Ergen Quantum Applications Lab is always looking for talented Master's students, Ph.D. candidates, and postdoctoral researchers. We particularly welcome applicants with backgrounds in machine learning, AI, materials science, and electrical engineering.
We develop scalable synthesis schemes, engineered platforms, and AI-augmented tools to investigate local physical properties — always a balance of fundamental science and industrial innovation.
Our program spans discovery, design, synthesis, and characterization of novel device structures — from fundamental physics to advanced engineering applications.
QUEEN platform leverages quantum super-exchange interactions to re-architect lithium-ion and next-generation batteries (Na, Mg, Ca, Li-S) from first principles, surpassing classical theoretical capacity limits.
Generating Advanced Quantum Materials for Battery Innovation and Technology. Exploits electronic tunability, strong spin-orbit coupling, and quantum coherence of B-C-N ternary phases for batteries, sensors, and broad industrial access.
Graphene, hexagonal boron nitride, MoS₂, GaN and their stacked van der Waals heterostructures for electronics, photonics, and spintronics. Defect thermodynamics and single-photon emitter engineering.
Ink-based nano-tattoo biosensors using aerogel platforms for real-time simultaneous monitoring of mechanical motion and biofluids — no external circuitry, ambient wireless backscattering. Featured in IEEE Spectrum.
Nano-engineered graphene aerogel cathodes that harvest ambient oxygen for battery charging. Demonstrated LED powering via simple air flow — foundational for EV motion-based charging concepts.
Deep learning for respiratory disease, atrial fibrillation detection, oral cancer screening from single images, and food adulteration identification — translating lab science into clinical and industrial tools.
Every project in our lab begins with a question that keeps us up at night.
EQAL actively translates research into market-ready companies, supported by European and Finnish innovation funding.
A breakthrough material that makes batteries completely fire-proof and charges them from nearly empty to almost full in minutes. The same tech keeps data centers dramatically cooler — slashing electricity costs for AI infrastructure.
Applying the Quantum Phonon Aggregation Method to produce silicon carbide faster and at lower temperatures than conventional approaches. A game-changing industrial process for semiconductor manufacturing.
Commercializing the QUEEN battery platform — quantum electron engineering to redesign energy storage chemistry from the ground up, targeting capacity and cycle life beyond today's theoretical limits.
Translating nano-tattoo sensor technology into a commercial wearable for continuous cardiac monitoring, sweat analysis, and motion tracking — batteryless, backscatter-based, printable on skin.
