MATLAB Shape Optimization for Ball Simulation

I'm looking for an experienced simulation engineer to help with a specific task. The project involves simulating a 15cm ball rolling around a plastic unit using MATLAB. The goal is to optimize the shape of the plastic unit so the ball does not roll off.

Key Requirements:
- Simulate ball motion using MATLAB
- Focus on shape optimization to keep the ball on
- Work within defined geometric constraints

Ideal Skills:
- Proficiency in MATLAB
- Strong background in shape optimization and motion dynamics
- Experience with geometric constraints in simulations

Please provide samples of previous similar work.
