Now that I'm a research assistant at graduate school in mechanical engineering, I'm having trouble finding precisely where my research interests lie. At least part of my problems stem from the fact that my undergraduate degree is in physics, not engineering. Here are the math/physics/engineering-related courses I took as an undergrad: University Physics I & II Modern Physics I & II Statics Engineering Circuits Digital Circuits Engineering Thermodynamics Classical Mechanics Quantum Mechanics Classical Physics Laboratory Calculus II and III Ordinary Differential Equations Linear Algebra Proof Techniques Abstract Algebra Applied Statistics Mathematical Statistics I & II Probability The graduate courses I'm currently enrolled in are: Aerodynamics Modeling and Simulation of Mechatronic Systems Manufacturing Techniques With this background, what mechanical engineering research area am I best suited for? I still have a month or so to find a niche, but I would appreciate any advice or input regarding this situation. Does anyone have a suggestion for a particular research endeavor I have the tools/skills to successfully do work on? Thanks in advance!
