Burak Güçlü received a B.S. degree in Control and Computer Engineering from İstanbul Technical University in 1997 and an M.S. degree in Bioengineering from Syracuse University in 1999. He worked as a teaching assistant for Biocontrol Systems and Bioinstrumentation Laboratory. He recorded from tactile nerve fibers of cats at Institute for Sensory Research (ISR) in Syracuse, New York. In 1999-2000, Dr. Güçlü attended University of Michigan in Ann Arbor and studied sensory systems of insects at Advanced Technology Laboratories, and of guinea pigs at Kresge Hearing Research Institute using multi-electrodes. Then, he returned to ISR and worked on mathematical modeling of the sense of touch. He performed psychophysical experiments on human subjects and tested computational models. He received his Ph.D. degree in Neuroscience from Syracuse University in 2003. During his post-doctoral year, he studied species-specific vocalizations and recorded from the prefrontal cortex of awake-behaving macaque monkeys in the medical school of University of Rochester. Dr. Güçlü has been with Biomedical Engineering Institute of Boğaziçi University since Summer 2004 and works in several project grants. He also teaches in the Molecular Biology and Genetics Department of Istanbul Technical University.
