Abstract

A 9-class differential diagnosis system for severe central nervous system infections, with primary amoebic meningoencephalitis (PAM) caused by Naegleria fowleri as the highest-stakes target class. Built in PyTorch on the RigoBERTa Clinical encoder, with a 5-model deep ensemble, dual-gate out-of-distribution detection (Mahalanobis plus logit-energy), and Mondrian per-class conformal prediction so coverage is controlled within each diagnostic class.

Key contributions
  • Dual-gate OOD detection combining Mahalanobis distance with a logit-energy criterion
  • Mondrian per-class conformal abstention so the model declines rather than guess on out-of-domain cases
  • 5-model deep ensemble over RigoBERTa Clinical for the 9-class differential

Organelle-Target Discovery for Selective Amoebicidal Therapy
L. Jordan Montenegro Calla
assaysmitochondriaNaegleria fowleri
Abstract

Matched HeLa+Nf vs Nf-only readouts across LDH (24 h), Caspase-3 (48 h), and JC-1 (72 h) to surface organelle-level dependencies that predict selective amoebicidal effect.

Key contributions
  • Plate-level assay design across three timepoints with matched co-culture controls
  • Reproducible analysis pipeline with documented per-plate QC

Montenegro's Medium: Low-cost Culture Formulation for Naegleria fowleri
L. Jordan Montenegro Calla
growth medialow-costNaegleria fowleri
Abstract

A serum-free, low-cost axenic medium that supports robust Naegleria fowleri growth at a fraction of the per-liter cost of standard formulations, with reproducible passage timing across replicates.

Key contributions
  • Three to five times increase in trophozoite yield versus the baseline reference medium
  • Cost-aware formulation with documented sourcing for each component
  • Reproducible protocol with QC checkpoints and stable passage cadence
