For my thesis, I worked with Dr Y.Y. Tsui as part of his Optics & Photonics lab. My thesis work involved creating a label-free microfluidic cytometer to distinguish and sort rare biological cells. A conventional cytometer requires cells to be "labelled" with florescent tags, which is costly and time consuming. The label-free technique eliminates this step by using 2D Mie scatter patterns from a laser impacting off a single cell. This scatter pattern distinguishes the cell and it can then be sorted with a microfluidic flow control system.Throughout the process, I setup and worked in a biosaftey lvl 2 lab, used nanofabrication processes (lithography, wet etch, RIE, etc.) in a fabrication cleanroom, interfaced optical sensors with LabVIEW, processed digital images, and more.I was also involved in the research for a potable hydrocarbon sensor for environmental applications (i.e. oil sands tailings)Publications & Conference Presentations:[Poster, awarded best conference poster] Debbie Ha, M.
