HOPOS 2024 accepts two types of submissions: contributed papers and symposia, which are topical collections of 3-4 papers intended to be presented in a single session.

Those who have a contributed paper accepted for the program will be scheduled to speak during a 1.5-hour or 2-hour session, and will have 20 minutes of speaking time, followed by a 9-minute question-answer period. Those who are part of a symposium will be scheduled to speak during a 1.5-hour or 2-hour session, depending on whether the symposium includes 3 or 4 papers. The specific format of the symposium is to be determined by the symposium organizer, but we encourage choosing a format that allows each speaker to have at least 20 minutes of speaking time.

To submit a proposal, contributors will need to create and account on the HOPOS 2024 website. Proposals for contributed papers and symposia should be prepared for anonymous review. The deadline for submission is 11:59 PM (PDT), October 1, 2023.

Proposals for contributed papers should include:

• Title of the paper.
• Abstract of the paper (maximum 500 words).
• Contact information for all co-authors.

Proposals for symposia should include:

• Title of the symposium.
• Symposium summary statement (maximum 500 words).
• Titles and abstracts of the papers (maximum 500 words for each paper).
• Contact information for all symposiasts.

In addition, all contributors will be asked to respond to surveys regarding possible online participation and the HOPOS mentorship program.

A person can appear as a speaker on the congress program no more than once, and additionally, a person may have a speaking role in no more than one proposal. (A person may submit one contributed paper proposal and be part of one symposium, but if both get accepted, the contributed paper will be automatically dropped).
However, a person may appear as a co-author on multiple contributed paper/symposia (again, as long as they do not appear as a speaker on multiple contributed paper/symposia). If you are submitting a proposal with a co-author, and your co-author intends to submit a different proposal on their own or with other co-authors, we suggest that you omit the co-authors name from the first submission. We will be able to add the co-author's name if/when the proposal is accepted.
If you have questions about this issue, please contact webmaster@hopos.org
