International Research Experiences for Students (IRES)

IOS would like to bring your attention to a program in NSF’s Office of International Science and Engineering (OISE) that supports international research and research-related activities for U.S. science and engineering students. The International Research Experiences for Students (IRES) solicitation, 20-598, describes two tracks and details how to apply to the program. 

IRES – Track I: IRES Sites (IS) projects engage a group of undergraduate and/or graduate students in active, high-quality collaborative research, in principle at an international site with mentorship from researchers at a host lab. IRES Sites must be organized around a coherent intellectual theme that may involve a single discipline or multiple disciplines funded by NSF. Proposals for Track I are due on September 21, 2021.

IRES – Track II: Advanced Studies Institutes (ASI) are intensive short courses with related activities that engage advanced graduate students in active learning and research at the frontiers of knowledge. ASIs typically range in length from ten to twenty-one days and, in principle, must be held outside the United States. ASIs must have a compelling rationale for their international location and should involve distinguished active researchers in the target field from the U.S. and abroad. ASIs should enable students to develop skills and broaden professional networks, leveraging international participation and complementary resources (expertise, facilities, data, field site, etc.) for mutual benefit. Proposals for Track II are due on September 28, 2021.

Full Proposal Deadlines: September 21, 2021 (Track I) and September 28, 2021 (Track II)

Program Virtual Office Hours
The IRES Program Team is also hosting a series of Virtual Office Hours aimed at giving potential PIs an opportunity to ask questions.  There will be one session per week for 9 weeks, starting July 19 and ending on September 13, during which any questions about the program can be asked and discussed. Session dates and times are outlined below. Please feel free to attend the session which best fits your schedule. The link will be the same for each session.

Upcoming Session Dates: August 30, September 6, 13, 2021, 11:30 am – 12:30 pm
