My research interests include: big data software engineering, software testing and analysis, and adaptive and embedded system. You are welcome to talk to me if you have common interests. Here is a list of my publications. You may also read my Google Scholar Citations or DBLP page (results always mixed with others).
Our research projects include CABOT and ADAM two series:
CABOT project (on issues outside software):
CABOT is a middleware infrastructure supporting context management for adaptive applications. It offers inconsistency detection and resolution services for validating application contexts. [BISON04, ESECFSE05, SCIS15]
ICC/PCC: ICC/PCC incrementally detects context inconsistency. It builds on partial constraint checking and is extremely efficient. It applies to general first-order logic based consistency constraints. [ICSE06, TOSEM10, TOSEM10a]
OCC: OCC optimizes constraint checking by removing redundant link generation in inconsistency detection. [SEAMS07]
DCC: DCC supports decentralized constraint checking and protects privacy of contexts. [PERCOM08]
CON-C: CON-C supports parallel constraint checking by multiple CPU cores. [SCIS13]
GAIN: GAIN supports parallel onstraint checking by multiple GPU cores. It is extremely stable. [APSEC14], IST16]
CINA: CINA suppresses the detection of unstable context inconsistency. It derives instability conditions from consistency constraints and makes smart inconsistency detection scheduling. [TSE15, TSE15a, correction for the formal version]
SHAP: SHAP suppresses the detection of inconsistency hazard (or unstable context inconsistency) by learning patterns (or instability conditions) from historical detection results. [APSEC14, IST16]
D-BAD: D-BAD resolves detected context inconsistency by heuristics. It identifies contexts being most likely faulty. [ICDCS08]
IMPACT/EFFECT: IMPACT/EFFECT resolves context inconsistency by minimizing side effect to applications. It is exhausitive but incremental, and thus efficient. [ESECFSE07, MOBIQUITOUS11]
CONSVIEW: CONSVIEW supports context inconsistency resolution among multiple applications. It uses consistent views to isolate applications from each other. [COMPSAC12]
AFCHECKER: AFCHECKER detects faults for model-based adaptive applications. It derives hidden features from adaptation rules and environmental data, and formulates deterministic and probabilistic constraints. Based on them, it prunes false positives in fault detection and prioritizes fault reports. [JSS13][website]
VERSA: VERSA verifies model-based adaptive applications under uncertain environments. It reports probabilistic verification results on faults. [ASE14]
SIT: SIT tests model-based adaptive applications under uncertain environments by adaptive sampling of sensory inputs. [JSS16]
RESYNC/REMATCHING: RESYNC/REMATCHING supports systematic recovery from consistency failure for model-based adaptive applications. It decides recoverability statically and supports it dynamically. [APSEC12, ASE13, MIDDLEWARE13]
UGA: UGA tests Android apps. It combines user input traces and random testing, systematically improving test coverage. [APSEC14, INTERNETWARE15]
COSEDROID: COSEDROID supports both computation and sensing offloading for Android apps. It can borrow computation resources and battery power from other devices. [COMPSAC15]
PERFCHECKER: PERFCHECKER diagnoses GUI lagging, energy leak and memory bloat issues for Android apps. [ICSE14][website]
ELITE: ELITE diagnoses wake lock misuses for Android apps. [FSE16]
CARE: CARE reduces synchronization and log overhead for recording and replaying concurrent Java programs. It supports value determinism. [ICSE14]
RWTRACE: RWTRACE combines wait-free notification in Stride and speculation-retry design in CARE for recording and replaying concurrent C programs. It is open-sourced. [ASE15][website]
BC: BC (Bisectional Coordination) uses spatial locality in shared memory accesses to significantly reduce access dependences in recording and replaying concurrent C programs. [FSE16]
AMCHECK/CACHECKER: AMCHECK/CACHECKER detects spreadsheet smells by program synthesis for formula patterns. [ICSE14][TSE16]
CUSTODES: CUSTODES detects spreadsheet smells by cell clustering with strong and weak features. [ICSE16][website]
TABLECHECK: TABLECHECK detects table clones and embedded smells in spreadsheets by fingerprint-based code clone detection. [FSE16]
ANOMALY: ANOMALY investigates how effectively spreadsheet anomalies can be detected by existing techniques. [JSS16]
C3: C3 automatically validates crash consistency for software by a generic oracle on checking editing distance and systematic test amplification for execising interleaved behavior. It is open-sourced. [FSE16]

Hobbies and Thoughts
I love playing computer games, watching movies, hiking, thinking and daydreaming (O_O).
I am interested in game development. In early years, I worked with friends on two RPG games: NewPal and FreeRPG. We focused on a reusable game engine and supporting tools, and developed demo stories on them. Developing a complete game is different from just develping a demo. You may want to take a look at SDLPAL as a good example of complete game. Game development also requires passion. One positive example is Notch (刻痕) game series. Its first version was made by a non-cs student, who was also the main developer of later versions. All their pictures, music and stories are new, and all team members are students. SDLPAL and Notch are free games. You can find them from the Internet.
You may have experienced worries. Sometimes we care about how others think of us. Although we can learn from others' stories, we have to make our own decisions. Usually, following the way you have choosed by yourself, you will not feel regretful. When you feel worries, you may want to take a look at these words.
