## Contributions
Christos Karras has contributed to the field of computer science through research focused on the integration of cloud services and the analysis of real-time data. In 2020, he developed an "IoT Based Home Automation System using a Cloud server and Amazon Dot," which explored the practical application of voice-controlled cloud interfaces in domestic environments. 

Following this, in 2022, he published research titled "Design and implementation of a system for recognizing patterns and unique events in IoT data streams." This work addressed the technical requirements for identifying significant occurrences within the continuous flow of information generated by IoT sensors. His current doctoral research at the University of Patras, conducted under the supervision of Spyros Sioutas, extends into decentralized systems and deep learning. Karras has also worked on sampling methods and Markov chain Monte Carlo (MCMC) simulations. His technical expertise is further validated by an IBM Data Science Professional Certificate.
