• An Approach for Deliberate Non-Compliance Detection during Opioid Abuse Surveillance by a Wearable Biosensor.Wearable sensors can be used to monitor opioid use and other key behaviors of interest, and to prompt.
• Performed signal processing on 3D accelerometer and physiological signal BVP to remove motion artifacts. Used low pass filter to remove high frequency noises from the target signal.
• Extracted 36 and 8 statistical time-domain features from accelerometer and BVP respectively.
• Using a personalized weighted random forest classifier (model), we evaluated if a snippet of BVP and accelerometer data received is actually coming from the expected participant or an alternate person.
• Analysis of our classifier shows the viability of this approach, as we were able to detect DNC (or compliance) with over 90% accuracy (AUC ROC curve) within 3 seconds of its occurrence.

• Natural Language Processing (NLP) and Machine Learning The main motivation is to help users/patients understand their clinical report in terms of whether they have any disease or not. These clinical reports are in the.
• Collaborated closely with other team members to plan, design and develop a robust system for determining diseases in EHR.
• Researched and performed Natural Language Processing (NLP) on 199 patients' electronic/clinical health records (EHR) to build word features using lemmatization, stemming, bag-of-words, pos tags, report type, section.
• Applied cTakes, an open NLP system for named entity recognition to get annotated semantic disorders from EHR.
• Achieved 80% precision by implementing ensemble model (Support vector machine -- Hidden Markov Model) for sequential tagging and classification of words as BIO indicating Beginning, Inside or Outside of disorders.

• Education Data Mining. The goal of this research is to increase the effectiveness of education system across USA in real time and to help teachers adopt efficient tools and methods to revolutionize the learning.
• Education data mining with focus on skill decomposition with randomized controlled experiments. Introduced a novel way to determine sub-skills using k-mean clustering with silhouette coefficient.
• Performed hypothesis test using t-statistic and p-value (0.05) to determine the significance between templates of each problem set. It indicates importance of relative order of solving a sub skill and this order makes.
• Estimated students' performances through their current knowledge state using conditional probability based Hidden Markov Model.
