Subject: Call for Nominations: 2026 Rising Stars in Computational & Data Sciences
We are seeking nominations for the 2026 Rising Stars in Computational & Data
Sciences Workshop to be held April 7-8, 2026, at the Santa Fe Institute in
Santa Fe, NM. Rising Stars is an intensive workshop for graduate students and
postdocs who are interested in pursuing academic and research careers.
Originally launched at MIT in 2012, Rising Stars events have been hosted in
many different fields at institutions across the world. UT Austin's Oden Institute
for Computational Engineering and Sciences, the Santa Fe Institute, and Los
Alamos, Lawrence Livermore, and Sandia National Laboratories are proud to
partner to host the seventh Rising Stars workshop in Computational and Data
Sciences, with a focus on early career researchers in computational and data
sciences. Previous workshops have been held in 2019 (Austin), 2020 (virtual),
2022 (Albuquerque), 2023 (Austin), 2024 (Austin), and 2025 (Austin).
We invite nominations for outstanding candidates in their final year of PhD or
within three years of having graduated and not yet in a tenure-track faculty or
permanent staff position. Approximately 30 participants will be selected to
come for two days of research presentations and interactive discussions about
academic and research careers, with financial support for travel provided.
Nominees are considered based on their technical merit, and their technical
and service leadership.
Nominations require (1) a letter of nomination and (2) the nominee's two-page
resume. Nominations are due January 30, 2026 and should be submitted at:
https://app.smartsheet.com/b/form/019b37488a617a64a42d102a41da308e

The list of hotels is also on the www.saintgironsconference.eu web
(under Venue and Lodging).
As in previous conferences in Saint Girons, there are a limited number of
rooms in Saint Girons close to the conference, and you are strongly advised
