Introduction

Dr. Tolga Soyata joined the faculty in the Department of Computer Engineering as an Associate Professor in 2016. He comes to us from his former position at the University at Rochester, where he was an Assistant Professor-Research. His teaching interests include CMOS VLSI ASIC Design, FPGA-based High Performance Data Processing System Design, and GPU Parallel Programming. His research interests include Cyber Physical Systems, Digital Health, and GPU-based high-performance computing. 

Education

2000 PhD,  University of Rochester, Electrical and Computer Engineering

1992 MS,   Johns Hopkins University, Electrical and Computer Engineering

1988 BS,    Istanbul Technical University, Electrical and Communications Engineering

Research Interests

Dr. Soyata's  research is focused on three main areas: 1) Cyber Physical Systems, 2) Digital Health (D-Health), and 3) High-performance medical data processing and visualization. 


Cyber Physical Systems research investigates the design of near-maintenance-free, supercapacitor-based energy supply design for high-performance embedded field devices (e.g., Nvidia TEGRA3-based). A recent collaboration focuses on Cyber Physical Systems for volcano seismic activity detection and real-time earthquake and tsunami warning. The sensors that we use are either active (including a battery), or passive RFID-based. 


Digital Health (D-Health) research investigates a) RFID-based passive or battery-based active medical data acqusition circuit/system design, b) secure transportion of medical data using non-traditional encryption algorithms such as homomorphic encryption, and c) decision support for doctors using machine learning techniques such as SVMs and random forests, applied to medical data. 


High-Performance Medical Data Processing research investigates a) GPU implementation of computationally-intensive medical algorithms, b) novel visualization methodologies for medical data, especially within the cardiology field.
