2004—2008, B.Sc., Physics (Solid State & Electronics), University of Tabriz, Tabriz, Iran 

Research Area(s): 
Research Interests: 
  • Computational Modeling in Biophysics,
  • Microswimers & bacterial predator-preys,
  • Single Molecule and Supper-Resolution Microscopy,
  • Microfluidics, Biophotonics, 
I'm doing research in Steve Presse’s group on biophysics. More specifically, I am working on chemotaxis, stochastic processes in microorganisms, and bacterial predator-preys. I perform computational modeling as well as experiments. Prior to my Ph.D., during my master's thesis project, I worked on fabricating electrically/optically switchable optical devices such as Fresnel lens and Bragg gratings, during which we proposed Michelson Interferometer as a new holographic technique to fabricate holographic Fresnel lens, and using that we build electrically and optically switchable Liquic Crystal Fresnel lenses. For more details see my publication in my CV and more info on the current projects could be found on our group's website: Projects

Honors, Fellowships, and Awards:

  • 2015-2017, IUPUI Graduate Student Imaging Research Fellowship (GSIRF) recipient, 
  • 2013-2014, Purdue Research Foundation (PRF) recipient for my Ph.D. thesis proposal,
  • 2008, Ranked 30th in the “National Entrance Exam for Graduate Programs” in the field of Photonics in Iran.
