Visiting Hari Sundaram at University of Illinois Urbana-Champaign

Visiting Hari Sundaram at University of Illinois Urbana-Champaign

Hari Sundaram is a professor in the Department of Computer Science at the University of Illinois Urbana-Champaign. It was a pleasure meeting Hari whom I know for so many years now. It was a pleasure meeting him in his new environment at UIUC and also hear about his passion on enabling cooperative behavior adoption on a large scale and shaping social network behavior. Hari also introduced me to his colleagues and Phd students of the departments. Helen Wauck is a PhD student in the field of HCI who is working on video games to teach different aspects of spatial reasoning skills. Her advisor is Wai-tat Fu, a professor in the Department of Computer Science who is heading the Cognitive Computations and Social Dynamics lab. It was a nice surprise that Wai-Tat will be spending his coming sabbatical in spring 2016 actually in the neighborhood of Oldenburg. He will be a guest scholar at the Hanse-Wissenschaftskolleg (HWK), a foundation of the federal states of Bremen and Lower Saxony and the city of Delmenhorst and work together with my colleague Christian Freksa at the University of Bremen. It will be a pleasure to invite Wai-Tat also to Oldenburg and advise on the ongoing research project SOCIAL (facilitate spontaneous and informal communication in spatially distributed groups) funded by the DFG which Christian Freksa and I am currently running. It was also a pleasure to meet Karrie Karahalios who leads the Social Spaces group and her students John Lee and Hidy Kong. They provided my an overview of a very exciting recent research projects – looking forward to see it published.

Visiting Katie Siek at the University of Indiana Bloomington

Visiting Katie Siek at the University of Indiana-Bloomington

After I met her a few times before and great events  looking into the future of pervasive health (such as the Dagstuhl Seminar on Life-long health behavior change technologies) it was a pleasure to meet her in her current research environment. Katie Siek is a Professor at the University of Indiana – Bloomington and a very active researcher in the field of pervasive health. It was a pleasure to also meet Sriraam Natarajan, who is working in the field of machine learning. Recently he is working on very interesting analysis of health data. On of the projects aim to predict events, such as risk to cardiovascular diseases, increase in coronary artery calcification levels, ER (emergency room) readmission etc. from longitudinal data using machine learning – very interesting. With Raquel Hill, who is a professor in Computer Science I discussed the notion of trust in computing systems. This relates to ongoing research in Oldenburg in in which my colleagues are studying the role of trust in automotive user interfaces. I also met Tanja Singh who involved in a research project on  with low socio-economic status. The check-in tree is very interesting and also very related to our work in CONTACT for connecting persons in palliative care with their loved one. Looking forward to the results of the studies and new prototypes. Thank you UI–Bloomington for this nice visit.



Visiting Pedja Klasnja at the University of Michigan

Visiting Pedja Klasnja at the University of Michigan

At the University of Michigan I met Pedja Klasnja, who is a professor of Information, School of Information and Assistant Professor of Health Behavior and Health Education, School of Public Health. He is an active reseacher in the field of HCI and health. We recently  organized a Dagstuhl seminar on „Life-long health behavior change technology“ together. We used the time to talk about the follow up activities and commitments that came out of the workshop – so stay tuned. With Eytan Adar who is an Associate Professor of Information and Computer Science at the University of Michigan I talked  about large scale dating and the mechanisms to explore late data collections. We talked about the challenges of Information Visualization and Information Retrieval and our work in the field of  sophisticated visual interfaces and ranking methods to enable end-users in discovering knowledge hidden in multi-dimensional geospatial databases (UrbanExplorer, (video).

I was also giving a talk in the department and very interesting discussions on meaningful moments for digital interventions with Susan Murphy from the School of Public Health and Imbal (Billie) Nahum-Shani from the Institute for Social Research. A very interesting work my team will be looking into is the notion of how to run digital intervention studies. The work on micro-randomized trials is a very promising approach to run different kind of experimental conditions of mobile digital interventions to better learn about mobile health interventions. We will definitely look into it.

Visiting Anind Dey at Carnegie Mellon University

Visiting Anind Dey at Carnegie  Mellon University

It was a pleasure to visit Anind Dey and meet faculty and students from the from the HCI Institute at Carnegie Mellon. It was a pleasure to give two talks, one on „Interaction Design for Interactiver Personal Health“ as well as on our research in the field of „Pervasive Light Displays for Daily Acitivities“. It was a pleasure that – given the summer – such a nice audience attended the talks which was highly interacting and the interesting questions and discussions.

Grace Sangwon Bae introduced me into her work on tracking health behavior with sensors and its application in the field of alcohol abuse and but also in the field of congestive heart failure. Thank you for sharing these interesting results in this area. Adrian Defreitas showed me his very interesting work on Impromptu, an App and Service that contributes to the world of internet of things by easily retreiving and connecting to objects and services at a certain location. It was nice to meet Seungjun Kim again who also was at PervasiveHealth 2014 in Oldenburg. He showed my a very rich collection of his work in sensor augmentation, sensor data mining, qne quality of life technology. There are many connections of his work on interruptibility in the car to our work on the Automotive domain and in the field of ambient assisted living. Afsana Donab introduced me into her research on exploiting context for the application of time banking in neighborhoods and communities. Chris Harrison also had some time to chat about their recent work in gessture recognition and object touching that will be shown at UIST this year.

