Junyi Zhu (朱均逸)

Assistant Professor

Electrical Engineering & Computer Science Department

University of Michigan - Ann Arbor

I am an Assistant Professor at University of Michigan, Electrical Engineering and Computer Science (EECS) Department, leading the Sensing, Intelligence and eXperience (SIX) Lab.

We work at the intersection of Human Computer Interaction, fabrication and novel sensing technologies. I completed my Ph.D. degree in Computer Science at MIT EECS Department & CSAIL, advised by Prof. Stefanie Mueller at the HCIE Group. I design and fabricate personalized health and medical sensing devices that

can be used for both dynamic in-field environment for remote monitoring and diagnosis session, as well as in-clinic monitoring along with other medical procedures, to provide more temporal and spatial information for doctors and physicians. I am a 2017 Seneff-Zue Fellow, a 2021 Thomas G. Stockham, Jr (1955) and Bernard (Ben) Gold Fellow and a 2023 Seibel Scholar.

Prior to MIT, I completed my Bachelor's Degree at University of Washington in Electrical & Computer Engineering Department, concentrated in Embedded Computing Systems, worked as a Research Assistant at UW Ubicomp Lab, a part-time Software Engineer at Senosis Health, and a Teaching Assistant at UW Electrical & Computer Engineering Department.

I am recruiting undergraduate and graduate researchers (PhD & Postdoc). If you're interested, feel free to check out our lab website and shoot me an email!

Research Vision

I envision that in the future, every individual will have a personalized health monitoring system that adapts to individual variance, for both macro & micro circulation

systems, which consists of health monitoring device(s) with custom sensing functions based on the patient’s health conditions, with unique device form factors based on the patient's body shape and usage context, as well as patient specific models for analyzing the collected data, just how doctors customize treatment and recovery plans for every patient in-clinic. With my background in health sensing, fabrication and human-computer interaction, I am uniquely positioned to design and fabricate personal health and medical devices, build signal processing models for individual patients and their specific conditions, and deploy my devices in studies with doctors and patients.

Other Fun Projects

Mixing Frames: A Video-oriented Approach to Video Super-resolution In this work, we propose a video-oriented approach to video super-resolution: instead of building an all-in-one neural network for all types of videos, we instead train several different networks with various performance features, and based on the video clip’s characteristics (i.e. color saturation, movement frequency in terms of frame blurriness), pick the most suitable model(s) for each part, even mixing them up if necessary.	Parking System for Capitol Hill A district shared parking system for Capitol Hill Housing by using RFID tags and WISPCam (a battery-free RFID camera). The RFID tags monitor the cars going in and out to get the number of cars inside the garage and how many free spots are left. The WISPCam inside the garage will show which specific spots are available, which is achieved by machine learning. All the information are displayed on our own website and self-built mobile application. The project has been filed for a patent.	BiliCam iOS development for an existing research project, BiliCam, a smartphone-based non-invasive medical application that uses the on-device camera to monitor jaundice in newborns, and improve its scalability and the user interface along with assessment processes to match user habits. Redesign the machine learning models so that is matches the FDA approval standard.
Drone Hacking & Overcontrol Use Wireshark to hijack the proprietary communication protocol of a Parrot mini-drone through a self-developed Android Application, and featuring cross-communication between it and Arduino board through both Bluetooth and Wi-Fi, controlled by human motion.	Pokémon Game via FPGA Adopted from the famous Japanese GBA game. The game is designed for two players to play on two separate FPGA boards, each embedded with self-built microprocessor and asynchronous serial network system.	Air Pollution Monitoring Assist with community air monitors for Imperial, CA. The crew in SEAL Lab & Seto Lab already deployed 20 monitors last year, and the next 20 new monitors will be designed for this year. Data are streamed to UW servers via Wi-Fi connections by Arduino board in monitors. Data can be viewed through a self-designed mobile application.
