Interested in health technologies?

The Northeastern University transdisciplinary Ph.D. Program in Personal Health Informatics is accepting applications. Contact me if you are interested in learning more about it or applying as a student (and see this short video). We have a great group of students and are always looking for more.

Since I moved to NEU from MIT, I've been building up my research group in mHealth. I'm looking for students at all levels, ranging from undergraduate students to postdocs. See the website for examples of projects and information about joining. Northeastern made a short "what if" video that summarizes our goal.

Also, if you are local, consider joining the Personal Health Informatics (personal/behavioral health technologies and health informatics) or Mobile (novel mobile phone technologies) mailing lists. I forward relevant announcements to those lists.

If you are looking for faculty positions, note that Northeastern is making major investments in transdisciplinary hires and in personal health informatics. Check the PHI website for more information or contact me if you have questions.

Research interests

Computational sensing, machine learning, and user interface systems for preventive medicine and personal, behavioral informatics; persuasive user interfaces for motivating behavior change; sensor-enabled mobile health technologies; context-aware ecological momentary assessment; experimental ubiquitous computing; living laboratories; perceptually-based interactive environments; pattern recognition and dynamic scene understanding; artificial intelligence; health technology and policy.

I am exploring the development and evaluation of personal, behavioral health informatics – how sensor data acquired throughout everyday life from miniature mobile and in-home sensors might be used to improve wellness via novel human-computer interfaces. This research involves merging ideas from the computer science subfields of pattern recognition, machine learning, computational sensing, and artificial intelligence with ideas from behavioral science, behavioral medicine, social psychology, and preventive medicine. I am particularly interested in how algorithms that recognize everyday activities can drive the development of interactive preventive health tools that could ultimately be applied at the population scale in a cost-effect manner. Within computer science, this requires developing new user-driven activity detection algorithms that use statistical integration of contextual information when large activity training sets are not available. Within preventive medicine, this requires building and deploying pilot systems and demonstrating that the technology does have a real-world impact on health outcomes. As part of this work, my research group has worked to create new tools that can be used to both measure and motivate behavior change taking advantage of emerging sensor-based technologies.  

[Short bio]

Current teaching/advising

In Spring 2016, I am teaching Mobile Application Development (CS 4520/5520) on Mon/Wed (2:50-4:30). I am also teaching Advances in Measuring Behavior (PHTH 5228) on Wed (5:00-7:30).

I am open to the possibility of advising students interested in directed studies on mobile/wearable computing or sensing projects (including using Google Glass, the Pebble smartwatch, and Android Wear devices). Contact me if you are interested:

New Projects (Coming Soon)

I need to make some time soon to update this part of my website. I have new projects on understanding behavior, using Google Glass, studying the behavior of college students, and using smartwatches to transform how we measure behavior for health. Check back...

Physical Activity Measurement on Mobile Phones

How can we use mobile phones, or phones augmented with additional miniature wireless sensors worn on the body, to detect detailed information about physical activity for health research? We are building an open-source hardware and software system to measure physical activity type, duration, intensity, and location for gene-environment interaction studies. See

Portable In-Home Data Collection

How can we easily instrument homes for doing research on ubiquitous computing and health technologies? We are building tools for in-home monitoring and developing datasets that can be used as a shared community resource. Essentially, we are creating a portable version a live-in multi-modal sensing system.  See

User-Driven Pattern Recognition

Most pattern recognition algorithms that detect activity and context from in-home or wearable sensors assume the recognition system is a black box. However, we have reason to believe this will not work in practice, and we are conducting research on how one might create inference algorithms where end-users who know nothing about pattern recognition algorithms play a key role in sensor installation, sensor maintenance, algorithm training, and error correction. This requires rethinking the algorithms we use in the first place for activity recognition.

Operant Conditioning for Motivating Behavior Change

How can mobile devices motivate behavior change? One way might be to wait patiently, automatically detecting when someone does something just a bit better than what that person normally does using sensors such as accelerometers... and then providing context-sensitive, tailored encouragement. In other words, software on a mobile device might use computational sensing to detect behavior, and operant conditioning to motivate gradual behavior change.

Motivating Weight Loss Among Young Adults using Mobile Phones

With Duke Medical School researchers, we are developing and testing a mobile phone weight loss and weight maintenance application that operates entirely on mobile phones, using sensors built into the phone, Bluetooth scales, and social networking strategies to deliver a novel weight loss intervention that may scale well in cost. The effectiveness of the application for a two-year period will be evaluated in a randomized clinical trial. The project is in the application prototyping phase.

