About Me

Description of image
Hi, thanks for stopping by! I am Juan Felipe Osorio Ramirez, a fourth-year PhD candidate in Applied Mathematics at the University of Washington, where I study the mathematics of data science and its role in solving and learning PDEs, particularly in physics-informed modeling and the emerging field of scientific machine learning using kernel methods. I am fortunate to work under the supervision of Prof. Bamdad Hosseini.

News

  • Open to Summer 2026 Internship Opportunities in ML/AI, Data Science, or Quantitative research.

  • I will be giving a talk at SIAM-PNW 2025 (Seattle,US) on using kernel methods for learning and emulating PDEs.

  • I will be giving a talk at SIAM-PDE 2025 (Pittsburgh,US) on characterizing Jupiter’s radiation belt through PDEs using SciML kernel methods.

Current research projects

  • Learning stochastic PDEs in finance using kernel methods.

  • Learning/discovery of PDEs using GP/kernel methods with applications in planetary sciences (Jupiter’s radiation belt) and sismic data.

  • Scalability of kernel methods for learning systems of PDEs using distributed methods in optimization.

  • Solving time-dependent PDEs using kernel methods including Fokker-Planck and Keller-Segle models.
