Hard Surface and Organic Rigging
Left Atrial Appendage Closure Device
When the heart is in atrial fibrillation, blood clots can form in the left atrial appendage (LAA). If a portion of a clot dislodges and travels through the bloodstream, it can lead to serious complications such as stroke. To help prevent this, a left atrial appendage occlusion (LAAO) device is used to seal the LAA.
I rigged this model for use in a VR simulation teaching the placement of an LAAO device in a beating heart. The instrument was designed to move flexibly within blood vessels and the heart while collapsed and to deploy once positioned within the LAA.

ROSA Robotic System
In this project, I rigged and animated an articulating robotic system used in knee replacements. The robotic arm operates with seven degrees of freedom. I developed the joint hierarchy and control system to provide FK control over the arm, enabling precise positioning relative to knee anatomy. The completed rig and animation are used in Unity within an interactive procedure.

Transesophageal Echocardiography Probe
Transesophageal echocardiography (TEE) is an imaging technique where a long, flexible probe is guided down the esophagus to capture ultrasound images of the heart.
I rigged this model to achieve realistic deformation of the TEE probe for use in Unity. The rig allows for smooth bending along the esophagus and both anterior-posterior and lateral deflection of the probe tip. After completing the rig in Maya, I implemented the probe motion and tip deformation within Unity to provide the user with a realistic simulation of TEE imaging of the heart.

Patient Hospital Bed
I created a joint hierarchy and control rig for a hospital patient bed to allow for easy positioning using standard bed controls, including height, incline, tilt, head raising, and guardrail placement. This rig was created using driven keys, constraints, and direct connections within the Node Editor in Maya.

Animation
Shining a Light on Phototropism
Phototropism is the ability of a plant to grow towards a light source. This animation is designed to explain the differential growth that causes a plant to bend towards the light to a high school audience. This animation started as an original script and storyboard. The modeling, texturing, lighting, and rendering were completed in Cinema4D. Post effects were applied in Adobe After Effects.

PulseFlush: A Novel Pulsatile Syringe
This animation was created in partnership with a student group at the Johns Hopkins Center for Bioengineering Innovation and Design to explain the problems with current syringe flushing and to promote a novel syringe design that creates pulsatile flow. The script was written and edited in collaboration with the student group, storyboarding was completed and an animatic created.

Indications for Malyugin Ring: Intraoperative floppy iris syndrome (IFIS)
This is a simple motion graphic depicting the symptoms of intraoperative floppy iris syndrome, or IFIS. This animation could be included on a lecture slide and spoken to, or it could be included as part of a larger animated sequence with narration. The graphic style emphasizes the main characteristic of each symptom so a viewer can easily understand the differences between them.
