Master students
 |
Lotte Vogel (2017-) is working on using the lensing maps and the deep pixel-by-pixel color information in the Hubble Frontier Fields clusters to look at resolved stellar population analyses. |
PhD Students
 |
Daniel Lam (2015-) is a PhD candidate in the group, observing the first galaxies and modeling the gravitational lensing effect of galaxy clusters |
 |
Leindert Boogaard (2016-) is a student in the Bouwens group (and also in the group of Paul van der Werf), combining MUSE and ALMA data to understand galaxy formation in the early universe. |
 |
Arjen van Eltern (2017-) is pursuing a PhD on the AMUSE project with Simon Portegies Zwart, while also working with me to do the engineering of various modules in the near-IR pipeline for the future Euclid mission. Arjen is also working with postdocs Mher Kazandjian and Hugo Buddelmeijer on the Euclid project. |
 |
Sander Schouws (2018-) will be pursuing a PhD with me and with Renske Smit (Cambridge) and Jacqueline Hodge (Leiden) focused on future + existing ALMA observations of very high redshift sources to build on the success of Renske’s exciting Nature discovery. |
Postdocs
 |
Dr. Themiya Nanayakkara (2017-) is a postdoc in the team of Rychard Bouwens, Jarle Brinchmann, and Ivo Labbe. Themiya is an expert on the spectra of z=1-4 galaxies and has acted as a central postdoc in the ZFIRE spectroscopic program and possesses significant observing with MOSFIRE. |
 |
Dr. Bruno Ribeiro (2017-) is a postdoc in the team of Rychard Bouwens, Jarle Brinchmann, and Ivo Labbe. Bruno is an expert in both the spectra and morphologies of z=2-6 galaxies identified from the substantial VUDS program. |
 |
Dr. Mauro Stefanon (2018-) will join the Bouwens team in April 1, 2018. Mauro was previously a postdoc in Ivo Labbe’s research team iin 2014-2017, moved to New Haven to work with Pieter van Dokkum for a half year. During his earlier tenure in Leiden with Ivo, Mauro has provided the first-ever determination of the luminosity function (LF) of galaxies at rest-frame optical wavelengths. By comparing the evolution of the rest-frame optical LF with the evolution of the halo mass function, Mauro demonstrated that there is likely limited evolution in the stellar mass/halo mass ratio at z>=4. |
 |
Dr. Mher Kazandjian (2015-) is responsible for designing and implementing some of the algorithms that the European Science Ground Segment will use for reducing the near-IR observations from the future Euclid satellite. Mher is currently the chief programmer- developer for the Dutch contribution to the European Euclid effort. |
 |
Dr. Hugo Buddelmeijer (2017-) is helping with the engineering of various modules in the near-IR pipeline for the future Euclid mission. Hugo has significant scientific and programming experience designing an optical pipeline for the KIDS program and is using that experience to help with the engineering of the Euclid pipeline. |
Collaborators
In the Netherlands
Our group collaborates closely with other groups in Leiden and also in the Netherlands, particular, with those in Ivo Labbe‘s group, Marijn Franx‘s group, Paul van der Werf‘s group, Huub Rottgering’s group (specifically Jorryt Matthee), and Jarle Brinchmann‘s team. Michael Maseda, a NOVA postdoc in Leiden and now a member of JWST NIRSPEC team, is also a valued collaborator.
International:
On the topic of HST data and in future JWST data, the Bouwens group in Leiden maintains close collaborations with Pascal Oesch and Garth Illingworth.
On the ALMA side, the Bouwens group maintains good contact with the significant effort led by Fabian Walter, Chris Carilli, Manuel Aravena, and Roberto Decarli on the ASPECS observations over the HUDF, both the pilot program and new large program. Our Leiden-based team is a core collaborator in that effort.
Another key connection for our Leiden-based group is Roland Bacon at CRAL in Lyon and the larger MUSE GTO team.
