• Implemented codecs for OpenBMIP and OpenAMIP protocols in C and a utility that transmits OpenBMIP via UDP and OpenAMIP via TCP to support hardware testing• Created a tool in C that configures and manages a Ballard UA2000 avionics device used to spoof ARINC 429 messages to flight hardware • Incorporated the OpenBMIP, OpenAMIP and ARINC 429 tools into a web app using ExpressCPP, Lighttpd, and Angular which has been deployed in 10 testbeds including 2 instances in the Delta Airlines lab• Made wiring diagrams for test hardware and collaborated with multiple teams in order to conduct integration testing as well as debug system wide issues• Developed mobile-VSAT features that communicates with a GEO satellite to enable flexible reference signal generation, monitor GPIO, and enhance installation GUI • Wrote scripts in Python to create input files for the web app as well as process field data collected from mobile-VSATs deployed on commercial flights

College Park, Maryland, United States

•Created a sensing unit that utilized LiDAR and an ultrasonic sensor mounted on a servo motor to detect glass in indoor environments•Developed a sensor processing module in Python that was used in conjunction with a SLAM algorithm to create a map of the environment with 80-85% accuracy of detecting glass features•Utilized ROS to process raw sensor data into an input format for the SLAM algorithm and to produce meaningful visualizations and data captures

•Creating a context-aware system to create a stress detection application using Python, MPI and the Akka Actor framework•Employed Kafka for message passing between services within a microservices architecture

College Park

•Creating a custom effort controller using C++ and packages from ros_control for the UR-10 Arm and Shadow Hand to utilize tactile feedback from a BioTac sensor•Performed 3D simulations using Gazebo and RViz within a Docker container to verify correct finger manipulation•Implemented ROS packages that enable the Shadow Hand to grasp an object and play the piano

College Park, Md

•Teaching undergraduate students’ concepts about elementary algorithms related to sorting, graphs and trees, and combinatorics•Evaluating student performance by creating rubrics collaboratively with other teaching assistants to grade exams and homework

• Represent the College of Computer, Mathematics and Natural Sciences (CMNS) to incoming/prospective freshman

College Park, Maryland, United States

•Led a team of 6 that designed, implemented, and tested software to operate a tunnel boring machine (TBM) •Implemented bare-metal software in C/C++ to interface with sensors and actuatorsusing a distributed system of STM32F767 microcontrollers •Developed a global state machine for TBM operations coordinating hydraulic valve actuation, high-voltage motor control, and E-STOP procedures•Utilized a CAN bus between microcontrollers for keepalive messages, control messages, and sensor data acquired via UART, ADCs, and SPI•Applied the CANopen protocol to communicate with a high voltage motor controller

College Park

•Created a new dataset applicable to train models to categorize the engagement of a patient by consolidating information from practicing psychiatrists

College Park, Md
