The Project Director has overall leadership responsibility for the execution of the work and for meeting the science requirements within schedule and budget. Lucas is responsible for setting the strategic vision and priorities for the project. He acts as the main point of contact with NSF, AURA Corporate, and the NOIRLab Director’s Office and represents the program in both internal and external committees and in public settings. 

Macri earned a BS in Physics from MIT in 1995 and a PhD in Astronomy from Harvard in 2001. He held Hubble and Goldberg postdoctoral fellowships at the National Optical Astronomy Observatory (NOAO) before joining the Department of Physics and Astronomy at Texas A&M University in 2008. The primary focus of his research has been in the extragalactic distance scale, using Cepheids and Miras to calibrate the luminosity of type Ia supernovae and measure the Hubble constant with the NASA/ESA Hubble Space Telescope and the James Webb Space Telescope. He has also worked on the optical follow-up of gravitational-wave sources, all-sky redshift surveys, searches for exoplanets, and time-domain surveys using infrastructure in Antarctica.

The Systems Scientist (SS) is responsible for setting the scientific strategic vision for the Project Systems Engineering team and addressing proposed changes to the Project technical baseline along with the Systems Engineering Manager and Systems & Software Architect. The SS is responsible for ensuring that the overall US-ELTP user services meet the expectations of the relevant stakeholders and the project is using consistent and correct scientific terminology. They bridge the gap between the project-wide vision for community engagement and the engagement activities coordinated by the Stakeholder Representatives.

The Interim Project Manager (PM) is responsible for managing the execution of all programmatic activities, including developing and managing the project budget, schedule, scope, and risk; closely collaborating with program and technical teams at TMT and GMT; interfacing with other NOIRLab programs such as Rubin, Gemini, and CSDC; and representing the US-ELTP to stakeholder groups in reviews and other venues. 

Marie holds a PhD in Astrophysics from the Université de Toulouse (France; 2003). She held a two-year postdoctoral position at the Institute of Astronomy at Cambridge (UK) and a three-year UK Gemini support scientist position in the UK National Gemini Office at the University of Oxford. Marie joined the Gemini Observatory in 2009 and provided observatory support duties at the Gemini Observatory in Hawai'i. Marie’s research interest focuses on galaxy formation and evolution through the study of physical properties of spatially resolved distant galaxy populations using mostly adaptive optics and integral-field spectroscopy in the optical and infrared.

The role of the Community Engagement Scientist (CES) is to ensure that everyone has an equal opportunity to access GMT and TMT, regardless of their origin, affiliation, career stage, etc. The CES is responsible for developing and executing the overall vision for community engagement in the Design, Development, and Construction Phases of the project. The CES is also responsible for building and maintaining relationships with stakeholders to increase awareness of and support for the US-ELTP.

André-Nicolas is an associate astronomer at NOIRLab. He completed his PhD at the Université de Montréal in 2007 and learned everything about the fundamentals of astronomical observations at the Observatoire du Mont Mégantic. He was research fellow at the NRC Herzberg Astronomy and Astrophysics Research Centre and postdoc jointly at the Universidad de Concepción and the Universidad de Valparaíso before joining the Gemini Observatory (now a program of NOIRLab) in 2013. For almost 10 years, André-Nicolas took part in every phase of a Gemini observing program life cycle and has played a central role in Gemini's user support effort. André-Nicolas’s research interests are massive stars, hot winds, star clusters, and stellar evolution.
