Together, we chase the miracles of science to improve people’s lives.

Main Responsibilities

• Design, develop and validate advanced in vitro ocular models for early and late-stage ophthalmic research.

• Establish differentiation protocols for induced pluripotent stem cell (IPSC) derived cell types relevant to ocular disease.

• Integrate automation and robotics to scale cell culture and differentiation workflows.

• Evaluate and implement innovative advanced ocular in vitro models (co-cultures, organoids, MPS, organ-on-chip, bioprinting).

• Apply in vitro models to study ocular disease mechanisms, validate therapeutic targets, assess multi-modality therapeutics, and evaluate safety.

• Collaborate across interdisciplinary teams in a highly matrixed research environment.

• Deliver high-quality scientific presentations and documentation to support project milestones.

• Communicate findings effectively through internal presentations and external publications.

• Provide scientific mentorship and technical guidance to junior team members.
