Experience
Independent Consultant
Feb 2016 - Jun 2016 (4 months, 1 day)
Worked with a team of biologists, chemists, and other engineers to develop electronics for detecting specific proteins in blood samples. The project involved providing design input, laying out and testing a PCB with many analog input channels, a multiplexing analog to digital conversion scheme, and an embedded micro controller unit.
Acting Engineering Supervisor, Sigma Labs, Inc., Santa Fe, NM
Dec 2015 - Feb 2016 (2 months, 1 day)
Supervised the Sigma Labs, Inc. engineering team from a management perspective. The team consisted of electrical, mechanical, and software engineers.
Lead the team from a perspective of fostering technical innovation by encouraging both independent and team thought and problem solving.
Provided a bridge to senior management while simultaneously advocating for the team members and encouraging their personal and professional growth.
Senior Electrical Engineer, Sigma Labs, Inc., Santa Fe, NM
Jun 2014 - Feb 2016 (1 year, 8 months)
Directed the integration of mechanical and electronic components into sophisticated direct metal laser sintering additive manufacturing machines (metal 3D printers). This required a working knowledge of both mechanical and electrical design best practices combined with an engineering instinct to assemble systems that will function robustly in real world environments.

Measurements of the reduced force coefficients for H2, N2, CO, and CO2 incident upon a solar panel
Phys. Rev. E, vol. 58, no. 1, pp. 492–503, Jul. 1998
The reduced force coefficients were measured for H2, N2, CO, and CO2 incident upon a solar panel array material, SiO2-coated Kapton, Kapton, and Z-93-coated Al. The coefficients were determined by measuring both the magnitude and direction of the force exerted on the surfaces by molecular beams of the gases.
Digital spatial filter made from a SQUID array
IEEE Transactions on Applied Superconductivity, vol. 13, no. 2, pp. 779–782, 2003.
A linear array of high transition temperature SQUID, has been configured to work as digital spatial filters. The SQUID filters can be configured to obtain a desired spatial frequency response. We describe their design using a technique known as Frequency Sampling, which consists of specifying a discrete spatial frequency response for the SQUID array spatial filter.
Weld quality evaluation using a high-temperature SQUID array
IEEE Transactions on Applied Superconductivity, vol. 13, no. 2, pp. 235–238, 2003
This paper presents preliminary data for evaluating weld quality using high-temperature SQUIDs. The SQUIDs are integrated into an instrument known as the SQUID Array Microscope, or SAMi
The National Ignition Facility Neutron Imaging System
Review of Scientific Instruments, vol. 79, no. 10, pp. 10E529–10E529–5, 2008
The National Ignition Facility (NIF) is scheduled to begin deuterium-tritium (DT) shots possibly in the next several years. One of the important diagnostics in understanding capsule behavior and to guide changes in Hohlraum illumination, capsule design, and geometry will be neutron imaging of both the primary 14 MeV neutrons and the lower-energy downscattered neutrons in the 6–13 MeV range
Neutron imaging development for megajoule scale inertial confinement fusion experiments
J. Phys.: Conf. Ser., vol. 112, no. 3, p. 032078, May 2008
Neutron imaging of Inertial Confinement Fusion (ICF) targets is useful for understanding the implosion conditions of deuterium and tritium filled targets at Mega-Joule/Tera-Watt scale laser facilities.
Progress toward the development and testing of source reconstruction methods for NIF neutron imaging
Review of Scientific Instruments, vol. 81, no. 10, pp. 10D311–10D311–3, 2010.
Development of analysis techniques for neutron imaging at the National Ignition Facility is an important and difficult task for the detailed understanding of high-neutron yield inertial confinement fusion implosions.
Investigations into reconstruction techniques for the NIF Neutron Imaging System
J. Phys.: Conf. Ser., vol. 244, no. 3, p. 032051, Aug. 2010
Neutron imaging is currently being developed as a primary diagnostic for inertial fusion studies at the National Ignition Facility (NIF). It is an attractive diagnostic for measuring asymmetries in the burn region and will be able to operate at neutron fluences found during ignition scale implosions.
Modeling the National Ignition Facility neutron imaging system
Review of Scientific Instruments, vol. 81, no. 10, p. 10D335, Oct. 2010.
Numerical modeling of the neutron imaging system for the National Ignition Facility (NIF), forward from calculated target neutron emission to a cameraimage, will guide both the reduction of data and the future development of the system
Performance characteristics of the neutron imaging diagnostic at NIF

A new gated x-ray detector for the Orion laser facility
SPIE Proceedings, 2012, vol. 8505, p. 85050K–85050K–10
Gated X-Ray Detectors (GXD) are considered the work-horse target diagnostic of the laser based inertial confinement fusion (ICF) program. Recently, Los Alamos National Laboratory (LANL) has constructed three new GXDs for the Orion laser facility at the Atomic Weapons Establishment (AWE) in the United Kingdom
The neutron imaging diagnostic at NIF (invited)
Review of Scientific Instruments, vol. 83, no. 10, p. 10D317, Aug. 2012.
A neutron imagingdiagnostic has recently been commissioned at the National Ignition Facility (NIF). This new system is an important diagnostic tool for inertial fusion studies at the NIF for measuring the size and shape of the burning DT plasma during the ignition stage of Inertial Confinement Fusion(ICF) implosions.
Relativistic Transparency Experiments at the Trident Laser.
APS Meeting Abstracts, vol. 1, p. 6009. 2013
With near-diffraction-limited irradiance of 3 × 1020 W/cm2 on target and prelase contrast better than 10-9, we have accessed the regime of relativistic transparency (RT) at the Trident Laser. The goal was to assess electron debris emitted from the target rear surface with phase-contrast imaging (PCI) and current density measurements (hence, the total electron current). Companion diagnostics show whether the experiments are in the target-normal-sheath-acceleration mode or in the RT regime.
