Experiences

Project Manager

Powder Metallurgical Research Laboratory, University of Utah Summer 2014 to Present

Managed the DOE and the Army projects on development of nanocrystalline tungsten

alloys.

Improved process methods which decreased defect rate 5 times, increased maximum sample

dimension 300% and sintered density 3%.

Reduced furnace process time 55% by introducing binderless compaction and sintering process.

Developed new tungsten alloys using a combined process of foundry and powder metallurgy.

Designed plasma facing W discs for Sandia National Laboratory with superior properties than

PLANSEE and ALMT samples.

Involved in Army proposal “Manufacturing of Nanocrystalline Tungsten for Army Application”

as the key personal of product and process development. ($2.5 million grant, proposal approved.)

Investigated the influence of alloy additive, powder compaction and sintering on the

densification, microstructure and mechanical behavior of W alloys.

Post-Doctoral Research Associate

Powder Metallurgy Research Laboratory, University of Utah Summer 2012 to Summer 2014

functional temperature 300 C, increased the efficiency of reaction 10 times.

Established a national collaboration team including researchers from 3 national labs, 3

universities and 1 industrial research lab.

Conducted synchrotron and neutron experiments at Argonne National Laboratory and Oak Ridge

National Laboratory.

Designed high-temperature-high-pressure test furnace for Argonne National Laboratory.

Awarded over 400 hours instrument time (worth ~$130,000) in national labs as PI in 10

proposals.

Graduate Research Assistant

Magnetic Material Laboratory, University of Utah Fall 2009 to Summer 2012

Responsible for sample process and characterization in NSF project on ferrous

magnetostriction materials.