Visiting Tanzeem Choudhury at Cornell in Ithaca

Visiting Tanzeem Choudhury at Cornell

Tanzeem Choudhury is leading the  People Aware Computing group at Cornell. It was very interesting to talk with her team. Hane Houng is post doc in the lab and also a visiting lecturer at the Human Computer Interaction group at University College London. I met Hane last year at PervasiveHealth 2014 which we organized Oldenburg. Marc Matthews is a Marie Curie post-doctoral fellow working in the field of mental health and tools supporting management of bipolar disorder. It was also a real pleasure to talk to Mashfiqui Rabbi, Saeed Abdullah, and Alex Adams about their recent projects.

I really like the group’s work on personal management of mental health. Their work on MyBehavior is about a smartphone app that delivers personalized health suggestions and will be presented at UbiComp 2015. Other projects involve BodyBeat novel mobile sensing system for capturing and recognizing non-speech body sounds was very interesting as well is the work in the field of food and plates. Thank you for sharing all of this with me.

Visiting Nevenka Dimitrova at Philips Research North America in Briarcliff Mano

Visiting Nevenka Dimitrova at Philips Research

I had the pleasure to meet Nevenka Dimotrova again, after all these years. Nevenka and me were active researchers in the ACM SIGMM community and working in the field of multimedia.  We did not meet sind probably about 10 years and it was a pleasure to see each other again.

Nevenka has moved into a great new field of genomics and the application of pattern recognition in genomic resources. Her current research activities are in bioinformatics and biomarker discovery and how to enable decision support systems for personalized medicine. Nevenka is leasing the team at Philips working on PAPAyA, for Platform for Personalized Analytics Applications „to help oncologists analyze, interpret, and interactively present data from next-generation sequencing instruments in order to prioritize treatment for cancer patients.“

It was also nice to talk to different people working in health related areas here at Philips such as Portia Taylor and Mladen Milosevic who focus in the area of personal health and mobile health technologies.. It was a real pleasure to talk and exchange!

Visiting Cornell Tech in NYC – Mor Naaman

Visiting Mor Naaman at Cornell NYC Tech

A few days in THE CITY 🙂

I really enjoyed visiting Mor Naaman who is a professor at Cornell Tech and a good research friend from times back when my research work was more focused on personal media and social media context for automatically creating photo books and visiting ACM Multimedia. Mor’s work is focusing on understanding social media content and social media usage and interactions – very interesting. Over wonderful Korean food I joined the weekly group meeting and was invited to talk about recent research projects of Mor’s students. Thank you for sharing this with me!

Visiting the lab, I also had the opportunity to meet Shiri Azenkot and her students who were showing their ongoing work with us. It was a pleasure to see the recent projects in the field of accessibility as we were looking into vibro-tactile displays for the blind in previous work.

And, small world, I just met Lexing Xie, who is a Senior Lecturer / Fellow of Computer Science at Australian National University and we took the chance to chat and also took a quick selfie.


Visiting MIT Media Lab – FLUID Group of Pattie Maes

Visiting Pattie Maes at MIT

During my trip I also had the opportunity to visit the Fluid interfaces group at MIT Media Lab which is lead by Patties Maes. I was giving a talk on „Pervasive Light Displays“ and enjoyed the discussions and am thankful for the interesting questions that are also inspirations for our work. Roy Shilkrot, who has just completed his PhD at MIT Media Lab (congratulations again!), was so kind and presented ongoing interesting research projects of the group to me. Specifically his work on accessibility with FingerReader and EyeRing are very fascinating as accessibility for blind and visually impaired people is also a strong research topic at our lab. Roy also quickly introduced me to some of the other labs such that I had the chance to look at recent prototypes of the Tangible Media Group lab of Hiroshi Ishii.

It was also very interesting to talk to Nan Zhao from the Responsive Environments group of Joe Paradiso. As my group is working in the field of pervasive light displays her project on experimental lighting is very interesting and fascinating for us. Nan also showed me some more exciting ongoing work. I am looking forward to see here recent results and video online once it is presented at International Symposium on Wearable Computers (ISWC) later this year.

It was also great to meet a researcher I have not met for some years: Vivek Singh is now a Visiting Assistant Professor in Alex Pentland’s Social Media group. I remember him from 2009 when he was still a PhD student and received a best paper award for his work on Motivating contributors in social media networks at first SIGMM workshop on Social media which I co-organized in 2009. What a pleasure to meet him again and to talk about his ongoing work on behavioral informatics and the research group he started at an Assistant Professor at Rutgers University.


Visting Misha Pavel and Holly Jimison at Northeastern University

Visiting Misha Pavel and Holly Jimmison at Northeaster University

Just two weeks after Misha Pavel and I met at the Dagstuhl Seminar on Life-long health behavior change seminar, I visited him and his colleague Holly Jimison at Northeastern who are both faculty in College of Computer & Information Science and Bouvé College of Health Sciences. We met with their colleague Stephen Intille and several students of the lab. We spent some time discussion about the inspiring week in Dagstuhl with interdisciplinary researchers and what were the most exciting outcomes of this week. I was also giving a talk on „Multimodal Interfaces for Attention and Situation Awareness in Automotives“ and enjoyed the very lively discussion with the audience. Thank you for the great visit and also the nice dinner.
