My current programming focus is on control system design, data management, and data analysis. I previously built and usability-tested a database-driven website for the University of Michigan Physics Demonstration Lab. Here are a selection of programming projects I've completed.

Hg Vapor Cell, Fiber Seed Laser, Fiber Laser Amplifier, Single-pass PPMgO:SLT SHG, Wavelength-meter, High Quantum Efficiency Photodetector, Gated photon counting (SRS SR400), PID controller, Table-top optics and fiber optics, Waveform generators, Oscilliscopes, Kitchen sink. |
Description | This experiment required interfacing many equipment systems to perform the measurement. Most data-aquisition was autonomous once the experiment was launched creating a data-log file with concurrent reports on photon signal, laser frequency, system temperatures, and laser powers. This apparatus required TTL, RS-232, USB, and Network control. |
Examples | Experiment Code - DAQ - MatLab (.m) LoC: 331 Once the hardware is initialized, this experiment code iterates indefinitely (until GUI Stop is pressed) and appends data run results to the data set. This experimental loop allows data acquisition and synchronization between three autonomous expermeintal systems, a wavelength meter, a photon counter, and an oscilloscope. Analysis Code - MatLab (.m) LoC: 604 This code analyzes and reports on the data taken in a given Hg experiment run. It can run concurrently with the experiment to permit live monitoring of the experiment. |

Tech | VB.NET, ASP.NET, SQL, HTML, CSS |
More: | DemoLab Website User Documentation |
Description | This website served as a catalog of the DemoLab's demonstrations, experiments, and equipment. It was also
an ordering site for instructors, and maintained an agenda of instructor orders for demonstrations and teaching technologies. It
allowed instructors to review past semesters' orders and re-order in bulk. It also kept a dashboard of unavailable demonstrations and
demolab projects. After I left the DemoLab in 2008 it lost all support, however it continued to be the portal for the lab and instructors through 2012!
The university migrated the site to a new platform in 2012 so it could receive university tech support. I'm proud that I gave the site
enough structural integrity that it could fly solo for years. References available. |

Tech | MatLab, HTML |
MathWorks: | Attributed Plot Html |
Example HTML: | Clock Uncertainties An attributed source for current state-of-the-art atomic clocks is why I wrote this program. This connects a plot of clock uncertainties with each data point's respective source. Race Temps This is a generic example of the program's function which plots marathon finish time with respect to race day temperature. |

File: | Find Next Ascent |
Description | A terminal game that accepts a current odometer reading (6-digits) and provides the next ascending sequence. For example, an input of 000480 has a next ascender of 012345. |

Tech | Adobe Illustrator and Photoshop |
Examples: | Hg Clock - Optics Table Layout Tripartite Entanglement - Animated GIF Tripartite Entanglement - Poster |
Description | I use Illustrator to graphically represent the underlying physics and systems I'm presenting. I utilize true to scale information in my graphics where possible to enrich the presentations. |
