Medical Physicist · Scientific Solutions Engineer

Hi, I'm Luis.

I'm a medical physicist. My PhD at UW–Madison was on imaging pulmonary structure and function using MRI. I'm now a Senior Scientific Solutions Engineer at Flywheel, where I build imaging workflows for multi-site research studies. I live in North Carolina.

More about me

Research

Imaging lung structure and function with MRI.

My PhD work combined ultrashort echo time MRI, dynamic contrast perfusion and hyperpolarized xenon to follow diseases like idiopathic pulmonary fibrosis over time.

  • Motion compensation for free-breathing UTE lung MRI
  • DCE-MRI perfusion in IPF and prematurity
  • Hyperpolarized 129Xe gas-exchange imaging

Engineering

Building the tools that run imaging research.

At Flywheel I design containerized imaging workflows used across multi-institution studies, and partner with research sites to turn their algorithms into validated, automated pipelines.

  • Imaging workflows across MRI, CT, PET and ophthalmic data
  • Physics-informed scan classification for MR, CT and PET
  • Fine-tuning medical foundation models (MedSigLIP)
