Welcome to the research group
Trust in Digital Services at TU Berlin. The research group is headed
by Prof. Dr. Timm Teubner. It was founded in April 2018 and is part of
the Einstein Center Digital Future.
Presentation Day (Data Science Toolbox)
Things got serious for students of our Data Science Toolbox 
course on Thursday at ECDF . After weeks of preparation, nine teams
presented their results on the topic of data-driven decision-making
for a better future. The case studies included the creation of a
prototype, drawing on the Boston open data initiative for supporting
business and public leaders in the areas of financial services, public
services, and sustainability.
Sponsored by Accenture Strategy ,
three outstanding teams were awarded with all-in invitations for a
get-together at Solar Bar & Restaurant , taking place in
"Digital Platforms in E-Commerce"
As part of the weekly lecture series Digital Future , Prof.
Teubner will give a talk on Digital Platforms in Electronic Commerce
(February 5th, 4-6 pm, Room A151).
The lecture series invites
students of all levels to get an understanding of various aspects
connected to the digital transformation. It thus contributes to a more
interdisciplinary education at TUB. There are no participation
Prof. Dr. Thomas Volling (Production and Operations Management)
and Prof. Dr. Timm Teubner (Trust in Digital Services) held their
inaugural lectures at TUB. The event was followed by a cocktail
reception at TU's iconic Geodätenstand.
Talk by Dr. Florian Teschner (HAVAS)
We were happy to host Dr. Florian Teschner as a guest
speaker for our course Data Science Toolbox . In his talk, Dr.
Teschner explored the intricacies of data-based online advertisement.
Since 2017, Dr. Teschner works as head of Data Business Inteligence
(DBi), Havas’ global digital
analytics and marketing technology consultancy.
A growing body of research from various domains has
investigated the platform Airbnb, a two-sided market for peer-based
accommodation sharing. We set out from the idea that it is due time to
take a step back and assess the current state of affairs.
happy to announce that our comprehensive review article  on Airbnb
has eventually appeared, aiming to conflate and synthesize research on
Airbnb. Moreover, a growing online repository  on Airbnb-related
research is now available.
Talk by Prof. Dr. Felix Biessmann (Data Science)
We were very excited to welcome Prof. Dr. Felix
Biessmann for a research talk in the Data Science
Toolbox  course. Prof. Biessmann holds a professorship for Data
Science at Beuth University of Applied Sciences and at the Einstein
Center Digital Future. Being a former PhD candidate at TUB, Prof.
Biessmann talked to our students about Machine Learning Systems in
Production: Data Quality and Interpretability.
the Team, Florence Klement!
Florence Klement joined the TDS research team as a Doctoral
Candidate with a focus on Trust in Crowdinvesting. Florence obtained a
dual master’s degree in Industrial Engineering and Management from
TU Berlin and Toulouse Business School.
"Having worked as Head of Investor Relations at the platform
service provider Companisto  in Berlin-Kreuzberg, I am very
excited to bringing in my expertise in Equity
Special Focus: Privacy
Personal data protection has surged to the center of the policy
debate, leading to the introduction of the EU General Data Protection
Regulation (GDPR). Several BCCP Fellows analyzed the issue of data
privacy from different angles. Have a look what Timm Teubner (TU
Berlin), Christoph M. Flath  (University of Würzburg), and other
scholars have to say about privacy in the sharing economy,
privacy-preserving data analysis, and the price of privacy here
Presentation at ICIS 2018
During this year's International Conference on Information Systems
(ICIS) in San Francisco, Christian Peukert presented one of our recent
research project on the effects of Foreign Live Bio Feedback on human
decision making, particularly when it comes to trust.

Research Talks during the Berlin Science Week
What creates trust in online platforms? What is the economic
value of online reputation? How can reputation be transferred from one
platform to another? These questions were raised by Prof. Dr. Teubner
at the Pairing Research Talks during the Berlin Science Week. The
interdisciplinary format brings together young scientists whose topics
have nothing in common at first glance. more 
Hidden peer-to-peer network
We are happy to announce that our paper  on the hidden
peer-to-peer network structures within accommodation sharing was
accepted at the Journal of Systems and Information
The paper provides first insights into the very
fabric of host-guest interactions on Airbnb from a macroscopic
perspective. We discuss how the platform's network topology may be
leveraged as a resource for trust-building and how platform operators
may use network analyses to gain deeper insights into their user
Platforms Design for Trust
As part of a recent book publication, Prof. Teubner co-authored
a chapter about trust design in the platform economy with Prof.
Greiner (WU Vienna) and Prof. Weinhardt (Karlsruhe Institute of
Technology). The publication is available in German.

shareBW Landeskongress in Karlsruhe
July 4th, 2018
Digitization represents one of the sharing economy's most
important drivers. About 200 participants discussed questions around
economic sustainability of sharing schemes with experts at the shareBW
Landeskongress, including keynote speeches, panels, and best practice
presentations. Prof. Teubner and Dr. Hawlitschek served as anchormen
for two of the scientific tracks at the congress.
Lecture by Max F. Kunz
July 2nd, 2018
In today’s Platform Economics  lecture, Max
Ferdinand Kunz (Co-founder of InStaff & Jobs GmbH)
held a talk on Job-Matching as a Platform: InStaff &
Jobs, introducing the topic of search engine optimization (SEO)
and search engine advertising (SEA).
June 28th, 2018
More than 50 papers and projects have been presented at the
