About

Turning tumor biology into preclinical therapeutics.

I lead translational research at the intersection of metabolism, immunology, and cancer — designing the in-vivo models and screening programs that move promising molecules toward the clinic.

I'm a senior scientist with deep expertise in in-vivo drug screening, solid tumor oncology, and preclinical efficacy studies. My career has centered on the hardest questions in pancreatic cancer — how obesity, chronic stress, and inflammation converge to drive tumor initiation and progression.

As co-head of the Pancreatic Cancer Translational Laboratory at UCLA, I combine sophisticated murine models with computational biology and digital pathology to identify actionable targets and repurpose approved drugs as chemo-preventive agents. Earlier, I played pivotal roles developing the anti-metastatic compound Metarrestin and the immunomodulatory peptide RP-182.

In-Vivo & Laboratory Methods

Complex murine model generation (inducible KrasG12D), high-throughput phenotypic screening, target deconvolution, flow cytometry, and tumor microenvironment modulation.

Bioinformatics & Programming

Python and R for genomic/transcriptomic analysis of FASTQ sequencing data, statistical computing, experimental modeling, and data visualization — accelerated with cloud and AI tooling.

Digital Pathology & Imaging

Advanced QuPath workflows for quantitative digital pathology, automated IHC quantification, and biomarker evaluation (e.g., GLP1R).

Research Focus

Three questions driving my work.

My research program spans the biology of pancreatic cancer, the development of first-in-class therapeutics, and the computational tools that make discovery faster.

01

Metabolism, stress & PDAC

Investigating how diet-induced obesity and chronic stress converge on CREB phosphorylation to accelerate pancreatic cancer — and how approved drugs like metformin, statins, and beta-blockers might interrupt early carcinogenesis.

First-in-class therapeutics

Preclinical development, screening, and target deconvolution of novel oncology compounds — including the anti-metastatic agent Metarrestin (ML-246) and the CD206-targeting host-defense peptide RP-182.

Tumor immunology

Characterizing macrophage-driven acinar-to-ductal metaplasia and inflammatory cytokine production to uncover immunotherapeutic vulnerabilities and reshape the pancreatic tumor microenvironment.

Projects

Building the tools I need at the bench.

Beyond wet-lab research, I design and build computational tools — native applications and interpretable machine-learning pipelines that turn raw biomedical data into decisions.

PaNIN Detector

Native macOS · Digital Pathology

A Mac app for studying pancreatic pathology slides. It lets you view huge microscope images, mark up regions by hand, and train AI models that learn to spot early pancreatic lesions (PaNIN) on their own.

  • Smoothly view enormous slide images, zooming from the whole slide down to individual cells.
  • Draw and label regions by hand, saved in a format that opens directly in QuPath, a standard pathology tool.
  • Plug in different AI models — Apple's built-in Vision or specialized pathology models (UNI, Virchow, CTransPath).
  • Train a model, check how well it did, see the patterns it learned, and run it across a slide to highlight suspected lesions.

UpDown Analysis

Signal Processing · Machine Learning

One simple, fast method for reading medical signals. It breaks any waveform into its up-and-down segments, turning the shape into features a computer can learn from — applied to two problems: reading heart tracings (ECG) and spotting seizures in brain activity (EEG).

  • Heart (ECG): tells normal tracings from abnormal ones with 91% accuracy — nearly matching deep neural networks, but with results you can actually explain.
  • Heart (ECG): works on patients from three countries across two continents, plus a plain-English summary of each tracing and a tool that turns a photo of an ECG into usable data.
  • Brain (EEG): detects seizures in new patients with 89% accuracy — beating the standard approach, while staying light enough to run on wearable or implanted devices.
  • Trustworthy by design: every result was stress-tested to rule out "too good to be true" numbers, and the method is as lightweight as detectors used in FDA-approved implants.
