About me

I am a mechanical engineer with over 10 years of experience in the field of energy efficiency of buildings. My expertise includes a strong background in building physics, HVAC systems, and thermal systems.

In addition to my expertise in energy modeling and simulation (TRNSYS, Open Studio, Carrier HAP, THERM, EES, PEB), I am also interested in data science, machine learning, and deep learning applications.

I began my career in 2010 at the Thermodynamics Laboratory of the University of Liège in Belgium where I participated in several research projects: Bricker, iSERV, IEA EBC Annex 53.

Later, I joined the engineering consultancy firm Sweco Belgium where I applied energy efficiency principles to projects involving energy audits, green building certifications (BREEAM), energy performance certifications (PEB Belgium), and HVAC system design.

Currently, I am seeking new challenges and opportunities to advance my career. I am convinced that data science and machine learning can provide innovative and effective ways to improve the energy efficiency of buildings and other industries.

If you would like to learn more about me, please feel free to download my resume, check out my social media profiles, or contact me directly via email. I would be happy to hear from you and learn more about your interests and projects.

Software skills

During my entire professional career I have extensively used modeling, simulation and programming tools.

Building energy modeling


TRNSYS is a simulation program commonly used in the fields of building simulation and renewable energy engineering: solar thermal processes, ground coupled heat transfer, wind and photovoltaic systems, among others.

Open Studio

OpenStudio is a collection of software tools to support whole building energy modeling using EnergyPlus and advanced daylight analysis using Radiance.


EnergyPlus is a whole building energy simulation program used to model both energy consumption for heating, cooling, ventilation, lighting and plug and process loads and water use in buildings.


THERM is a state-of-the-art computer program based on the finite-element method and used to model two-dimensional heat-transfer effects in building components such as windows, walls, foundations, roofs, doors and other products where thermal bridges are of concern.

PEB (Belgium)

The PEB software is the official calculation tool provided by the Belgian energy performance of buildings program and used (among others things) to verify compliance of the requirements for each particular project.

Data analysis & machine learning


Python is a free, open-source programming language which has a huge and growing ecosystem with a variety of open-source packages and libraries.

Some of them are: Numpy, Pandas, CoolProp, pvlib.


MATLAB is a high-performance language for technical computing which allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages.

GNU Octave

GNU Octave is a high-level language, primarily intended for numerical computations. Octave helps in solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with MATLAB.
