Amir H. Behbahani

I received the B.S. degree in Mechanical Engineering from the Sharif University of Technology, Tehran, Iran, in 2013, and the M.S. and Ph.D. degrees in Mechanical Engineering from the University of California at Los Angeles (UCLA), Los Angeles, USA, in 2015 and 2018, respectively.

I am currently a Postdoctoral Scholar at Michael Dickinson Lab at the division of Biology and Biological Engineering (BBE) at California Institute of Technology (Caltech), Pasadena, USA.

Research

I am currently interested in

  • Modeling and analysis of Drosophila melanogaster (fruit fly) wing rotation
  • Studying the role of various neurons on the fruit fly dynamical behavior related to flight
  • Conducting experiments on various fruit flies genotypes to understand their walking behavior

 

As a Ph.D. student at UCLA,  I worked on

  • Development of a wafer-level post-fabrication modification technique
  • Systematic manipulation of multiple pairs of modes of MEMS resonators
  • Design, analysis, and modeling of MEM ring resonators
  • Development of a new approach for modal parameter estimation • Modeling (analytical and finite element) of ring dynamics
  • Studying of damping mechanisms in ring type resonators
