FINDING YOUR WAY...WHEN YOU CAN'T SEE

How can mobile phones help the blind navigate unfamiliar places? An Android app that I've helped develop is showing promise for the future of blind navigation.

MODELING THE EYE WITH A MEMRISTOR

Memristors are often used to model neurons, but can they be used to model other biological systems like the pupil? Take a look at my novel memristive circuit that mimics pupil diameter in the presence of changing illumination.

"OK GOOGLE - I'M LOST"

Indoor navigation can be difficult when you're in a new place. IoT can change that. Enter the Smart Sign - a device that extends the Google Assistant to provide users with custom directions in a building.

CMOS FULL ADDER LAYOUT

How do circuit designers prioritize design parameters like gate sizes and number of stages? Take a look at my CMOS full adder layout that was built with speed in mind.

FIELD AUTOMATED ROUTING MODULE (FARM)

How do farmers make sure they fertilize and plant their fields efficiently? Is there an alternative to complicated GPS units and pricey software? The open-source Android FARM app allows farmers to track their location as they drive their tractor. They can define the width of their path and even the area of their field.

DIJKSTRA'S ALGORITHM IN WINDOWS

Dijkstra's Algorithm is an essential component in modern graph theory. Its purpose: finding the shortest weighted distance between nodes. My C++ implementation and Windows console app make this algorithm very simple to use.

LaTeX TABLES MADE EASY

This online web tool makes it easy to convert your Excel data into a LaTeX table. Just copy your table in Excel and paste it into the text box. Multiple formatting options available.
