Research Interests

Dynamic, complex systems of interacting components underlie many challenges humanity faces, including healthcare, financial market stability, social policy, and climate change. I have always been fascinated by such systems, and my professional life is dedicated to understanding complex systems to address problems of significance.

My research has focused on the evolutionary dynamics of a variety of biological systems, from microbes to cancer. My graduate work was focused on applying this deeper understanding to the discovery of novel antibiotics and microbial enzymes for biofuels production. After completing my doctorate, I have focused my attention on using knowledge of population dynamics to design non-invasive diagnostics to monitor the impact of treatment on cancer progression.

To enable this research, I have continually expanded my knowledge of the tools necessary to understand these systems. These include cutting edge genomics approaches, machine learning, and Julia package development.

Professional Experience

Scientist II

2020 - Present
Murtaza Lab - University of Wisconsin-Madison

Moved with the Murtaza lab to UW-Madison to continue non-invasive diagnostics development.

Computational Scientist II

2016 - 2020
Murtaza Lab - Translational Genomics Research Institute

In the Murtaza Lab I developed the computational pipeline and contributed to wet lab development of a highly sensitive method for detecting patient-specific tumor mutations from as little as 5ng of plasma derived DNA.

Doctoral Candidate

2010 - 2016
Currie Lab - University of Wisconsin-Madison

My thesis focused on the evolution of bacterial diversity and function across a range of phylogenetic scales. In particular, I investigated on the evolutionary dynamics of natural product biosynthesis clusters across the genus Streptomyces and within a single population of fungus growing ant-associated Pseudonocardia. My graduate work contributed to 12 publications.

Research Assistant

2009 - 2010
Dunckley Lab - Translational Genomics Research Institute

My project was focused on exploring the impact of autophagy on Tau protein degradation in Alzheimer's Disease, using siRNA experiments in cell lines and mouse-derivied primary hypocampal neurons.

Research Assistant

2007 - 2009
Moran Lab - University of Arizona

I investigated the genomic diversity of the most extreme bacterial genomes, the ultra-small genomes of cicadas and other plant sap feeding insects. My work contributed to three publications.

Selected Projects

I have worked on a diverse range of research projects applying evolutionary theory to problems of practical importance, in both leading and collaborative roles. These have included cancer biomarker detection, antibiotic discovery, and enzyme discovery for improved biofuels production. Projects in which I have played a leading role include:

Minimal residual disease detection from cell-free tumor DNA in breast cancer (Science Translational Medicine) - Responsible for all aspects of computational development for a highly sensitive method to detect patient-specific tumor mutations from a single tube of plasma.
Lateral gene transfer dynamics in the ancient bacterial genus Streptomyces (mBio) - Used a combination of phylogenetic tools and comparative genomes to explore LGT dynamics in the genus Streptomyces, a critical source of natural products.
Population Genetics of Defensive Mutualist Pseudonocardia (BioRxiv) - Used population genetic tools to investigate the impacts of host biogeography and selection on the diversity of fungus growing ant associated Pseudonocardia.
