• Design and screen high-affinity ssDNA aptamers targeting environmental microorganisms listed in the US Pharmacopeia.
• Develop nanoparticle-based SERS substrates (Ag/Au nanoclusters) for enhanced Raman signal detection.
• Design and fabricate microfluidic sensing interfaces for continuous monitoring of cleaning validation fluids.
• Perform sensor validation using Raman spectroscopy, microbial cultures, and cleaning validation samples.
• Develop data analysis pipelines for Raman spectral classification, potentially integrating machine learning methods.
  
  

Research & Project Responsibilities

• Plan and execute experimental workflows to achieve project milestones.
• Lead prototype development and performance optimization of the SERS biosensor system.
• Communicate research outcomes through technical reports, conference presentations, and scientific publications.
• Collaborate with industry partners and interdisciplinary research teams where applicable.
  
  

Operational Responsibilities

• Conduct risk assessments and ensure compliance with Work Safety and Health (WSH) regulations.
• Manage procurement of specialized equipment and research consumables.
  
  

Mentorship

• Mentor research engineers, graduate students, and undergraduate researchers.
• Contribute to training activities within the research group.
  
  

Others

• To communicate in any relevant internal or external stakeholders to ensure project deliverables are met.
• Any ad-hoc duties assigned by Supervisor.
  
  

Job Requirements

Essential
