Current Research

Mobile Sensing Technology + Privacy

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.

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.

If you are interested in one of my topics and would like us to collaborate or exchange ideas and thoughts, feel free to contact me - I'd be happy to talk about it!

Further Research Interests

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

My aim is to deploy technology that makes the user aware of the impact of his or her behavior, and help people to bridge the attitude-behavior gap.
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):

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.

Open Theses and project work

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.

Open Positions as HiWi and Working Student

Tutors for the lecture Online Multimedia for WiSe 2024/25 wanted!

If you have experience with web development, and would like to apply your knowledge to support other students, we would love to have you on board! It would also be good (but not mandatory) if you already attended the lecture yourself. Tutor positions are paid and can additionally be accounted as PSK in some fields of study. If you are interested, please drop a message to Florian Bemmann and Teodora Mitrevska.
