Research:
My research focuses on a dual barcoding approach to observe T-cell activation and correlate the activation profile with fluorescent and DNA barcodes using a droplet microfluidic approach. The fluorescent barcodes can then be used to enrich highly active cell pairs by droplet sorting, while the DNA barcodes allow annotation of the T-cell sequence with the observed T-cell's activation. I am also interested in imaging and characterizing heart-derived extracellular vesicles.

Research:
My main research focuses on developing novel models and treatments to improve liver preservation for transplant. By utilizing tissue engineering and molecular biology techniques, I develop benchtop models to better understand the role of various parameters on liver health and functionality. We hope that this knowledge will lead to an increased use of marginal livers in transplant scenarios thus expanding the donor pool and patient access to liver transplant.

Research:
Using a micro-spotting machine, I am examining the behaviors of immune cells during interactions with microbes, particularly the “neutrophil swarming” behavior. The role of neutrophil swarming during injury and infection in humans is poorly understood. Through our investigations we hope to both gain insight into the importance of swarming in humans and to apply this knowledge to develop ways to assist patients who may have swarming defects.

Research:
My research at the CEMS primarily focuses on developing liquid biopsy assay for analyzing circulating biomarkers of injury and rejection in solid organ transplants. I also develop non-invasive technologies for analyzing the quality of liver grafts for liver transplants. These technologies are used for analyzing health of the organ before the transplant when it may be machine perfused, or for analyzing health of the graft after transplantation in a patient.

Research:
I am interested in the design, fabrication, and applications of microengineered devices. I utilize these devices to study the mechanics of living systems, by exploring the relationship between diseases and their emergent mechanical properties in single cells and tissues.

My current research involves developing acoustofluidic methods to measure the stiffness of spheroids during nonalcoholic fatty liver disease (NAFLD) progression. I employ micro/nanofabrication methods to build high-precision platforms that can continuously analyze the disease stages at high throughput.

Research:
My research focuses on the development of a ‘skin-on-a-chip’ device to study the neutrophil behavior in the skin. Using the controllability of microfluidic devices, this study will provide the fundamental knowledge of how neutrophil function in skin disease, such as cellulitis. Eventually, I will apply my knowledge towards the development of rapid diagnostic tool for skin disease.

Research:
My research is focused in identifying molecular markers of progression in adult and pediatric solid tumors. We use circulating tumor cells and exosomes as models for blood-based biopsies to identify such markers, and better understand how tumors spread and metastasize. Using microfluidic technologies, we isolate tumor-specific exosomes and circulating tumor cells for downstream analysis such as single cell RNA sequencing, digital droplet PCR, label-free mass spectrometry and next generation sequencing.

Furthermore, I still try to integrate Anatomic Pathology into state-of-art technologies, such as microfluidic isolation of tumor-derived cargo, and to single-cell analysis of tumor content. Maintaining tissue architecture as part of analysis is a powerful way of understanding more than cell signaling pathways, but also to understand how those different tumor cells interact in space. To achieve this goal I apply multispectral imaging and multiplexed immunohistochemistry to validate single cell RNA-Seq results, providing important clues on how tumor architecture helps shape the multiclonal nature of tumor cells, and how they interact with the microenvironment.