The PlaceLab

How can ubiquitous computing technologies be created that work for extended periods of time? How can persuasive interfaces designed to motivate behavior change in the home be studied in context? My research group, in collaboration with our partner TIAX, developed the PlaceLab - an apartment-scale shared research facility in a residential condominium building in Cambridge where new technologies and design concepts could be tested and evaluated in the context of everyday living. For a sense of the capabilities it had watch the PlaceLab overview video, or this more lighthearted video that demonstrates all the sensing. The PlaceLab had be closed down, and was replaced by the BoxLab.  

MITes (portable sensors)

The House_n group has developed a kit of wireless portable sensors that can be easily deployed in homes and offices for studying behavior and creating and evaluating novel context-sensitive human-computer interface systems. The sensors have been extensively tested (some in the PlaceLab), and they have been adopted by other research groups. They include sensors for measuring object motion, acceleration, current flow, heart rate, ultra-violet light, indoor position, and more. The mobile version of the sensors evolved into the Wockets.  

Computational perception and persuasive user interface design (multiple projects)

Can computers with computational sensing motivate behavior change? In my lab we are working on several projects using mobile and ubiquitous computers to both measure and motivate behavior change. We are studying the intersection between new user interface design strategies, computational tools for studying behavior change, computational learning algorithms for context recognition and planning, and behavioral and social psychology.  We focus on the evaluation of algorithms and devices we create in real environments. Much of this work involves measuring and motivating physical activity and healthy eating. A recent project developed a "GPS Thermostat" system that may encourage less energy use.   

Context-aware experience sampling tools (multiple projects)

How can we design tools for researchers in a variety of fields that help them study people in real contexts? We are developing novel tools for mobile computing devices that can gather data for both computational and public health studies in actual home settings. These tools use variations on a technique we refer to as context-aware experience sampling. We are exploring the viability of these tools on common mobile phones for large-scale medical research studies.   

Ubiquitous computing (circa 2005) (multiple projects)

In the House_n lab, we created a home-like pervasive computing environment with sensing systems, ubiquitous display, and laser pointer interaction. The room provided a platform for investigating the implications of ubiquitous computing on life in the home, and the future of user interface design. I am particularly interested in the symbiotic relationship between architectural design, computational sensing design, AI, and user interface design. How will fusing ideas from these fields enable new devices and spaces that impact our lives in meaningful ways in the future?

quakercolor.gif (5164 bytes)Recognizing multi-agent action
(circa 1999)

The goal of this research was to develop algorithms that integrate contextual domain knowledge and computer vision feature detection to interpret and describe events in sequences of video. In particular, the algorithms must handle scenes with multiple people interacting with each other. To demonstrate how this can be done, I designed a system that automatically labels actions and states in a football play such as "passing" "blocking" and "R34 run play" using probabilistic models.

kidsroom.gif (26688 bytes)The KidsRoom
(circa 1997)

The KidsRoom was an interactive, narrative playspace for children. It was one of the first interactive environments to handle multiple people interacting with each other.  The actions of the children, who were in a real bedroom overlooked by several video cameras, were interpreted by computer vision tracking and action recognition algorithms. A narrated story encouraged children to move around the room and established context for the sensing algorithms. This created a unique interactive experience. A commercialized version of the system developed by NearLife for the British Millennium Dome won an interactive media design award from Id Magazine.

track-rt.gif (1597 bytes)Real-time tracking
(circa 1997)

This work, developed with Jim Davis, extended the idea of context-sensitive tracking to a real-time domain and was used extensively in the KidsRoom.   Multiple objects are tracked in real-time from an overhead view from a video camera.

cw-track.gif (37980 bytes)Context-based tracking
(circa 1994)

This work explored the use of contextual information for tracking of multiple, interacting objects simultaneously.  The goal was to automatically track football players in high-cam video of a football play. The low-resolution, colliding, blob-like players pose a problem for most conventional tracking algorithms, but knowledge about the rules of football and likely events in time can be used to resolve some tracking ambiguities.

kidsl.gif (12068 bytes)kidsr.gif (12194 bytes)

Large-occlusion stereo vision
(circa 1993)

Real stereo scenes with people typically contain large occluded regions. This work developed a computational stereo algorithm that is unaffected by the presence of large occlusion regions, permitting more accurate recovery of occlusion boundaries.
