Research areas
Vertical farming & plant factories
Multi-layer, fully controlled crop production: system design, robotic handling and performance comparison of hydroponic techniques.
Plant lighting
Artificial and supplemental lighting for crops — luminaire analysis, LED spectra, PPFD / DLI planning and low-dose night lighting.
Hydroponics
Deep flow and nutrient film technique, inorganic growing media and nutrient delivery in soilless culture.
Greenhouse automation
Sensor networks, GSM / IoT monitoring, vapour-pressure-deficit control and climate management for protected cultivation.
Agricultural robotics
Robotic plant production systems, scissor-mechanism vertical farms and automation of routine crop tasks.
Precision agriculture
Sensor-based crop monitoring, image-processing data stations and decision support for field operations.
Projects
V-FARM — Vertical Farming Automation, Research & Mechanisms Lab
A hands-on lab for embedded systems, controlled-environment lighting and automation: a multi-tier growing rack under a custom 9-channel LED array, built and controlled in-house.

Four months across Europe in "Mutlu", a 1977 Volkswagen T2 camper, during an Erasmus term in Volos — the van build (solar, batteries, inverter, a DIY 12 V heated bed) and a stop-by-stop journal recovered from the Wayback Machine.
