Zahra Keyshams

As a postdoctoral researcher, I am currently working remotely in the Ghent Analysis and PDE Center at Yerevan State University, with a focus on Partial Differential Equations (PDE). Before this, I spent several years in Isfahan studying and teaching mathematics.

 I have a keen focus on Harmonic Analysis, having completed my doctorate at the University of Isfahan with research titled “Frame, Wavelet, Gabor System Theory, and Applications”.

Research Interests:

  • Hilbert Spaces
  • Banach Spaces
  • Ordinary and Generalized Frames
  • Tensor Product Frames
  • Fourier Analysis
  • PDEs

Education:

I obtained a Ph.D. in Harmonic Analysis in 2021 from the University of Isfahan, Iran with a thesis titled “Frame, Wavelet, Gabor System Theory, and Applications” under the guidance of Dr. Fatemeh Abtahi, scored 19.40 out of 20.
