Welcome to the Applied Mathematics Doctoral Seminar!
This is a weekly gathering where ideas converge, curiosity is sparked, and research leaps forward. Each semester, we bring together Georgetown’s students, faculty, and guest scholars to explore emerging topics that bridge theory and application: from partial differential equations and machine learning to optimal control, computational modeling, and beyond.
Whether you’re probing deep mathematical questions or translating theory into practice, this seminar offers an opportunity to sharpen your thinking, exchange insights, and find new directions for your work. Check the schedule below for upcoming talks; each is a chance to dive into cutting-edge research, connect with speakers, and be part of a community that thrives at the frontier of applied mathematics.
The Applied Mathematics Doctoral Seminar occurs every week during the semester. Dates, times, and locations are listed below.
