Michael Grasso - Research


Research Interests

The focus on my research is on computational systems that expand the scope of clinical medicine, have a strong theoretical basis in computer science, and are of strategic importance to the University of Maryland Medical Center. My current research includes patient safety and the quality of emergency medical care, suicide and mental health issues in emergency medicine, and big data analytics applied to chronic diseases.

Current Research Projects

  • Knowledge Representation and Reasoning with Big Data - I am developing new methods for knowledge representation and reasoning that are optimized for very large clinical repositories, and which can be correlated with genomic and environmental data. My specific approach is to enhance machine learning algorithms with semantic analysis, domain information, and deep learning. My clinical focus is on coronary artery disease, diabetes, rheumatoid arthritis, chronic kidney disease, chronic pain, addiction, and mental illness. This work will lead to new approaches to quantify clinical risk and enable clinical decision support. It can be applied to disease prediction, critical event prediction, and treatment efficacy prediction. I am currently working with the national clinical repository from the Veterans Health Administration, which contains data on more than 35 million patients from roughly 150 medical centers and 800 outpatient clinics, and which I am augmenting with clinical data from several other sources.

  • Patient Safety and Quality Measures in Emergency Medicine - Patient safety and quality is one of the nation's most important health care challenges. The widely-cited report by the Institute of Medicine estimates that as many as 44,000 to 98,000 people die in U.S. hospitals each year as the result of lapses in patient safety. This is especially important in the emergency department, where health care teams are challenged to rapidly diagnose and treat multiple patients, some of whom present with potentially life-threatening illness. I am conducting research in resource utilitzation and recidivism in emergency medicine, with a focus on co-morbidities, key risk factors, adverse drug events, chronic pain, suicidality, addiction, utilization patterns, and clinical workflow.

  • Computer-Aided Risk Assessment for Suicide, Mental Illness, and Addiction - Suicide is a significant and preventable public health problem, and the tenth leading cause of death in the U.S. In addition, war veterans have a higher risk of suicide, due to a combination of war-related mental illness and physical health problems. While certain known risk factors exist, such as mental illness and addiction, suicidal behavior is complex and often hard to predict. I am developing new computation approaches for risk assessment for suicide surveillance, mental illness, and addiction. This includes the development of a risk ontology along with a set of risk indicators that will be validated through an analysis of clinical, environmental, and genomic data.
