mHealth Connect aims to improve the use of physical activity wearables and apps for clinical purposes by bringing together device and app developers with a diverse group of clinicians and researchers.
This year we invite the general public to join us on the first day of the event, Tuesday, April 18, 2017, at Stanford University. Connect with device and app developers, clinicians, and researchers who are generating new insights with these devices. Hear how organizations are currently utilizing consumer wearable devices to change the way they operate, the challenges they face, and their vision of the future. Speakers include:
- David Shaywitz – Chief Medical Officer, DNAnexus
Co-Founder and West Coast Innovation Lead,
Center for Assessment Technology and Continuous Health (CATCH), Massachusetts General Hospital
- Michael Snyder – Professor of Genetics, Stanford University
- Spyros Papapetropoulous – Vice President, Global Development Head, Neurodegenerative Diseases and Movement Disorders,
Teva Pharmaceutical Industries
- Laura Wilt – Senior Vice President, Chief Information Officer, Ochsner Health System
- Cedric Hutchings – Vice President, Digital Health, Nokia Technologies
Co-founder and past CEO, Withings
Attendance is free, but you must register in order to attend. If you cannot join in person, you can register to watch the live stream.

Mobilize Center graduate student Tim Althoff, Computer Science graduate student Pranav Jindal, and Mobilize Center faculty Jure Leskovec published a research paper in Proceedings of the Tenth ACM International Conference on Web Search and Data Mining (WSDM 2017), where they investigated the effect of social networks on users’ online and offline behaviors, including user engagement, retention, and physical activity levels.
The results are based on an analysis of data from 6 million people from over 100 countries collected over a 5-year period using the physical activity tracking application Argus. Althoff and colleagues found that participating in the social network increases both in-application activity as well as physical activity levels. They were also able to take advantage of a natural experiment within the dataset to distinguish between correlation and causation.

Mobilize Center Postdoctoral Fellow Lukasz Kidzinski has organized a challenge to make a musculoskeletal model walk as far as possible in a virtual environment in 5 seconds using a reinforcement learning approach. The winner will be invited to the 2nd Applied Machine Learning Days at EPFL in Switzerland on January 2018, with travel and accommodations paid for (see program for 2017 event here).
The challenge focuses on programming a model of the brain’s motor control unit, which controls movement, within the OpenSim simulation environment. Understanding how the brain functions in normal conditions and for neurological disorders, such as cerebral palsy, multiple sclerosis or stroke, is key to improving treatments for these disorders.

Mobilize Center postdoc Jessilyn Dunn and colleagues published a research paper in PLOS Biology where they recorded over 250,000 daily physiological measurements from 43 participants using multiple wearable devices to investigate the role of these devices to diagnose and analyze disease. Combining the information from these devices and from medical measurements, such as heart rate and oxygen levels, researchers found these devices could be used to identify abnormal physiological signals, in this case arising from the onset of Lyme disease. The signals also showed differences between being insulin-sensitive versus insulin-resistant, raising the possibility of using these devices to help detect the risk for type 2 diabetes.

Mobilize Center researcher Thomas Uchida and OpenSim researchers published a paper in PLOS One where they generated muscle-driven simulations of movement to augment experimental data and provide insights into the design of assistive devices to reduce energy consumption during running.
Using the open-source OpenSim software platform, they simulated 10 human subjects running at 2 and 5 m/s to examine the predicted changes in muscle recruitment patterns and metabolic power consumption with assistive devices.
Results from the simulations yielded observations that can be used to form hypotheses for future experimental studies.

Mobilize Center graduate student Tim Althoff and Mobilize Center faculty member Jure Leskovec published a research paper in the Transactions of the Association for Computational Linguistics Journal where they conducted a large-scale quantitative analysis of over 600,000 text messages from 15,555 counseling conversations. They developed novel computational methods such as a sequence-based unsupervised conversation model and psycholinguistics-inspired word frequency analyses to learn how various linguistic aspects of conversation are correlated with conversational outcomes.
Results from the analysis yielded five strategies that successful counselors utilize. Read the full article

The Workshop on Machine Learning will take place at the Twenty-Ninth Annual Conference on Neural Information Processing Systems (NIPS 2016) in Barcelona, Spain, on Friday, December 9, 2016. The deadline to submit an extended abstract is October 28, 2016.
The purpose of the workshop is to bring together clinicians, health data experts and machine learning researchers to discuss how statistical learning can enhance both science and the practice of medicine. Mobilize Distinguished Postdoctoral Fellows Jason Fries and Madalina Fiterau are part of the organizing committee.
Learn more about the workshop and abstract submission process.
The NIH is hosting a conference “Rehabilitation Research at NIH: Moving the Field Forward” on May 25-26, 2016 to discuss the range of rehabilitation research projects funded by the NIH and to gather feedback on the development of the recommendations for the NIH Rehabilitation Research Plan. Panel discussions include a discussion of telemedicine and smartphone apps in rehab (“Bending the Arc of Technology Toward Rehabilitation and Health) and the use of big data in rehab (“Using Data to Drive Discovery”). Dr. Jennifer Hicks, the Mobilize Center Director of Data Science, will present a talk on how our Center uses data from wearable sensors, research labs, and clinics to understand and improve human mobility.
