Mirror Process Development:

• Designs and optimizes optical systems and fabrication processes using Strasbaugh polishing machines and commercial optical design software to meet rigorous performance criteria and precise dimensional requirements. Applies project management methodologies to plan, execute, and monitor mirror production activities, ensuring alignment with project objectives, timelines, and risk mitigation strategies.
• Executes fabrication of 0.8-meter O 25 mm thick (27 kg) meniscus blanks, including frequent handling and placement on 0.9-meter capacity Strasbaugh overarm grinding and polishing machines. Adjusts machine parameters-such as stroke length, rate and extension, spindle speed, and lap overhang-to achieve production of four spherical mirrors within established timelines.
• Performs optical system design validation and feasibility assessments through simulation and modeling, incorporating statistical analysis methods to evaluate system robustness and manufacturability. Develops innovative fabrication approaches for thin mirrors using prior experience and moderate knowledge.
• Drafts, refines, and standardizes technical procedures for optical fabrication, assembly, and alignment to ensure consistency, repeatability, and knowledge transfer.
• During year two, researches and evaluates the feasibility of continuous polishing techniques for next-generation spherical mirror production for LFAST.

Metrology:

• Conducts optical metrology and alignment analyses using spherometers and interferometry to characterize surface profiles and validate system performance. Captures and analyzes measurement data using established statistical methods to assess surface accuracy, predict system behavior, and ensure feasibility of design outcomes.

• Generates and maintains surface profile data within electronic databases (e.g., Excel), producing visualizations to track surface evolution throughout fabrication. Interprets interferometric data to diagnose deviations and implements corrective adjustments to machine parameters to achieve required spherical surfaces and performance specifications.

Process Documentation:

• Maintains comprehensive and accurate electronic records of machine settings, environmental conditions, tooling configurations, and process parameters to support reproducibility and continuous improvement.
• Develops and refines technical documentation, including fabrication, alignment, safe handling, and repair procedures, ensuring accessibility and standardization across the team. Identifies opportunities to improve efficiency and process reliability through ongoing evaluation of optical fabrication methods and documentation practices.

Team Lead Duties

• Provides technical guidance, task coordination, and mentorship to optical fabrication technicians, student workers, and support staff. Trains team members on fabrication processes, equipment operation, and quality standards to ensure consistency and knowledge transfer.
• Assists supervisor in assigning and monitoring daily, weekly, and monthly work, ensuring alignment with production milestones and operational goals. Fosters a collaborative work environment that supports skill development, accountability, and adherence to safety and quality standards.

Mirror Production Lab Duties:

• Collaborates with the project principal investigator, project manager, and multidisciplinary engineering teams to plan, coordinate, and execute mirror production activities. Tracks progress against milestones, presents weekly updates, and proactively identifies and mitigates risks to project timelines.
• Supports maintenance, troubleshooting, and continuous operation of specialized optical fabrication equipment and tooling. Works with engineering and scientific teams to modify or improve machines and processes as needed.
• Ensures compliance with laboratory safety standards and protocols, including proper handling of equipment and chemicals. Supports training efforts to maintain a safe and efficient production environment.

Knowledge, Skills, and Abilities

• Ability to use a large-format overarm optical polishing machines in the 36" size for making mirrors or lenses.
• Advanced knowledge of optical shop methods and practices, including glass handling, repair, surface measuring, grinding, polishing, and figuring mirrors to optical tolerances.
