Objective

Seeking an entry-level industry position where I can apply my hardware design experience and my programming skills to de- velop impactful technology. I am most interested in being in an engineering environment that will challenge me, allow to me continue to learn, and provide strong career opportuni- ties.

Work Experience

Asst. Researcher, Sonic Arts (present)

Research and develop microphone/loudspeaker array

beam-forming algorithms.

Intern,Center for Astrophysics and Space Sciences

-Summer 2013

Participated in an undergraduate radio astronomy

project. Surveyed astronomical objects via radio tele- scope system. Fabricated antenna feed for dish receiver, as well as a system noise calibration device. Provided data analysis results and gave presentations on the project. Projects

Digital Adder Design

Designed a power efficient, high speed, low-area 8- bit adder. Designed a 14-T, 1-bit adder at the tran- sistor level. All transistors were sized for equal pull up/down strength. Designed a carry-skip adder with eight, 1-bit blocks, and propagate/generate blocks. A physical layout was designed and tested in Virtuoso. Speech Compression

Quantization of an audio signal caused distortions which were minimized by fitting the signal to an auto- regressive model and solving for the noise. The noise was quantized and transmitted. Signal reconstruc-

tion achieved by knowing the quantization rate and computing filter coefficients via a minimum norm

least-squares approach.

Global Positioning System

Produced a generalized non-linear least squares gra- dient descent algorithm. Using time-stampped pseu- dorange information from four satellites the location of a geostationary reciever was predicted with little error. Performance of various generalized gradient de- scent algorithms were compared.

Sign Language Telemetry

Team design hardware, & software to translate sign language to text on a computer. A piezo-resistive

sensor array, arranged on a glove, serves data to a mi- crocontroller. Data is fit to a d-dimensional Guas- sian pdf and then a maximium likelihood estimation is made via the natural logarithm of Baye’s decision

rule.

IIR&FIRNotch Filter Design

Processed audio signal via OMAP-L138 C600

DSP+ARM module. In Code Composer, an echo

effect & sine tone were added to an audio signal. By manipulating an ideal lowpass filter, a FIR notch fil- ter was designed and implemented. A pole-zero plot was also constructed and manipulated to achieve an IIR notch filter. Each design was used to filter out the sine tone.
