Coronary Stent Design and Analysis
My team and I developed various stent configurations using SolidWorks and Finite Element Analysis to address restenosis. We modeled various stent configurations and evaluated their mechanical performance under physiological conditions. Through simulating multiple materials, designs, and sizes we were able to suggest designs that exhibited the most optimal balance of yield strength and durability. We balanced different meshing methods, factory of safety, Von Mises stress, displacement, and modeled stress v strain curves.
I always wanted to familiarize myself with manufacturing and CAD modeling software, and I was happy to work on one of the medical devices that inspired me to pursue BME. I really enjoyed researching this and would love to revisit this in the future.

Experimentation with meshing taking multiple hours :0
Microneedle Model for Insulin Delivery
I developed a 2D COMSOL model to simulate the diffusion of insulin through microneedle arrays into the dermis and epidermis. By fine-tuning initial concentration and therapeutic dosage, I ensured efficacious concentrations of insulin within clinical use. My analysis included generating heat maps and concentration profiles, optimizing microneedle geometry, and proposing improvements for more accurate in vivo simulations.
COMSOL was quite a difficult program to learn from the ground up, and I was met with a slew of problems. It took me at least a week of trouble shooting to get my fluids to flow in the right direction. I reconstructed my model at least 10 times over multiple weeks, and some of the problems ended up being the easiest fix of ticking a single box.

Diffusion of Insulin in Single Microneedle over 150s
Concentration Results
This graph displays the concentration at different time intervals, as you move downwards through the needle vertically. I cut the model vertically, and modeled diffusion down the cut. Different lines display different time intervals of insulin diffusion.
The most efficient transfer of insulin over time was through an array of 256 needles with the measurements and parameters listed in the table. This project was quite tedious at times, but very rewarding. It took me a few weeks of research, then a few additional weeks to learn COMSOL and model the array. Overall, quite enjoyable and provided me some very satisfying visuals!
Finger Prosthesis Assembly
This was one of the first assembly I had ever constructed from scratch. I modeled all the pieces I needed, added variable lengths and sizes, then created the assembly. I want to work with prosthesis in the future, so I wanted to try and model something at my skill level at the time.
I want to revisit this project when my 3D CAD skills are significantly improved and can create something more high fidelity! I’m quite fond of this project, regardless of how rudimentary the assembly is. Very fun!
