Research we fund

I aim to identify drivers of pediatric and adolescent/young adult lymphoma disparities so that targeted health equity interventions can be developed. Integration of large datasets, systematic collection of social determinants data in clinical trials, and collaboration with patient advocates will: a) create new population-based resources to study lymphoma outcomes; b) establish a novel framework for equity research in lymphoma clinical trials; and c) identify real-world targets for intervention.

The genomic architecture of residual CLL and molecular determinants of disease progression after targeted combination therapy are unknown. In a phase 2 study of zanubrutinib and venetoclax in CLL, I will investigate the depth of response and genomic changes using cellular and circulating tumor DNA. Data generated from this proposal will provide foundational evidence to develop genomic markers for non-invasive monitoring of treatment response and precise prediction of outcome.

Cell-intrinsic metabolic processes are dysregulated in acute myeloid leukemia (AML) and can act to sustain an oncogenic state of differentiation arrest. Using AML cell lines and patient-derived material grown in sophisticated liquid culture medium that mimics human plasma, we will perform metabolically focused in vitro and in vivo CRISPR-Cas9 screens to reveal metabolic regulators of AML cell fate that can be exploited via dietary or pharmacologic intervention as a novel therapeutic strategy.

The focus of my research is to elucidate the core molecular regulators of malignant stem cell generation in multiple myeloma. My approach addresses the tumor cell-intrinsic versus niche-dependent mechanisms of myeloma regeneration by exploring transcription factor expression and stemness profiles within single cells from primary samples and patient-derived models. The central goal of my research is to uncover novel therapeutic strategies and translate these into new myeloma treatments.

SIRPα+ macrophages mediate resistance to lenalidomide in B-cell lymphoma, limiting the activity of immunotherapy for these patients. Therefore, we propose a phase I/II study, investigating the safety and efficacy of ALX148, a novel fusion protein of the SIRPα binding domain, in combination with rituximab and lenalidomide in patients with B-cell lymphoma. We hypothesize that this combination will be safe and effective, providing a chemotherapy-free option for these patients.

Leukemia often results from aberrant gene expression caused by epigenetic alterations. Previously we discovered a novel histone acetylation reader domain in the ENL protein and demonstrated that this domain is essential for the survival of a wide range of acute leukemias, making it an attractive therapeutic target. We will develop specific inhibitors of ENL activity in acute leukemias and will use mouse models to define the role of ENL mutations identified in patients in leukemogenesis.

Our research program aims to gain a deeper understanding of the pathobiology of T-ALL and HSTL.

To this end, we will use novel mouse models, cutting-edge techniques and comprehensive genetic, pharmacological and metabolic interventions. In addition, we will perform unbiased experiments to identify novel therapeutic targets.

Our goal is to uncover new tools and targets for the treatment of T-ALL and HSTL, which could be used for the benefit of patients in the short/mid-term.

The long-term goal of my research program is to improve the outcomes for patients with high-risk myeloid blood cancers, particularly those with loss of chromosome 7 or CUX1. We are tackling this question using an arsenal of innovative methods and tools, including mouse models, human cells and patient samples, and state-of-the-art technologies to examine the cancer cell genome. Accomplishing this work will reveal new treatments and strategies for preventing blood cancers from arising.

My lab is focused on the immune regulatory mechanisms and ubiquitin-dependent machinery in lymphoma. We have established multiple high-throughput screening technologies and animal models to rapidly and accurately identify critical pathways that are suitable for targeted therapy and immunotherapy. Gaining insight into the pathological roles of these pathways can lead to improved understandings of the molecular circuitry that drives lymphoma pathogenesis and provide novel therapeutic strategies.

Our research program is focused on understanding the intersection between signaling and transcriptional dysfunction in myeloid leukemias. We leverage murine models, cell lines and human samples to uncover how biological context shapes the manifestation of oncogenic programs at the molecular level. Our long-term goal is to harness this knowledge to identify multipronged therapeutic strategies that improve outcomes for patients with myeloid malignancies.
