-   Gary J. Ferland (University of Kentucky)

Gary began working on Cloudy at the Institute of Astronomy, Cambridge with the goal of performing a true simulation of non-equilibrium matter in various  astronomical environments.  He is coauthor, with Don Osterbrock, of the current edition of Astrophysics of Gaseous Nebulae.

- ‚ÄčChristophe Morisset (Instituto de Astronomia - UNAM, Mexico)

Christophe Morisset works with photoionization codes for more than 25 years, performing models of Novae, Planetary Nebulae, and HII regions. He developed the pyCloudy library to allow easy use of the Cloudy code, include a pseudo-3D module. He also developed the PyNeb package, used to determined physicochemical conditions of ionized nebulae. He managed the MySQL database 3MdB, that provide free online access to more than 700,000 models. To know more about Christophe's research please visit his homepage." 


- Peter van Hoof (Royal Observatory of Belgium)

Peter is a co-developer of the Cloudy code. His research interests include modeling dust and ionized and molecular gas in planetary nebulae. He is also interested in the late stages of evolution of intermediate mass stars, and more in particular, following that evolution in real time. For further information please visit  here.


- Ravi Sankrit (Space  Telescope Science Institute)

Ravi used Cloudy for modeling the emission from HII regions as part of his doctoral thesis.  Since then he has used the code for modeling Planetary Nebulae, the diffuse interstellar medium around hot white dwarf stars, and most recently, nova shells.  He has guided several student-intern research projects based on running Cloudy.  His research uses imaging and spectroscopic observations of various emission line objects at ultraviolet, optical, and infrared wavelengths.  For further information visit his <homepage>.
