Hong Yu, PhD (Principal Investigator) Professor and Principal Investigator UMMS BioNLP Group, Dept of Quantitative Health Sciences, University of Massachusetts Medical School Worcester; Adjunct Professor, School of Computer Science, University of Massachusetts Amherst; Research Health Scientist, VA Central Western Massachusetts.
I am an elected fellow of the American College of Medical Informatics. I received PhD from the Department of Biomedical Informatics at Columbia University. My research focuses on information retrieval and natural language processing and their applications to the biomedical and healthcare domain. AskHERMES is one of the few online systems that provide answers to biomedical questions. NoteAid is a system that translates electronic medical record (EMR) notes to lay language comprehensible to patients. We also mine data from EMRs for healthcare outcome studies. |

Jesse Lingeman Research Assistant, School of Computer Science, University of Massachusetts Amherst
I am a Ph.D. student in Computer Science at the University of Massachusetts Amherst. I am working with Prof. Hong Yu in the BioNLP lab. My research interests focus primarily on using machine learning to provide insights into the world around us. One of my current projects is exploring how the authors of academic publications behave, and what factors decide whether or not they work together. This is done using a time series model that explicitly models how factors relating to both an author's publications and to the network of coauthors surrounding them are changing over time. Previously, I obtained my MS in Computer Science at New York University with Prof. Dennis Shasha, using time series models to infer gene-gene interactions from gene expression data. My masters thesis was turned into an instructional textbook for beginning bioinformaticists on how to do gene network inference, and provides an overview of many state-of-art algorithms and techniques along with simulated performance examples. During that time I also worked with Prof. Karen Adolph in the Developmental Psychology Dept, studying how infants' and non-human primates' motor skills evolve while they are first learning them. I also was lead developer on the open source data annotation program Datavyu. Before that I obtained my BA in Political Science from Western Michigan University, focusing primarily on game theory and Constitutional law. |

Jiaping Zheng Research Assistant, School of Computer Science, University of Massachusetts Amherst
I am a Ph.D. student at University of Massachusetts, Amherst. I'm working with Prof. Hong Yu. I received my Bachelor's degree from Nankai University and Master's degree from University of Minnesota. My research interests include natural language processing, information extraction, and medical informatics. My projects are: Clinical Note Aid. Providing clinical notes to patients can improve health understanding and lead to better healthcare outcome. However, the language in the clinical notes presents a challenge to the patients' comprehension. We aim to lower the barrier by providing short and easier-to-understand explanations and educational resources relevant to the clinical notes. Discovering gaps between consumer health resources. Consumer health resources created by experts may not need the demand of the average patient. We examine online users' questions and compare them to expert curated knowledge resources. This can help guide the creation of health knowledge sources and better allocate resources to the areas that consumers are interested in. |

Abhyuday Narayan Jagannatha Research Assistant, School of Computer Science, University of Massachusetts Amherst
I am an MS/Ph.D. Student at UMass Amherst CS. I am currently working with Prof Hong Yu in UMass BioNLP group. I am a B.Tech in Electrical Engineering from Indian Institute of Technology, Roorkee, India. And I briefly worked at Samsung before joining UMass Amherst Computer Science. My work primarily involves using mathematical tools to model and understand text. To this end, I mainly work with approaches borrowed from Machine Learning and Optimization. Some of the current projects that I am involved in are "Simplification of EMR text using Machine Translation without using a parallel corpus", and "Adverse Drug event detection". Automated Simplification of Medical Narratives through machine translation is traditionally done using a parallel corpus of complex to simple sentences. But creation of such a parallel corpus is very expensive. This is why most efforts which work on this approach use a relatively small corpus. In our work we try to replace the need for a parallel corpus by leveraging upon the regularity of the language we are using. In our Adverse drug event project, we try to build pharmacovigilance tools which work on raw unstructured text from Medical Narratives. The goal is to have a system in place, which can detect events of Adverse drug event and then aggregate them over a large dataset to achieve meaningful information about the adverse reactions. |
