In May 2018, I graduated with the Sc.B in Electrical Engineering from Brown University. In September 2018, I began the M.S./Ph.D. program in Electrical Engineering at Columbia University. I work with Professor Gil Zussman at the Wireless and Mobile Networking Lab.

My research interests include the design of networking algorithms at the PHY and MAC level, full-duplex networking, mmWave devices, and how these separate concepts will together form the basis of beyond-5G networks. I am currently working on several projects, including the deployment of an open-access full-duplex wireless testbed in the COSMOS testbed, and investigations into the wireless channel at sub-6 GHz and 28 GHz mmWave. For more details, please see my CV.

While I was in my senior year at Brown, I had the opportunity to lead the electronics development for a nanosatellite named EQUiSat. For more information on this unique project, please see the blurb at the bottom of this page.

Industry and Project Experience

  • Research Intern, Nokia Bell Labs
    June 2019 – August 2019

    • Worked with the Access Lab on 28GHz wireless. Mentored by Jinfeng Du and Dmitry Chizhik.
  • Applications Engineer Intern, ON Semiconductor
    June 2017 – May 2018

    • I designed demonstration/evaluation circuit boards for future product releases. The boards were designed to allow customers to evaluate the product with simple lab equipment. To do this, each of the two boards I developed incorporated an Arduino and LCD screen which provides diagnostic information to the user that can be referenced with simple to read on-board silkscreen data tables. I was responsible for the board design, Arduino software, debugging, and technical documentation.
  • Avionics Hardware Lead, Brown Space Engineering
    May 2017 – May 2018

    • When I was at Brown, I was the avionics hardware lead in the last year of development of a 1U CubeSat known as EQUiSat. This project was funded by NASA under the Educational Launch of Nanosatellites (ELaNa) Mission 23 and we built EQUiSat with a two-fold goal in mind. First, we would show that space is reachable even by a team of undergraduate students, and second, we would test the viability of lithium iron phosphate (LiFePO4) battery chemistry in a space application. We designed EQUiSat entirely from scratch, aside from the radio unit, and built her with a parts budget of under $5,000 over a five-year period. EQUiSat was launched to the International Space Station on May 21st, 2018 and deployed into low-earth orbit on July 13th, 2018, where she would work flawlessly until until December 26th, 2020, when her last transmission was received as she re-entered the Earth’s atmosphere. As the testament to our completed goals, EQUiSat exceeded her expected mission duration by over 20 months.

      EQUiSat’s hardware design is open source and may be found here. In particular, I developed the final version of the battery charging board, and the first iteration of the ground station used to listen to the satellite. I built and tested a significant portion of the electronics and some of the mechanical systems by hand.
