About me
I am a translational R&D leader focused on moving oncology diagnostics and drug-development programs from scientific rationale to decision-ready evidence. My work spans biomarker strategy, assay development, analytical validation, molecular diagnostics, preclinical pharmacology, and development-focused R&D planning.
As Senior Vice President, R&D at Episteme Prognostics, I lead R&D strategy for precision-oncology diagnostics while continuing to apply a practical operating model built around experimental rigor, CRO/vendor coordination, reproducible analysis, SOPs, QC frameworks, and regulatory-readiness documentation.
Translational & Preclinical Development
Model strategy, mechanism-of-action studies, in vivo pharmacology, lead-optimization support, and nonclinical planning.
Biomarkers & Molecular Diagnostics
Biomarker discovery, analytical validation, IHC, chromatin accessibility, NGS, liquid biopsy, and CDx-relevant assay development.
Rigorous Program Execution
Quality by Design, reproducible Python workflows, statistical process control, CRO coordination, SOPs, and QC systems.
Regulatory & Development Planning
RAC-Drugs credentialed; nonclinical and IND-enabling planning, CLIA/CLEP documentation, and CRO and vendor oversight.
Career
Translational R&D leader with 12+ years across oncology, molecular diagnostics, biomarker development, preclinical drug discovery, and rigorous program execution, with work spanning pancreatic, lung, and thyroid cancers.
Lead R&D strategy for precision-oncology diagnostics, focused on pancreatic cancer and chromatin-accessibility-based biomarkers. Set scientific priorities, experimental plans, and development milestones across biomarker research, assay development, analytical validation, and clinical translation; coordinate laboratory leadership, clinical collaborators, bioinformatics, and external partners. Previously advanced two laboratory-developed tests, an HNF1B IHC assay and a chromatin-accessibility (ATAC) assay, from discovery through analytical validation and New York State CLEP submission. Authored SOPs, validation plans, and CLIA/CLEP-aligned QC frameworks establishing input requirements, precision criteria, traceability controls, and objective assay acceptance thresholds. Coordinated a four-site prospective validation study extending the chromatin-accessibility workflow from resected tissue to fine-needle biopsy specimens.
Supported early-stage small-molecule development in women's health, spanning assay strategy, pharmacology, lead optimization, and nonclinical planning. Developed translational assays and preclinical study strategies supporting compound characterization and candidate selection, contributed to nonclinical and IND-enabling planning including study design, budget estimates, and external-study coordination, and helped establish laboratory workflows, vendor relationships, and scientific documentation for an early-stage biotechnology company.
Led preclinical drug-discovery efforts in pancreatic ductal adenocarcinoma (PDAC) to improve the efficacy of epigenetic therapies and immune checkpoint inhibitors. Built multi-cell co-culture systems modeling the tumor–immune microenvironment, executed orthotopic in vivo studies with survival endpoints, and integrated flow cytometry, cytokine profiling, and RNA-seq. Showed that low-dose dual epigenetic therapy combined with anti–PD-1 reverses an HMA-induced suppressive myeloid phenotype and prolongs survival in an orthotopic PDAC model.
Led NSCLC studies that uncovered a previously unrecognized role for the CTLH E3 ubiquitin ligase complex (the RANBP9/RANBP10 "rheostat") in tumor progression and therapy resistance. Generated multiple GEMMs and 20+ stable isogenic cell lines powering mechanistic studies and high-throughput screening; findings established RANBP9/RANBP10 as candidate therapeutic targets and linked RANBP9 to platinum sensitivity and a PARP-inhibitor "BRCAness-like" vulnerability.
Identified AGC-family kinases, notably SGK1, as essential, AKT-independent drivers of PI3K-driven thyroid cancer survival. Established primary thyrocyte cultures, generated 20+ engineered cell lines, and supported 100+ in vivo and in vitro studies, including industry collaborations to screen and validate small-molecule kinase inhibitors.
