Project Title: Cancer cell–intrinsic inflammatory programming drives leptomeningeal metastatic adaptation
Leptomeningeal metastasis (LM) is a devastating complication of cancer in which tumor cells spread into the cerebrospinal fluid, a nutrient-poor environment that becomes increasingly inflammatory as the disease progresses. This study investigates how LM cancer cells adapt their internal signaling to survive in this challenging environment and spread throughout the central nervous system. By uncovering these adaptive mechanisms, this work aims to identify new therapeutic vulnerabilities that could lead to more effective treatments for patients with LM.

Project Title: Decoding the role of peripheral nerves and perineural invasion in pancreatic cancer metastases
Pancreatic ductal adenocarcinoma (PDAC) is an aggressive cancer often diagnosed after it has already spread, with a unique tendency to grow around and invade peripheral nerves—a process known as perineural invasion (PNI) and associated with poor prognosis. This study investigates the features of a distinct perineural niche within the pancreatic tumor microenvironment, characterizing nerve-educated cancer and stromal cells that promote tumor progression and spread to distant organs using nerves as a conduit. Through advanced cellular and spatial profiling of human pancreatic tumors, mouse models, and coculture systems with peripheral nerve ganglia, this research aims to uncover mechanisms by which nerve–tumor interactions promote metastasis and identify novel therapeutic targets by modulating nerve activity.

Project Title: Healing the Wound: Targeting cancer-like niches in the premalignant pancreas for tumor interception
Pancreatic ductal adenocarcinoma (PDAC) is an aggressive cancer, with over 80% of patients presenting with invasive disease. Metaplastic cells disseminate early in PDAC development; however, means to identify and target aggressive cell states at early stages are lacking. Using single-cell and spatial analyses in PDAC mouse models, we previously found that a unique population of highly plastic and invasive premalignant cells exist within a fibrotic, inflammatory niche that upregulates wound healing pathways and mirrors the PDAC tumor microenvironment. These cancer-like niches are tightly interconnected, such that natural tumor suppression by p53 not only targets the invasive cells but dismantles the entire niche. Thus, these niches are prime targets for cancer prevention efforts. This study seeks to uncover the consequences of disrupting these multicellular ecosystems on PDAC initiation using genetic, pharmacological, and cell therapy-based approaches in PDAC mouse models and organoid co-cultures. This work will provide novel insight into the multicellular mechanisms that drive malignant transformation, ultimately informing future efforts towards cancer interception.

Project Title: Glycosphingolipid-Driven Immune Evasion as a Targetable Vulnerability in Metastatic Clear Cell Renal Cell Carcinoma
Clear cell renal cell carcinoma (ccRCC) undergoes VHL-driven metabolic reprogramming and features dramatic accumulation of lipids, yet how these lipids change over the course of disease and support progression to a more immune-resistant, metastatic stage remains poorly understood. Glycosphingolipids, a class of surface lipids, are elevated in metastatic ccRCC compared to less aggressive disease in an immune-dependent manner, raising the question of their functional role in tumor progression. This project will use high-resolution lipidomic profiling, combined with preclinical metastasis models and genetic approaches, to systematically define how glycosphingolipids regulate the tumor microenvironment and support immune evasion during ccRCC metastasis. Through this integrated lipidomic and in vivo approach, this work aims to define the role of these lipids in malignant ccRCC and to develop novel strategies for improving immunotherapy response in patients.

Project Title: Drivers of stromal and epithelial transitions in ovarian cancer peritoneal metastasis
High-grade serous ovarian cancer (HGSOC) exhibits a distinctive pattern of metastasis in which cancer cells shed directly into the peritoneal cavity, form heterotypic spheroids with cancer-associated fibroblasts (CAFs), and ultimately implant at distant peritoneal sites. This process requires two critical phenotypic transitions: the progression of fallopian cells from benign p53-mutant precursors to a state capable of anchorage-independent growth, and the emergence of specialized fibroblast states that support cancer cell survival in suspension. Despite their clinical importance, the genetic drivers of these transitions remain poorly understood. This project aims to synthetically recapitulate and thereby mechanistically understand these transitions using a combination of novel genetics techniques and Perturb-seq, a single-cell screening technique that can link engineered genetic changes to their phenotypic impacts at scale.

