Scientific project officer, Energy Expert

European Commission, Joint Research Centre

I am an engineer working in the science and policy interface with a broad knowledge in energy technologies. My research interests include energy system analysis, process analysis and design, and data science application. I have demonstrated my strong analytical, modelling and problem-solving capabilities in numerous scientific publications and development of scientific software. I am a pleasant and open person to work with. I enjoy following the latest technological developments and how they are affecting the world we live in.

Scientific software

Below you can find a list of scientific softwares that I have developed or contributed during my professional career.



enlopy is an open source python library with methods to generate, process, analyze, and plot energy related timeseries. While it can be used for any kind of data it has a strong focus on those that are related with energy i.


DEEP can be used for performance and cost evaluation of various power and seawater desalination co-generation configurations. DEEP is suitable for comparison analysis among different plant types (steam, gas, combined cycle and heat only plants), different fuels (nuclear, oil, coal) and various desalination options including Multi-Effect Distillation (MED), Multi-Stage Flash (MSF), Reverse Osmosis (RO) and hybrid options.


DE-TOP can be used to models the steam power cycle (Rankine cycle) of different water cooled reactors or fossil plants, and the coupling with any other non-electrical application such as desalination and district heating.


The Dispa-SET model is an open-source unit commitment and optimal dispatch model developed at the JRC. It focuses on the balancing and flexibility problems in the European power system. It is written in GAMS with advanced input/output data handling and visualization routines in Python.


WAMP can be used for the estimation of water needs in power plants especially for water cooled nuclear power plants. The program estimates both the needs for cooling water and other essential systems.
