About Me

Description of image
Hi! I am Juan Felipe Osorio Ramirez, a third-year PhD student 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.

My current research includes:

  • Learning/discovery of PDEs using GP/kernel methods with applications in planetary sciences and sismic data.

  • Solving Keller-Segle type equations using kernel methods.

During 2024-25 academic year, I will be the co-Lead Teaching Assistant for the Deparment of Mathematics at the University of Washington.
