Putting circulating tumor DNA into a mechanistic framework

December 11, 2020

We developed a stochastic mathematical framework to study tumor growth and circulating tumor DNA (ctDNA) shedding to predict the potential and limitations of ctDNA for cancer early detection. We found that ctDNA can detect tumors earlier with higher specificity than other methods. The framework will help to accelerate clinical trials by identifying the most promising cancer early detection strategies. Read the full study in Science Advances.


Analyzing metastatic spread through a forest of phylogenies

May 25, 2020

In our new study, we developed a mathematical framework to analyze cancer phylogenies. In collaboration with the lab of Kamila Naxerova, we found that lymphatic and distant mets spread very differently and exhibit very different levels of heterogeneity. Nature Genetics article PDF


New study on ctDNA-based cancer early detection via liquid biopsies

February 14, 2020

We developed a mathematical model of cancer evolution and ctDNA shedding to predict the tumor detection size across different screening strategies with liquid biopsies. Available as a preprint: A mathematical model of ctDNA shedding predicts tumor detection size. bioRxiv

Presented ctDNA model at AACR Special Conference Advances in Liquid Biopsies

January 14, 2020

We presented our newest results on ctDNA-based cancer early detection in a plenary talk at the AACR Special Conference Advances in Liquid Biopsies during the Plenary Session 1: Early Detection with ctDNA on Tuesday, January 14, 2020 in Miami. We also present a poster at the Poster Session A.

Homogeneity of predicted functional mutations in driver genes

August 27, 2019

In a reanalysis of intratumoral heterogeneity in untreated cancers featured on the cover of Nature Reviews Cancer, we find that homogeneity of predicted functional mutations in driver genes is the rule rather than the exception. We also show that in most patients a single biopsy of a primary tumor captures the information necessary for initial therapeutic decision making. Nature Reviews Cancer article PDF


Consecutive seeding of metastases
