Graduate Teaching Assistant
Job overview
- Utilized advanced skills in 3D modeling to design the system with simulating multiple perspectives: functionality, practicality, ease of construction and cost-effectiveness
- Decompose the designed system into pieces, collaborate with machine shop and commercial vendor to fabricate each piece, and assemble the pieces to form the entire system in the lab
- Design, development and assembling of an alpha irradiation system featuring cost-effective alpha source, high vacuum, and focusing lens-based beam delivery
Job overview
- Performed computer modeling to successfully optimize the de-magnification factor by 10X enhancement in focusing strength compared to microbeams of similar size, type, and voltage attenuation
- Simulated the anti-aberration strategies to improve the robustness of the optimized focusing lens system in maintaining the focusing strength
- Devised and optimized a novel electrostatic focusing lens system for optimal beam focusing effects on ion beam delivery
Job overview
- Overseeing and coordinating the transfer of lab equipment for surplus, donation, disposal, and other necessary actions
- Overseeing both radiation and chemical safety regulation practices
- Site specific training for all hazardous and dangerous materials to all new members joining the lab
- Monthly radioactive contamination and safety checks
- Overseeing the purchase, usage, and maintenance of multiple lab devices
