WunderThink R&D Boston, MA

Feb. 2010 - Present

Consultant

- Conceptualized and designed latching mechanism & gear train in "Belt

locking system" (part of a prototype medical device project) for

WunderThink R&D.

- Created mechanical design of the system, complete with theoretical

calculations, selected standard components based on cost of

manufacturing.

manufacturability, efficiency and durability of components using finite

element analysis, tensile testing & impact testing techniques.

Northeastern University Boston, MA

Jan. 2009 - Dec. 2009

Research Assistant

- Accountable for experimentally verifying the "continuum model used to

determine the frictional interaction between a Carbon Nanotube and

various substrates" by manipulating Carbon Nanotubes on substrates like

Silicon, Silicon dioxide, HOPG, and MICA using the tip of an Atomic Force

Microscope.

- Estimated frictional interaction by comparing the shape of the deformed

Carbon Nanotube with the ideal equilibrium shapes obtained from the

continuum model.

Nantero, Inc. Woburn, MA

May 2008 - Nov. 2008

Graduate Intern

- Directly responsible for design, execution & management of prototype

projects aimed at improving the production process of Carbon Nanotube

solutions.

- Analyzed the outcome of these projects, quantified the amount of

improvement and conducted feasibility studies to assess the need of

replacement of equipment and/or change of process parameters.

- Formulated Standard Operating Procedures (SOPs) for equipment and

processes while maintaining detailed document records and WIP databases

for ongoing projects

- Collaborated with the Materials and Device departments to deliberate on

innovation in existing techniques and addressing current issues.

- Performed Thermo-gravimetric analysis on Carbon Nanotube raw material to

investigate the amount of inorganic impurities.

- Conducted surface treatment of wafers (plasma treatment & wet chemical

etching) in preparation for inspection of Carbon Nanotube solutions

coated on wafer for impurities & defects.

- Characterized Carbon Nanotube raw material coated on silicon wafers

(using AFM, SEM, and Optical Microscopes) and analyzed Carbon Nanotube

films for defects (using techniques like Plasma ashing, Reactive ion

Etching for removal of organic matter on wafers).
