I am a graduate student at Indiana University Purdue University Indianapolis (IUPUI) pursuing a masters in Mechanical Engineering. I completed my undergraduate studies at IUPUI and received a B.S. in Mechanical Engineering. For my graduate studies, my focus is in thermal/fluid sciences and systems/controls. Currently, the research I am involved with is in the area of electrical propulsion. Specifically, it is electrical propulsion by means of pure ionic emission. The objective of the research is to construct an experimental test chamber to test different propellants for the characterization of an optimal propulsive system. The optimal system is determined by the specific impulse and propellant flow rate. The one with the highest specific impulse and the lowest flow rate is the desired propulsive system. Although my primary focus is with this, I participate in many projects related to controls and heat transfer. Aside from my research, I focus heavily on the advancement of engineering education at the collegiate level. I work on revising and updating laboratory experiments to help improve student understanding of how concepts are applied and utilized. I also spend time writing design optimization MATLAB codes for various applications.

The convection heat transfer coefficient is explored for a new academic laboratory experiment. A cost-effective design is generated with three core principles: 1) Low Cost, 2) Low Maintenance, and 3) Concept Visualization. This is achieved through the following description of the apparatus. The plexiglass chamber has a square base with a designated height. At the bottom of the chamber, there is a rectangular section removed to act as an inlet to the chamber. A high powered mini turbine fan is located at the top of the chamber. The fan acts as the driving force that pulls in the surrounding air from the inlet to generate a flow within the chamber. A hatch is located on the side to allow for interchanging of different test geometries. The geometries being used are 3D printed to components either in the form of a fin (External Flow) or a hollowed channel parallel to the flow (Internal Flow). The components are mounted to the chamber wall with a heater in a plate in between. The component is heated until steady state, where the average temperature along the surface is calculated. The velocity, surface temperature, ambient temperature are recorded through the use of a data acquisition system. The resulting convection coefficients are then determined.
