Who We Are

Alessandra Aloisi [aloisi@stsci.edu]
Alessandra Aloisi joined Space Telescope Science Institute as a post-doc in July 1999. She is working with Claus Leitherer on different properties of the star formation process in local irregular galaxies. Her principal research project is a detailed analysis of the stellar content and star formation history of some peculiar local star-forming dwarfs in order to apply chemical evolution models to each individual system. This will allow us to connect spectro-chemical-photometric properties of local dwarf systems with those of high redshift galaxies. In October 2003 she accepted a STIS Instrument Scientist position with ESA.

Rupali Chandar [rupali@stsci.edu]
Rupali Chandar joined STScI as a postdoc in spring 2002. She is working with Claus Leitherer on understanding the properties of 19 nearby starburst galaxies from far- and near- ultraviolet STIS spectroscopy. The goals of this project include a detailed look at the stellar content and the relationship between stellar properties and the ISM in these local starbursts. Additional research interests involve characterizing the young, massive star cluster populations in late-type galaxies, and their relationship to the super star clusters found in starbursts.

Julia(Zhuhui) Chen [zchen@stsci.edu]
Julia Chen has a degree in Information Systems. Julia began working with STScI in the spring of 2002 as an intern under Claus Leitherer. She is currently working as an IT consultant on various web pages and cgi resources for the Starburst group.

Duilia de Mello [duilia@ipanema.gsfc.nasa.gov]
Duilia de Mello was a post-doc at Space Telescope Science Institute from May 1997 until 1999. Meanwhile, she moved to Goddard Space Flight Center to support the GOODS project. Nevertheless, she is still maintaining her ties with STScI. Her main research interests involve: the role of evolution in galaxy properties; the environmental effects in galaxy evolution/formation; the properties of star-forming galaxies at low and high redshifts; the starburst/AGN connection. Her main goal is to construct a robust method to analyse the stellar population of star-forming galaxies at high redshift.

Daniel Devost [devost@astro.cornell.edu]
Daniel Devost did his Phd Thesis with the Université Laval in Quebec City, and the Space Telescope Science Institute (STScI). His main scientific interests lie in the study of the effects of star formation and their relation with the physical properties of galaxies. He is studying starburst galaxies which are a unique "laboratory" to understand the dynamics of star formation and its impact on the ISM of galaxies. Currently he is a postdoctoral fellow with the SIRTF IRS Team at Cornell.

Joao Rodrigo Souza Leao [souza@stsci.edu]
Joao Rodrigo Souza Leao has joined the STScI as a PhD student in August 2002, reporting to Claus Leitherer. The goal of his thesis is to study the statistics of Wolf-Rayet stars in high-metallicity starburst galaxies. Observations of an infrared-selected sample of starburst galaxies in the optical and near-IR are currently being collected. The data will be used to study how the IMF depends on metallicity, and to investigate the stellar content and test stellar evolution theory in high-metallicity environments.

Claus Leitherer [leitherer@stsci.edu]
Claus Leitherer has been with STScI since 1988. He is currently Associate Astronomer in the JWST Division. His prime responsibility is the support of MIRI. He is also a member of the Cosmic Origins Spectrograph IDT, a future HST instrument which will be installed in 2006. Main scientific interests are atmospheres and evolution of hot stars, resolved and unresolved massive stellar populations, the stellar content and interstellar medium of star-forming galaxies, starburst activity in galaxies, and spectrophotometric evolution models of galaxies.

Lucimara Martins [martins@stsci.edu]
Lucimara Martins joined STScI as a Ph.D. student in May 2002. She is working with Claus Leitherer on the interpretation of low-luminosity AGN with nuclear and circumnuclear starburst contribution. The goal of the thesis is to use photoionization models to identify the main processes powering the emission lines in these objects: radiation from hot stars, shocks resulting from winds and supernovae, or accretion onto the central black hole. Ground-based spectra of about 40 AGN have been collected and will be used to test the photoionization models.

Daniel Schaerer [schaerer@ast.obs-mip.fr]
Daniel Schaerer used to work at STScI, where he was instrumental in implementing the isochrone synthesis technique in Starburst99. Currently he is at the Observatoire Midi-Pyrenees (France). Main scientific interests are massive star populations in starburst galaxies and their relation to stellar evolution aspects, in particular to Wolf-Rayet stars. His website can be visited at Massive Stars in Galaxies.

Christy Tremonti [tremonti@as.arizona.edu]
Christy Tremonti was a PhD student at Johns Hopkins University in Baltimore. She is working with Daniela Calzetti, Claus Leitherer, and Tim Heckman on the structure and evolution of starburst galaxies. Her main focus is on the importance of inhomogeneities in interpreting starburst phenomena. She is presently working on a detailed analysis of the structure and kinematics of several local starbursts, using both optical and ultraviolet spectra. In spring 2003 she moved to the University of Arizona as a postdoctoral fellow.

Gerardo Vazquez [vazquez@stsci.edu]
Gerardo Vazquez joined STScI as a postdoc in fall 2001 to work on spectro-chemical evolution of galaxies. As part of his Ph.D. thesis, he developed a new chemical evolution code. His main interest are stellar populations in late-type and low-surface-brightness galaxies. Currently he is most interested in chemical aspects of massive stars, including supernovae, and how they relate to chemical evolution models of starburst galaxies.
