Requirements and Guidelines for PhD Thesis Defense

MedE Requirements

The Ph.D. thesis defense exam is conducted by a committee that is set up by the student and approved by the option representative. The committee should be made up of minimum of 4 members and at least three of the committee members must be Caltech Faculty affiliated with Medical Engineering. The committee must include the adviser, but another member of the committee must be selected as chair. The committee chair must be a Caltech Professorial faculty member.

MedE Guidelines

  • Students should allow 2 hours for the whole defense process.
  • Without interruption, the continuous presentation should be about 40-50 mins.
  • Depending on communication skills, content, etc. 40-50 slides are suggested (but, no matter what, finish your presentation within 50 mins without interruptions).
  • It's highly recommended that students rehearse his/her presentation before real defense.

Suggestions for Zoom presentation based on a past Zoom Defense

1. The host is able to mute everyone, but still asked people to mute themselves. Everyone muted themselves and were very respectful of that.

2. The presentation was given using PowerPoint and sharing the screen.

3. Screen recording was used to record the audio and video of the presentation.

4. Questions and answers were facilitated by the advisor.

  • Those with questions were asked to type questions into the chat window and send it out to everyone. The advisor would then moderate the Q&A portion of the defense. This way, there was only the PhD candidate and the advisor speaking while everyone else stayed on mute.

5. There was a separate zoom link created for the private session of the defense that only the committee had access to. This way the public portion could end in roughly one hour and the private session could continue without interruption.

Caltech Defense Requirements

Final PhD Defense:

Final exam committee - Students should log on to REGIS to schedule the final thesis exam and select an approved committee for the defense. An approved committee consists of four total members, three of whom must be current Caltech professorial faculty. The chair of the committee is a professorial faculty member distinct from the advisor.

A requirement of all Ph.D. programs at Caltech is that the student must prepare and successfully defend a dissertation, known as a "thesis". Caltech theses have a common format and there are regulations regarding the contents and final submission to CaltechTHESIS. Students are responsible for familiarizing themselves with the regulations, following the recommended format, carefully proofreading the thesis, meeting deadlines, working with their adviser and thesis committee to schedule the final defense, providing timely copies of the thesis for review, and making requested revisions. Each thesis must be submitted to the Graduate Office for proofreading no less than two weeks before the scheduled exam date. In order to complete the Ph.D. degree requirements, the student must not only pass the oral thesis defense but also upload a final, approved version of the thesis to CaltechTHESIS as well as the necessary steps as described in the regulations and checkout procedures. Official certification of degree completion will be provided once all the steps have been completed and Institute approvals have been noted in Graduate Degree Progress in Regis.

The Caltech Library has a comprehensive website with instructions for submitting the final thesis, Theses Templates, and tips for preparing the thesis.

In addition to the thesis, each Ph.D. candidate must complete the following forms:
