EMPLOYMENT HISTORY
Jan 2016 - present

GWW School of Mechanical Engineering, Georgia Tech
As a research faculty, working with Prof. Shannon Yee, I am responsible for identifying, planning, and executing research programs including interfacing with program managers, other engineers in the team and suppliers, and:
(i) As a Co-Principal Investigator for a $2.2 million Department of Energy (DOE) program:
- I am leading the design and construction of an innovative immersion electrothermal probe for accurately measuring thermal conductivity and specific heat of molten salts, up to 800°C, with less than 15% error;
- I created and curate the only thermophysical property database for molten salts, metal alloys, ceramics (up to 1200°C), including the error analysis and the error propagation; and
- I co-initiated the idea, wrote the proposal, budget, and planned the milestones.

(ii) Previously, as a Lead Research Engineer on a $2.4 million DOE program:
- I fabricated a novel dual-stage alkali metal thermoelectric converter (AMTEC) module prototypes and successfully demonstrated the highest practical thermal efficiency of 40.3% for such a system;
- I performed technoeconomic analysis that explore feasibility of AMTEC for distributed CSP system;
- I developed an innovative high-temperature metal-glass brazing to seal beta”-alumina solid electrolytes;
- I led the design and construction of sodium test loop inside Ar glovebox to validate the simulated AMTEC sub-thermal components; and
- I assisted the development of a thermo-electro-chemical system model for the novel dual-stage AMTEC.

(iii) I manage the contracts and reporting requirements for these projects that consist of quarterly reports (~20 pages in length) and end-of-phase/final reports (~100 pages); including preparing effective PowerPoint presentation to the DOE.

(iv) I have recruited and served as supervisor for 1 visiting professor, 3 postdocs, 3 Ph.D. and 3 undergraduate students.
Graduate Research Assistant
Jan 2011 - Dec 2015

Summer 2014

Sustainable Thermal Engineering Laboratory, ASU
I worked with Prof. Patrick Phelan (i) studying thermogalvanic energy transport and energy conversion:
- I investigated the feasibility of incorporating thermogalvanic waste heat recovery systems into automobiles;
- I investigated Seebeck coefficient enhancement of polyelectrolytes (observed up to 75% improvement);
- I theoretically and experimentally investigated the effect of natural convection on power generation of Cu(II)/Cu thermogalvanic cell (observed up to 100% improvement on the maximum power output of the cell); and
- I designed and built thermogalvanic cell apparatuses to investigate the effect of different operational conditions on Seebeck coefficient and power generation of Cu(II)/Cu thermogalvanic cells.

Previously, I (ii) studied thermal energy conversion in nanofluids for direct-absorption solar collectors:
- I investigated volumetric boiling characteristic of the nanofluids that I synthesized, and observed up to 50% more vapors are generated in the nanofluids than in conventional 'base' fluid;
- I synthesized Ag, Cu, Ni, Al, multiwalled carbon nanotubes, and graphite nanofluids; and
- I designed and built infrared (IR) and visible light image/video acquisition systems to complement the existent laser-induced volumetric boiling experiment setup.
Graduate Student Researcher
Aug 2008 - May 2010

Microfluidics Laboratory, USC
I worked with Dr. Tait Pottebaum developing a non-intrusive thermo-microfluidics measurement technique, which can be used to improve lab-on-chip devices, inkjet printer nozzles, and other simultaneous thermometry-velocity measurements:
- I customized a Digital Micro Particle Image Velocimetry algorithm, which was planned to be integrated with the new system, to investigate the flow and driving force on bubbles and droplets in a microchannel with an imposed temperature gradient; and
- I designed and built a unique heater block with 5 embedded mini-thermistors and 12 mini-thermoelectric devices to conduct the micro-thermometry experiments.
Research Assistant
Aug 2006 - Feb 2008

Aero and Gas Dynamics Laboratory, ITB
I worked with Prof. Lavi Zuhal designing and building a Stereoscopic Particle Image Velocimetry system to measure pseudo-3-dimensional instantaneous velocity field:
- I developed a cross-correlation based object tracking algorithm; and
- I presented and successfully defended my Bachelor's Thesis on the subject.
Intern
Summer 2005

PT. Toyota Motor Manufacturing Indonesia, Jakarta, Indonesia
I evaluated the effect of Toyota Original Equipment Manufacturer (OEM) accessory products, which are designed specifically for the Kijang Innova, towards the car’s Drag Coefficient (CD):
- I conducted 2-dimensional Computational Fluid Dynamics (CFD) analysis using FLUENT; and
- I developed 2-dimensional model and grid of Toyota Multi-Purpose Vehicle (MVP), Kijang Innova, from the car’s full-scaled blueprint using the grid/mesh-generation software, GAMBIT.

Project ENGAGES
Project ENGAGES is a high school science education program developed by Georgia Tech in partnership with seven minority-serving public high schools in the City of Atlanta. The student population of all partnering schools is predominantly African-American with a high percentage of students receiving either a free or subsidized lunch. I mentored a student from B.E.S.T. Academy, an all-boys high school, to experience and conduct his own research project in our lab for a whole year, working full-time in the summer and 15 hours per week during the school year, and present his project at a science fair competition.

IEEE Transportation Electrification Community eNewsletter
The IEEE Transportation Electrification Community eNewsletter is a quarterly electronic publication targeted at IEEE TEC members interested in various topics which are related to transportation electrification. I voluntarily joined the Newsletter during its inception and helped start the newsletter publications. I initiated and led a new effort of synthesizing IEEE Distinguished Lecture Series into a series of article for publication in the Newsletter. I managed an international group of editors, and mentoring new editors. I also managed the peer-review process. The IEEE recognized this experience with an invitation and induction to the Eta Kappa Nu (IEEE-HKN) Electrical Engineering Honor Society.
