Mobile Sensing Technology
Smartphones and other mobile devices are ubiquitous in many people's everyday lifes. Equipped with lots of sensors and connectivity, it is possible to assess or approximate many aspects about the user's actions, context and environment. Thereby they can be leveraged to collect data for interdisciplinary research, fuel adaptive applications, or feed crowd-based data platforms. In my research I investigate how mobile devices' passive sensing capabilities can be leveraged for the aforementioned purposes, while protecting the user's privacy. That encompasses but is not limited to interaction approaches that include the human more in the data collection process and on-device feature extraction procedures.
The Impact of HCI on our Societies
Ubiquitous technologies, most prominently smartphones, have spread within people's everyday lives in the past 15 years. It changes how we communicate with others, how we gain information, and what kinds of content we consume. Sources of information have been rapidly evolving from classical, big media organizations such as televisions and newspapers to a plethora of smaller organizations or individuals from which we collect our daily news and information on specific topics. The choice of content, often selected by large platform algorithms, subconsciously influences our beliefs and opinions. This can lead to targeted manipulation of whole societies, as the Cambridge Analytica scandal has shown in the context of the Brexit and 2019 US election vote.
With my research, I want to improve the understanding of the influence of ubiquitous technologies on our societies. Through a better understanding of the related psychological and social dynamics, I envision that HCI can contribute to the positive development of our society and mitigate current issues such as political polarization and populistic tendencies. In my eyes interdisciplinary collaboration is crucial in this field - I am thereby happy to exchange thoughts and seek collaborations with other fields!

How can Technology Support Sustainable Behavior?
Although the majority of the german population describes themselves as green, fewer people actually behave so [Terlau, Hirsch 2015]. In my research I investigate how technology can help to overcome current barriers hindering sustainable behavior. It includes (among others)
- the study of technology that can increase the awareness of behavior's impact and its quantification
- finding ways to assess information about the footprint of consumption goods, and provide it in an opportune manner
- an investigation of the influence of group dynamics and social context
- the evaluation of insights of the field of Persuasive Technology in the domain of sustainability
If you want to get an overview of my latest research in the area of pro-environmental behaviour, I recommend to watch my talk at the Public Climate School 2020 (in German):
Personal Informatics: End User Data Science
Building on the aforementioned area of Mobile Sensing, I in the next step aim to enable the user take make use of their data. Current mobile devices offer only rare options to generate insights from the collected data, the magic usually happens on company servers somewhere in the cloud. I explore projects where users is given the ability to gain insights from their local data themselves. Therefore I am looking for solutions on several uncertainties, e.g. what is technically possible locally on a mobile device with one-person-data at all, or how interactivity can be brought into actually complex prediction procedures.
PhoneStudy
The PhoneStudy project is an interdisciplinary Mobile Sensing research project, brought to life by the chair of Psychological Methods and Assessment, Mediainformatics, and Computational Statistics. Its integral part is the PhoneStudy research app, that assesses behavioral and contextual data of study participants in the wild. The data is then used to investigate the relationships between personality, emotions and people's behavior. As lead developer of the PhoneStudy project I coordinate the development and maintenance of the PhoneStudy apps and infrastructure since November 2018. I've been in charge of technically managing a handful of studies, ranging from university internal ones to collaboration projects across multiple German universities and panelists. In our most recent project we created a german representative benchmark dataset encompassing 800 participants for 3 to 6 months. Furthermore I use the PhoneStudy project as solid basis for most of my mobile sensing based research projects and theseses.
Zur vergebenede Theses und Praktika
As I am finishing my PhD and might leave the lab this summer, I unfortunately don't have capacity to start further thesis supervisions besides the here listed cosupervisions.
