Charlie Sanabria's Carrer Mission Statement
My carreer mission statement

I believe science is absolutely necessary for the advancement of society, and I’m passionately driven towards initiatives that expand human capabilities. Throughout my career I have consciously involved myself in major scientific R&D projects such as ITER and the Large Hadron Collider—learning a great deal about what it takes to carry out international collaborations. I am currently involved in research initiatives that aim to upgrade the Large Hadron Collider, a project that will allow humans to delve deeper into the secrets of matter.

Additionally, I’m always on the lookout to disseminate and popularize science and technology through writings, seminars, social media, etc.

Charlie Sanabria's Research experience
Research experience

1 - Institution: Lawrence Berkeley National Laboratory.

    Position: Postdoctoral Researcher.
    Dates of employment: November 2017 – Present.
    Description of duties and accomplishments:
    Cable task deputy leader of the Accelerator Upgrade Program (AUP) aimed to upgrade the LHC magnets.
    Responsible for the insulation process of over a hundred superconducting AUP cables.
    Led the development of a cryogenic resistivity measurement system used to monitor cable quality.

2 - Institution: The Applied Superconductivity Center at the National High Magnetic Field Laboratory.

    Position: PhD candidate Research Assistant (RA).
    Dates of employment: July 2014 – October 2017.
    Description of duties and accomplishments:
    Under a grant provided by the US Department of Energy my team was to improve the wire technology for the future upgrade of the Large Hadron Collider (LHC).
    My metallographic characterization and microscopy led to an improved heat treatment, and a 28% increase of the critical current density of the wires. (watch presentation here).
    Co-author of a provisional patent application for a new wire design, and first author of a provisional patent application for a heat treatment process.

3 - Institution: Oxford Superconducting Technology (OST), now Bruker.

    Position: Visiting scientist.
    Dates of employment: April 2014 – July 2014.
    Description of duties and accomplishments:
    Performed exploratory metallography and image analysis of OST’s wire production.
    My diagnosis led to a process improvement that increased the magnetic stability of the wires by 30%.
    Supervisor:

    Michael Field


4 - Institution: The Applied Superconductivity Center at the National High Magnetic Field Laboratory.

    Position: Graduate Research Assistant (RA).
    Dates of employment: May 2011 – April 2014.
    Description of duties and accomplishments:
    As part of the ITER crash R&D program (aka the ‘dream team’) our responsibility was to understand the mechanical failure of the ITER conductor prototypes.
    My analysis reinforced our understanding of the mechanical integrity of the ‘short twist pitch’ approach taken by ITER on its Cable‑in‑conduit conductors.
    Published seven scientific journals and gave eight talks at international conferences.
