Dr. David Eckhoff

I am one of the principal investigators at TUMCREATE, Singapore, leading the computer science team. My research focuses on future transportation technologies, simulation, the smart city, and privacy.


Two accepted Research Proposals

1st June 2019

tumcreateTwo of my research proposals for the 5th round of the Intra-CREATE seed call have been accepted. In the first one, where I act as a Co-Investigator, we would like to compare the research in the simulation domain among the many CREATE entities such as MIT, ETH and TUMCREATE. We all have our simulation tools (CityMoS, MATSIM, SimMobility) but no common foundation in terms of data and scenarios. We would like to learn more about the trustworthiness and reproducibility of traffic simulators and give insights to what extent our simulations agree and more importantly, where they don't. The second proposal which I was leading is a collaboration with the University of Illinois-Champagne, NUS, NTU and my long-term peer Dr Isabel Wagner from DMU Leicester. We want to continue our research on privacy protection in smart cities and developed a common framework to manage and analyse privacy risks in complex, interconnected systems. This common framework has been on Isabel's and my plans for a long time and I can't wait to start this exciting project, especially given the chance to welcome Isabel back to Singapore for two short research visits.

Best paper at DS-RT 2018

20th November 2018

bestpaper_dsrtWe received the Best Paper Award at the "22nd International Symposium on Distributed Simulation and Real Time Applications (DS-RT)" held in Madrid in October. This symposium, now in its 22nd iteration, serves as a forum for both academia and industry to present recent research results in the domain of distributed simulation. Our award-winning paper explores possibilities to substantially improve the performance of traffic simulation by using not just conventional processors (CPUs) but also incorporating graphics cards (GPUs). One method is to compute parts of the traffic simulation both on CPU and GPU. Additionally, we show how the simulation can be moved to the GPU entirely, significantly increasing the simulation speed.

Best paper at PADS 2018

14th June 2018

bestpaper_padsWe were awarded the best paper award at ACM SIGSIM PADS 2018! The ACM SIGSIM Conference on Principles of Advanced Discrete Simulation (PADS) is a prestigious and unique forum for Simulation and Modeling. In our paper, we propose an innovative method to improve the performance of traffic simulation. The basic concept is to avoid unnecessary computation by dynamically reducing the update frequency. The proposed method enables more timely results in traffic simulation studies without compromising accuracy.

Talks Talks Talks

13th April 2018

This week was rather busy as I had to give three (different) presentations within two days. First, I was invited by the Singapore-ETH Centre to give a talk on how to write proposals and acquire funding. It was a lot of fun to talk to 40+ other early career researchers and discuss the funding landscape of Singapore. Secondly, a delegation of some 50 Roland Berger (and other) consultants visited TUMCREATE and I gave a presentation in the CREATE theatrette on Smart Cities and how intelligent transport systems can be simulated. Lastly, we were honoured by the visit of a team around Detlev von Platen, a member of the executive board of Porsche. In a small circle, we had the chance to discuss our research and the role of automotive OEMs in future cities.

Some updates on publications

17th Mach 2018

My paper together with Dr Isabel Wagner "Technical Privacy Metrics: A systematic Survey" has been accepted to ACM Computing Surveys. This work has been in the making since 2015 and it is nice to see that it has now come to completion. I also published two articles in the journal Elsevier Computer Communications, one with my colleague Rainer Stahlmann about the exploration of GLOSA systems, the other one on readjusting the privacy goals in vehicular networks, together with my colleague Prof Christoph Sommer. Lastly, my book chapter for the 'excellent dissertations' series by the German Computer Scientist Society (GI) is now finally available. All the articles mentioned can be found as an author's version on my website.

Visit of 2nd Mayor of Munich

9th December 2017

munichTUMCREATE hosted a delegation from the City of Munich consisting of the 2nd Mayor of Munich, BMW, Infineon, UnternehmerTUM, TÜV SÜD and Prof Manfred Broy. I had the honor to present our research to them and engage in interesting discussions on how the research conducted in Singapore can be transfered to Munich.

Accepted Research Proposals

7th December 2017

tumcreateTwo of my research proposals were accepted by the National Research Foundation, Singapore. The first is a collaboration together with Nanyang Technological University (Prof Anwitaman Datta) and MIT/SMART (Dr Iva Boijc) and deals with privacy protection in mobility data. The second proposal together with MIT, Berkeley, and ETH looks at mobility solutions in the case of public transport disruptions. I'm eager to start working in these exciting projects and we are actively looking for researchers who want to spend some time in Singapore.

IEEE Communications Surveys and Tutorials

Sep 2017

citizenMy paper "Privacy in the Smart City -- Applications, Technologies, Challenges and Solutions" (together with Dr. Isabel Wagner) has been accepted for publication in IEEE Communications Surveys and Tutorials, which is currently the journal with the highest impact factor in Computer Science. The article can already be accessed via IEEE Xplore and will be published in one of the upcoming issues. It provides useful taxonomies and a detailed overview of smart city applications, technologies, privacy types, and attacker models.

Visit of State Secretary Odenwald

8th July 2017

TUMCREATE hosted a delegation from the Federal Ministry of Transport and Digital Infrastructure (BMVI) led by State Secretary Mr. Michael Odenwald. I gave a presentation on the current research activities in my group. The discussion included sharing on Intelligent Transport Systems, as Singapore and Germany both face issues pertaining to public transport, emission reduction, and autonomous vehicles.

LNI Dissertation Award Talks

23rd May 2017

I travelled to Germany to present my thesis to the committee of the GI Dissertation Award. The event took place at Schloss Dagstuhl with a total of 30 talks from nominees from all over Germany, Austria, Switzerland. The quality of these talks was high throughout, and it was very refreshing to learn about the advances in all these different fields of computer science.
