About

I am a senior Associate Professor of Computer Science at the University of Twente, where I lead the Pervasive Systems research group. As a systems builder with over 16 years of experience, I sit at the intersection of mobile computing, Edge AI, and wireless sensing. My research objective is to bridge the gap between physical sensing and intelligent action. I lead a team of ~30 researchers working to orchestrate the full IoT stack, from capturing multimodal data on resource-constrained devices (such as earables) to processing it efficiently at the edge. Previously, I served as a faculty member at the Department of Computer Engineering at Bogazici University and Galatasaray University, and held a visiting position at USC’s Autonomous Networks Research Group (ANRG).

Research Focus

From Sensing to Intelligence: My work focuses on building context-aware, resource-efficient systems that operate in the wild. I am particularly interested in the trade-off between algorithmic complexity and energy consumption in the following areas:

• Multimodal Earables & Wearables: Moving beyond simple activity tracking to complex behavioral monitoring (e.g., cyclist safety) using ear-worn devices.
• Edge AI & Algorithmic Efficiency: Designing lightweight machine learning frameworks that can run on battery-powered devices without relying on the cloud.
• Pervasive Sensing & Connectivity: Utilizing diverse signals—from IMUs to wireless CSI—to capture rich context about human activity and well-being.
