Work Experience

Research associate and postdoctoral scholar at the University of Southern California, Information Sciences Institute (ISI)

- "Tracking Individual Performance with Sensors", Study of job performance and mental health in work environment using physiological signals

- Observational study of users to draw inferences about trolling/aggression triggers in online communities 

  • Data collection, designing survey for labeling and classification of comments in a semi-anonymous social network
  • Applying statistical tools to infer the cause of anti-social behavior and the effect of “anonymous posting features”

Data Scientist– Danaher Labs, Sep 2015 – April 2017 

- Leading the project with a small team of 2-3 data scientists 

- Applying machine learning, statistics and data analysis techniques within Business Intelligence vertical.
  • Customer attrition prediction

- Applying machine learning, statistics and data analysis techniques within Internet of Things (IoT) vertical. 

  • Predict machine failure
  • Anomaly detection in time series
  • Device lifetime prediction 

- Providing an overview of data science and predictive analytics in variety of industries by holding Boot camps for Danaher Corporation employees. At the end of this boot camp, attendees will:
  • Be able to identify the power of data that helps understand voice of customer, provides insight to improve product reliability, and leads to monetization. 

  • Be familiar with several data science techniques backed up by on-site training examples/practice and illustrative use cases. 

  • Appreciate the applications of data science in different industries.
