Educational Background
Virginia Tech: Ph.D. in Engineering Mechanics
Saadbin Khan’s academic career at Virginia Tech began in 2021 when he embarked on his Ph.D. in Engineering Mechanics. His area of research centers around computational mechanics, a branch of engineering that uses mathematical models and simulations to analyze physical phenomena. The research project he is currently working on, funded by the NSF, explores the role of hydrodynamic slip in insect respiration. This project stands at the intersection of fluid dynamics and biology, where Saadbin applies high-performance computing methods to study how fluid flow behaves in tiny, complex biological systems like the tracheal networks of insects.
Saadbin’s work at the Laboratory for Fluid Dynamics in Nature (FINLAB), under the guidance of Dr. Anne Staples, demonstrates his ability to merge advanced computational methods with biological insights. The research investigates how the physical properties of fluids, such as viscosity and flow rates, impact the efficiency of respiration in insects. This work is crucial for understanding biological systems and can have broader implications in bioengineering, including the design of artificial respiratory systems and the study of biological fluid dynamics.
Oklahoma State University: Master’s in Mechanical & Aerospace Engineering
Before joining Virginia Tech, Saadbin Khan earned his Master’s in Mechanical and Aerospace Engineering from Oklahoma State University. During his time at Oklahoma State University, Saadbin worked as a Graduate Research Assistant in the Computational & Flow Science Research (CFSR) Laboratory. Under the mentorship of Dr. Balaji Jayaraman, Saadbin contributed significantly to understanding the near-wall structure of wavy channel turbulence through Direct Numerical Simulations (DNS).
At the CFSR Laboratory, Saadbin also worked on a project in collaboration with Baker Hughes General Electric (BHGE), where he developed code for an improved plume source inversion model. This model was designed for efficient remote leak detection in atmospheric dispersion applications, a project critical for environmental monitoring and safety. His contributions involved coding and modifying subroutines using Fortran, along with developing post-processing and analysis tools using Python.
