Krystal Biotech1University of Pittsburgh2

  • 1Bioprocess Engineer I, cGMP gene therapy manufacturing, 2025 to present
  • 2B.S. Computational Biology, 2023; research in the Byrne and Liu labs, 2020 to 2025

Highlights

  • Co-first author of a 2026 Scientific Reports study measuring vision in OCA1 mice
  • Designed and purified AAV gene therapy vectors for retinal disease in the Byrne Lab
  • Simulated de novo designed heme enzymes with AMBER molecular dynamics

In brief

Wyatt Kriebel works across molecular biology, computation and manufacturing. At the University of Pittsburgh he spent five years on AAV gene therapy for oculocutaneous albinism type 1, purifying vectors and building the behavioral assays used to measure vision in OCA1 mice, and later simulated de novo designed enzymes with molecular dynamics. He now manufactures gene therapies under cGMP at Krystal Biotech.

Projects

Sidechain

Browser game for biochemistry teaching

A daily five-residue peptide puzzle for undergraduate biochemistry, with a scaffolded high-school mode. Guesses are scored on side-chain chemistry rather than letters, and solving reveals the real protein motif you built.
