About Me

I am currently a phd student at ECE Department, Northeastern University. My advisor is Dr. David Kaeli. I am a member of Northeastern University Computer Architecture Research Group (NUCAR). I received my B.Eng. degree of Computer Science from Beijing University of Posts and Telecommunications (BUPT) in 2010.


My research interests are parallel computing on different platforms, including GPU (Graphic Processing Unit) and distributed systems. I have worked on various GPU-accelerated algorithms in the domains of speech recognition, medical ultrasound imaging and recommender system.
I am working on several projects where machine learning techniques are used in various domains, such as understanding environmental contamination factors linked to pre-term birth and reducing carbon-nanotube experiment design space.
Recently I started to work on accelerating general machine learning tasks using GPUs, Hadoop and Spark. I am currently working on the integration of GPUs in Spark to utilize the power of GPU and the scalability of Spark for large-scale machine learning tasks.


Medical Ultrasound Imaging on GPUs

I have transferred Synthetic Aperture Sequential Beamforming in ultrasound image processing onto GPU when I was in Technical University of Denmark as a trainee researcher.
I have also worked with BK Medical on processing ultrasound images on GPU.

Data Analysis on Spectral Biological Sample Data

I have used various machine learning models such as clustering, dimension reduction and regression to analyze biological sample data from Puerto Rico with the goal of establishing linkages between environmental pollutants and preterm birth.

Data Mining on Carbon-nanotube Fusion Process Design (ongoing)

I am using data mining techniques to reduce Carbon-nanotube design space to accelerate the Carbon-nanotube fusion process.

Sports Prediction using Gaussian Processes (ongoing)

I am mentoring four undergraduate students to develop a framework that uses Gaussian process to predict the margin of victory for NFL games.

NICE (Northeastern University Clustering Eigine) Project (ongoing)

I am the mentor of 9 undergraduate students mostly funded by REU program. Our group is developing a framework that supports interactive big data visulization in web interfaces to help reserchers from bioinformatics and environmental engineering domains better understand and explore their data.

Work Experience

I have worked in AMD as an intern on a project that executes the compute-intensive part of Mahout on APUs in heterogeneous clusters.
