Rolands Šāvelis
Dr. sc. ing.
Researcher
Rolands Šāvelis received his PhD in Engineering from RTU in 2013, specializing in circuits and signals in electronics and telecommunications. His doctoral thesis, “Study of Signal Sampling and Reconstruction Methods”, introduced novel theories and methods for signal-dependent sampling and reconstruction.
Since 2006, Rolands has been part of the Institute of Electronics and Computer Science, where he became Head of the Signal Processing laboratory in 2023. Over the years, Rolands has contributed to a wide range of projects primarily focused on signal processing. He is the author of more than 20 scientific publications and a co-inventor of one Latvian and one European patent.
His research interests include digital signal processing, event-driven and signal-dependent sampling, signal reconstruction, spectral analysis, non-stationary signal processing, asynchronous data acquisition systems, adaptive filtering, modeling and simulation, and applications of artificial intelligence.
