Building end to end machine learning systems.

-- Designed, implemented, validated, and deployed a new laser system to calibrate astronomical spectrographs used in the search for extra-solar planets.-- Developed software in C to map the pixels of the spectrograph’s camera to the colors emitted by the laser and to transfer that mapping onto the measurements of stellar light.-- Created database software in IgorPro to organize 500GB of calibration data and to facilitate its analysis.-- Built a spectrograph and wrote software in LabVIEW allowing real-time analysis of 50 Mb/s streaming data using multi-core processing that made the most accurate measurements of the Sun to date.-- Advised Harvard Origins of Life Initiative Principle Investigators on pulsed and continuous UV light sources for investigating the synthesis of RNA on pre-biotic Earth.-----------Laser frequency combs for echelle spectrograph wavelength calibrationPrincipal Investigator: Prof. Ronald L.

-- Consulted for Zidisha.org to predict rates of new micro-loan borrowers to their website.-- Extracted Zidisha’s unlogged policy changes from their database.-- Coded in Python and MySQL to perform regression analysis on time series data to generate actionable, interpretable results with clear relationships between policy changes and borrower behavior.-- Generated a report outlining the analysis with visualizations of the data and results available as a blog post at balancingtheload.net.

-- Optimized a two-species noble gas maser for setting limits on new physics beyond the Standard Model that couples to the spin of the neutron.-- Modeled all sources of fluctuations in the system with better than 20% agreement to experimental data over two decades of amplitude and four decades of frequency.-- Improved system robustness and automation such that it could run continuously for months rather than days.
