Research Program

Cancer Biology, Extracellular Vesicles & Translational Therapeutics

Our program moves from the molecular biology of tumor cells and their microenvironment to engineered delivery platforms designed for clinical translation — organized here into seven interconnected research areas.

01 · Research Area

Extracellular Vesicles and Exosome Engineering

Exosomes are nanoscale, cell-derived vesicles that naturally shuttle proteins, lipids, and nucleic acids between cells. We engineer them into targeted, low-immunogenicity delivery vehicles for cancer therapeutics.

Biological Significance

Exosomes offer a biocompatible alternative to synthetic nanoparticles, but clinical use is limited by poor tumor selectivity and rapid clearance by the liver and spleen.

Key Questions

Which surface modifications best balance tumor-selective uptake against immune clearance? How does cargo-loading strategy affect delivery efficiency?

Experimental Approaches

CD9/CD63 surface engineering, dual-ligand display (e.g., RGD targeting with CD47 immune evasion), in vitro uptake assays, and in vivo biodistribution imaging.

02 · Research Area

Endosomal Escape and Intracellular Delivery

Most vesicles that reach a target cell remain trapped in endosomes and are degraded before their cargo can act. We study how to route more of that cargo into the cytoplasm.

Biological Significance

Endosomal entrapment is one of the principal bottlenecks limiting the therapeutic efficacy of nucleic-acid- and protein-based cargo delivered by extracellular vesicles.

Key Questions

Which fusogenic or pH-responsive modifications most efficiently trigger membrane disruption and cargo release? How is escape efficiency best quantified?

Experimental Approaches

HiBiT/NanoLuc split-luciferase reporter assays, live-cell confocal imaging of endosomal markers, and structure–function screening of fusogenic peptides.

03 · Research Area

LAMC2–Integrin Signaling in Cancer

LAMC2, a subunit of laminin-332, is upregulated at the invasive front of several carcinomas and signals through integrin receptors to promote invasion.

Biological Significance

Understanding how LAMC2–integrin engagement drives invasive signaling in pancreatic and lung cancer may reveal new anti-invasive therapeutic targets.

Key Questions

Which integrin partners mediate LAMC2 signaling in our tumor models, and can this interaction be disrupted without harming normal epithelium?

Experimental Approaches

CRISPR-based perturbation, 3D organoid invasion assays, and pathway-level signaling analysis in patient-derived models.

04 · Research Area

KRAS-Driven Tumor Biology and Therapeutics

Oncogenic KRAS mutations drive the majority of pancreatic cancers and a substantial share of lung cancers. We study KRAS-dependent signaling and how to target it selectively.

Biological Significance

Despite recent pharmacological advances, selectively delivering KRAS-directed agents to tumor cells while sparing normal tissue remains a major translational challenge.

Key Questions

Can engineered exosome platforms improve selective delivery of KRAS-pathway-directed payloads to mutant tumor cells?

Experimental Approaches

RNA interference and gene-silencing payloads, KRAS-mutant cell line and organoid panels, and pathway-activity reporter assays.

05 · Research Area

Pancreatic Cancer and the Tumor Microenvironment

Pancreatic ductal adenocarcinoma (PDAC) is defined by a dense, immunosuppressive stroma that limits drug penetration. We model this microenvironment to understand resistance and identify vulnerabilities.

Biological Significance

Stromal and immune components of the PDAC microenvironment shape both tumor progression and the efficacy of systemically delivered therapeutics, including extracellular vesicles.

Key Questions

What mechanisms of apoptotic dormancy and drug resistance operate within the PDAC microenvironment, and how can they be reversed?

Experimental Approaches

Orthotopic and patient-derived xenograft models, stromal/immune co-culture systems, and mitochondrial apoptotic-pathway analysis.

06 · Research Area

Tumor Targeting and Drug Delivery

Improving the fraction of a systemically administered therapeutic dose that reaches tumor tissue is central to nearly every project in the lab.

Biological Significance

Rapid clearance by the mononuclear phagocyte system and poor tumor selectivity limit the efficacy of many nanocarrier-based cancer therapeutics.

Key Questions

Which combinations of targeting ligands and immune-evasion signals most improve tumor accumulation and circulation time in vivo?

Experimental Approaches

In vivo fluorescence and bioluminescence imaging, pharmacokinetic and biodistribution analysis, and CD47/SIRPα immune-evasion engineering.

07 · Research Area

Molecular and Translational Cancer Therapeutics

We aim to move mechanistic findings toward therapeutic strategies that could ultimately be evaluated in the clinic.

Biological Significance

Bridging laboratory discovery and clinical application requires therapeutic platforms that are both mechanistically sound and pharmacologically deliverable.

Key Questions

How can engineered EV delivery platforms and pathway-targeted agents be combined into rational, translatable combination therapies?

Experimental Approaches

Preclinical efficacy studies in xenograft and orthotopic models, combination-therapy screening, and pharmacokinetic/toxicity assessment.
