Work Experience: 

UberMedia Senior Data Scientist, March 2016 - Current.
  • Build data products such as foot-traffic patterns to understand the popularity of different hot spots.
  • Maintain and develop the backend, ad-serving optimization engine.
  • Build ad-serving audiences.

Headspace Senior Data Scientist, October 2015 - February 2016.
  • Provide strategic and thought leadership in the areas of analytics and data science to help Headspace better understand her customers, reduce churn, increase engagement, and improve the product.

TrueCar Senior Data Scientist, December, 2014 - September 2015.
  • Led a team of data scientists and data engineers to build a product that provides hyper-localized pricing guidance for car dealers, leveraging vast amount of clickstream and business data.
  • Served as the main architect of the data pipeline, partitioning the project into smaller, meaningful sub-modules that allow concurrent work to meet tight business deadline.
  • Combined my deep understanding of statistical and programming concepts to amplify the skills of the talented Ph.D. trained data scientists and engineers 

TrueCar Data Scientist, February, 2013 - November 2014.
  • Evaluate and improve the performance of Search Engine Marketing campaigns with $100K/month budget.
  • Develop algorithm for calculating the cost of car ownership.
  • Evaluate the use of business intelligence software to unify the various data channels to gain insights on the data.

USC Posdoctoral Scholar in Economics, March, 2011- February, 2013.
  • Researching affects of monetary and non-monetary incentives in motivating people to exert effort in an individual and team settings. 
  • Managing a research lab and facilitate technical projects between the IT department, the Economics faculty, and software programming consultants. One notable project is integrating Biometric hardware with existing Java based software for conducting economics experiments. 
  • Supervising and advising Ph.D. students in implementing economic experiments to understand how people respond to incentives. 

Caltech William D. Hacker Lab Programmer, 1999-2004.
  • Worked as the lead programmer in creating a web-based financial market to test finance and economics models of individual decision making. Designed, tested, implemented and maintained the software system. The front-end of the system was built with PHP. The back-end of the system used MySQL for data storage and interfaced with a commercial linear programming software package that solved linear programming problems. 
  • Implemented a novel pricing algorithm in Python. It was one of the candidate algorithms for the Google IPO. The goal was to provide a leveled field for small investors amidst large institutional investment funds. 

Skills:

Programming 
  • Data Processing Toolkit: Python Pandas, SAS.
  • Statistical Analysis Toolkit: scikit-learn, pystats, stata.
  • Business Intelligence Tools: Tableau.
  • Implement web-based programs in Python, PHP, and MySQL. 
  • Literate in JAVA and C/C++. 
  • Use Mathematica’s functional programming language to automate search of numerical solutions to nonlinear differential equations. 
  • Use Matlab to implement statistical estimators. 
  • Use FICO Express, a specialized optimization programming software library, to solve integer and continuous linear programming problems.

Data Analysis/ Experimental Design
  • Design and conduct experiments to understand people’s strategic response to monetary and non-monetary incentives. 
  • Perform data collection, analysis and statistical testing from data gathered in the lab and on the web. 
  • Conduct extensive literature review to identify different models of decision making models. 

Research Interests:
  • Market Design 
  • Electronic Commerce 
  • Online Communities 
  • Experimental and Behavioral Economics

Teaching Experience:

University of Southern California
1. Political Economy of Institutions: Social Networks (Econ. 330). Fall 2011.
I taught undergraduate students foundational concepts from Economics, Computer Science, and Sociology that help them understand the forces that drive social network formation and other network dynamic. Came up with innovative exercises to teach the underlying technology such as online advertisement.


University of Michigan
2. Networked Computing (SI 502). Fall 2009, Fall 2010.
I taught masters students how to use the Python computer language to do text processing, write simple client-server programs, and learn Internet protocols such as http and TCP/IP.

3. Online Communities (SI 684). Winter 2008.
I taught master students social design principles and features to start, grow, and sustain online communities. I illustrated those principles through specific online communities such as Foursquare. 

4. Information in Social Systems (SI 500). Fall 2007.
I taught master students a variety of theoretical models of information.
