Projects

A concise list of projects beyond the publication record—software, engineering work, and exploratory efforts.

NovaSSM

Shape modeling sandbox

A PyTorch reimplementation of the ShapeWorks optimizer as a sandbox for trying new loss functions and approaches to shape modeling. Autograd removes the need to write gradients by hand, and Python makes it faster to prototype ideas than extending the full ShapeWorks backend.

ShapeWorks

github.com/SCIInstitute/ShapeWorks

At the SCI Institute I contributed to ShapeWorks, an open-source suite for automated construction of compact statistical landmark-based shape models. I led implementation of shape modeling for arbitrary regions of interest—a research problem with substantial engineering depth.

Cryo-electron microscopy

Automated grid screening

Worked on automating single-particle cryo-EM grid screening with deep learning. We built a dataset with collaborators, wrote a Python/Tkinter GUI for collecting quality labels, and trained a quality-assessment network to predict labels for grid areas. See also the MICCAI 2020 paper.

EXXON CUDA GPU

Industry collaboration

Proprietary work for ExxonMobil writing CUDA code to accelerate research software for modeling geological features.

Personal & exploratory software
