Research Projects

Modern Transportation systems, such as automobiles and commercial aircraft, are becoming more reliant on computing based systems for controlling their operation. This aspect combined with the ever increasing connectivity to external environments, such as cell phones, laptops, the Internet, and other vehicles, provides the potential of a cyber attack to interfere with normal operations. We are investigating new protocols and developing new techniques to formally verify and model security aspects as these systems transition to new communication architectures

The rapid advancement of additive manufacturing (AM, a.k.a 3D Printing) raises concerns about its security. So far, two major security threat categories have been identified in research literature: (i) violation of Intellectual Property (IP) and (ii) sabotage (eventually, weaponization) of AM process. The ongoing projects aim to overcome challenges and develop solutions addressing both of these threats. AM security is a cutting-edge, highly interdisciplinary research field. Various aspects require knowledge in disciplines like cyber-security, CPS security, material science, and mechanical engineering.

The OmniSearch project is supported by an active NIH/NCI grant (U01CA180982). It aims to develop a semantic search tool to assist cancer biologists in unraveling critical roles of microRNAs (miRs) in human cancers in an automated and highly efficient manner. The project will handle the significant challenge of data sharing, date integration, and effective search in miR research in oncology. .

Itemset Tree is a data structure that, along with associated search algorithms, permits the ability to conduct targeted association mining. Association mining is a type of data mining that seeks to find correlations between multiple variables within a database. Current research efforts include improving the efficiency of targeted association mining and modifying the Itemset tree and algorithms to support advanced association and pattern mining.

Social media has become a much discussed source of information; however, much of the analysis tends to be along the line of trending topics and terms. There is a growing emphasis on extracting addition types of information from the media; we have been pursuing two different efforts. One deals with detecting emerging events such as bomb threats, fires, road accidents, and drug recalls; the goal is to detect these events (and track them) within one to three minutes of their initial mention. The second centers around detecting new adverse drug reactions by analyzing Twitter data. This requires temporal reasoning, graph analysis and the ability to filter out spurious drug and reaction relationships.

Action rules are constructs that provide guidance on what actions (i.e. changes to attribute values) should be made to convert a set of objects from an undesirable state to a more desirable state. For example, assume that you are seeking to determine what can be done to reduce the severity of traffic accidents. A potential action rule would state, if you add streetlights to a street with none, a significant number of accidents that result in severe injury would be reduced to accidents classified as minor. Current research includes the development of more efficient and effective algorithms for discovering action rules.

Contrast mining methods are designed to analyze data to discover patterns that occur frequently among one set of data objects, but relatively infrequently among other sets of data objects. These methods have been successfully used to analyze data for and in a wide variety of applications including change detection, object classification, and subgroup discovery. Designing efficient and effective contrast mining methods is challenging because of the time complexity of the problem. Current research includes the design and implementation of novel contrast mining methods for use in the context of high dimensional data and data streams.

Approximately 50 million people worldwide have epilepsy, making it one of the most common neurological diseases. To manage seizures, many patients require continuous use of medication. While helpful in managing seizures, the medication can alter the patients state of mind and reduce their quality of life.  We are investigating data-driven, theorem-based algorithms to accurately detect and predict seizures, with the aim to provide foundational tools for ambulatory treatment and assessment of patients who are affected by this ailment.  Our research uses novel feature analysis based on nonlinear time-delay embedding and is currently a semi-finalist project in INNOCENTIVE’s SUDEP Challenge.

In the realm of social robotics, JagBOT is designed to function as a mobile tour guide. With location and situational awareness, the intelligent system is able to interact in a variety of forms with human participants. This ability to use multiple sensors to create a signature for various points within an environment is a prime example of sensor fusion. Later work has begun to consider how JagBOT might be adapted to perform the functions of a flight attendant.

Continuing the work on Intelligent Mobile Agent, the potential attacks on the learning algorithms are considered. As fully and semi autonomous robotic systems are created, the ability to adapt will be critical and rely on continuous unsupervised learning. This learning algorithm can be vulnerable to external attacks in a variety of ways: (i) hardware, (ii) firmware/OS and (iii) application levels. Attacks at any level would pose a serious danger as these system can and will impact all aspects of our lives. Work focuses on how these threats  might occur, be detected, and ultimately prevented.

Using a small scale mobile robot (LEGO NXT) a limited environment is created using RFID tags as waypoints. The robots are equipped with RFID readers, XBEE wireless communication and other sensors for navigation. Using simple learning algorithms the robots navigate the grid and are used to demonstrate cooperative and adversarial strategies.
