With over 10 years’ experience as a professional engineer, I have worked on the design, development, and manufacturing of prototypes and commercial products and am excited to collaborate with clients to find solutions to their engineering needs. No matter what stage of the product development lifecycle I am working on, I strive to complete all projects on time and at the highest level possible as my top priority is to achieve 100% satisfaction with every project I complete. I put a large emphasis on clear and constant communication and am always available to call or zoom to discuss project specifications, objectives, feedback, or new directions. The services I can help with include: - Computer-Aided Design (CAD) - Computer-Aided Engineering (CAE) - Computer-Aided Manufacturing (CAM) - 3D Solid Modeling - 3D Surface Modeling - 2D Engineering Drawings - Mechanical Design - Product Rendering - Design for 3D Printing - Design for CNC Machining - Design for Injection Molding - Design for Sheet Metal Fabrication I can also 3D print your product in a variety of materials (TPU, PLA, ASA, and PETG) for evaluation and design review (256 x 256 x 256 mm) if needed. Example CAD designs of previous projects can be delivered upon request or can be found on my company website here: brainbotlabs.com. More about me: I graduated with my bachelor’s degree in biomedical engineering and have gone on to receive two master’s degree in biotechnology and education along with two graduate certificates in applied biostatistics and college teaching. I am also the co-inventor of multiple patents and an author of several peer-reviewed publications where I presented my work at both regional and national conferences. Additionally, I spent the last few years developing an engineering program for high school students to help develop the next generation of scientists and engineers.

I am a computational physicist (PhD and postdoc in computational photonics) with extensive experience of solving physical/mathematical problems in both academia and industry. The following provides a summary of the work I have done: 1) Computational simulations of physical systems. This involved electromagnetics, electro and magnetostatics, current flow in ionic cells (dc and ac), diffusion, structural mechanics and charged particle tracing. 2) Optical system design and analysis. I specialize in optics so this topic has been a recurring part of my work. Particular examples include Fourier optics, gaussian beam propagation and aberration analysis. 3) Machine learning, mathematical optimization and signal processing. Physical problems in products naturally overlap with concepts in mathematical modelling. I have used signal processing, machine learning and nonlinear optimization and filtering methods for both 1D and 2D data. 4) I began my journey as an electrical engineer. I am familiar with electrical systems and have hands on experience of programming microcontrollers and FPGAs. As for tools, I am an advanced user of Comsol Multiphysics and opensource FEM code FeniCS. For scientific programming, I have extensively used Matlab, Python and Julia.
