I'm a skilled professional with a Ph.D. in Micro- and Nano-electronics, bringing together top-notch technical skills, industry know-how, and a passion for innovation in additive manufacturing. For over ten years, I've been focused on flexible printed electronics, contributing to advanced manufacturing processes in exciting ways, and implementing cutting-edge technologies in real-world applications.My work in additive manufacturing often involves the use of innovative materials, functional inks, polymers and digital printing, pushing the boundaries of what's possible in the field of Printed Electronics.Currently serving as a Senior R&D Engineer at Graphenaton Lab, I work on flexible heating films, supercapacitor systems, and printed flexible perovskite solar cells. My work involves digital printing techniques and the use of advanced materials for various applications. My previous experience includes pivotal roles at CERADROP (MGI Group) as a Product Manager and Process Engineer, where I combined my technical acumen with business strategy to drive customer acquisition, optimize processes, and ensure seamless product deployment in the field of additive manufacturing.My expertise encompasses:Additive manufacturing processes such as DOD Inkjet, Aerosol, Screenprinting and Micro-dispensing printing techniques, particularly for applications in sensors, photovoltaics, perovskites, transistors, IoT, smart sensors, photodetectors, TFTs, RFID, and wearable technologies.Bridging technical innovation with business needs, including pre-sales, customer experience, and strategic technology articulation to both business and technical users.Material engineering knowledge and advanced device fabrication skills, with a proven ability to optimize manufacturing processes for scalability.Rapid prototyping and design optimization for efficient product development.I love to identifying and solving customer issues, and my ability to serve as both a technical expert and a guide. I enjoy the creation of products that meet market demands and explaining complex technological concepts in an accessible manner, which facilitates collaboration between diverse teams and stakeholders. I'm also adept at communication and networking, which proves invaluable in project management, client relations, and guiding my teams to achieve ambitious goals.Furthermore, my specialization in "Molecular Nano- and Biophotonics" allows me to leverage working with biomaterials and applications in biomedical engineering.

Ph.D. Student In Micro-And Nano-ElectronicsIm2Np Nov 2008 - Feb 2012Marseille Area, FrancePhd subject: “Inkjet printing technology as a fabrication tool for Inorganic and Organic photovoltaic cells.”Goal: 1) to replace screen printing (serigraphic) by optimizing drop–on-demand (DOD) piezoelectric inkjet printing for front - side metallization of Si solar cells. 2) to adopt and tailor inkjet printing for patterning thin-film layers (such as PEDOT:PSS, active layers…) of organic photovoltaic cells. The following topics were the focus of my research project: - Select and choose functional inks from the market based on compatibility and performance criteria of the print-head dynamics. - Optimize printing and post-treatment parameters such as jetting parameters, drop-substrate interaction, , surface energy modification, surface patterning, drying time and curing process to achieve highly functional patterns ( such as conductive lines, low contact resistance) good adhesion, and high resolution. - Demonstrating/optimizing clear analytical characterization techniques to study the inks and the printing conditions (such as visualization of drop formation and jetting, measuring accuracy and repeatability, ink-substrate interaction characterization). - Electro-optical characterization of printed components in order to understand and measure the impact of optimized and implemented parameters (this includes infrared thermograph (IRT), Micromeasure2 surface topography, optical profilometer, mechanical profilometer, four point resistance measurement, scanning electron microscope, XDS elemental analysis, etc.).Director of the thesis: Prof. Dr. Ludovic EscoubasCo-directors: Dr. Jean-Jacques Simon, Project: PV Print project: “Development of industrial printing machine and process, for crystalline and polymeric photovoltaic panel production line”.
