Current Project: CAVE
Immersive Cabin (IC) is a 5-wall CAVE(CAVE Automatic Virtual Environment) in Stony Brook University, which consist of 5 back projected walls and a front projected floor. This facility delivers a 360 horizontal field of view and saturates most of vertical view of user. The IC uses two projectors per wall to deliver stereoscopic images that are viewed using active shutter glasses. By combining motion parallax from head tracking with depth perception from stereoscopic display, this facility can help users to explore complicated virtual environments and easily distinguish between objects in a complex scene. The immersive stereoscopic experience of IC makes it suitable for various applications such as medical visualization, virtual architecture tours and urban planning. Visualizing the E-coli bacteria and virtual colonoscopy are good examples of how the IC can be used in the context of medical and scientific visualization. During the last years a numbers of buildings (Simon Center, RSS) have been constructed around the campus. Prior to each construction, building architects virtually explored the CAD drawings in 1-to-1 scale and iterated on their designs. Last but not least a futuristic visualization of Manhattan urban area is also available to demo on IC.

Our group is interested in studying, understanding, and modeling large-scale data. We focus on problems involving massive graphs (GATA); including link analysis, pattern discovery, and outlier/anomaly/fraud/event/outbreak detection. Our goal is to develop algorithms and scalable analytics for mining & learning from (graph) data.
Current Project: An Ensemble Approach for Event Detection and Characterization in Dynamic Networks.
Event detection in temporal graphs, such as cyber and communication network traffic data, has many key applications in systems monitoring and security. It also has useful applications in detecting real life events from news corpus, email communications, cell phone communications and so on. Dynamically monitoring the network over time to detect suspicious changes in its structure and behavior is a challenging task due to the evolving nature of the data. In this work, we develop an ensemble approach for real-time event detection and characterization for dynamic graphs. We propose to use five detection techniques that can rank the time points by their anomalousness, the results of which we combine to come up with a final ranking. What is more, we characterize the events; by identifying the main network entities, i.e. specific nodes and edges, that are responsible for the detected changes the most. Our ensemble also employs a rank merging strategy to rank these entities by the magnitude of their suspiciousness. There are two key features of our approach: (1) it is designed to operate in a real-time fashion, where the decisions are made as new data arrives, and (2) the ensemble approach yields a better ranking, thanks to its voting mechanism. We use both simulated data (network flow) and real data (New York Times news corpus and email communication of Enron Inc.) for our experiments. At first experiments are performed on cyber network flow data, carefully simulated at a large corporation with ground truth events. Our proposed method has successfully identified the time points in which the network went through suspicious state changes, as well as the key network agents that instantiated these changes which are verified quantitatively. Experiments on New York Times news corpus in the setting of temporal graphs with co-occurrence of named entities in the same article and also on email communication network of Enron Inc. successfully identified some important real life events and the entities associated with those events.

Current Project: How Fast is NFSv4.1 -- A Benchmark Study of the Linux NFSv4.1
We present a benchmarking study of Linux’s implementation of NFSv4.1, the latest version of the NFS protocol. The NFSv4.1 servers in the 2.6.32 and 3.12.0 kernels performed well in most of our experiments. However, we also observed that Linux’s memory management can waste up to 80% of NFS I/O throughput. NFS performance also suffers from unfair networking behavior that causes the throughputs of identical NFS clients to differ by a factor up to 19×. We show that NFS delegations can boost performance by saving up to 90% of network traffic, but a delegation conflict can cause a delay of at least 100ms—more than 500× the RTT of our 1GbE network. We also found that NFS can exhibit counterintuitive performance behavior due to its intricate interactions with networking and with journaling in local file systems.

Current Project: Comparing the RNA-seq and Microarray Platforms with Generalized Linear EIV Model
The discovery of gene biomarkers and related pathways is critical in the studies of disease and therapeutic treatment. The rapid evolution of modern biotechnology has generated several waves of measurement platforms – with some phasing out, while others co-sharing the market. Two front runners are the more traditional gene microarray technology and the newly arrived RNA-Sequencing (RNA-Seq) platform. An intensive literature review revealed that the prevalent statistical method for the comparison of the Microarray and the RNA-Seq platforms is the Pearson product moment correlation coefficient. However, the Pearson correlation is unable to provide a calibration formula to convert the expression levels between the platforms. It also fails to account for the fixed and proportional biases between the two platforms. To fill this void, we have developed a method based on the generalized linear errors-in-variable (EIV) model that is able to provide both a calibration equation as well as a statistical measure of the two biases.

Current Project: Scalable Parallel Processing Algorithms for Sequence Alignment and Assembly
High-throughput next generation sequencing (NGS) technology has quickly emerged as a powerful tool in many aspects of biomedical research. However, along with its rapid development, the data magnitude and analysis complexity for NGS far exceed the capacity and capability of traditional small-scale computing facilities, such as multithreading algorithms on standalone workstations. To address these issues, we try to develop solutions using the ever-increasing supply of processing power by massive parallel processing (MPP) systems. We have designed a scalable hierarchical multitasking algorithm for importing classical sequencing algorithms to modern parallel computers. More specifically, we have developed a novel parallel infrastructure, which includes a portable NGS-oriented messaging package that adapts well to heterogeneous communication systems, and a scheduling package that provides a dynamic balancing strategy for efficient task scheduling. Based on these, a unified software suite, entitled “PPSeq”, has been constructed to import serial bioinformatics algorithms.

Current Projects: Platform Comparison via Errors in Variables Models with or without Replicates
Platform or instrument comparison is a critical task in many lines of research and industry. In biotechnology, for example, with the rapid development gene sequencing platforms – we now have the first and the next generation sequencing platforms, each with several brands manufactured by different companies, co-sharing the market – at the same time, the third generation sequencing method built upon the sequencing of a single molecule of DNA, has already emerged. An accompanying critical task for the statisticians is how to best compare and combine results from different platforms. Previously, we have demonstrated the advantages of the errors-in-variable (EIV) model as an optimal instrument comparison and calibration device. However, one limitation to the traditional EIV modeling approach is its reliance on the availability of repeated measures of the same sample. Such replicates can be expensive and at times unattainable. Two methods by Wald (1940) and Kukush (2005) respectively are applicable for estimating the EIV model in the absence of replicates -- both relying heavily on the pre-cluster of data points. In this work, we aim to combine and improve these two methods through a better clustering strategy.
Gauging Biomarker Consistency between Different Measurement Platforms
With the rapid development of biotechnology, an increasing number of platforms for measuring gene expression levels are co-sharing the market – with the older technology such as the gene microarray being phased out, while the newer ones based on the RNA sequencing (RNAseq) being brought in, generation after generation. A crucial question to the entire biomedical community is whether biomarkers detected through these different platforms are consistent or not? In this work, we present a theoretical framework on biomarker consistency study based on the errors in variable (EIV) model. First, we calibrate the measurements between two platforms through an EIV model featuring indices for the constant bias and the proportional bias. Subsequently we demonstrate how different biomarker detection algorithms including the fundamental fold change and Z –test, T-test, will be influenced by such biases. Finally, we discuss strategies to combine measurements from different platforms for better biomarker detection.

Channel assignment in 802.11n WLAN
We study how to assign channels to APs in 802.11n WLANs, focusing on the new challenges from the 802.11n standard. We first introduce a throughput estimation model. Based on the model, we propose a distributed channel assignment algorithm, in which APs update their channels iteratively to maximize local network throughput. Simulation results show that the proposed algorithm can greatly improve network throughout.
