2019 Funding Opportunities

From bench to bedside: the CMLH funds projects that strive to bridge the gap between research and practice. All funded work at CMLH will have a clear line of sight to commercial application. Although many CMLH projects will involve data analytics and machine learning, our approach is technology agnostic. We welcome proposals that involve human-computer interaction, language technologies, information systems, computer graphics, computer vision, artificial intelligence, robotics, electrical engineering, economics, psychology, sociology, public policy, business administration, law, design, and any other disciplines that apply to healthcare.

CMLH initially provides research projects with approximately one year of funding. After one year, projects may attract more funding to refine the technology and/or its development for commercialization.

In addition to offering funding, CMLH provides support for funded projects in the form of datasets, access to patients and doctors for empirical validation of new concepts, and entrepreneurial mentorship.

Awards are intended to support research that transforms healthcare from transactional and experience-centered to data-driven. Once selected for an award, the CMLH and UPMC Enterprises will help identify potential clinical and data-transaction partners and provide guidance related to commercialization activities, as needed.

Proposal submissions are open only to Carnegie Mellon faculty in all units of the university. All proposals should be submitted via email to: cmlh@cs.cmu.edu.

Projects

Clinical Genomics Modeling Platform

Project Summary

The Clinical Genomics Modeling Platform is an engine for easily building precision-medicine models for various diseases and populations. Triage algorithms, for instance, might help to determine if patients with a certain disease should be sent home with monitoring or sent to the intensive care unit.

Their project focuses on the understanding of the relationship between genetic variation and medical outcomes in a large population, which is key to realizing the vision of personalized medicine. Efforts are now underway to obtain the genome sequences of thousands of individuals, and as the cost of sequencing continues to drop, it will become routine to sequence patients in a medical setting. However, a number of computational and practical challenges remain in the way of using genomic sequencing for clinical decision making.

In this project, Dr. Carl Kingsford and Dr. Christopher Langmead are aiming to increase the usage of predictive systems based on machine learning techniques and genomics through the development and commercialization of a computational system that will

  • Make predictive models easy to build for clinical researchers
  • Make predictive models easy to share (sell) and apply
  • Make results of models easy to understand

Researchers

This project is led by Dr. Carl Kingsford and Dr. Christopher Langmead, both associate professors of computational biology with the School of Computer Science.

Computational Modeling of Behavioral Rhythms to Predict Readmissions

Project Summary

Readmission after complex cancer surgery is common, with studies reporting between 15% and 50% of patients being readmitted within 30 days of discharge from the hospital. Readmissions are associated with increased healthcare costs, poor clinical outcomes including increased risk of infection and early mortality, and patient and family stress and suffering. Prior research has identified demographic and clinical predictors of readmission, but the role of patient-centered behavioral processes remains relatively unexplored. Identifying behavioral factors associated with readmission, which might include physical activity levels, sleep habits, and social contacts, could highlight ways to prevent readmissions and empower patients to take a more active role in their recovery.

The project team is collaborating to take a generalizable and scalable approach that holistically looks at patients’ behavior before and after surgery and identifies routines in this behavior. These routines will form the basis of their understanding of the predictive factors for readmissions, particularly while patients are still in the hospital after surgery or other treatments.

Harnessing technology to monitor these and other behavioral risks before surgery, during inpatient recovery, and during the critical transition from hospital to home will advance the field in a number of ways:

  • Reliably assessing and computationally modeling behavioral risks associated with readmissions to improve risk stratification
  • Identifying optimal targets and timing for behavioral intervention to reduce preventable readmissions
  • Providing data that may be helpful and motivating for patients and that could inform clinical decision making to improve quality of care

Researchers

This project is led by Dr. Anind Dey, Dr. Charles M. Geschke, Director of the Human-Computer Interaction Institute at Carnegie Mellon University, and Dr. Carissa Low, Assistant Professor of Medicine and Psychology, Biobehavioral Oncology Program, University of Pittsburgh Cancer Institute.

Detecting Intestinal Activity by Analyzing Gut Sounds

Project Summary

A non-invasive device that analyzes sounds from the intestinal tract could become a powerful new tool to help physicians diagnose and monitor a variety of gastric illnesses, such as acute pancreatitis, bowel obstructions, irritable bowel syndrome, inflammatory bowel disease, and Crohn’s disease.

Carnegie Mellon researchers, collaborating with UPMC gastroenterologists, will be developing, testing, and performing clinical research on a wearable sensor array to detect intestinal sounds – a new vital sign for the “gut.” Its impact could be substantial: In the U.S. alone, digestive diseases afflict 60-70 million people annually with treatment costs totaling more than $100 billion.

Using machine learning techniques, the researchers will develop a means of interpreting the acoustic signals to examine the determinants of gut activity and activity suppression, the ability to identify gastric disorders on the basis of sounds, and the device’s therapeutic potential for enabling gut regulation via biofeedback. The project will also develop classification procedures that use these features to distinguish between the various types of gastrointestinal activity.

Researchers

The research team includes Dr. George Loewenstein, Professor of Economics and Psychology, Department of Social and Decision Sciences and Dr. Ali Momeni, Associate Professor of Art, College of Fine Arts, along with Dr. Rich Stern, Professor Electrical & Computer Engineering, Dr. Max Gsell, Associate Professor, Department of Statistics and Dr. Valerie Ventura, Associate Professor, Department of Statistics.

Healthcare Trails and Care Coordination Using Admissions, Discharges, and Transfers Data

Project Summary

This project is determining if coordinated care decisions could be improved by analyzing and monitoring how patients move through the healthcare system.

