Work Experience
Lead Developer @ Global Dressage Analytics
Feb. 2011 - Present
Responsible for the engineering aspects of developing a web-based analytics toolkit for dressage athletes, judges, and trainers.
Contributions
Designed the architecture for the web application from the ground up
Made new visualizations (based on Javascript) to quickly communicate the results of the analysis to the user
Developed the analysis algorithms to reduce large score data sets (several million scores) into performance parameters that can be easily understood by the user
Implemented a predictive analysis to allow users to project their performance to some time in the future
Helped create the frontend for the web application (html/javascript/css)
Designed and implemented an asynchronous precalculation and caching mechanism to increase performance in the case where an analysis that a user may wish to view takes more than a few seconds
dressageanalytics.com is a web application which allows atheletes who participate in the equestrian sport of dressage
to track their progress, predict their future performance, get training suggestions, and compare their performance with that
of their peers.
Software Engineer (Contractor) @ University of Tennessee
Dec. 2011 - March 2012
Designed software for interacting with the Pixel Luminosity Telescope, a next-generation particle tracking experiment based on monocrystalline diamond detectors.
Contributions
Created a web-based user interface (based on Django) to provide operators with a simple-to-use tool to run the powerup routines, calibrations, and data runs
Made python bindings for the existing C++ infrastructure (which I also built)
Trained a new graduate student on how to run and develop the web-based user interface that I made
The Pixel Luminosity Telescope (PLT) is a next-generation diamond detector which uses the same complex and highly advanced readout electronics as the
Compact Muon Solenoid's (CMS) Pixel Detector System. Operating the control software by hand is difficult for someone who has less than a few years
of experience with the detector. Therefore, it was necessary to create a user interface which is easy enough for anyone to use to operate the system, log its state at any given time,
and do quality assurance on the data that comes out of the detector. I was commissioned to design and implement this UI using web-based tools.
Lead Developer (Contractor) @ La Casa Del Sol
April 2010 - Oct. 2010
Developed web presence and web application for a real estate business based in Barcelona, Spain.
Contributions
Developed a Joomla! plugin which allowed La Casa del Sol's employees to maintain and display a list of apartments which they represented
Implemented the internationalization infrastructure, which supported English, Spanish, and Russian
Created a pure javascript slideshow plugin which integrated layers of static navigation
La Casa del Sol (unfortunately now out of business due to the owner having to leave Barcelona) was a real estate business which
helped connect prospective buyers/renters to condos/apartments located in Barcelona, Spain. They relied on a web application
which I designed that allowed them to make a searchable list of apartments which they represented.
Programmer/Research Assistant @ University of Tennessee
Aug. 2008 - Dec. 2011
Designed control, instrument driver, visualization, and analysis software for the Pixel Luminosity Telescope, a next-generation particle tracking experiment based on monocrystalline diamond detectors.
Contributions
Designed and implemented calibration algorithms for intelligently tuning instrument operational parameters
Created and implemented the data acquisition framework
Managed system tests (~15 people present) in particle beams to measure fundamental parameters of diamond detectors, such as resolution, charge collection depth, efficiency, and sensor lifetime
Designed the web-based detector monitoring framework for the CMS Beam and Radiation Monitoring (BRM) group, which was the first place where beam was seen in CMS
Analyzed the data taken by a diamond-based monitoring device called the Beam Conditions Monitor 1L (BCM1L) to measure important parameters such as the minimum sensitivity, which were in turn used to set beam abort conditions for CMS
Diamond is a radiation-hard and heat-tolerant material, which makes it useful as sensor material in harsh environments such as
those found in modern particle accelerator interaction regions. I have helped to quantify properties such as spatial resolution,
charge collection depth, and the Lorentz Angle in lab-grown
diamonds to establish their suitability for different applications.
The Zurich Beam Telescope is a silicon micostrip tracker capable of delivering 1 micrometer resolution for
localizing charged particles which pass through it. This high resolution is useful for studing the characteristics
of many other particle detectors, which may be inserted inside of the assembly to provide detailed studies of
the spatial behavior of the instrument.
The Pixel Luminosity Telescope (PLT) is a next-generation diamond detector which uses the same complex and highly advanced readout electronics as the
Compact Muon Solenoid's (CMS) Pixel Detector System. Calibrating and operating the system is a complex exercise, and I was commissioned to help design
the software and firmware to deal with it.
The BRM Data Logging and Analysis Framework takes data from a number of sources--my GUTS framework, a CORBA-based CERN standard protocol called CMW, and another CERN-standard protocol called DIP--and
logs the data to files, which are nightly archived to deep storage through CERN's heirarchial storage solution called CASTOR. After the data is archived, it is analyzed using a
ROOT-based data analysis package which can extract various instrument performance parameters.
Research Assistant @ University of Tennessee
Oct. 2006 - Aug. 2008
Developed software and implemented high performance computing infrastructure for both the University of Tennessee Physics Department and the Compact Muon Solenoid experiment at the Large Hadron Collider at CERN.
Contributions
Implemented a distributed file system (Lustre) on a Beowulf cluster used for physics analyses
Created the real-time instrument monitoring framework for the CMS BRM group
Developed a software package for transferring data from instruments to displays over the network in real-time
Developed a scalable mechanism for monitoring errors in the 66 million pixel channels in the CMS Pixel detector
DIP-Cache is a realtime data caching server which accepts data coming from any source that publishes its data through the Data Interchange Protocol (a CERN standard communication protocol).
In addition to simply caching data as it comes in, it responds to queries which allow the user to limit the data length, select the most recent time stamp, choose a specific instrument ID, etc.
The Beam and Radition Monitoring (BRM) realtime display framework takes the highly important radiation monitoring data which comes from the BRM subsystems and displays
it in such a way that shifters can monitor it 24/7 to make machine-safety decisions based upon the displayed data.
GUTS is a library, used by CERN's Compact Muon Solenoid Experiment, which serializes arbitrary java objects and transfers them to a list of connected clients for processing.
The primary use of this library is to transfer data between two distinct networks: CERN's Large Hadron Collider Machine Network, and the Compact Muon Solenoid network.
This library works only one way--i.e., the protocol accepts no direct feedback from the clients--in order to satisfy the strict security standards required by CERN management
for software which bridges the two networks.
Lab Assistant @ University of Tennessee
Dec. 2005 - Oct. 2006
Developed software applications to run the equipment used by students in physics lab classes.
Contributions
Created a hardware/software solution for measuring and visualizing electric fields on conducting paper
Implemented control software for controlling an X-ray machine for use in a Bragg diffraction experiment
Developed control software to control a Cesium heatpipe experiment
Made an application for measuring Compton scattering by controlling a stepper motor, radiation detector, and a gamma source
I was commissioned to write a laboratory exercise for use in the University of Tennessee Modern Physics Laboratory which could teach
students how to use LabVIEW and MATLAB together to interact with and analyze lab instrumentation.
