Visuomotor Control in Fish Predator-Prey Interactions

For my dissertation work in the McHenry Lab  I am interested in the strategy predatory zebrafish use when attacking prey. Prey capture is a visually mediated behavior and is subject to constraints imposed by the locomotor system. By assessing the role of vision on locomotor performance during a predatory encounter I am beginning to uncover the control system used by predators. Modeling the visuomotor control system will provide a means to test alternative control strategies. This will allow us to ask whether the zebrafish is performing optimally under its constraints.

Modeling Blood Pressure Dynamics 

Presenting at JMM in Boston.

During the summer of 2011, I participated in the NCSU REU program. I was part of a group of six students working under the guidance of Dr. Mette Olufsen. The goal of our research project was to develop a mathematical model of the circulatory system and to effectively model the autonomic response that regulates blood pressure during head-up tilt. We used numerical methods to estimate a subset of model parameters from patient specific data. This research has the potential to become a tool for personalized diagnosis of blood pressure regulation disorders.
