Research Interests

As can be seen from my previous postdoc at the Jaeger Lab, I am interested in the production and analysis of large electrophysiology simulation and recording data sets (Gunay et al., 2008, 2009a). In the Prinz Lab, I am involved in several projects:

1. Calcium sensors for activity-dependent homeostatic regulation (ADHR)

   The pyloric network in lobster stomatogastric ganglion is remarkable in its capacity to tolerate changes in the environment while keeping its triphasic rhythm intact. The ADHR mechanisms thought to maintain this rhythm need to first sense the network activity levels. For this sensing mechanism, calcium influx has been a highly likely candidate. Therefore, we search for calcium sensors by studying the parameter space of single and multiple sensors across 20 million pyloric network models (Gunay et al, 2009b).

2. Drosophila motoneuron model to study Na channel splice variants

   Together with postdoctoral fellow Fred Sieling and undergraduate student Logesh Dharmar, we are building a conductance model of the Drosophila motoneurons. This involves collecting voltage clamp experimental data from outside researchers and fitting and tuning model parameters. The goal of this is to use the model to test the functional effect of the different Na channel splice variants found in embryonic and adult Drosophila.
