Interested in doing research with us?

How best to get in touch depends on your situation. Are you…

  1. Currently at UCR?

    If you are an undergraduate or MS student at UC Riverside and would like to get involved in research, email Prof. Saragadam with your CV, transcript, and a short note on which of our projects interests you and why.

  2. Applying to UCR?

    If you are a prospective PhD student, apply through UCR Graduate Admissions to the ECE or CSE program and mention Prof. Vishwanath Saragadam as a potential advisor in your application.

    Prospective postdoctoral researchers should reach out directly via email.

  3. External to UCR?

    If you are interested in collaborating or visiting, please reach out via email with a clearly scoped idea and a note on your prior work in the area.

We read every message, but due to the volume of inquiries we may not be able to reply to everyone.
