Biography

Dr. Sanei is an assistant professor in Mechanical Engineering Department. Dr. Sanei joined Penn State in August 2016. He received his Ph.D. from the University of Wyoming in 2016. 

 

Teaching

Dr. Sanei has pedagogical experience ranging from lab instruction, guest lecturing, and principal instructor at three different universities.

Teaching Philosophy

One of the main challenges in undergraduate teaching is to motivate students to appreciate the importance of topics covered. This could be achieved by providing students with real life engineering examples. Each course is different and therefore the teaching strategy should be unique to each course. For instance, while an intermediate mechanics of materials class may require weekly homework as adequate practice, advanced classes such as finite element analysis or composite materials require larger computer projects using ABAQUS and MATLAB in order to put into practice the concepts studied. PowerPoint presentation might be perfect for image analysis class, but it is a poor strategy for teaching Mechanical Vibrations.  A major challenge in teaching complex concepts is to keep in sight the larger application without being distracted by the details. Therefore, stating the problem and providing the big picture is as important as demonstrating an understanding of the details. While most of undergraduate teaching strategies apply to graduate instruction, teaching at graduate level should focus on equipping students with critical thinking skill by prompting them to read and dissect research papers. I give them the liberty of selecting papers in line with their thesis or dissertation research.  

I believe strong teacher-student rapport is a crucial element of enhanced learning. As a teacher one should build relationships by fostering a feeling of community and personally interacting with each student. Every question should be welcomed and every attempt at answering one must be encouraged. The teacher-student relationship should not end after final examination. A teacher should build an attitude that students feel comfortable seeking advice from their professor beyond classroom experience.  Teaching, like other skills, can and should be continually improved through student and peer feedback. Instructors must have the ability to incorporate different perspectives into their teaching style.

Research

Dr. Sanei’s research interests are in the area of

  • Composite Materials: Computational Modeling, Manufacturing and Experimental Testing                   
  • FEA: Nonlinear FEA, Stochastic FEA and XFEM
  • Material Characterization: Nanoindentation, Micrograph Analysis
  • Multiscale Modeling: Homogenization technique, RVE, SVE and UVE Modeling   
  • Failure and Fracture Mechanics
  • Image Processing: Image acquisition with SEM, TEM and Optical microscopy, Image analysis of micrographs

Composite materials are widely used in different application simply because they are offering properties that other materials cannot. Despite the advantages associated with the use of composite materials in different industrial sectors, variability in their properties has made predicting their reliability a challenge and led to the use of high safety factors in real applications. While such variability has been studied experimentally, the link between the observed variability and the physics of the underlying microstructure has not been rigorously established. Such variabilities are present in microstructures in the form of both morphological and constituent properties variability. It is important to determining such variabilities and incorporate them in stochastic modeling to predict the macroscopic properties.
