Biography

I am a tenure-track Assistant Professor at Southern University of Science and Technology. On March 2018, I obtained my PhD degree from School Of Computing in National University of Singapore. During my PhD studies, I was advised by Prof. Abhik Roychoudhury. Previously, I received my bachelor and master degrees from Department of Computer Science of University of Illinois at Urbana-Champaign. During my Master studies, I was co-advised by Darko Marinov and Lin Tan.

My CV is available for download here.

My research interests include:

Automated Program Repair
Software Testing
Comment Analysis
Software Evolution
Test Repair

Research Projects

Droix	Visit Website
Droix is a novel automated repair framework for Android apps. Droix could repair crashes based on one crashing UI input. We also propose Droixbench, a benchmark that contains a set of reproducible crashes in Android apps.
Codeflaws	Visit Website
Codeflaws is a benchmark that allows objective evaluation of program repair tools across defect classes.

Anti-patterns in Search-Based Program Repairs	Visit Website
Instead of using repair patterns obtained from human patches, our set of anti-patterns can be enforced on top of any search-based program repair tools. Enforcing anti-patterns in repair tools produces repairs faster, localizes better, and deletes less.

relifix
A test-driven automated repair tool that uses a novel set of contextual operators for automated repair of software regressions. Our set of operators uses syntactical information from changed statements. Repair more bugs than existing program repair tool, GenProg and our generated repairs are less less likely to introduce new regressions than GenProg.

Software Change Contract	Visit Website
A language that could be used to specify intended effect of program changes. Change contract focuses only on the program changes and their intended semantic effect. Program behavior that is unchanged across version does not need to be captured.

@tComment	Visit Website
Novel approach that automatically generates unit tests that check for inconsistencies between Javadoc comments written in natural languages and Java source code. Reported 24 inconsistencies in 6 open-sources Java projects.

ReAssert	Visit Website
A tool that automatically repair broken tests with the push of a button.

Software Patents

Software program repair	Patent
Hiroaki Yoshida, Shin Hwei Tan, Mukul R. Prasad
(Abstract) According to an aspect of an embodiment, one or more systems or methods may be configured to locate a fault in a software program using a test suite. The systems or methods may be further configured to modify, using a repair template, the software program in response to locating the fault. In addition, the systems or methods may be configured to determine whether the modification satisfies an anti-pattern condition. The anti-pattern condition may indicate whether the modification is improper. The systems or methods may also be configured to disallow the modification in response to the modification satisfying the anti-pattern condition or perform further testing on the software program, as modified, in response to the modification not satisfying the anti-pattern condition.
