Dr. Ioannis C. Vlachos is a postdoctoral researcher in the Department of Informatics at the Ionian University (Corfu, Greece), where he received his Ph.D. in 2025. He holds a Bachelor of Engineering in electrical engineering from the Technological Educational Institute of Patras (1996) and an M.Sc. in Informatics from the Ionian University (2018). His research develops low-cost, open, and field-robust Internet of Things (IoT) instrumentation for geophysical and environmental monitoring. A central strand is the design of affordable seismographs, built from geophone sensors, high-resolution ADCs, and single-board computers, validated against reference-grade stations and deployed as a continuously recording network across the Ionian islands. He also works on the stochastic and data-driven processing of the recorded signals, including deconvolution, instrument-response correction, and the separation of genuine earthquakes from anthropogenic noise. His work extends to IoT systems for landslide monitoring and to smart, camera-equipped traps for monitoring the olive fruit fly (Bactrocera oleae) using embedded machine learning. His research interests include low-cost scientific instrumentation, edge computing for environmental sensing, seismic signal acquisition and processing, and the transfer of university research into operational systems that serve local communities. His recent work appears in journals such as GeoHazards, Applied Sciences, and Measurement and Control.
