Karl Twelker work experience

A career timeline built from the work history available for this profile.

Senior Member Of Technical Staff

Current

Cambridge, Massachusetts, United States

Designed and implemented a testing protocol to bring cutting edge inertial MEMS sensors and LiDAR sensors. Analyzed test results and communicated to design and fabrication teams to fuel development. Developed models of device function to inform testing and drive the sensor development.

Jul 2019 - Present

Staff Scientist

Watertown, Ma

R&D for next generation wireless power, development of upcoming consumer electronics, data analysis. Development and testing of new designs, materials, and technologies related to wireless power. Managed interns working on cutting edge research projects.

Mar 2015 - Jul 2019

Graduate Student

Stanford, Ca

Experimental R&D for the EXO experiment:Designed and built a device to test barium ion extraction from liquid xenon, including thevacuum vessel, cryogenic cooling, xenon gas delivery, computer control, and ion optics.Simulated the time-of-flight spectrometer using SIMION to ensure the very high ion transport efficiency required.Built a resonant laser photoionization system to provide high-efficiency, high-selectivity re-ionization of barium.Instrumented the system to read out pressures, temperatures, photodiodes and ion detectors using LabVIEW.Co-developed a radionuclide-driven single-ion barium source for use in barium tagging R&D, which has been used in this system as well as systems testing barium tagging from gaseous xenon detectors. Designed a second source using spontaneous fissions of Californium-252 to produce barium ions in liquid xenon.Wrote analysis scripts using Python to interpret data from the experiment and develop newsurface preparations and designs.Mentored a younger graduate student to become an intellectual contributor on this project.Presented this work at TIPP 2011 and TAUP 2013.Helped construct and commission the EXO-200 experiment.

Sep 2007 - Sep 2014

Summer Intern

Livermore, Ca

I helped assemble the Axion Dark Matter eXperiment (ADMX). In constructing aspects of the experiment, I was responsible for assembling pieces of the experiment and testing functionality. ADMX has successfully probed some axion masses.

Jun 2006 - Sep 2006

Summer Intern

Livermore, Ca

Hydrodynamic simulations of inertial confinement fusion are necessary for understanding the results of the National Ignition Facility. My simulations focused on understanding the inertial fusion and simulating imaging techniques to be used.

Jun 2005 - Sep 2005

Employee

Transparent Devices

Juneau, Ak

I helped build science education apparatus in a small garage business environment. The devices I built are sold through science education supply catalogs to middle schools and high schools all over the US. My responsibilities included machining components, assembling apparatus, packing, shipping, and improving the shop space. When new products were developed by the company head---a former high school science teacher---I helped assess whether or not they were good teaching tools.
