Hi, my name is

Saimai Lau.

Robotics, Controls & Human-Centered Systems

M.S. student in Mechanical Engineering at Stanford University. I develop autonomous and interactive robotic systems through control theory, state estimation, and hands-on experimentation — and apply the same tools to biological systems, from gut microbial dynamics to inflammatory disease treatment. My long-term goal is to advance human-centered robotics for physical assistance, movement augmentation, and rehabilitation.

About Me

Saimai Lau profile picture

DiDi (~2008–2023), my best friend.

I am a Master’s student in Mechanical Engineering at Stanford University, advised by Prof. Allison Okamura (faculty) and Prof. Michaelle Mayalu (research). I completed dual B.S. degrees in Mechanical Engineering (Robotics & Controls) and Mathematics (Applied Science) at UC San Diego in three years, graduating Magna Cum Laude with a 3.95 GPA.

My research interests lie at the intersection of control theory, state estimation, and physical human-robot interaction. I am particularly drawn to biomechatronics, haptic feedback, assistive/rehabilitation robotics, and multi-agent systems. I am currently applying to PhD programs for Fall 2026.

Born and raised in Hong Kong, I speak Cantonese and Mandarin natively alongside English. Outside of research, I rebuilt my secondary school’s robotics team and established its first STEM club and makerspace.

Research Experience

Graduate Researcher - Mayalu Lab
Sep 2024 - Present

Stanford Mechanical Engineering – Advisor: Prof. Michaelle Mayalu

  • Co-authored “Optimal Control Strategies for Cutaneous Inflammatory Disease Treatment Using a Predictive Multi-scale Model,” accepted at American Control Conference (ACC) 2026.
  • Designed and implemented a Pontryagin-based hybrid optimal-control framework combining impulsive phototherapy with continuous probiotics for a 5-state ODE model of gut-skin-immune dynamics.
  • Currently building a species-level gut microbial ODE model from cross-sectional shotgun metagenomics data using MICOM flux-balance analysis to infer growth rates, Dirichlet synthetic sampling for data augmentation, and Hill-function ODE fitting — replacing the hand-tuned lumped model from the ACC paper with a data-driven plant model for optimal treatment design.
Undergraduate Researcher - MURO Lab
Jun 2023 - Jun 2024

UC San Diego – Advisor: Prof. Sonia Martinez

  • Implemented distributed MEKF-SLAM and cyclic-pursuit coordination algorithms on TurtleBot4s using ROS 2, LiDAR, IMU, RGB-D cameras, and Marvelmind UWB beacons.
  • Developed the ROS 2 implementation for distributed Gaussian Variational Inference (DGVI) mapping on multi-robot teams.
  • Co-presented poster: “Distributed Variational Inference for Online Supervised Learning” at the 2023 Southern California Robotics Symposium, UC Irvine.
Undergraduate Researcher - Boomerang Aerodynamics Research
Jan 2023 - Jun 2024

UC San Diego – Advisor: Prof. Prasad Gudem

  • Derived analytical expressions for lift, drag, and torque in tribladder boomerang designs with systematic wing offsets.
  • Parametric CAD in SOLIDWORKS; field validation via UWB positioning and drone-based 3D trajectory tracking.
