About

I am a senior robotics and robot learning engineer specializing in manipulation, reinforcement learning, imitation learning, motion planning and control. I work end to end across perception, planning, control, ML, simulation and software infrastructure, and I have taken systems from research prototypes to deployed production machines.

Today I am based in Zurich at Witty Machines, where I own the robotics software stack of production dual-arm picking and packing systems. Before that I led manipulation at Floating Robotics and held a postdoctoral and assistant professor position at the University of Pisa, where I earned my Ph.D. in Robotics (with honors) and spent time as a visiting researcher at Stanford.

I am also co-founder and scientific advisor of XStar Motion, a start-up developing industrial motion-optimization algorithms.

XStar Motion

My research on optimal trajectory planning led to XStar Motion, a start-up that aims to transform the way the motion of machines is planned.

We developed X*Solve, an algorithm that computes the optimal trajectory along a working-cycle path while respecting the machine's velocity, acceleration and jerk limits. It runs online, delivering optimized references at the controller frequency, and integrates with both robots and CNC machines.

XStar Motion combines 20 years of automation expertise from EUROSOFT with cutting-edge research in motion planning and control from the University of Pisa. Today's AI theory, algorithms and computing power make it possible to plan the motion of every machine to exploit its full potential, and to update it autonomously for every task.
