Zebrafish hydrodynamics and locomotion during predator-prey interactions

In my dissertation work in the McHenry Lab  I investigated the biomechanics of active pursuit in zebrafish and the escape strategy of prey fish. I used high-speed video and custom tracking software to visualize the kinematics of prey pursuit. By simulating a swimming fish, I could explore how different body motions affect the overall trajectory toward prey and uncover motor control strategies. This work led to insights about the role of intermittent locomotion in aquatic predator-prey interactions. I also developed a technique to record multiple types of photographic data using a single camera.

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.