Project Title: Breaking the Vicious Cycle: Visualizing and perturbing cancer-osteolineage cell interactions to better understand bone metastasis.
Skeletal metastasis is one of the most devastating complications of cancer, causing intense pain, bone weakening, and high mortality. In the bone, osteoblasts (which deposit bone material) and osteoclasts (which resorb it) regulate one another in a coordinated cycle of resorption and deposition. Cancer cells hijack this cycle, hyperactivating osteoclasts and using the resulting secreted cues to stimulate further bone degradation and tumor expansion. This project aims to better understand how cancer cells inject themselves into this cycle and abuse it.

Project Title: Uncovering the regulatory mechanisms leading to leptomeningeal metastasis through multimodal single-cell sequencing across time and space
Systemic cancer spread to the central nervous system (CNS) - leptomeningeal metastasis (LM) - is a devastating diagnosis, entailing disproportionate morbidity and short survival. The limited existing treatment options are merely palliative since cancer invasion into the CNS entails irreparable damage, while the incidence of LM increases with improved treatment options that prolong patient survival, but the mechanisms leading to LM are unknown. The leptomeninges differ from the parenchyma of other metastatic sites as their tissues and fluids are unique in the body; the cerebrospinal fluid (CSF) is a nutrient-depleted environment that has - under normal conditions - traditionally been perceived as isolated from the rest of the body through epithelial cells in the choroid plexus (CP) that form the blood-CSF barrier and produce CSF. Yet, during LM, the epithelial barrier loosens to allow passage of molecules and cells from the CP stroma into the CSF as they pass fibroblasts. Our current understanding of disease progression leads me to a provocative hypothesis that we will study using custom-developed mouse models, high-resolution and multimodal spatial sequencing technologies, and novel computational tools: CNS fibroblast actively remodel their niche in anticipation of LM to recruit, select, and ultimately help administer cancer cells into the CNS.

Project: Mitochondrial DNA Mutations as Key Drivers of Renal Cell Carcinoma and Modulators of Anti-Tumor Immune Response.
Truncating somatic mutations involving protein-coding genes in mitochondrial DNA (mtDNA) occur in 10% of all cancers, and in up to 20-30% of kidney cancers (Gorelick et al., 2021). The 13 protein-coding genes of the mitochondrial genome encode for key components of the electron transport chain (ETC). Homoplasmic germline mtDNA mutations involving the ETC genes profoundly disrupt mitochondrial oxidative phosphorylation and are universally lethal. Heteroplasmic germline mtDNA mutations lead to mitochondrial disease phenotypes in cells dependent on efficient ATP production, with a significant proportion of patients having renal dysfunction (Gorman et al., 2016; Govers et al., 2021). Paradoxically, somatic mtDNA mutations in cancer involving these genes appear to be under positive selection, despite disrupting the key pathway of ATP generation (Gorelick et al., 2021; Kim et al., 2022). mtDNA research in cancer has been hampered by the limited availability of dedicated mtDNA sequencing and the lack of tools to experimentally model mtDNA variants. Crucially, while mtDNA mutations have been extensively studied in the context of inherited diseases, their role in cancer remains largely unexplored.
We will leverage novel computational advances in mtDNA mutation calling and new methods of mtDNA engineering to study the effect of these somatic mutations on metabolic rewiring, the development of selective dependencies, and the modulation of immune checkpoint inhibitor (ICI) response. Renal cell carcinoma (RCC) represents the ideal tumor to study mtDNA mutations given the high frequency of mtDNA mutations, extensive metabolic disruptions, and responsiveness to ICI. Our overarching hypothesis is that mtDNA mutations cooperate with hypoxia to rewire tumors to a Warburg-like phenotype, which in turn reshapes the immune microenvironment of tumors and can be leveraged to induce synthetic lethalities by inhibiting glycolysis, inducing ferroptosis, or exposure to hyperoxia.
