Teaching Experience
At Purdue University, I assisted Prof. Rodney Trice in teaching Fundamentals of Materials Engineering (MSE 230) in the Summer of 2021. I hosted office hours, helped students understand the basic concepts of materials, administered weekly quizzes and, helped the professor in grading midterms and final exams.
At the University of Toledo, during my MS, I worked as Graduate Teaching Assistant and assisted Prof. Dr. Anju Gupta in teaching the lab class, Measurement Lab (MIME 2000). I worked as lead TA and coordinated the assignments of other TAs, developed the lab instructions, and demonstrated the sensor calibration experiments to the students.
Research Experience
Graduate Research Assistant, Trice Ceramics Lab & Martinez Soft Materials Lab,
Purdue University, West Lafayette, Indiana (September’20-December’23)
Ph.D. Dissertation: Design and Evaluation of Rare-Earth Oxide Co-Stabilized Cubic Zirconia for Hypersonic Flight (Funded by Office of Naval Research, US Government)
I have been developing a high-emissivity, high-temperature ceramic coating material that can protect the underlying hypersonic structural objects from oxidation and ablation-induced damage. Toward that objective, I have designed industry-scalable rare earth oxide (REO) modified refractory material that can successfully protect the hypersonic C/C structures by reducing ablation-induced mass loss by 70%.
Graduate Assistant, Multifunctional Material Lab,
The University of Toledo, Toledo, Ohio (September’18-May’20)
MS Thesis: Ageing Resistant Toughened Zirconia as a Dental Implant Material
I received my training as a materials scientist. I implemented that training to find an alternative age-resistant ceramic material for dental implants exhibiting similar mechanical properties and lattice structure before and after exposure to a humid oral atmosphere.
