Biography

Dr. Abdallah Ramini was born in Amman, Jordan. He received his Bachelor (2004) and Master’s (2007) degrees from Jordan University of Science and Technology in Mechatronics Engineering. In 2012, He was awarded his Ph.D. degree in Mechanical Engineering from Binghamton State University of New York with a focus on the static and dynamic behaviors of MEMS devices and structures under shock. From 2012 to 2013, he was with Binghamton State University of New York as a Post-Doctoral Fellow working on the dynamical integrity of MEMS resonators. In 2013, he joined MEMS and NEMS Characterization and Motion Laboratory in King Abdullah University of Science and Technology, Saudi Arabia as Post-Doctoral Fellow. His research focuses on designing, modeling and experimentally characterizing microstructures with a focus on their mechanical and motion aspects under linear and nonlinear behaviors. Also, it focuses on the possibility to delve into the nonlinear dynamics of micro-oscillators and to more aggressively exploit nonlinear interactions. Dr. Ramini is a member of the American Society of Mechanical Engineers ASME.

Research Interests

Designing, modeling and experimentally characterizing microstructures with a focus on their mechanical and motion aspects under linear and nonlinear behaviors

The possibility to delve into the nonlinear dynamics of micro and nano-oscillators and to more aggressively exploit nonlinear interactions

To achieve a synergetic impact on essential problems in science and engineering by applying micro/nano-technology to nonlinear dynamics and vice versa

To study complex nonlinear behaviors, employ micro/nanoscale structures particularly those not routinely observed at the macro scale. Then, harnessed intentional nonlinearity in small size to implement model shifting designs for various applications based on the detailed understanding of nonlinear characteristics

Developed nonlinear micro-resonators by utilizing their intrinsically nonlinear characteristics for sensing applications such as broadband resonance, frequency tunability, and instability. Also, I published in Scientific Reports, Nature and Micro and Nanoengineering, Nature
