ECE 498 LV  Network Science: Dynamics and Flow (Spring 2018)
Instructor: Lav Varshney (office hours, Tuesday 12:302:00pm, 314 CSL and by appointment)
Lectures: Tuesday and Thursday, 11:00am, 4070 Electrical and Computer Engineering Building
Adjacency matrix of C. elegans connectome (Varshney, et al., 2011)  Volume of taxi rides in Manhattan on average Tuesday at 4PM, March 2009, http://www.binaryspark.com/heytaxi  Backbone of the flavor network (Ahn, Ahnert, et al., 2011) 
By taking an engineering perspective on network science, we can address these problems; more traditional problems in communications, computing, and power; and more!
Catalog Description: Network science studies connections and flows among interacting objects, and the dynamic evolution of these structures. This course will cover the mathematics of networks, drawing on an emerging set of principles and techniques that originate in engineering theory, physics, biology, and the social sciences. The goal is to equip students with conceptual tools for understanding complex network systems. Examples taken primarily from neuronal, knowledge, and infrastructure networks.
Suggested Prerequisites: ECE 210, ECE 313, or their equivalents. Programming in matlab, python, or other similar computing languages.
Textbook: M. E. J. Newman, Networks: An Introduction, Oxford University Press, 2010. Note that further readings and lecture notes will be provided through the course website.
Grading: Homework [including data/programming assignments] (35%), midterm exam (20%), final exam (20%), group project [openended topics, written proposal, written report, and inclass conferencestyle presentations] (25%). Graduate students enrolled for 4 credits will complete an additional individual researchorineted assignment.
