- Helped build and distribute CVM-H 11.9.1 (includes some bug fixes for cells without data)
- Registered new CVM-SI with UCVM to allow queries in it
- Generated Vs, Vp profiles for CVM-H 11.9.1, CVM-SI, and CVM-S using Viz-CVM
- Wrote a script to make plotting velocity profiles (including comparison ones such as this) quick and easy
- Ran the CVM evaluation component of CVM-T manually on Kraken
    - Involved running AWP-ODC for wave propagation simulation
    - Generating mesh from CVM-H 11.9.1 and CVM-SI
    - Running post-completion scripts back on SCEC servers
    - Results for CVM-H 11.9.1 here (note this is a temporary location)
- Helped diagnose and troubleshoot source of order dependency error in CVM-S Fortran code

    - Can graphically select sites or select them via name/row for each study
    - Dynamically updates and generates data products based off of the latest available data
    - Can retrieve peak amplitude data as well as generate up to the second hazard maps
    - Integrated into OpenSHA for hazard map generation

    - Useful for Rob's wcc_rotate code
- Expanded upon that script to automate the process for the CyberShake PBR Study

E-trees

- Used ecoalesce and ecompact successfully to make e-tree sizes more manageable
- Worked with Ricardo to deliver those to him
- Wrote description of configuration parameters for UCVM etree extraction

ShakeOut work

- Created registration, stats, and login from scratch
    - "Universal system" consolidated approximately 100 PHP files into about 15-20
