My research focus is on on big data sets available through electronic health records; health informatics; and developing an efficient and scalable algorithm for variable selection and predictions. I am is interested in examining the association of antibiotics and hemoglobin A1c (HbA1c) with mortality; and the risks to Post-Traumatic Stress Disorder among veterans. I am performing data analyses using databases provided by the Department of Veteran Affairs. My work with the New York University has focused on epidemiology of diseases. I worked on developing an index for mortality calculation based on Na´ve Bayesian Networks, which is used to predict short and long term risk of mortality in ICU patients. Also, using a Veteran Administration data set I conducted a retrospective cohort study to describe clinical characteristics and outcomes associated with Clostridium difficile infection. I also analyzed data provided by National Cancer Institute (NCI-SEER), and mapped codes into Unified Medical Language System (UMLS) identifiers (CUI) and ran a machine learning method on the prepared dataset.
