Spotlight On: Dmitriy Dligach

Dmitriy Dligach, Associate Professor in the Department of Computer Science in the College of Arts and Sciences at Loyola University Chicago, has been awarded two grants from the National Institute of Health for his research on developing methods for automatic semantic analysis of texts.

The Faculty Spotlight shines this week on Dimitry Dligach, PhD, Associate Professor in the Department of Computer Science in the College of Arts and Sciences at Loyola University Chicago, who was recently awarded two grants from the National Institute of Health (NIH) for his research on developing methods for computational analysis of natural language texts.

 

Dligach works at the intersection of artificial intelligence, machine learning, natural language processing (NLP), and medicine. All of Dligach's current projects have a critical component – representation learning – that is key to their success. Representation learning involves techniques that allow a system to automatically discover representations needed for feature detection or classification from raw data.

 

It is estimated that 80 percent of clinical data today is stored in an unstructured form as text in clinical notes. Within this corpus of text lies a vast amount of valuable information that can be leveraged for phenotyping, pharmacogenomic studies, outcome prediction, and clinical decision support, ultimately improving patient care and reducing healthcare costs. Dligach is currently involved in a number of medical informatics projects that share the goal of facilitating robust and accurate information extraction from electronic health records (EHRs) via NLP and machine-learning algorithms.

 

Dligach’s research program is highly interdisciplinary, resulting in publications in peer-reviewed clinical journals, as well as in more traditional NLP and machine- learning venues. In addition to working closely with Loyola University Medical Center, where he has a joint appointment, Dligach is involved in many active collaborations with major research centers across the country, such as Harvard Medical School.

 

Dligach has published more than 80 peer-reviewed papers in top NLP and medical informatics venues, such as proceedings of the annual meetings of the Association for Computational Linguistics, Journal of Medical Informatics Association, Journal of Biomedical Informatics, and top clinical journals such as Critical Care Medicine. Many of Dligach’s students are co-authors on these publications.

 

Prior to joining Loyola, Dligach was a researcher at Boston Children's Hospital and Harvard Medical School. He received his PhD in computer science from the University of Colorado Boulder, his MS in computer science from the State University of New York at Buffalo, and his BS in computer science from Loyola University Chicago.

 

“Dimitry Dligach’s research and teaching demonstrate the power of interdisciplinary approaches to address important problems and answer human needs,” says Peter J. Schraeder, Dean of the College of Arts and Sciences at Loyola University Chicago. “By bringing cutting edge technology to medical informatics, his work can greatly improve patient care by putting deeper and more comprehensive patient information into the hands of healthcare providers.”
