Siam Oottamasathien

Siam Oottamasathien is a Professor in the Department of Urology at Harvard Medical School, leading an active research laboratory at Boston Children's Hospital. His work bridges urologic research and clinical innovation with a primary focus on interstitial cystitis/painful bladder syndrome (IC/PBS) affecting 3.2-7.9 million US women.

His research targets the inflammatory cascade mechanisms in IC/PBS, particularly investigating cathelicidin (LL-37) as a trigger for bladder inflammation, pain, and fibrosis. Key areas include:

• Mast cell activation pathways in bladder pain
• Development of non-opioid analgesics using sulfated glycosaminoglycan ethers (SAGE)
• Thermoresponsive silk-elastinlike polymers for sustained drug delivery
• Mechanistic studies of radiation-induced proctitis

Analysis of his publication record (2017-2022) reveals a consistent focus on glycosaminoglycan-based therapeutics and inflammatory mechanisms across urologic and radiation injury contexts, with significant emphasis on translational biomaterial applications.

Scientific recognition includes:

• NIH R01 grant (R01CA227225-01A1) for radiation proctitis research

The laboratory actively recruits post-doctoral MD/PhD researchers and senior research associates, indicating ongoing mentorship activities. Current projects include mechanistic studies of LL-37 in IC/PBS pathogenesis and optimization of SAGE delivery systems for radiation injury. The Oottamasathien Laboratory operates within Boston Children's Hospital's Department of Urology, utilizing proprietary murine models to bridge bench-to-bedside therapeutic development for chronic urologic conditions with no current effective treatments.