They will be focusing on healthcare trails – time-ordered sequences in which a patient obtains services such as dialysis, blood work, or psychological counseling. These trails will be analyzed to identify those that are commonly used by patients with similar conditions and those that most often improve patient conditions. Factors such as a patient’s age, healthcare coverage, and medical condition can affect the flow of these services, and differences in flow can be associated with different patient outcomes.

The goal is to develop, test, and assess algorithms and interfaces for analyzing hospital admissions data and for providing feedback to doctors and caregivers through automated patient tracking and notification systems. By analyzing the timing of admits, discharges, and transfers, the application could help inform care givers about how a patient’s care is being managed and detect when a patient might be at risk because of the healthcare trail they are on.

Researchers

This team is led by Dr. Kathleen M. Carley of the Institute for Software Research and Dr. L. Richard Carley of the Electrical and Computer Engineering Department.

In-Home Movement Therapy Data Collection

Project Summary

A team from Carnegie Mellon, the University of Pittsburgh, and UPMC is working on a project to evaluate the ability of cameras, inertial measurement units, and other sensors, in combination with machine learning (ML) algorithms, to assess patients’ movement therapy exercises in the home. The long-term goal is to increase the quality and efficacy of physical therapy by providing patients with automated, in-home monitoring, near real-time feedback on exercise performance, and feedback to providers when issues arise outside of the PT setting. This will enable providers to prioritize clinic time for patients whose recovery has stalled while avoiding unnecessary appointments for those who are progressing satisfactorily.

Researchers

Leading the team’s machine learning evaluations from Carnegie Mellon’s School of Computer Science are Dr. Jessica Hodgins; Dr. Dan Siewiorek; Dr. Asim Smailagic; and Dr. Andrew Whitford. Dr. Keelan Enseki from the UPMC Center for Rehab Services and Dr. Adam Popchak, from the University of Pittsburgh’s Department of Physical Therapy, are leading the clinical stages of the project.

My Healthy Pregnancy

Project Summary

The costs of preterm births to the healthcare system and society are exceedingly large, and the incidence of preterm births is on the rise despite medical advances. This has created a need to provide reliable, personalized information to pregnant women about how they can reduce their risk of premature births. In response, researchers have created the “MyHealthyPregnancy” smartphone app.

The app applies statistical machine learning techniques to comprehensive pregnancy data sets to improve the app’s patient-specific risk predictions of adverse pregnancy outcomes. It also employs decision science techniques to extend the app to provide post-partum education and behavioral feedback to minimize infant mortality outcomes. The team, which has performed pilot studies of the concept, expects this work will result in a product that can be tailored to both the UPMC health system and developed into an off-the-shelf application for the general population of pregnant women.

Researchers

The project is led by Dr. Hyagriv Simhan of Magee-Women’s Hospital and Drs. Tamar Krishnamurti and Alexander Davis of Carnegie Mellon University.

Phylogenetic Models for Predicting Cancer Progression

Project Summary

Despite screening technologies and public health efforts that have improved the detection of early-stage cancers, methods to reliably predict which of these cancers will progress to more aggressive stages, metastasis, and ultimately patient mortality are lacking.

The project team is working on a suite of software tools that clinicians will use to improve cancer diagnosis and therapeutics based on the molecular signatures of the patient’s tumor genome.

The goal of the project is to develop novel models, algorithms, and software tools to better understand the origin and evolution of tumor cells and how a patient’s tumors are likely to progress. This information would contribute to personalized, precision treatment of cancer.

Researchers

The project is led by Dr. Russell Schwartz, Professor of Biological Sciences and Computational Biology and Dr. Jian Ma, Associate Professor of Computational Biology, both with the School of Computer Science.

Programming Framework for Managing Patient Privacy

Project Summary

As health data is increasingly digitized, the need to protect patient privacy is unprecedented. The Programming Framework for Managing Patient Privacy team is collaborating on an approach to protect patients’ health records and computations involving sensitive patient data from being leaked in a breach.

Project researchers propose a programming model and software framework for managing the privacy of health data. The programming model allows programs to attach privacy policies directly to the data, rather than requiring the programmer to implement the correct privacy checks across code that uses the data. Attaching privacy policies to the data enables programs to be policy-agnostic and to be updated independently of the specification and implementation of privacy policies. The system tracks the flow of data, as well as the policies, so the programmer need not do so. This approach facilitates auditing, as policies may now be centralized and to be implemented only once, instead of as checks across the program. Auditors may also leverage the fact that the framework, rather than the programmer, is now responsible for correctly implementing the checks.

This project is the first step in a long-term plan to improve patient care and promote scientific discovery by allowing sensitive health data to be shared safely. This plan involves 1) applying prior work on policy- agnostic programming for information flow policies in the context of patient health records, 2) extending and combining prior work to support more expressive policies, and 3) building a practical framework that can be used to safely share sensitive data.

Researchers

The project team consists of Dr. Jean Yang, Dr. Matt Fredrikson, and Dr. Jian Ma, from Carnegie Mellon’s School of Computer Science.

Real-Time Tool to Predict Clinical Outcomes After Cardiac Arrest

Project Summary

Over 150,000 Americans are treated in hospitals each year after cardiac arrest, virtually all of whom are initially comatose. Once their hearts are revived, most such patients eventually die in the hospital from brain injury, but a sizable minority will awaken and have a good neurological recovery. With current technology, no sign, symptom, or test result in the first 72 hours after cardiac arrest is sufficient to preclude a favorable recovery. Prognosis often remains uncertain for days or even weeks thereafter. The project team is developing technology that will use advanced signal processing and modeling methods to allow accurate neurological prognostication sooner than currently possible.

Researchers

Project team members are Dr. Daniel Nagin, at Carnegie Mellon University’s Heinz College, and physicians Dr. Jonathan Elmer and Dr. Cliff Callaway from the University of Pittsburgh Medical School.
