WORK

EXPERIENCE: Spectral MD, Inc. Dallas, Texas, Jan 2013 - Present Software Engineer, Engineer Group

• Design the GUI, OpenCV (C computer version, object tracking

• Signal Processing : Blinded Signal Separation --- PCA, ICA, CCA, etc

• Machine Leaning: Scikit - learn (Python) --- K-NN, Neural Network, SVM, etc.

RESEARCH

EXPERENCE: • Change My Voice Based on Android Platform, App development, SMU, Fall, 2012

By using the knowledge of digital speech processing and using Sound library(Java API) to change

harmonic, pitch of audio on the Android Platform, and receive and send data, which is based on

Session Initiation Protocol (SIP) in real time.

• Vector Quantization and Turbo -- Code in Communication System, Error Control Coding, Fall, 2012

Source signal (Image) can be Analog/Digital convert by using Vector quantization(K-NN), then implete

Channel Coder by using Turbo-Code, through Additive White Gaussian Noise channel, using SOVA or

Log-MAP decoder, and Vector Quantization to reconstruct image.

• Speech Recognition by DTW, Project of Digital Speech Processing, SMU, Fall, 2012

Creating the Dynamic Time Warping(DTW) algorithm routine (Matlab), finding the shortest

distortion in speech model, understanding the Viterbi Algorithm, Hidden Markov model, etc.

• Data Analysis of CHB-MIT Database, Project of Medical Signal Analysis, Spring, 2012

By using wavelet transform to find the features of EEG signal, creating Autoregressive Mode and

Moving Average Model, get parameters to detect seizure and non-sizure signal.

• Communication System -4QAM, Project of Digital & Analog Communication, SMU, Spring, 2012

Have a simulation of Communication System, 4-QAM, Conceptions related to matched filter, white

noise, fading channel. Having an analysis in how to reduce Inter-symbol Interference (ISI) and get low

Bit Error Rate (BER).

• An Enlargement method of Digital Images, Project of Digital Signal Processing, Fall, 2011

Implemented higher-resolution image through Laplacian pyramid algorithm.

• Research Intern, Biological Information Processing Lab, Lanzhou University, Feb 2011- June 2011

By using the knowledge of Chaotic System and Discrete Fractional Fourier Transform describable,

detect biological signal (EEG). Focusing on Chaotic theory related coder in the communication system.

Programming Skill: Matlab, C/C++, Python, Java
