Over the course of my academic career, I have had the priveledge to participate in academic research at some of the most prestigious research universities in the world. The research has been on a variety of topics including MEMS, Carbon Nanotubes, Flexible Electronics, Medical Devices and Liquid Interface interactions. The material below gives a brief description of my research as well as any papers or presentations I have produced on them. Although my interests do not currently lie in labratory research, my experience was significant enough to deserve recognition.

Research Experience

Summer 2008

RWTH - Aachen University in Aachen, Germany
UROP (Undergraduate Research Opportunties Program)

"Micro check valve fabricated by ultrasonic molding"

Designed a micro check valve using Pro/Engineer and created an aluminum die tool according to the design. Using the die tool and an ultra-sonic hot embossing machine, polymer micro-structures were created. Sets of polymer micro-structures were fabricated and assembled to create a micro check valve. The performance of the valve was tested.

"Liquid-Air surface interactions"

Tested and attempted to measure surface deflections based on liquid-air surface tension interactions.

Summer 2007

University of Pennsylvania in Philadelphia, PA
SUNFEST (Summer Undergraduate Fellowship in Sensor Technologies)

"Pediatric Dynamometer"

Designed the structure of a device to accurately deflect piezoelectric film within the sole of a shoe. The deflection of the piezoelectric film sends a signal to a device inside the shoe that records and stores this data. The data can be retrieved for an analysis of the patient's physical activity.

Summer 2006

Georgia Institute of Technology in Altanta, GA
MDITR (Material Devices for Information Technology Research)

"Investigating Thin Films of Carbon Nanotubes for Potential Electrode Applications"

Thin films of carbon nanotubes were created using vacuum deposition. In order to gauge potential for use in photovoltaics and other electronics, sheet resistance and transparency were measured. Carbon nanotubes remain conductive in deflection making flexible electronics a possibility in the future.
