With a PhD focused on hydrogen in the early Solar System, Dan pursued several postdoctoral projects dedicated to natural hydrogen, establishing himself as an expert in this emerging field. His work spans field studies across Europe and the Balkans, contributing to key discoveries and advancements in hydrogen exploration. Recognized for his expertise in hydrogen isotope analysis, he now serves as an R&D engineer at HyReveal, involved in both software and hardware development.

Among the first postdoctoral researchers worldwide dedicated to natural hydrogen.

Discovered a potential subsurface hydrogen reservoir in Kosova.

Specialist in hydrogen clumped isotope analysis.

Dan contributes to the first diamond open-access journal in geochemistry and cosmochemistry, promoting transparent, barrier-free scientific publishing.

After almost 10 years in the academia as both a scientist and an engineer, Maximilien developed a strong expertise in questioning complex and diverse data from many different domains. As so, his ability to investigate geochemical, geological and remote sensing data to unravel key aspects of hydrogen exploration brings clarity and number to back-up the decision making process.

10 years of experience exploring scientific data

5 years developing data reduction tools for CNRS

Specialized in remote-sensing, geology, geochemistry, and engineering

In a past life, Maximilien wandered the Atacama desert to collect meteorites for its PhD.

After six years in medical device development, Theo decided to return to the hydrogen domain, focusing on designing innovative and reliable electronic systems. Driven by results, he is passionate about how thermodynamics, gas dynamics, and control systems come together to build smarter, more efficient technologies.

Worked with leading companies such as Air Liquide, contributing to high-tech R&D projects.

Participated in the development of artificial hearts, miniature magnetic surgical robots, and precision perfusion pumps.

Skilled in rapid prototyping with a broad systems engineering perspective.

Theo won first prize in a Sumo robot competition, showcasing a strong combination of creativity, problem-solving, and hands-on engineering.

Fred combines the profile of a software pioneer, basin modeler, and exploration geologist. This dual background - building the tool and applying it to demanding subsurface problems - makes him a reference in translating advanced geoscience into robust exploration decisions.

30+ years of expertise in basin modeling, petroleum system analysis, and exploration geology.

Author or co-author of 100+ scientific publications on basin modeling, fluid flow, pressure, migration, petroleum systems, and natural hydrogen.

Extensive consulting experience with oil & gas operators on complex basin evaluation and exploration projects worldwide

Key contributor to the development and industrial application of Temis 3D basin-modeling technology.

Fred is a former French team champion in Chanbara - which didn't stop him from almost becoming an Orinoco crocodile's lunch.

After more than six years building full-stack web applications across medical research, e-commerce, and enterprise software, Oumaïma joined HyReveal to bring modern engineering practices to subsurface modeling. With deep expertise in React, Node.js, and cloud-native architectures, she focuses on designing performant, scalable interfaces that make complex geoscience simulations accessible to operators and decision-makers.

Contributed to an AI-assisted medical research platform classifying histological images, building both React front-end visualization with OpenLayers and Go/NestJS microservices on Kubernetes.

Six+ years of full-stack JavaScript experience across leading French tech companies including Wethenew (e-commerce) and Neoxia (R&D consultancy).

Dual expertise in modern frontend frameworks (React, Next.js, Angular, TypeScript) and cloud-native backend infrastructure (Docker, Kubernetes, GCP, AWS).

Oumaïma is passionate about traveling, discovering new cultures, meeting people, and exchanging ideas and experiences.
