Alcor only does limited research in-house. Saul Kent is on Alcor's Board of Directors, and he's mostly responsible for most cryonics research, through many of his projects:
a) Suspended Animation Inc - Standby improvement, research into better equipment/meds, etc.
b) 21st Century Medicine Inc - Cryoprotectants, cooldown, cryobiology research
c) The Stasis Foundation and the Timeship project (www.timeship.org) - Building a cryonics/cryobiology research campus with a $375 million building, developing a Temperature Controlled Volume dewar (patented, based on work from Brian Wowk/21CM)
d) The Life Extension Foundation - Former CI president Ben Best is employed here to travel the world and perform research into various cryonics related technology
Besides Saul Kent's efforts, research is performed by Advanced Neural Biosciences Inc, a small company headed by Aschwin de Wolf in Oregon USA. They do research into the application of cryoprotectants and cryonics medication for both Alcor and CI.
In Russia there's also research being done by the people around KrioRUS, including Igor Artyuhov, and Yuri Pichugin who developed CI-VM-1 for CI in the past. Cryonics Institute performs limited in-house research, and Oregon Cryonics (a recently founded storage facility by Jordan Sparks, former CI Director) does the same.
This is about 85% of the cryonics research picture today if I'm correct. The rest consists of some individuals performing small cryonics research projects.
