Received a UNF summer undergraduate teaching grant $7,500 in 2014. Developed a laboratory and a set of experiments to support the teaching of Texas Instruments MSP430 microcontrollers.

The Omnii Sense project, $10K funded by MegaWatt Ventures Competition, sponsored by the U.S. Department of Energy, 2011-2012. The PI's were Jerry Merckel and Chiu Choi.

Co-PI of a project titled “Sensor Arrays for Multiple Applications” funded by the U.S. Army. The project was proposed by the UNF Sensors Group that received a funding of 1.4 million in the period from 2009-2010.

Received a UNF summer undergraduate teaching grant in 2009. The total amount was $7,500. The outcome of the grant was a website of embedded reference designs covering sensors, motors, motor drivers, LCD displays, keypad interfaces, and other embedded electronic circuits. This project was completed in fall 2009.
