My Professional Experience
Apprenticeship as a metrologist
My apprenticeship at Evo Metrology represents the sum of my training in metrology gained through my Applied Physics studies. Beyond managing clients' instruments, I am also in charge of monitoring standard torque sensors, calculating their drift, and tracking performance over time. My work will contribute to Evo Metrology's efforts to obtain a COFRAC accreditation, a certification granted by the French Accreditation Committee (COFRAC). This accreditation ensures that the company's measurement and calibration processes meet internationally recognized standards for precision and reliability. By monitoring standard torque sensors, calculating drift, and tracking instrument performance over time, I play a key role in establishing the rigorous standards required for this certification.

Intern in Atmospheric Sciences
During my internship at the University of Wyoming I worked on the Site Aerial Basin Emissions Reconciliation (SABER) project that aimed to address the gap between top-down and bottom-up emissions accounting in the oil and natural gas industry. Top-Down accounting is done through direct measurements, whereas Bottom-Up accounting is calculated by applying component-based emissions factors to component inventory. Top-Down accounting for SABER was and still is done by utilizing drones equipped with advanced spectrometers to measure greenhouse gas emissions from oil and natural gas midstream and production facilities.
This internship focused on the development of this new drone-based quantification system and the calibration of its individual components, ensuring accurate methane, ethane, nitrous oxide and carbon dioxide quantification. The testing methodology involved stability characterization of the instruments, calibration of mass flow controllers, and assessment of GPS accuracy to enhance data precision. Key tasks included creating applications for data analysis and calibration verification, incorporating humidified calibration setups, and updating the drone's firmware to comply with new regulations.System testing demonstrated successful calibrations and enabled the development of reliable field deployment protocols for this drone-based technique. We concluded that this system has a maximum measurement uncertainty of 5% attributed to the measurement components. These results support accurate greenhouse gas emissions reporting, contributing to improved environmental accountability in the oil and natural gas sector.
