B. RESEARCH ACTIVITIES

RESEARCH STATEMENT

My current research efforts are mainly in the transition from data to semantics, viewed from both theoretical and pragmatic perspectives and directed to a variety of areas such as databases, artificial intelligence, cognitive science, human-computer interaction, information retrieval and integration, intelligent geographic information systems (GIS), image processing, pattern recognition, semantic web, text processing, and PDE-based modeling of complex systems. I am able to collaborate with individuals working in any of these areas. The focus of my research is called data semantic associative analysis and synthesis .
    My long-term goal is to develop theories and tools embedded into a working computer system to estimate meaningful content of raw information. In the following, I briefly describe past, current, and future research projects, which are strongly motivated by industrial applications and by development of emergent educational programs in computing and information sciences.

C. TEACHING ACTIVITIES

TEACHING PHILOSOPHY

My teaching philosophy is student-centered and oriented to provide simple and clear ideas of the course to an average student. I use a number of complementary approaches in my presentations, such as writing on slides, drawing schemes and figures, classifying different cases and types, using analogies, simplifying arguments, etc. I introduce several state-of-the art technologies such as real-time simulators, quick-time movies, interactive web surveys, and modeling examples during lecture hours and beyond.
     My role as an instructor is to develop, adopt, and implement the course program, to give a series of lectures, to supervise performance of teaching assistants, to prepare home assignments, tests, and exam papers, to maintain web pages of the course, and to handle student questions and problems. I pay special attention to the web-based form of the educational program, interactive lecture notes, interactive simulation software, online grade keeping software, and interactive student research projects. The idea is to stay in frequent touch with my students. This teaching approach produces favorable feedback.
     I give individual attention to students during office hours and beyond. My experience shows that the students' development is variable and that students can reach a high level of performance due to the teacher's involvement. I also encourage students to approach advanced problems, which I post on web pages, designed for this purpose. These problems help to define the student research. I consider my teaching goals accomplished if the majority of students reach a clear comprehension of the course, become used to solving typical problems and examples, and successfully pass assignments, tests, and exams.
     I enjoy working with students and consider teaching to be an important part of a professor's job. While research papers become subjects of studies of the experts, the teaching materials ought to be clear and understandable to a wide range of undergraduate students. I am sure that teaching supports a professor's research as well, encouraging clearer presentations, vivid examples, explanations, and illustrations of his or her ideas. Thanks to my students, my teaching skills are improving year-by-year and I am pleased to see a positive feedback from them in the course evaluation surveys.
