I'm a student at University of Michigan Ann Arbor planning on graduating in 2018 with a degree in Computer Engineering and a minor in Mathematics. During the school year I work in the Embedded Systems Lab (Lab 11) at the University of Michigan, under the supervision of Prabal Dutta.

This past summer (2016) I worked at the Uber Advanced Technologies Center in Pittsburgh, PA. For more information about Uber ATC, see this article.




Academic Papers

...

Pedestrian Detection Using Lidar

Final paper written for EECS442 class. Used correlated Lidar and image dataset to identify pedestrians through segmentation, feature extraction, classification, and filtering. (Fall 2016) [paper] [lidar-img-objectDetection repo]




Projects

...

Speaker Diarization using MFCCs

This is the final project website for EECS351. Performed speaker diarization using Mel Frequency Cepstrum Coefficients (MFCCs) and Mahalanobis distance. Also explored envelope features and kth nearest neighbor algorithms. (Fall 2016) [website] [eecs351project repo]

Signpost LoRa Communications

The signpost project was a Lab11 project with the goal of putting modular computers (sensors could be simply plugged in) on signposts, with the goal of enabling city scale sensing. For this project I chose the LoRa module to use, how to configure LoRa parameters, and wrote a Node.JS library (iM880-serial-comm) to interface with the module. (2016) [LoRa-comms repo] [iM880-serial-comm repo]

...

SensEye-2

This is the GitHub repository for the SensEye-2 project, I worked on as a part of Lab11. The goal was real-time gaze detection of a human eye using a pair of glasses with low-power cameras mounted facing inward and outward. This information let the system determine where the eye was looking and whether the gaze was shifting. (2015-2016) [SensEye-2 repo]

...

Meta-Drone

This is the website for the Meta Drone, an integration of the Parrot Drone and the Meta Glasses my team made at MHacks V. It was the winner of best Virtual Reality Hack. (2015) [website]

A Novel Beamforming Approach to Stereo Sound

Designed a new beamforming approach for near-field applications (less than one meter) to create true stereo sound. Signals were time-delayed in order to converge on each ear of the user and create lobes of sound, instead of creating a traditional beamforming wave-front. See the paper I submitted to the Intel Science Talent Search and Siemens Competition in fall 2013, a webpage I created in 2014 for my TJHSST Senior Project and the GitHub repository with the project source code. (2012-2014) [PDF] [website] [beamformer repo]

Design of a FPGA Interface for an Analog to Digital Converter

I wrote this paper on the work I conducted over Summer 2013 at NASA Goddard Space Flight Center. It focuses on creating an interface between an external Analog to Digtal to Converter and a Field Programmable Gate Array (FPGA). (2013) [PDF]

Aerospace Club

As part of Excelsior Aerospace Club we both work on Project SOAR and on the Battle of the Rockets competition. Project SOAR planned to use a balloon to take a fixed-wing UAV to 100,000 feet then fly it down collecting data. Battle of the Rockets was a yearly competition to launch a rocket containing a rover to 1000 feet then deploy to rover and complete tasks on the ground. (2010-2014) [website] [bor-rover repo]
