Reports from the HPI Research Schools

At the 2023 HPI Research Symposium PhD students and professors from both HPI Service-Oriented Systems Engineering (SSE) and Data Science and Engineering (DSE) Research Schools will be presenting their novel research in the fields of computer graphics, human computer interaction, deep-learning, connected healthcare, Agile software development, and data engineering.

The research talks and case studies will demonstrate industrial applications of modern service-oriented systems integration, analysis of complex data using deep-learning approaches, connected healthcare applications, as well as solutions for the Big Data and IoT challenges we face in our modern world.

We look forward to sharing research among the participants of the symposium at HPI!

The HPI Research Symposium

The HPI Research Schools for "Service-Oriented Systems Engineering" (SSE) and "Data Science and Engineering" (DSE) are the two graduate schools of the Hasso Plattner Institute. The branches of the graduate schools are in Cape Town, Haifa and Nanjing. Students enjoy a great research environment and close mentorship by professors and postdocs.

The HPI Research School on Service-Oriented Systems Engineering (SSE)

The HPI SSE Research School has dedicated itself to the field of software engineering in the context of service-oriented systems. The design, analysis and implementation of service-oriented architectures poses numerous research questions from the fields of software engineering, system analysis and modeling, adaptability, and application integration.

Service-Oriented Systems Engineering represents a synthesis of best practices in object orientation, component-based development, distributed computing, and business process management, providing integration of business and IT concerns. The topics of the research school thus have a unique potential not only in terms of academic research but also in industrial applications.

The HPI Research School on Service-Oriented Systems Engineering, founded in 2005, is based on the model of the DFG (German Research Foundation) "Graduiertenkolleg". PhD students at the research school participate in joint activities such as lectures, seminars, winter schools and workshops.

The HPI Research School on Data Science and Engineering (DSE)

The 2019 newly established HPI research school on „Data Science and Engineering” unites PhD students in all areas of data-driven research and technology, including scalable storage, stream processing, data cleaning, machine learning and deep learning, text processing, data visualization and more. The participating researchers join forces whenever possible and apply their research to many different use cases across the interdisciplinary research groups.

The increasing abundance of data in science and in industry creates many challenges and opportunities. Data science has grown to be a foundational discipline in information technology, allowing new insights from data and creating ever more intelligent applications. Simultaneously, it is becoming increasingly difficult to collect, clean and deliver the vast amounts of data and apply and maintain complex data science processes. Targeting these challenges, the discipline of data engineering has become equally foundational.

The Members of the Research Schools

The professors of the HPI with their research groups are supporting pillars for the two HPI research schools. With their interdisciplinary structure, the research schools interconnect the individual research groups and foster close and fruitful collaborations.

Students enjoy an exceptional research environment, close mentorship by professors and postdocs of the research groups, interactions with their peers, enormous computing power in HPI’s data lab, and significant travel funding.
