The Institute for Computational Engineering and Sciences (ICES) at UT Austin and Sandia National Laboratories (SNL) are partnering together to host Rising Stars in Computational and Data Sciences, an intensive workshop for women graduate students and early-career researchers who are interested in pursuing academic and research careers. The workshop will be held April 9-10, 2019 at ICES. We are seeking nominations for outstanding candidates in their final year of PhD or within three years of having graduated.

Applications for the Gene Golub SIAM Summer School are due February 8th! This year will focus on large-scale data analytics. The program is open to graduate students in the mathematical sciences and related areas. This summer school is taking place in the French Alps from June 17-30, 2019. I am one of the instructors along with Animashree Anandkumar, Haesun Park, Jack Poulson, and Costas Bekas. For the application, you need a cover letter, 2-page CV, transcript, and letter of recommendation from you advisor.
