• SDET II Specializing in Mathematical Projects

  • Jun 2007 - Jan 2015

  Microsoft Solver Foundation (MSF) Tested MSF, a Mathematical Optimization API, for mathematical correctness and usability. The MSF team was the recipient of Visual Studio’s 2010 Lighthouse award. The testing included Optimization solvers for Linear Programming, Quadratic Programming, Stochastic Programming, Nonlinear Programming, Conic Programming, and Constraint Programming. Played an integral role in releasing two major releases and four minor releases of MSF. Wrote a program using MSF to optimize and individual’s schedule, which was released as a sample with the code installation. Codified MSF’s testing standards by documenting the test framework and approach. Made contributions to the MSF blog and responded to customer feedback. Worked as de-facto Release Manager of Solver Foundation version 2.2 Microsoft Technical Computing Tested the numerical accuracy of statistics functions for the Technical Computing project, designed to assist mathematical modeling and computation. The numeric libraries were later released as Microsoft Cloud Numerics. Built a framework for testing the accuracy of functions against established numeric packages, with error tolerance determined by the errors inherent in IEEE floating point numbers. Corrected for the mistakes in the established packages to improve the accuracy of Microsoft’s numeric functions. Assisted a newly acquired group in Boston to acclimate to Microsoft’s standards. Researched, proposed, and assisted in the adoption of the test harness and in promoting testing standards. Coauthored MSDN Magazine article on Testing Numerical Functions in Microsoft Cloud Numerics. Microsoft Data Lab Tested the accuracy of Machine Learning (ML) algorithms against the results of established ML packages. Created a test framework for ML using Cross-Validation, generalizable to any classification algorithm.

Clearsight Systems

• Software Development

• Senior Mathematician

  • Feb 2001 - Oct 2006

  • Participated in the development and implementation of state-of-the-art generic architecture and software libraries for real-time and online business applications. The technology focuses on automating decisions that minimize business criteria. • Translated practical business problems into mathematical functions suitable for optimization algorithms. These business projects include personnel and task scheduling and real time financial trading. • Prototyped algorithms in Matlab and Maple targeted to optimize complex, multi-dimensional functions. • Implemented the Clearsight Forecaster, an algorithm which predicts stock prices up to ten minutes into the future, in Matlab. Also implemented the Clearsight Controller, a companion algorithm which uses those predicted stock prices and an effective trading strategy to optimize stock trading decisions. Show less

• Research Assistant

  • Sep 1994 - Dec 2000

  • Wrote dissertation on the Madden-Julian Oscillation (MJO), a tropospheric, tropical wave pattern of period 30-60 days that has an indirect connection with the El-Nino Southern Oscillation. • Pursued the hypothesis that friction in the lowest layers of the troposphere (the boundary layer) amplifies the MJO. Formulated a simple model of tropospheric dynamics using conservation of mass, momentum, and energy. Concluded that boundary layer friction was a partial explanation for the prominence of the MJO. • Presented talk entitled “Frictional Feedback on Large-Scale Equatorially Trapped Waves” at the Conference of Hurricanes and Tropical Meteorology in June 2000.

• Research Assistant

  • Jun 1992 - Aug 1992

  • Worked at Observatory which had three radiotelescopes – one for space exploration, and two for atmospheric studies. • Analyzed data for the Lower Thermosphere Coupling Study (LTCS-2, Dec. 5-10, 1988) and LTCS-6 (Dec. 4-10, 1991) data sets. The LTCS campaigns were coordinated studies regarding the coupling of the mesosphere with the thermosphere, with data collected a various locations. • Analysis involved Fourier decomposition of temperature and wind data into fluctuations of various frequencies, thereby isolating daily and semi-daily cycles. • Presented the results of the LTCS analysis in June 1992 at the National Center for Atmospheric Research (NCAR) and gave talk on data analysis. A poster paper based on the same analysis was given by supervisors at the same conference a year later. Show less
