Overview of research

Recent Times Colonist newspaper article:
It has been a privilege to be able to collaborate with many outstanding researchers. As I said in the article, it is not about competition among us but how we can achieve big targets together. I try to combine teaching and research together to motivate our next generation. It has been very successful so far. I never underestimate potential of students. They just need good guidance to build that passion within them selves to navigate roadblocks. I use my story as a tool.
I hope you will enjoy this article.

My recent interview with the faculty: 
It aims at communicating research to a broader community around the world. I talked about use of smart nanomedicine in the treatment of cancer. This is just over 10 minute video. I am very grateful for all the researchers in the field who had contributed immensely and also the ones who are working really hard to make this nanomedicine accessible to more cancer patients in the near future. I did my PhD in Quantum physics and the opportunity to be able to contribute to cancer research is very rewarding. 

The talk I gave as part of the Dean's lecture series at the 番茄社区:
I talked about the endless opportunities of nanotechnology in cancer research. I hope you will enjoy. Our dean, prof. Peter Loock, gave a very kind introduction before my talk. I incorporate my research into teaching as well. To be able to mentor our young generation via both teaching and research is a blessing. I enjoy every minute of it.

Cancer Nanotechnology & Medical Physics

Research Projects

Nanotechnology involves creation and utilization of materials, devices or systems on the nanometer scale. The field of nanotechnology is currently undergoing explosive development on many fronts. Among other fields, nanotechnology is expected to generate innovations and play a critical role in the field of cancer nanomedicine.

My research program also involves the use of gold nanostructures as a versatile platform for integration of many therapeutic options towards optimizing combinational therapy platform in the battle against cancer. For example, radiation therapy and chemotherapy remain as the most widely used treatment options. Our studies show that the incorporation of gold nanostructures into those protocols have enhanced tumor cell damage. However, nanoparticle based platforms are still at the initial stage of development and much more research is required before they can be applied in clinical applications.

Therefore, this emerging field of nanomedicine requires better understanding of the interface between nanotechnology and medicine in order make use of their full potential in the clinic. My research program is designed to improve the understanding of the bio-nano interface. Better knowledge of the nano-bio interface would lead to better tools for diagnostic imaging and therapy. As a step forward in this direction, we have shown how the size, shape, and surface properties of nanoparticles (NPs) affect their intracellular fate both in vitro and in vivo. We also engineer three dimensional tissue-like models to test our nanoparticle systems before using then in animal models. These fundamental studies will facilitate building of better NP-based platforms for improved results in the future cancer care of patients.

 

Teaching

2023-2024 Academic year:

PHYS120: This is an introductory physics course.

PHYS232: This course delivers materials related to special topics in biomedical sciences. In other words, we will learn to use the physics we learned in the first year to understand their applications in biomedical sciences. This includes biomedical imaging, therapy, and diagnostics. We will also tour the British Columbia Cancer Agency to witness how some of the things you lean in the course is used in day today.
