Software development engineer
I’m a software development engineer at Apple in love with math, movie and badminton.
My favourite theorem is Gauss-Bonnet Theorem.
$$\iint_M K\,dA\ = 2 \pi \chi (M)$$
Location system/algorithm design and project lead for iPhone and iPad.
Supported SOC Location Software development and update for more than 500M mobile devices, including flagships Galaxy S22, Galaxy Watch 5 and 6.
Implemented a flexible extended Kalman filter (EKF) algorithm to process inertial and GPS measurements recorded in ROS and estimated the vehicle’s position and velocity, assessed the performance, and developed integrity bounds to robustly and accurately infer autonomous vehicle’s location.
Obtained Ph.D. in Mechanical Engineering at Tufts University. I also hold degrees in Computer Science and Geomatics Engineering. My research focuses on Guidance, Navigation, Control, Robotics, and Automated Systems.
Participated in the Graduate Institute for Teaching (GIFT) program. Attended a series of summer workshops on teaching pedagogy, and will co-teach a graduate-level class "GPS & Satellite Navigation" with Prof. Pratap Misra in 2019 fall.
Constructed a GPU based real-time GNSS software receiver with graphical user interface (GUI), which later became the testbed of the neighboring BeiDou System (BDS) RF frontend group, and a habitat for new GNSS-related algorithms developed by graduate students.
