  • RASIRC (San Diego, California, United States · On-site)
    • Design Engineer II
      Apr 2025 - Present · 1 yr 4 mos

    • Test Engineer
      Jul 2023 - Apr 2025 · 1 yr 10 mos

  • UCSD Chapter - American Institute of Chemical Engineers (AIChE) (2 yrs 8 mos)
    • AIChE Board Member
      Apr 2022 - Jun 2023 · 1 yr 3 mos

      - Lead the planning and organization for a nano and chemical engineering oriented career fair. - Invited 10 companies and over 150 students to participate in the event. - Facilitated an environment where students and company representatives get to share the opportunity to network with each other.

    • Cryo-desalinisation Project (Team Member)
      Nov 2020 - May 2022 · 1 yr 7 mos

      - Created a desalination system that reduces the total dissolved solids in water from 6000 PPM to 3000 PPM through a freezing mechanism. - Designed a mixer in AutoCAD to reduce the time duration of the mixing and freezing of saltwater. - Automated the team’s desalination prototype to create a more streamlined process of making fresh water via Arduino and C.

  • Manufacturing Engineering Intern at Momentive
    Jun 2022 - Aug 2022 · 3 mos

    - Planned and executed a Design of Experiment (DOE) in root cause analysis of the varying cook times of silicone batches in their mixing stage. Formulated 3 lb batches of silicone in a lab and analyzed their cook times. - Led root cause investigation on unwanted adhesiveness of silicone strips to polyethylene sheets by reviewing operator feedback as well as QC results and production data on batch records of silicone. Culminated results in Minitab and proposed solutions to stakeholders. - Implemented an Excel calculator in production that determines the amount of time needed to cook off volatile elements to below 0.55% by mass in 4000 lb batches of silicone during its mixing stage. - Remodeled plant layouts and P&IDs in AutoCAD to be updated with recently added pieces of machinery; redrew hazardous areas as well as new emergency evacuation routes of the manufacturing floor.

  • Propulsions Team at ChemE Car at UCSD
    Nov 2019 - Mar 2020 · 5 mos

    - Collaborated with four engineers to create a car that operates through the oxidation of hydrogen gas. - Improved the delivery of the gas to the car’s fuel cell without leakage which increased the car’s travel distance by forty percent. - Communicated and arranged a work timeline to perform trial runs and collect car diagnostics. Presented findings and progress updates to faculty supervisors. - Outlined safety and operating procedures for our team’s experiments in an engineering design package document.
