Dr. Sheyum Syed, Assistant Professor in Physics, will present a seminar entitled, "Insights into Drosophilia Sleep Architecture" to the Department of Biology on Monday, October 7, 2013 in Cox166 from 12:20-1:20pm. His research area is biological physics with the aim of understanding complex behavior as it arises in the natural world. The complex behaviors they are interested in include locomotion, sleep, feeding, and collective phenomena that may arise from interaction among multiple individuals. Dr. Syed's lab focuses on the model organism Drosophila melanogaster to understand these behaviors and take advantage of its built-in timekeeper, the circadian clock, as a starting point in tracing the molecular and neuronal pathways that generate complexity in this 'simple' animal. The laboratory utilizes time-lapse fluorescence imaging to detect molecular kinetics in individual fruitfly cells and combines infra-red and video tracking technologies to capture dynamics of behaving flies. In this talk, Dr. Syed will focus on their recent findings on Drosophila sleep architecture. Specifically, he will present their motivation behind studying the probability distribution of fly sleep and wake epochs and show results of attempts at constructing statistical models that mimic wild-type and mutant fly data. The talk will end with implications of these findings to our understanding of how sleep is likely regulated at the molecular level.
