+I recently finished my Ph.D. in physics at the University of Michigan and am about to head off to a postdoc at UC Irvine.  The title of my dissertation was "Understanding the interplay of structure and dynamics in neuronal networks", and much of my research has focused on questions in the field of neuroscience.  Networks are very important in this field as the brain is a prime example of a very complicated network.  Important features of neuronal networks are that the nodes (neurons) are dynamic due to the firing of action potentials, and the edges (synapses) are constantly evolving.  The main part of my dissertation focused on a new clustering algorithm that utilizes these neuronal dynamics to detect groupings of neurons with similar firing patterns.  I think that studying networks with dynamic nodes will become increasingly important as we try to apply network theory to more types of networks. Since neuronal networks can be viewed as time series of discrete events, I'd like to extend this line of thinking to types of networks outside of neuroscience, and I'm hoping that this workshop will be a good place to do so.
-I'm interested in learning more about techniques used to study complex systems in general, but specifically, I'm currently interested in the effects of structure on network dynamics and synchrony.  I'm also looking foreward to interacting with people from a variety of disciplines so that we can all learn from eachother and integrate new ideas into our current work.
+In addition to the algorithm development and subsequent data analysis, much of my time in graduate school was spent doing experimental work growing dissociated hippocampal cultures and studying how the underlying structure of these networks influences their dynamics.  I also spent some time doing computational modeling of epilepsy where I studied two coupled networks of neurons and looked at resonance and driving relationships between the networks as one network transitioned into seizure dynamics.  Although this was my first project as a graduate student, my new postdoctoral position will also be in the field of epilepsy research.  Network analysis is becoming increasingly important in epilepsy to study the initiation and propagation of seizures, so I'm quite excited to work in this area.

Hi everyone! I'm Sarah Feldt and I've just finished up my second year of the Ph.D. program in physics at the University of Michigan. Although my degree will be in physics, my research is best described as being in neuroscience.

My current research project investigates network dynamics and communication between two interacting networks of neurons. Through the use of computer simulations, I examine measures of phase synchrony within each network as well as between the networks to gain an understanding of the underlying dynamics. The collective signal of each network can be interpreted as an EEG recording, allowing for a comparison of this model with phase synchrony measurements currently used in seizure prediction.

My interests outside of the academic world include KU basketball (my undergrad was at the University of Kansas), baking, and hiking. I also play flute and piccolo in the U of M Life Sciences Orchestra and have the world's cutest kitten named Einsteinia. I'm very excited about getting to travel to Beijing this summer and meet all of you!
