Harsha Teja Garimella is a PhD candidate in Mechanical Engineering at Penn State. His research focuses on developing finite element models of the human head with axonal tractography to study traumatic brain injury. He has created high-resolution meshes and simulations of the head to analyze stresses experienced by axonal fibers under blast loading. Garimella has also developed electromechanical models of single axons and axonal bundles using COMSOL. He holds a BS in Mechanical Engineering from IIT Guwahati and expects to earn a PhD and MS from Penn State in August 2017.

CGPI - 8.71/10.00 Research Experience Ph.D. Candidate and Graduate Research Assistant August 2013 - present Department of Mechanical Engineering, The Pennsylvania State University. Ph.D. Thesis Project: Development of high-resolution embedded element based 鍖nite element model of the human head with axonal tractography. Advisor: Reuben H. Kraft, Ph.D. Created high-quality hexahedral meshes of the human head using MATLAB and ANSYS ICEMCFD. Developed explicit simulations of the high-resolution 鍖nite element model of the human head with axonal tractography, developed using the embedded element constraint in ABAQUS, to study brain injury. Developed the injury descriptions using the stress-strain response experienced by the axonal 鍖ber tracts. Developed blast (shock) loading simulations, in ABAQUS, of the human head model showing evidence of axonal injury due to skull 鍖exures (bending vibrations). Developing simulations to understand the e鍖ects of skulls natural frequencies on blast injury analysis. Other Projects: Electromagnetic modeling of the axonal 鍖ber bundles in human brain using COMSOL. Developed electromechanical model of single axon to study the changes in the electrical behaviour with mechanical strains using COMSOL and MATLAB. Currently developing electromagnetic models of single axon and axonal bundle. Modeling blast and ballistic penetration injury in lower extremity using Material Point Method. Developed innovative meshing tools, using MATLAB and C++, to create a high-resolution bio鍖delic model of the human leg containing complex anatomical components such as musculature Developed penetration simulations in Uintah to study the damage in di鍖erent anatomical regions. Design of robotic gripper by optimization of motor load torque variation. Collaborated with two team members and designed an optimal con鍖guration of gripper arm linkages by minimizing the load torque variation on the motor. We have developed a robust MATLAB code for this purpose and a computer aided design (CAD) model using SolidWorks. Implementation of an in-house MATLAB and C++ code to address the issue of volume redundancy - a limitation associated with embedded element technique in ABAQUS. Simulation of dual-battery systems in micro-hybrid vehicles using MATLAB/Simulink. Undergraduate Student August 2009 - May 2013 Department of Mechanical Engineering, Indian Institute of Technology Guwahati. Bachelor Thesis Project: Design and development of micro-hydraulic power generator. Advisors: P.S.Robi, Ph.D. and S.K.Dwivedy, Ph.D. Developed a CAD model of a new hydraulic power generator prototype, in SolidWorks, that utilizes the 鍖ow of energy of rivers to generate electricity with a novel concept of 鍖apper blades arranged over the rotating belt to generate electricity. Developed a 鍖nite element model of the 鍖apper blade to analyze the structural response of the blade under di鍖erent loading scenarios. Built the prototype using various model-shop instruments.
