Why You

You are working towards an upper‑class degree in a physical science such as Physics, Engineering, Mathematics, or a related discipline. You bring a solid understanding of core optical principles—including ray and wave theory—and ideally some hands‑on lab experience in optics or microscopy. You’ll thrive in an interdisciplinary environment, working at the interface of physics and biology, and you enjoy applying problem‑solving skills to real experimental challenges. Experience with simple scripting or modelling tools (MATLAB, Python, ImageJ, Labview) is valuable, alongside a collaborative mindset, strong communication skills, enthusiasm for learning, and evidence of academic achievement. Experience with breadboard optical systems or biochemical systems is a bonus but not required.

Technical & Analytical Support

• Apply basic problem‑solving approaches to define and resolve routine technical issues

• Perform experimental tasks following established procedures and standard lab practices

• Support optical system design, testing, data collection and analysis

Project Contribution

• Assist with research activities that support development of advanced optical technologies

• Execute tasks aligned to project milestones under general guidance

• Document findings, observations, and data clearly for team review

Collaboration & Communication
