I am and have been involved in several funded research projects in areas such as big data systems, scientific workflows, stream processing, distributed IoT systems, smart city applications, and software development tools.
News - 2023 / 2024: After recently joining the School of Computing Science at the University of Glasgow and submitting my first individual proposal to EPSRC, I am looking for collaborators to co-develop new research. If you are interested in collaborating, please get in touch (lauritz.thamsen at glasgow.ac.uk).
I am currently involved in the following funded research projects, which I also helped to put forward:
C5: Collaborative and Cross-Context Cluster Configuration for Distributed Data-Parallel Processing (2023-2026, funded by the German Research Foundation - DFG)
Aim: Sharing of runtime information (such as job runtimes, resource usage, and application events) across different execution contexts (such as particular cluster resources) presents a significant opportunity for performance modeling and adaptive resource management, allowing resource allocation for large-scale distributed computing jobs to be tuned even when the availability of context-specific runtime data is limited. Therefore, this research project aims to develop new methods for cross-context cluster configuration optimization based on shared performance data and models.
Involvement: I am involved as a researcher co-investigator, working closely with the project's RA and student assistant to develop new collaborative methods for reusing performance data and models across execution contexts for efficient distributed data processing.
Consortium: The research project is an individual project in Prof. Odej Kao's Distributed and Operating Systems group at Technische Universität Berlin with me as a partner at the University of Glasgow, having moved to Glasgow after the submission of the project proposal.

FONDA: Foundations of Workflows for Large-Scale Scientific Data Analysis (2020-2024, funded by the German Research Foundation - DFG)
Aim: The Collaborative Research Center FONDA (SFB 1404) investigates methods for a more productive development, execution, and maintenance of data analysis workflows for large scientific data sets. The long-term goal is to develop methods and tools to achieve substantial reductions in the development time and development costs of Data Analysis Workflows. Towards this goal, the project aims at finding new abstractions, models, and algorithms that can eventually form the basis of a new class of future data analysis workflow infrastructures.
Involvement: I am part of a subproject on "Scheduling and Adaptive Execution of Data Analysis Workflows across Heterogeneous Infrastructures" (between the groups of Prof. Odej Kao at TU Berlin and Prof. Henning Meyerhenke at HU Berlin). I am further part of the Thesis Advisory Committee of three PhD students (primarily supervised by Prof. Ulf Leser at HU Berlin and Prof. Odej Kao at TU Berlin). I was also a guest professor in the Department of Computer Science at HU Berlin, substituting for Prof. Ulf Leser in the context of the project in the winter semester of 2021/2022.
Consortium: The project involves 19 research groups from eight research organizations, mostly located in Berlin and Brandenburg. It is coordinated by Humboldt-Universität zu Berlin and includes Technische Universität Berlin, Freie Universität Berlin, Universität Potsdam, Zuse-Institut Berlin, Heinrich-Hertz-Institut Berlin, and Charité – Berlin University of Medicine, among other institutions.

OPTIMA: Data Integration for Predictive Control and Operational Optimization of Pumps in Wastewater Systems (2019-2022, funded by the European Regional Development Fund - ERDF)
Aim: The goal of the joint project was to integrate data from various sources (distributed sensors, weather forecasts, historic operational data) to operate wastewater pumps energy-efficiently in normal operation and reduce sewage overflow volumes in extraordinary heavy-load events. For this, the project developed a predictive control system for wastewater pumps that anticipates loads and learns pump-specific behavior.
Involvement: I led a subproject with an RA and a student assistant on data integration and platform development, providing a central reliable system between sensors, forecasting components, and the pump control system. This central data analysis platform was made up of scalable and reliable messaging, stream processing, and data management systems.

WaterGridSense: Condition Monitoring and Prognosis in Water and Wastewater Networks Using Distributed Sensors (2018-2021, funded by the German Federal Ministry of Education and Research - BMBF)
Aim: The project developed a small, self-sufficient, and configurable sensor platform for use in rainwater and wastewater systems. The sensor platform connected wirelessly to LoRaWAN gateways and provided time series data on the condition of the wastewater network. Using scalable reliable systems, the sensor data was aggregated and analyzed to present status information in a utility's operations and maintenance platform.
Involvement: I led a subproject on "Sensor Data Analysis (Platform, Status Monitoring, and Prediction)" with two RAs and student assistants, developing a novel sensor streaming data analysis platform and a set of monitoring applications. The platform continuously receives raw sensor data from distributed sensors and reliably processes them for display in a monitoring platform for end users. It supports use cases such as detecting sewage overflow events, predicting clogged street drains, and identifying infiltration from unforeseen connections to wastewater systems based on sensor data streams from stationary and floating sensor platforms.
Consortium: The project was a collaborative effort between water utilities (Hamburg Wasser, Berliner Wasser Betrieb), industry (Ingenieurgesellschaft Prof. Dr. Sieker, Walter Tecyard, Funke Kunststoffe, ACO Severin Ahlmann), and research institutions (Technische Universität Berlin, HAW Hamburg).

