About

I work on AI agents at Google Cloud AI, focusing on how to evaluate them and make them faster, more reliable, and less expensive to run.

Across software and physical models, I’m interested in what measurements can tell us, and where a prediction stops being useful.

How far ahead can we predict a chaotic system?

Can four noisy position measurements predict which particles will escape? I tested this in a system with three exits, withholding both the energy and starting region from each predictor.

Short position histories helped at nearby forecast times. Later gains and the benefit of adding an instability measure remained unresolved.

Three simulated Hénon–Heiles paths at energy 0.18 wind through the central region before exiting upward in blue, lower-right in gold, and lower-left in coral. Circles mark their starting positions, and faint curves mark potential-energy contours. These are illustrative trajectories from the study, not a chart of prediction accuracy.Three simulated Hénon–Heiles paths at energy 0.18 wind through the central region before exiting upward in blue, lower-right in gold, and lower-left in coral.

Illustrative speed
Three recorded simulation paths at the same energy, each reaching a different exit. Faint lines show potential-energy contours. These paths illustrate the system, not prediction accuracy.

Strust

Rewriting a program is easier than knowing whether it still behaves the same. I built Strust to run COBOL programs and their Java replacements on shared inputs and compare the results.

Outside of work I play cello, backpack, write, and release jazz and blues recordings as Copperbelt. I also share photographs from my travels.
