Area of Interest

In Electrical and Computer Engineering my area of focus is in embedded systems design and implementation. Through internships in various companies like Siemens, IBM, Reiz electrocontrols and Qualcomm, I have gained domain knowledge of building automation systems, lighting control systems and writing drivers for linux based systems. Also via class exercises have learned about elevators and automotive control networks. I plan to go further and explore dependable and safety critical embedded systems and sensor networks.
I have also taken a course on real time embedded systems where I worked on the android operating system. I added real time functionality and effective power saving algorithms to the existing operating system on the OMAP based Motorola Droid 2 phone.

On the economics/business front, my interests lie in the behavior of agents in different economic situations and the movement of markets to an economic equilibrium.
Under standing the behavior of economic agents in imperative to determine what influences the formation and clearance of markets. These are my main areas of interest that I have explored through the corses I have taken to complete my economics minor.

Projects and Work Experience

Teaching assistant for Distributed Embedded Systems (18-649) : Spring 2011

Real Time extensions for the Motorola Droid 2: Fall 2010
Using the resource kernel approach to real time operating systems, as a part of a team of four members, I created the framwork necessary for real time operation using high resolution timers. The semester long project was about building real time scheduling support and a real time monitoring system for the OMAP based Droid 2 phone.
I also implemented power saving algorithms using static frequency scaling. I implemented the system clock and Prioritiy Monotonic clock aglorithms.

Distributed Elevator control system: Spring 2010

Designed a highly distributed elevator as a part of a team of four members. We went about the engineering process of working out Use Cases, System Requirements, software statechart design, implementation and finally testing the system. The main object of the project was to ensure that all engineering processes were followed and a good quality and efficient elevator system was built.

The elevator was written and simulated in the JAVA programming language. The time triggered system was safety critical and hence we studied three basic techniques to ensure reliability FMEA,FMECA and Hazop analysis. The network was a real time network based on CAN and hence the network messages had to be scheduled and tested to ensure all deadlines were met.

As a part of the class we also studied different protocols such as: CAN 2.0, TDMA, CSMA/CA, CSMA/CD, Token Bus and FlexRay

Bell Switch dimmer and Capsense color picker Summer 2010

At Reiz electrocontrols I developed a dimming transformer to control the brightness of LED room lighting. As per the requirements, the transformer was to be compatible with three different types of dimmers and also allow the user to use a simple POT to dim the lights. As a part of a team of two, I designed the circuitry and write the software for the dimmer. A Programmable System on Chip , from Cypress Semiconductor, was used for this project. I designed and wrote the firmware and performed all bench testing on the product.

The Capsense color picker was a controller which was being developed for households as well as for hotels, enabling customers to choose the color of the lighting in the room according to their mood. Using a color gamut printed on a capacitive touch pad, interfaced with a microcontroller from Cypress Semiconductor, I developed firmware to mix colors and drive LEDs, also additional features such as multiColour and dimming were added to the touch pad.

Analog Circuits Spring 2010

As a part of the class assignmets and projects, I analysed and designed different amplifiers using BJT and MOS transistors. The circuits were designed based on a power and performance spec and then simulated on Cadence/Spice to test if all requirements were met.

Carnegie Mellon Solar Splash : Fall 2009 to Spring 2010

Carnegie Mellon Solar Splash is a campus organization involved in designing and building a solar powerd boat and participating in a world wide competition called Solar Splash. I headed the propulsion divion and was a part of the board. I was responsible for scheduling weekly meetings for the team where we would discuss designs and fabrication timelines. I researched how to calculate the propeller for our propulsion system and presented my findings. I also desined and built a support structure for the lower unit as well as an attachment for the tensioner. I co-authored a proposal and was awarded a Small Undergraduate Research Grant (SURG) for Propeller Development and Telemetry Systems for the boat.
