About Me

I'm a PhD student in computer engineering at Iowa State University, working with super cool prof. Srikanta Tirthapura. I received the B.Eng. in software engineering from Hanoi University of Science and Technology in 2014, along with the Graduation with Honors Awards.

I started research when I was undergraduate student and found myself deeply interested in. I was a research assistant in couple projects and have proud achievements in Wissim project, where I anticipated in both theory study and software engineering development.

Pursuing PhD degree in computer engineering, I challenged myself in field of Data Mining, Data Stream Mining, Machine Learning, and Feature Selection to take advantage of large-volume data available in computer engineering nature, source codes, system logs, streaming data… to solve research problems, code migration, anomaly detection, insider attack detection… My last publication has been accepted at ICSE-2017, #1 conference in Software Systems.

Data Sampling and Approximate Query Processing

Data Sampling

Approximate Query Processing using Sample Table to Reduce Resources Consumption

We are building a database system, that uses sampling to reduces resources consumption while it can give approximated aggregates. Sample procedure includes drawing samples, tunneling queries over sample tables and properly scaling up the aggregates. We develop unbiased and biased methods, including stratified sampling, to optimize the given budget space to have the most representative sample. We are especially considering cases of group-by query, with combination of multiple aggregations over multiple group-bys.
Along with different computational methods, we also develop software toolkit and an interactive system for massive streaming data warehouse. The system supports streaming sampling algorithms and data sketching for large-scale data analysis. Which can provide approximate results, with a controlled-error bound, in orders-of magnitude faster than querying over original data.

Wissim

Wireless Sensor Network Routing Algorihtm and Simulation

I was the key menber of Wissim project when I was undergraduate. This project of my formal lab aims to develop energy-efficient routing algorithms for wireless sensor networks, especially networkds deployed in an abnormal surface with potentially large holes. We also develop the friendly simulation tool, which allows user to deploy their own routing algorithms, create simulation scripts with various configurations and do experiments on their own algorithms as well as the build-in well-known algorithms.
