•From January 2008 until now -->

Research Assistant (PhD Student) at Binghamton University - State University of New-York (Binghamton University WebPage)

I'm pursuing my PhD in the Mechanical Engineering Dapartment ( Please click here to consult The BU Mechanical Engineering Department Web Page) at Binghamton University for several reasons:

- I'm expanding my knowledge in the area of Micro-Electro-Mechanical Systems, MEMS, specially in the field of microfabrication because I have acquired some fundamental background of this area during the BS and MS programs at Ecole Polytechnique de Tunisie, Tunisia and I would like to expand it more;

- Binghamton University with its comprehensive facilities (Innovative Technologies Complex) and competent faculty members in the field of microtechnology would be an ideal place for me to pursue graduate studies and will offer me the chance to cope with the latest research developments in this field;

- I'm expanding further my knowledge in microtechnology and build a stronger research basis with the assistance of experts in this field. For this, I'm under the supervision of an imminent professor in this field, Pr. Mohammad I Younis (Binghamton University, USA) Pr. Mohammad Younis Webpage.

- I and Pr. Younis are doing some staff on the reliability of microstructure and try to model some instabilities that may cause failure of some microdevices under the effect of electrostatic, capillary and shock forces. We are also tacling the problem of Arch beam under the effect of electrostatic force. Some modeling of carbon nanotube "CNT" resonator are also been done by exploring the possibility to built nano mass sensor based on CNT.

- I obtained on March 18th, 2008 a certificate of appreciation in the Graduate Student Research Day that had been held on Binghamton University. (See photo on GSRD photos.)
