Research assistant: An Integrated and Automated Electronic System for Point-of-care Protein Testing (Sponsored by Analog Devices, Inc., Maxim Integrated and Novartis Institutes of Biomedical Research) (Sep. 2012 to Dec. 2019) • Worked on the project independently and reported to industrial collaborators • Developed a bead-based electrochemical immunoassay on an integrated microfluidics and built an end-to-end mathematical model to inform optimization • Developed an electronic system which features microfluidic control and multiplexed amperometry. The amperometric circuit simultaneously measures up to 16 samples with less than 200pA of noise. The control circuit automates the multi-step bead-based assay on microfluidics • Demonstrated automated measurement of protein biomarkers in patient samples with clinically relevant limit of detection and within 25 minutes • First Place Winner of the 41st International Engineering in Medicine and Biology Conference Student Paper Competition Soccer Data Collection and Analysis System • $5000 award by MIT Innovation Fund Program • Built probabilistic model to fuse Wi-Fi and Bluetooth signals with GPS data from smartphones; implemented particle filtering algorithm with python script; preliminary experimental results showed improvement of 20% when simultaneously tracking 4 smartphones • Demonstrated a UWB-based localization system which allows accurately tracking player positions • Developed algorithms for event detection and statistics analysis from the raw sensor data Teaching Assistant: 2.674/2.675 Micro/Nano Engineering Laboratory (Sept. 2014 to Jan. 2015) • Prepared materials and tested lab setups for a class of 40 students, assisted the professor and the instructor with lab instruction; helped students with their projects including participating in projection discussion and device fabrication; graded the exams

Research assistant: Photoacoustic Imaging of Biomedical Tissues (Institute of Acoustics ) (Sep. 2009 to Jun. 2012) • Developed an automated photoacoustic imaging system, where a pulsed lase, an ultrasonic transducer, an NI data acquisition card and a custom-built servo motor were controlled and synchronized in LabVIEW to generate and collect acoustic signals• Developed algorithms to reconstruct images from the raw acoustic signals • Applied acoustic theory to reduce artifacts and improve imaging quality, published results in leading journals of the field Research assistant: Noninvasively Monitoring of Vocal Fold Vertical Vibration Using Acoustic Doppler Effect (Sep. 2009 to Jun. 2010) • Developed algorithm to derive vocal fold vibration speed from measured Doppler frequency Teaching Assistant: Acoustic measurement Laboratory (Sept. 2010 to Jan. 2010) • Independently instructed lab sections for a class of 20 students; graded lab reports
