  • Coupling Game Theory with Reservoirs Models: to evaluate the coordination and utility of critical stakeholders in the CCUS and UHS value chains. At the 45th IAEE, I introduced the price of CO2 as an energy commodity, moving beyond its traditional role as a carbon tax. The framework demonstrated that a potential CCUS infrastructure in the Aphrodite Gas Field in Cyprus could generate a positive NPV for stakeholders (Emitters and O&G Producers) through coordinated efforts with limited government subsidization. The methodology is now being implemented in the CCS hub in Ravenna, Italy, operated by Eni SpA, for emitters in the region of Lombardy, Veneto, and Emilia Romagna. 3 publications are under preparation.

  • Decarbonization of a Residential House in EU: Few years ago, my family in Cyprus decided to upgrade our house in Limassol to Net-Zero. I designed the insulation and photovoltaic system and computed the investment costs. This groundwork evolved into a novel stochastic cashflow model for assessing the project's profitability. Currently, we are generalizing the model for the whole market of Cyprus, shaping the input distribution functions of this model based on behavioral economics. A conference paper was present and a publication is under preparation.

  • Modelling Energy Transition in the European Electricity and Gas System via PLEXOS: We offer consultancy services to firms interested in modeling the electricity and gas markets using PLEXOS. We are currently working with CESI and World Bank for modeling the Black Sea Electricity Project. Beyond modeling, I provide software development solutions, fully automating PLEXOS projects from input to visualization for maximizing team's productivity (Python .NET for API integration and automation).

  • Smart Contracts in Well Operations: During my MBA thesis at Eni SpA's Well Operations department, I assessed the implementation of smart contracts to automate interactions with service contractors. I translated these physical interactions into Smart Contracts using Solidity on Ethereum TestNets. The results contributed to confidential internal assessments of operating working capital, particularly in liabilities estimation, currency exchange fees, and bargaining power, and led to further company research into this technology.

  • FLINUGEE project: (Fluid Injection in Unconsolidated formations for Geo Energy and Environmental Applications - EXCELLENCE/0421/0456), funded by the Cyprus Research and Innovation Foundation.
    • Granted: €200,000
  • Mathematical and Computational Modelling of Geo-Energy Processes: We developed a screening tool using the material balance approach for carbon dioxide injection with water influx. The tool addresses two injection scenarios: depleted gas reservoirs and piston-like injection for Enhanced Gas Recovery. It is adaptable for both dry and condensate reservoirs, considering reservoir heterogeneities through stochastic petrophysical properties. Our model, inspired by Bentley et al (2017), and Ringrose (2020), offers grid-independent techniques and addresses the socio-economic challenges of CCS by position carbon dioxide as a marketable product. This work resulted in a publication (see (2)) and will be instrumental in the development of a future socio-economic model (see my work at FEEM). We are currently enhancing the model for Hydrogen Storage, introducing "pseudo-dispersion" and planning to integrate it with geomechanics simulators.

  • Field Development Strategies: During my MEng thesis at University of Cyprus, we used Petrel and MATLAB to simulate the Norwegian section of the Frigg field, leading to several innovative strategies for Field Development Plans. Our key innovations presented at AAPG Europe Regional Conference, 4th EAGE Eastern Mediterranean Workshop, and detailed by our publication in Gas Science and Engineering (see (4)), encompass the application of carbon dioxide piston-like injection for Enhanced Gas Recovery, referencing methodology from (2); a semi-stochastic algorithm for optimal double section casing design that minimizes drilling costs using real-market configurations (heuristic filter-and-sort method); a kernel algorithm assessing spatial accident risk in the field, factoring in distance and Points of Interest, from facilities to personnel; and a stochastic approach to Project Economics, accounting for uncertainties like production delays, gas price fluctuations and CAPEX and OPEX. Notably, several of these strategies have been integrated into the master’s curriculum for new students, which I am instructing.

    • Granted: €160,000
    • Achievement: Contributor to patent (USPTO)
  • Parameterization & Optimization of Predictive Physiological Based Toxicokinetic (PBTK) Models: We pioneered a predictive compartmental PBTK model to assess Nickel leaching from cardiovascular devices. We conducted in-house animal experiments, integrating the data into a time-variant system of ODEs. The system was framed within a multi-objective optimization problem, aiming to balance various physiological and device-specific parameters across the compartments (organs). Inherent to such models, data limitations and measurement uncertainties introduced a high degree of non-smoothness to the model’s objective function. Τo address this, we employed global optimization algorithms and stochastic analysis. This work resulted in three publications (see (1), (3) & (5)). We are now expanding our research to simulate the interactions in the peri-implant environment using PDEs. The current model offers valuable insights to stent manufacturers about device leachability, aiding in risk assessment and minimizing the need for additional animal testing. We are developing a platform (TOXILICO App, coming soon) to provide this service, aligning with our journey towards becoming a Hard Tech Spin-off.

  • Thermodynamic Control of Reactive Spontaneous Systems: In collaboration with my undergraduate thesis advisor, Dr. Nicos Angastiniotis, we delved into the fundamentals of materials thermodynamics. Through theoretical groundwork, MATLAB simulation studies, and hands-on experimental work, we aimed to regulate the equilibrium state of chemical reactions. Our approach focuses on adjusting the rate of change of auxiliary functions as reactions evolve. Specifically, we control the rate of change of chemical work in relation to the invoked shifts in thermal and configurational entropy by adjusting the reaction's independent variables. Before the experimental work, we simulate the attainment of the desired equilibrium state using tailor-made in-house algorithms. Our objective is the synthesis of bulk amorphous tungsten nanostructures to be used as templates for the fabrication of tungsten carbide and oxides, for industrial applications.

  • Characterization and Fabrication of Organic Nanomaterials & Electronic Devices: Experimental work was conducted centered on the dichroism properties of the oligomer CBP (4,4′-Bis(N-carbazolyl)-1,1′-biphenyl), structured around the materials science tetrahedron. Processing: I employed spin coating to deposit CBP into thin films. By varying spin coating speeds and applying thermal annealing, I influenced the film's microstructure. Structure: Post-deposition, I used optical microscopy to examine the microstructure of the films, gaining insights into their formation and arrangement. Properties: I conducted UV-Vis measurements, incorporating a polarizer to delve into the material's dichroism, a result of observed anisotropy in the structure. This allowed me to generate spectra for the films under different processing conditions. Performance: While I didn't directly test the performance of devices fabricated with CBP, I have experience fabricating and measuring the performance of devices using various organic materials like ITO/PEDOT:PSS and P3HT:PCBM. These devices, including Organic Photovoltaics (OPVs) and Organic Light Emitting Diodes (OLEDs), were created using various deposition techniques such as doctor blade, inkjet printing, and sputtering. I also employed further structural characterization tools like the profilometer and performance assessment methods like solar simulators.

Using materials like aluminum foil, activated carbon from water filters, glue, and saltwater, I fabricated various configurations of home-made supercapacitors, experimenting with carbon grinding durations, salt solutions, and glue quantities and I finally examined the nanostructure of selected electrodes through Scanning Electrode Microscopy. Concurrently, I engaged in X-ray Powder Diffraction (XRD) studies, practicing with Reference Intensity Ratio (RIR) quantitative phase analysis and Match! Software, to further explore advanced electrode configurations via techniques like Chemical Vapor Deposition (CVD).
