Kesshi Jordan is a Staff Data Scientist with 12 years of experience bridging neuroimaging research and production health analytics, currently applying clinical ML at Thyme Care. Trained as a bioengineer with a PhD from UCSF/UC Berkeley, they built novel diffusion MRI tractography pipelines to model brain connectivity in extreme pathologies and automated workflows now used to inform neurosurgical and radiation therapy decisions. In industry roles at Octave and Rally Health they led cross-functional teams to turn clinical intuition and large-scale medical transaction data into actionable, cost-aware population health solutions. An active open-source contributor to flagship projects like DIPY and Nipype and a developer on the VTK-based FURY renderer, Kesshi blends deep domain expertise with practical software engineering and technical writing. They have a knack for repurposing algorithms—evidenced by an Insight Fellowship project that used nonlinear time-warp features from speech recognition to screen for neurodegeneration—making complex models interpretable to clinicians.

Workflows and interfaces for neuroimaging packages
Role in this project:
Data Scientist
Contributions:99 commits, 5 PRs, 63 comments in 2 years
Contributions summary:Kesshi primarily contributed to the `nipype/nipype` repository by fixing bugs and adding interfaces related to neuroimaging data processing. They modified existing code to correct the functionality of a `GradientTable` object. The user implemented new interfaces for calculating the anisotropic power map using `dipy` library. Also, the user added interfaces for the `dtitk` command-line tools, integrating additional tools into the existing framework.
