Where am I?
Researcher at bigQ in Copenhagen, Denmark.
I specialise in
Designing and building advanced optical setups for quantum optics research.
Developing code for controlling hardware and automating experiments.
Analysing complex data and presenting research findings through clear, high-impact writing and visually engaging graphics.
My research interests are
Quantum communication and computation
New photonic technologies
Quantum foundations
Statistical methods for physics
What have I done so far?
2025–now
bigQ, Center for Macroscopic Quantum States, Kgs. Lyngby, Denmark
Postdoctoral researcher
I lead a small team building hybrid quantum optics experiments combining single-photon sources and continuous-variable measurements.
I collaborate on developing Python tools for modelling, benchmarking, and optimising continuous-variable photonic quantum sources.
2021–2025
Quantum Optics and Information Lab, Brisbane, Australia
Doctoral researcher
My focus was on cutting-edge quantum communication research with single-photon technologies.
I designed and built complex quantum optics experiments using ultra-fast pulsed lasers, custom-engineered nonlinear SPDC crystals, motorised optomechanical systems, and superconducting nanowire photon detectors.
I also developed a Python toolbox for instrument control and data acquisition in the lab, reducing experimental setup time and fostering code collaboration within the research group.
2019–2020
HSBC, Mexico City, Mexico
Data scientist, Business Analytics team
My role helped the Compliance, Fraud, and Anti-Money Laundering teams make better decisions, turning data insights into clear actions that met regulatory needs.
I introduced new statistical methods to analyse transaction patterns and spot unusual activity and potential risks.
2016–2019
Cold Atoms and Quantum Optics Lab, IF, Mexico City, Mexico
Research associate
During my undergraduate degree, I worked on four-wave-mixing experiments in laser-cooled Rubidium-87 atoms. My main focus was building a magneto-optical trap and developing some of the software tools to support the lab’s work.
2017
National Synchrotron Light Lab, Campinas, Brazil
Research intern
Had the chance to visit Prof. Liu Lin at the Accelerator Division, working on numerically optimising the southern hemisphere’s first Synchrotron light source, UVX.
2015
University of Texas at Dallas, Texas, USA
Research intern
Worked with Prof. David Lary at UTD to explore hidden correlations between tiny airborne particles and health indicators, using machine learning on geospatial data.
