Yiran Wang

Welcome! I am an Assistant Professor at Department of Mathematics, Emory University. Before, I was a Postdoc Scholar at Stanford University working with Prof. András Vasy. I also worked with Prof. Gunther Uhlmann as an Acting Assistant Professor at University of Washington (with a joint position at IAS, HKUST). I obtained my Ph.D from Purdue University under the supervision of Prof. Antônio Sá Barreto.

My research interests are microlocal analysis, inverse problems, integral geometry, spectral and scattering theory.

In 2020 Fall semester, I will teach
  • Math 318: Complex Variables

  • Math 789: Topics in Analysis
In 2020 Spring semester, I am teaching Math 250: Foundations of Mathematics.

In 2019 Fall semester, I taught Math 112z: Calculus II.

In 2019 Winter quarter, I taught two courses at Stanford. In 2018 Autumn quarter, I taught Math 19: Calculus at Stanford.

In 2018 Summer and Spring quarter, I taught three courses at University of Washington.
