About Kavita…

When did you know you wanted to study Computer Science?

I decided on majoring in Computer Science since high school but discovered my passion for computer science research during the completion of my undergraduate years.

Are you part of any labs, clubs or organizations on campus?

I am a member of the Cognition, Robotics, and Learning (CORAL) lab of Dr. Tim Oates.

What are you researching for your thesis?

My research goals are to provide assistance and increase independence for people with disabilities using machine learning, artificial intelligence, and robotic technologies to improve their quality of life. In particular, my research is focused on path planning and the development of an accessible robotic interface to assist users with activities of daily living. For example, I am currently investigating the use of brain computer interfaces, speech recognition, and facial gestures to control an interface for repositioning the arms of disabled users to strengthen their muscles and relieve pressure on the joints.

I am extremely grateful for the research support of the Louis Stokes Alliance for Minority Participation Bridge to the Doctorate fellowship, National Academy of Sciences Ford Foundation Predoctoral fellowship, and National Science Foundation Graduate Research Fellowship. These fellowships are instrumental in facilitating my research career in many ways and making it possible for me to be one step closer to achieving my goals to assist people with disabilities and the elderly.

Have you had any internships? 

This summer I will begin an internship at Knexus Research to conduct artificial intelligence and robotics research.

Last summer, I participated in an AccessComputing Internship as a robotics interaction researcher working with Dr. Tim Oates. I implemented an accessible web interface to control a simulated robotic hand using WebGL. I also designed an interface with 3D graphical models, animations, and special effects using Blender and JavaScript.

I have also interned at IBM business consulting services and the University of Maryland School Of Medicine in the past.

What are your plans after graduation?

After graduate school, I plan to be a full-time researcher. I hope to advance technology development and increase diversity as a leader in computing, accessibility, and robotics.

What is your dream job?

In my dream job, I want to emphasize the importance of an inclusive environment for all by conducting research in academia or the industry. I want to increase the active participation of underrepresented minority groups in the community locally, nationwide, and internationally via research, especially people with disabilities, in order to improve their quality of life.

On UMBC and CSEE…

Why did you choose UMBC?

I chose UMBC for my graduate studies because I valued the more one-to-one teacher-student interactions compared to other colleges in Maryland, the size and accessibility of the campus was not too big or too small to accommodate my needs with a disability using a wheelchair, my positive experience in the Meyerhoff Scholarship Program as a UMBC undergraduate, and because I strongly believe that UMBC nurtures an environment for high-quality research and development in technology.

What was your first impression of UMBC?

I was on the UMBC campus during the Meyerhoff selection week for the first time. I was very impressed with the diversity of people from many different cultures and backgrounds all come together for the common goal of succeeding and pushing each other to succeed at UMBC. A diverse environment offers not only a greater learning experience, but also a greater social experience.

I love the positive energy of the campus. I always will remember the first time I heard our college president Dr. Freeman Hrabowski's favorite words by Langston Hughes, "Hold fast to dreams, for if dreams die, life is a broken winged bird that cannot fly." Those words broadened my perspective and gave me the confidence that success was guaranteed with hard work and sincerely giving your best efforts.

What was your first Computer Science Course?

My first computing course was CMSC 104: Problem Solving & Computer Programming with Dr. Chintan Patel.

What was your favorite Computer Science Course?

My favorite and recommended undergraduate courses are:

• CMSC  451: Automata Theory and Formal Languages that helped me understand the theoretical principles of Computer Science.
• CMSC  437: Graphical User Interface Programming gave me a perspective on the development of creative interfaces with a focus on the front end-user.
• CMSC  466: Electronic Commerce Technology provided me an opportunity to appreciate web technologies and applications for purchasing items online and understand the infrastructure of online shopping sites, such as Amazon and eBay.

My favorite and recommended graduate courses are:

• CMSC  601: Research Skills For Computer Science taught me how to thoroughly plan a research project and perform a literature review.
• CMSC  679: Introduction to Robotics presented an avenue to design, construct, program, and control an actual, real robot in the class project and learn about the latest robot technologies.
• CMSC  661: Principles of Database Systems offered a practical perspective of real-life data management techniques and procedures for maximizing efficiency.

What do you like about the Computer Science and Electrical Engineering (CSEE) Department?

