked for spec
