Research Interests

Current Focus
Design and development of instruments, processes, and equipment operating at low pressures (vacuum) — including vacuum gauges, gas and surface analyzers, and equipment for contaminant extraction and removal.

Main Areas

• Vacuum Metrology & Instrumentation — development of next-generation vacuum gauges (Ion trap, induced-charge detection), and provision of calibration and testing services (METROVAC).
• Gas Analysis & Leak Detection — in the context of Europe’s energy transition, development of instrumentation and protocols for CO₂, H₂, and other gases, including testing and validation methodologies for environmental emissions control.
• Vacuum Processes for Decontamination — extraction of volatile contaminants (e.g., TCA in cork) by thermal desorption under vacuum, with transfer to industrial application.

Secondary Areas

• Surface Science & Characterization — use of mass spectrometry and electron spectroscopies to characterize materials and interfaces.
• Electronics for Charge and Particle Detection — development of charge-sensitive amplifiers, data acquisition, and signal processing for scientific instrumentation.

Research Projects

European projects (ongoing or recent)

• PRESS2VAC (Horizon Europe) – Pressure and vacuum technologies for metrological traceability at intermediate pressures.
• IONGAUGE (EMPIR) – Development of a standard high-vacuum ionisation gauge.
• DECARB (Horizon Europe) – Metrology to support the energy transition and the introduction of H₂ into the European gas grid.
• MetCCUS (EMPIR) – Protocols and instrumentation for CO₂ leak detection and monitoring in CCUS (Carbon Capture, Utilisation and Storage) applications.
