Alfred W. Hubler received his diplom in 1983 and Ph.D. in 1987, summa cum laude, from the Department of Physics, Technical University of Munich, Germany. After a postdoctoral fellowship at the University of Stuttgart, Germany, he came to the University of Illinois as a visiting assistant professor in 1989, and became assistant professor in 1990. Later that year, he also became the associate director of the Center for Complex Systems Research at Illinois, of which he is now the director. Professor Hubler served as a Toshiba Chair Professor at Keio University, Tokyo, in 1993-94. Since beginning his thesis research, Professor Hubler has worked on nonlinear dynamics and has investigated a broad range of nonlinear phenomena. He is primarily a theorist, but he is also experienced in and capable of guiding both experimental and computational work. He has made solid contributions to the study of the chaotic dynamics in classical systems, both in idealized physical models and in engineering systems. He has been a pioneer in several important recent developments in nonlinear science research, including the control of chaos, the resonant coupling of nonlinear oscillators, and resonant stimulation and novel spectroscopies in nonlinear systems. Professor Hubler was among the very first to recognize that seemingly erratic, random motions associated with deterministic chaos could, in fact, be controlled, and that "chaotic" systems could be more "flexible" than systems undergoing more regular motion. A skillful and committed teacher, Professor Hubler has also creatively applied the principles of nonlinear resonance to develop an intuitive, interactive web-based software package used to teach a variety of university science courses, at Illinois and around the world. Dubbed " CyberProf," the software analyzes student homework problems in real time and provides meaningful, intelligent, individualized feedback to each student.