Reliable Resource Management of Critical Distributed IoT Sensor Systems (2018-2019, sponsored by the Bundesdruckerei Group)
Aim: The goal of the project was to conceive, implement, and evaluate new approaches for the adaptive and dynamic management of distributed and heterogeneous yet trustworthy resources in complex sensor systems.
Involvement: We developed and demonstrated a novel method for obtaining a hardware fingerprint from an analog sensor that can be used for sensor authentication and hardware integrity checks. The approach exploits the characteristic behavior of analog circuits, which is revealed by applying a fixed-frequency alternating current to a sensor while recording its output voltage. By comparing such a fingerprint against reference measurements recorded prior to a sensor's deployment, it can be determined whether sensing hardware connected to an IoT device has been changed by environmental effects or with malicious intent.
Consortium: This was a collaborative research project between the Innovation Department of the Bundesdruckerei Group and the Complex and Distributed Systems group at Technische Universität Berlin, with an interdisciplinary team that included three experts from the industry partner and three RAs at TU Berlin.

I contributed to the following funded research projects as a research assistant:
BBDC: Berlin Big Data Center (2014-2017, funded by the German Federal Ministry of Education and Research - BMBF)
Aim: The project's aim was to develop highly innovative technologies to organize vast amounts of data and to derive informed decisions from such data in order to create economic and social value, with a focus on three exemplary economically, scientifically, and socially relevant application areas: materials science, medicine, and information marketplaces.
Involvement: I contributed to a subproject on "Adaptive Data and Control Flows", aiming to develop a distributed execution engine for distributed data processing that recognizes key characteristics of underlying architectures (CPU, network topology, memory distribution) to implement data partitioning and resource allocation in a way that jobs stay within specified time bounds. For this, we developed new methods that adaptively place data blocks and execution containers for recurring distributed dataflow jobs to balance local data access with distributed job execution.
Consortium: The competence center was managed by the Technische Universität Berlin and involved numerous groups from research organizations in the Berlin/Brandenburg area of Germany, including Freie Universität Berlin, Humboldt-Universität Berlin, Zuse-Institut Berlin, German Research Center for Artificial Intelligence, Fraunhofer FOKUS, and Charité – Berlin University of Medicine, among others.
Link: The project website was discontinued when the project evolved into BIFOLD.
Stratosphere II: Advanced Analytics for Big Data (2014-2017, funded by the German Research Foundation - DFG)
Aim: In its second phase of funding, the Research Unit Stratosphere (FOR 1306) set out to considerably advance the state-of-the-art in designing and building systems for executing complex data analysis programs on massive datasets, building upon the Stratosphere I system (which was also used as the basis for the successful open-source dataflow system Apache Flink) with its runtime system, compiler, optimizer, and scripting languages.
Involvement: I was the RA in a subproject with the aim to develop a "Scalable, Massively-Parallel Runtime System with Predictable Performance", investigating new approaches for dynamic resource allocation for distributed dataflow systems. In particular, we developed novel methods for capturing the scale-out behavior of distributed dataflow jobs, selecting similar previous executions of a job as a basis for accurate performance models, and continuously adjusting resource allocations based on scale-out models to ensure jobs meet their runtime targets.
Consortium: The project involved a consortium of five research groups at Technische Universität Berlin, Hasso Plattner Institute (University of Potsdam), and Humboldt Universität zu Berlin.

HPI-Stanford Design Thinking Research Program (2013-2014, funded by the 'Hasso-Plattner-Förderstiftung' (Hasso Plattner Trust))
Aim: The program strives to apply rigorous academic methods to understand how and why Design Thinking innovation works and fails. Researchers in the program study the complex interaction between members of multi-disciplinary teams challenged to deliver design innovations. An important feature of the domain is the need for creative collaboration across spatial, temporal, and cultural boundaries. In the context of disciplinary diversity, it is investigated how Design Thinking meshes with traditional engineering and management approaches, specifically, why the structure of successful design teams differs substantially from traditional corporate team structures.
Consortium: There were 14 subprojects (seven at Hasso Plattner Institute, seven at Stanford University) in 2013/2014. I was part of the subproject and team of Prof. Robert Hirschfeld at Hasso Plattner Institute.
