U of M Wins $4M for Mobile Research

A research team at the University of Memphis (U of M) won a $4 million grant from the federal government to refine data collected and shared through the mobile sensors in mobile phones, vehicles, and more.

The five-year grant will help the Memphis team to make improvements to the “extremely noisy” data collected through mobile sensors. The team includes Santosh Kumar, Ida Sim, Mani Srivastava, and Zachary Ives.

The team will focus specifically on health data gleaned from mobile sensors and its work will make that data more usable for scientists and engineers.

“This grant will help make research opportunities available that provide real-world, hands-on experience and pave the way for ground-breaking research on health data collection,” Rep. Steve Cohen said in a statement. “I am pleased to see the continued federal investment in the University of Memphis.”

The award was granted by the National Science Foundation’sAdvanced Cyberinfrastructure Division.

The U of M released the following news release on the project Thursday morning:

The University of Memphis will lead a team of researchers from three other universities — UCLA, UC San Francisco, and University of Pennsylvania — on a data cyberinfrastructure grant by the National Science Foundation (NSF). The team will develop a new cyberinfrastructure, called mProv, to annotate high-frequency mobile sensor data with data source, quality, validity, and semantics to enable sharing of such data with the wider research community.

The project, mProv: Provenance-based Data Analytics Cyberinfrastructure for High-frequency Mobile Sensor Data, will be led by Dr. Santosh Kumar, a professor and Moss Chair of Excellence in Computer Science. Dr. Zachary Ives, another computer scientist, will lead the University of Pennsylvania team, Dr. Ida Sim, a professor of Medicine and medical informaticist, will lead the UCSF site, and Dr. Mani Srivastava, an electrical engineer and computer scientist, will lead the UCLA team. Other collaborators on the project include Open mHealth, Open Humans, and Quantified Self.

Mobile sensors (embedded in phones, vehicles, wearables, and the environment) continuously capture data in great detail, and hold tremendous potential to advance science, and to directly impact health, wellness, mobility/transportation, and energy. The open-source software developed by the NIH-funded Center of Excellence for Mobile Sensor Data-to-Knowledge (MD2K), also led by Kumar and involving UCLA and UCSF, allows any researcher to collect, analyze, and interpret high-frequency sensor data from the natural environment. However, research with such sensor data is still out of reach for most researchers; it involves significant resources and expertise to acquire sensors, obtain study approval, and recruit human subjects before collecting the data.

By developing a provenance cyberinfrastructure that will integrate metadata with streaming sensor data, the mProv project will enable sharing of mobile sensor data with third party researchers. It will accelerate research by tapping into the growing interest by the research community and unleash the potential of mobile sensor data to improve health and wellness on an individual level by developing computational models of human health and behavior.

Said Kumar: “With the mProv provenance cyberinfrastructure complementing MD2K’s software, investigators can collect, curate, analyze, and interpret mobile sensor data, as well as share data. Doing so can amplify the research utility of their data and, most importantly, help establish benchmarks and bring reproducibility, which are key to scientific rigor.”

“The mProv tools will make it convenient to generate and propagate metadata for streaming sensor data,” said Ives.

Said Sim: “The infrastructure will accommodate a wide variety of data types and will enable data discovery, analytics, and visualization from third parties, including researchers and industry.”
Srivastava noted that “To address the privacy concerns associated with data from mobile personal sensors, our team will also investigate privacy mechanisms to ensure privacy of data contributors, while allowing research using their data.”

University of Memphis President M. David Rudd added, “This $4 million grant represents the largest single NSF award received by the University of Memphis and reflects our growing reputation as a hub for mobile sensor ‘big data’ and mHealth research, as well as Dr. Kumar’s national and international reputation as a leader in this field.”

“Earlier this year, Google cited the MD2K Center at the U of M as a reason why Memphis was named the Digital e-Capital for Tennessee,” said Dr. Andy Myers, Vice President for Research at U of M. “The new mProv project builds upon the MD2K project, and further enhances the University of Memphis’ nationwide reputation as a hub for mHealth research.”
