PhD - Data assimilation in turbulent flows

Job description
We provide the opportunity for the joint Ph.D. program between UCSD and SDSU.

Research motivation
Do you know that measurement in a turbulent environment has its own "sixth
sense"? In fluid dynamical systems, measurements can be used to figure out
events that happened far away from the probing location.
Through state-of-art data assimilation techniques, we can trace back the origin
of any information we have measured. We used this technique to locate the
release of a pollution release, and reconstruct unknown flow fields from limited

Are you self-motivated to do a Ph.D. in interdisciplinary researches about fluid
dynamics, inverse problems, and optimization? We are looking for Ph.D. students
that are willing to spend time studying in an encouraging and creative

There has been a long-hovering question about how to combine experimental
measurements with numerical simulations. Especially in terms of designing a
turbulence model that agrees with experimental studies. In addition, the design
of sensor networks or sensor weighting can be optimized in terms of the amount
of information obtained.
In this Ph.D. project, you will develop novel simulation techniques that combine
machine learning techniques with data assimilation.

The required skills and preferred profile
0. We are looking for self-motivated young researchers from mechanical
engineering, aerospace engineering, computational physics, applied mathematics,
or other closely related areas.
1. Familiar with MATLAB and FORTRAN with MPI.
2. C++ and python is a plus.
3. Good conceptual understanding of calculus and linear algebra.
4. Experience with simple machine learning algorithms.
5. Good communication skills including presentation skills, academic writing
with latex or word.
6. Please note that the GRE is required for all JDP applicants and cannot be
7. Having a part-time hobby is a plus.

Work is carried out in the Data Assimilation group at Aerospace Engineering, San
Diego State University.
We study various inverse problems in fluid dynamics using numerical simulations
with the discrete adjoint operator.
