4. Robotic Foram Imaging System (ECE ME)
Work as Mechanical Engineering consultant, providing advices for the assembly, material
selection, and presentation.
Project use a robotic arm system combined with a vacuum suction device to select and
categorize Foram fossil with diameter less than 1mm.

7. Undergraduate Researcher (Tunnel Lab)
Work with graduate students, conducting experiment for the heat dissipation under the
condition of jet impingement.
Project use a sealed wind tunnel create jet impingement and use thermal sensors to record
different experiment data, which will be further analyzed.
Procedure:
Assemble the
equipment and start
experiment
Record and analyze data,
while discover issues
with experiment
Redo the
experiment and
report drafting
Provide improved CAD
model for the next phase
of the experiment

11. Internship Experience (Impro China Limited)
Work as an Intern Mechanical Engineer with senior R&D engineering. Mainly focus on the
designing and quality checking at each stage of the product production.
During the internship, the position require working in a cross-function team, and exchange ideas
with different department to solve the problem.
Impro precision is a Company focus mostly on casting and precision machining. Most of my work
involve company core technologies, therefore the disclosable information was limited.
