Biography
|
|
I obtained my Bachelor's
degree from the
Department of Computer Science and Technology
,
Nanjing University
in June 2003. I obtained my PhD degree at
the Department of Computer Science and Engineering,
Hong Kong University of Science and Technology
[HKUST],
under the supervision of
Dr. Lei Chen
, in August, 2009. After that, I worked as a post-doctoral fellow at the Department of Computer Science and Engineering,
Hong Kong University of Science and Technology
[HKUST].
In 2010-2011, I was also a research assistant professor at the HKUST Fok Ying Tung Graduate School.
In 2011-2016, I worked as an assistant professor at the Department of Computer Science,
University of Texas Rio Grande Valley [UTRGV, Edinburg Campus]
(former name: University of Texas - Pan American [UTPA]).
In 2016-2021, I worked as an assistant professor at the
Department of Computer Science, Kent State University [KSU].
Starting from September 2021, I am an associate professor at the
Department of Computer Science, Kent State University [KSU].
I am directing the Big Data Science Lab [MSB 253, phone: (+1) 330-672-9123], Department of Computer Science, Kent State University.

Research Interests
|
|
My main research interest is in databases. In particular, I am interested in query processing over:
-
Probabilistic, Inconsistent, and Uncertain Databases
-
In real applications such as location-based services (LBS), RFID/sensor networks, data extraction/integration, and medical data analysis,
the underlying data are inherently imprecise and uncertain, due to various reasons such as imperfect nature of sensing devices,
inaccuracy of information extraction methods, unreliability of data sources, and/or privacy preserving. Therefore, these application data can be
modeled by probabilistic and uncertain data. Compared with certain data, uncertain data are those tuples/objects associated with probabilistic confidences that are either independent or
with arbitrary correlations. Moreover, in some applications such as data extraction/integration,
the extracted/integrated (probabilistic) data may violate some integrity constraints (e.g., functional dependencies) and thus be inconsistent.
Due to the data uncertainty and inconsistency, it is challenging to efficiently and accurately organize and
answer various probabilistic queries over such probabilistic/inconsistent/uncertain data.
-
Uncertain and Certain Graph Databases
-
Uncertain and certain graph databases have been widely used in many real applications such as the Semantic Web (e.g., workflows and XML/RDF graphs), social networks,
scientific databases (e.g., chemical compound databases, biological graphs like protein-to-protein interaction networks and gene regulatory networks, etc.), and transportation systems (e.g., road networks).
There are many interesting research topics on efficient query answering in uncertain/certain graph databases, such as keyword search queries over (probabilistic) RDF graphs,
route planning over road networks with uncertain traffic conditions, and variants of subgraph matching over (probabilistic) RDF graphs, biological graphs, or social networks.
While the manipulation over complex graph structures itself is quite costly, the query processing over probabilistic graphs is more challenging (since more constraints
such as labels (keywords), probabilities, and correlations are involved).
-
Streaming Time Series
-
The streaming time series have many real applications such as financial stock data analysis, sensory data analysis, trajectory data analysis,
multimedia (audio or video) databases, and so on. In this direction, it is interesting to study the efficient and accurate detection/prediction of critical events
(corresponding to some query patterns), such as the falling/rising of stocks, fire events, or behaviors of mobile users' trajectories, over streaming time-series.
-
Spatio-Temporal Databases
-
The spatio-temporal databases have real-world applications such as geographical information systems (GIS), multimedia databases, and location-based services (LBS).
It is quite important and useful to study various spatial queries (such as range queries, k-nearest neighbor queries, and reverse k-nearest neighbor queries over static/moving spatial objects)
in different scenarios such as high-dimensional spaces, subspaces, metric spaces, and data streams. In order to tackle these problems,
it is challenging to design effective pruning methods specific for spatial query types to reduce the query search space, and propose the optimized indexing and query processing
approaches to efficiently retrieve spatial query answers.
-
Spatial Crowdsourcing
-
A spatial crowdsourcing platform provides an opportunity for users (task requesters) to utilize the power of humans
to acomplish some complex or time-consuming spatial tasks (e.g., checking whether a supermarket has a specific product,
or whether or not a restaurant far away from a user is open). Existing spatial crowdsourcing systems include Waze, Gigwalk, TaskRabbit, gMission, and so on.
Given a number of workers and a number of spatial tasks, a typical spatial crowdsourcing problem is to assign
moving workers to do spatial tasks so that some constraints (e.g., task deadlines, maximum budget, task quality, etc.) are satisfied
or some criteria are optimized (e.g., the total budget is minimized, or the number of completed tasks is maximized). The task assignments in the
spatial crowdsourcing problem can be considered as an optimization problem, which is usually NP-hard and intractable.
Therefore, it is challenging to design approximation, near-optimal algorithms to efficiently assign workers with spatial tasks
with good quality.
-
Incomplete Data Management
-
In many real applications like sensor data monitoring, intrusion detection in IP networks, social networks,
Web data analysis, and so on, the collected/extracted data often contain missing attributes, due to various reasons such
as network traffic congestions, hardware/network failures, incomplete profiles not entered by users, or
the inaccuracy of the data extraction. While existing data analysis tools often assume that the underlying data
are complete, they usually cannot effectively and accurately handle incomplete data. Therefore, incomplete data
management is rather important and useful in practice. Interesting research problems include the design of
accurate data imputation techniques, and efficient data processing algorithms to perform online data imputation
and query processing at the same time.
