This program has started since September 1999, in Institute for Advanced Studies in Basic Sciences (IASBS), for the first time in Iran. The students, which want to attend in this program, should be in the ¯rst thousand of students in the entrance exam of universities, which taking each year by ministry of science in Iran (total number of attendees are about 500,000).
This program consist of two major parts, in the first 4-5 years one should pass the courses, which cover BSc, MSc and PhD course. In the next 3 years one work on it's PhD thesis.

Between winter 2004 and 2005, with two of my friends and under the advice of Dr. Golestanian and Dr. Khalesifard, we studied the physical properties of porous and fractured glass using optical methods. We measured the porosity of these media using optical spectroscopy. We designed and fabricated a low-cost oven with an optical imaging apparatus to monitor the dynamics of the cracks visually. We discussed about the data and results with Prof. Swinney and Prof. Marder (Physics Dept. University of Texas, Austin) and Prof. Sahimi (Chair, Chemical Engineering Dept. USC). Refer to my proceedings.

In winter 2005 I joined to Optical tweezers group in (IASBS) for my PhD thesis. I choose Optical tweezers and their applications in biology, specially DNA properties, for my PhD research, and Dr. Golestanian is my supervisor. First we measured lateral efficiency of the trap, and investigated the effect of some optical parameters (to be appear in Optics Communication, Available online). Then we worked on efficient trapping in arbitrary depth by an oil immersion objective lens. By introducing new optical state we could have efficient trap in the arbitrary depth. It would be very useful for experiments, which the effects of surface aren't negligible. Before that people could only have efficient trap near the surface. It has been accepted by Optics Letter (refer to my publication).

From 2006 up to now, I am working on Thermal Diffusion Phenomena, trying to measure such a forces using Optical Tweezers. Here we try to find out the basic reasons which cause binary mixtures move under thermal gradient. It's a very complex phenomena because all gravitational forces, electrostatic forces, osmotic pressure and inertia moment are important.

From 2007 up to now I am collaborating with Miss Tavaddod and Dr. Golestanian and Dr Khalesifard in the movement of E-coli bacteria. Our goal is to compare diffusion and movement of different kind of E-coli. In more detail we genetically change the structural properties of E-coli and then look at changes in their movements. The most changes we done on E-coli are on their Flagella.
