The Oracle Lab that I'm collaborating with has a budget for a summer intern to work on a fast solver for eigenvalue problems (specifically to do Java/Python implementation and testing on internal data). They typically hire graduate-level interns. So if we have a suitable student who is capable of implementing and can consult me during implementation, they will make an internship offer quickly. Please let me know and send resumes of potential candidates to me if we do have graduate students interested in it. International students may require extra time for applying for an OPT/CPT.
