The Distinguished Research Group led by Prof. Dr. Volker Markl addresses the human and technical latencies prevalent in the data analysis process. This entails simplifying the specification of data analysis programs via the automatic distribution, parallelization and hardware adaptation of data processing operations to reduce the human latency and thereby increase programmer productivity. This includes:

  • devising intelligent data processing algorithms,
  • exploiting novel advances in computer architecture (processing, network, storage),
  • building efficient data management, data science, and machine learning technologies as well as systems, to reduce the technical latency and thereby increase execution efficiency and throughput.

In Memoriam

It is with deep sadness and regret that we must acknowledge the sudden death of our former colleague and friend Jorge-Arnulfo Quiané-Ruiz. He is and will forever be sorely missed. Our thoughts and prayers are with his wife Zoi Kaoudi, his four children, and his loved ones.