The Computer Science and Electrical Engineering Department is a positive place filled with wonderful professors that are very devoted to their students and really want students to learn. Everybody in the department is very passionate about academia and research.

How would you describe the professors in the department?

Professors are well-experienced, friendly, supportive, and leaders in their field. They are always willing to spend time with the students to help them grasp the material and eager to offer advice.

What advice would you give to incoming graduate students?

Computing is a promising field. Technology keeps growing every year so computer science jobs will always be in high demand. If you’re interested in a career in computing, take some time to figure out and plan your goals and discussed them with your professors, seniors, and peers in the department. Also, learn about the research work of those around you to learn from them and share your own experience with them so they can also learn from you.

Multi-antenna Spectrum Sensing: From GLRTs to LMPITs

Dr. Javier Via
University of Cantabria, Spain

2:00pm Friday 22 June 2012, ITE 325b

Spectrum Sensing represents one of the critical aspects of the Cognitive Radio paradigm, where spectral monitors need to determine the presence or absence of primary users under very low SNR conditions. In this talk, we briefly revisit the main spectrum sensing techniques, with special emphasis in multi-antenna detectors, and we will see that the heuristic eigenvalue-based approaches can be outperformed by making use of some important results in the hypothesis testing literature. In particular, we will consider two related hypothesis testing problems, and derive the locally (under low SNR) best detectors among those preserving the problem invariances. Interestingly, this challenging task can be accomplished thanks to Wijsman's theorem, which allows us to obtain the optimal test statistic without the explicit knowledge of the maximal invariant distributions.

Javier Vía received his Telecommunication Engineer Degree and his Ph.D. in Electrical Engineering from the University of Cantabria, Spain in 2002 and 2007, respectively. In 2002 he joined the Department of Communications Engineering, University of Cantabria, Spain, where he is currently an Associate Professor. He has spent visiting periods at Stanford University, Hong Kong University of Science and Technology, and more recently at SUNY at Buffalo. Prof. Vía has actively participated in several European and Spanish research projects. His current research interests include hypothesis testing and spectrum sensing, quaternion signal processing, and financial engineering.

An Operational Study of DNSSEC and its Practical
Application in Establishing a Secure PKI Framework

Colin Roby

4:00pm 19 June 2012, ITE 325b

With the recent completion of signing the DNS Root and various TLD (top level domain), DNSSEC is gradually progressing towards an internet-wide adoption. The extension of DNSSEC security measures addresses many of the security flaws plagued the underlying DNS architecture since its inception. Once widely deployed, DNSSEC will pave the way for extending security service to a wide range of applications. This study focuses on the practicability of current iteration of DNSSEC implementation. Through a virtual network configuration which mimics a typical corporate environment, we explore viable options to establish a secure PKI framework based on DNSSEC in spite of its current limitations. In this endeavour, we propose a simple yet effective method to combine a corporate existing LDAP based directory service with DNSSEC to form a PKI key exchange infrastructure – one which is intuitive to administer and easy to scale to any large corporate network. We demonstrate the advantage of such a PKI framework in one area of its application – the common use of email. Using a prototype email client application, we illustrate how such a framework can promote and facilitate a more secure email system in terms of authenticity, integrity and confidentiality.

UMBC's sister school to the south, the University of Maryland, College Park just announced plans for a new honors program in Cybersecurity called Advanced Cybersecurity Experience for Students (ACES) that they will debut in Fall 2013.

Unlike UMBC's graduate Cybersecurity program, ACES is designed for undergraduate students from a range of majors including Computer Science, Engineering, Business, Public Policy, and the social sciences, says a UMD press release.

The Northrop Grumman corporation is supporting the program with a $1.1 million grant. They'll also supply guest lecturers and internship opportunities for students who want to gain some industry experience. The curriculum features courses like cybersercurity forensics, reverse engineering, secure coding, criminology, and law and public policy. Designed to graduate about 45 students per year,  the program's aim is to encourage creative problem solving for Cybersecurity problems of the future, says a Baltimore Sun article.

Sound good? Undergraduates at UMBC may eventually be able to take advantage of College Park's new program. According to the UMD press release, over the next few years, College Park hopes to have universities across the University System of Maryland participate in the program through distance education programs, online course offerings, and competitions.
