Dr Atis Elsts is a senior researcher at the Institute of Electronics and Computer Science (EDI). Atis is currently leading the BCC research project (Body-Coupled Communication for Body Area Sensor Networks) and the EDI part of the PRAESIIDIUM project. He has authored and co-authored more than 40 scientific publications, and has postdoctoral research experience in Uppsala University (Sweden), RISE SICS (Sweden), and University of Bristol (UK), where he was a member of the Digital Health Engineering group. Atis is also a contributor and a maintainer of the Contiki-NG operating system for IoT, a member of IEEE, and a correspondent member of the Latvian Academy of Sciences.
Main research interests:
- Internet of Things systems and protocols, in particular the Contiki-NG OS and low-power wireless protocols
- Internet of Things applications in healthcare and other fields
- Decentralized Finance and Smart Contracts
