Caribbean Industrial Research Institute
01.2024 - Current
- Conduct comprehensive mechanical and analytical testing of construction materials in compliance with ASTM and ISO standards. Apply appropriate test methods to evaluate properties such as strength, durability, and material composition to support product certification and quality assurance.
- Perform mechanical and analytical testing on welded specimens following API, AWS, and ASME standards. Evaluate weld integrity, detect defects, and assess weld performance to ensure compliance with industry requirements and safety standards.
- Develop, validate, and implement innovative test methods tailored to the specific requirements of local utility companies. Work closely with stakeholders to assess existing standards, identify performance gaps, and recommend enhancements to testing procedures. Continuously review and improve testing protocols to align with emerging industry best practices and regulatory standards, ensuring reliability and safety of utility infrastructure components.
- Operate and interpret analytical results from FTIR (Fourier Transform Infrared Spectroscopy) to identify polymers, detect contamination, and verify material compositions. Prepare samples carefully to obtain high-quality spectra, and collaborate with engineering teams to apply findings toward product development and failure prevention.
- Perform elemental and chemical composition analysis using a Carbon Sulphur Determinator. Accurately quantify carbon and sulfur levels in metallic samples, contributing essential data for material certification, metallurgical evaluation, and compliance with industry specifications.
- Utilize XRF (X-ray Fluorescence) technology for rapid, non-destructive elemental analysis of metals, coatings, and composite materials. Interpret spectral data to support quality control, material verification, and investigative testing in accordance with client and regulatory requirements.
- Conduct XRD (X-ray Diffraction) analysis to identify crystalline phases, assess microstructural characteristics, and detect material anomalies. Apply XRD data to support root cause investigations, material verification, and research projects aimed at improving material performance.
- Employ SEM (Scanning Electron Microscopy) for high-resolution examination of surface morphology, microstructure, and fracture surfaces. Prepare specimens and optimize imaging conditions to reveal defects, corrosion, and failure modes. Collaborate with metallurgists and engineers to analyze macrographs and provide insights into material behavior and failure mechanisms.
- Lead Failure Analysis Investigations and Root Cause Analysis to diagnose material or process-related issues. Coordinate with cross-functional teams to gather data, identify causes of defects or failures, and recommend corrective actions to improve product quality and prevent recurrence.
- Perform calibration of soil testing apparatus and compression machines used for concrete testing following appropriate standards. Collect, analyze, and interpret calibration and test data using statistical methods and graphical presentations such as control charts and trend graphs. Prepare detailed technical reports incorporating these visual data representations to clearly communicate findings, ensure equipment accuracy, and support decision-making for maintenance and quality assurance.
- Participate in continuous improvement initiatives to optimize testing protocols and reduce turnaround times without compromising accuracy.
- Provide technical guidance and training to junior technicians to ensure adherence to testing standards and safety protocols.
- Support internal and external laboratory audits, ensuring compliance with ISO/IEC 17025 and other accreditation requirements.
- Analyze test data and generate detailed technical reports for internal stakeholders and clients.
- Ensure accurate calibration, maintenance, and operation of laboratory equipment to maintain high testing standards.
- Collaborate with engineers and technicians on complex testing programs, non-conformance evaluations, and continuous improvement initiatives.
- Enforce strict adherence to laboratory safety protocols, quality procedures, and documentation standards.
