The Hybrid Systems Laboratory (HSL) at the Department of Computer EngineeringUniversity of California at Santa Cruz, focuses on the analysis of hybrid dynamical systems and the design of hybrid feedback control algorithms. The research approach is mainly theoretical with numerical validation via simulations (though experimental validations of findings at an on-site testbed are performed at times). Particular emphasis is given to dynamical systems with nonlinear hybrid dynamics, cyber-physical systems, and feedback systems with decision-making strategies emerging in the areas of robotics, aerospace, power systems, and biology.

Interest in Our Research?

Thank you for your interest in the research at the Hybrid Systems Lab!

If you would like to be consider for a position in our lab, I suggest the following:

  1. Read the first 15 pages of the article [34] at the "publications" page of our website ( to get a better idea of our work.
  2. Read the section "Simulation in Matlab/Simulink" of article [34].
  3. Download the simulator files in the "software" page of our website ( and simulate a hybrid system that you are interested in.

You are also encouraged to read other papers, project descriptions, etc. posted at our website.

Then, email me a report in pdf format with the following sections:

- A one-page summary describing your interests on theoretical research (call this section "Research Interests").
- A one-page summary describing the relationship of your interests and the research at the Hybrid Systems Lab, and your initial ideas on the problems you would like to work on (call this section "Preliminary Research Plan").
- A detailed description of the system you simulated in 3) above, including simulation results and an explanation of those simulation results (call this section "Initial Results").

- A description of your qualifications. Please include a list of publications, reports, monographs, etc. you have written and attach to your email copies of two representative ones (call this section "Qualifications").

Your submission will be reviewed and a response will be provided as time allows.  Thank you in advance for your submission.
