Research Interests

The primary focus of my work is investigating how nano and sub-micron sized particles influence cellular immune responses, with a particular interest in how particle-immune cell interactions may ultimately influence adaptive T cell immunity. The rationale for these studies is that by understanding the immune-modulatory properties of particles, these properties can then be harnessed for therapeutic effect. Conventional and imaging flow cytometry are key techniques employed in my area of study, and I am especially passionate about the utilization of imaging flow cytometry techniques for quantitative deep profiling of cells and internal cellular processes, to advance our understanding of cellular mechanisms in heath and disease, and for the development of novel therapeutics.
