The Center for Interdisciplinary Exploration and Research in Astrophysics (CIERA) at Northwestern University invites applications for a special endowed research position: the CIERA Board of Visitors Research Associate. The position was created in support of CIERA’s director, currently Prof. Vicky Kalogera. This is a 3-year term position with the possibility of longer-term renewal based on satisfactory performance and the availability of funding. The nominal starting date will be September 1, 2025, but a different start is negotiable depending on the applicant's availability. Application deadline: August 15th, 2025.

The Board of Visitors Research Associate will work closely with the director and will have broad responsibility for maintaining the research program of the Director of CIERA, working on proposals, and interacting with the Board of Visitors. The position is a PhD-level, research associate and science manager position. Named for the CIERA Board of Visitors, whose generous donations fund the role, the position is at a similar level to a postdoctoral associate. Depending on prior experience, the possibility of advancement to the research faculty track is available.

Overall Responsibility: The Research Associate will be responsible for scientific planning and progress tracking, proposal preparation, reporting, outreach, and student mentoring and training. Principal duties and responsibilities include:

Manage the Director’s research group activities, including leading group meetings and managing shared group resources.
Prepare materials for presentations, proposals, reports, and manuscripts with the director and other group members.
Scientific communication, including research presentations at national and international meetings, and public outreach.
Maintain and update documentation on the Director’s and group’s activities, such as publications, funding, and more.
Interface with other relevant groups and efforts at CIERA, other NU centers and departments, and the SkAI Institute, on behalf of the Director’s research group and projects.
Regularly interact with the CIERA BoV members about group and other research news.
Mentor students at different levels of their research studies.
Up to 20% research time, independent or in collaboration with the director’s group members.

This position will be part of the Center for Interdisciplinary Exploration and Research in Astrophysics (CIERA) at Northwestern. Successful applicants will benefit from interaction with a broad interdisciplinary group of researchers and will be immersed in a diverse and dynamic intellectual environment (learn more about CIERA’s programs and activities). The BoV Research Associate will have access to three exclusive high-performance computer clusters, providing access to 6,924 compute cores. Additional HPC resources, including high-memory nodes, are available through Northwestern’s Quest cluster (see ciera.northwestern.edu/high-performance-computing for more information). A dedicated Computational Specialist is also on staff to assist CIERA researchers.

A PhD in Astronomy, Astrophysics, or Physics is required. Background in any of stellar structure and evolution, compact-object astrophysics, gravitational-wave sources and data analysis is highly desired. No formal research program management experience is required, but strong evidence for research excellence, multi-tasking, and organizational skills is highly desired. Must be able to handle a variety of tasks, to effectively solve problems, and to shift priorities as needed. The candidate must be self-motivated, energetic, and able to work independently, bring projects to conclusion, and have the interpersonal skills to work effectively with collaborators, students, administrators, and grant sponsors.

The determination of the equation of state and composition of ultra-dense matter from multi-messenger astrophysical observations remains a central challenge in nuclear physics and high-energy astrophysics. Within this context, the LuTH-Caen theory group, as part of the Virgo collaboration, itself part of the LIGO-Virgo-KAGRA consortium, has established a recognized expertise in the theoretical modeling of ultra-dense stellar matter and the development of advanced statistical methods for quantifying theoretical uncertainties and their impact on the confidence intervals of astronomical observables.

Application Deadline: March 27th 2025

This postdoctoral project aims to generate quantitative predictions for the key parameters governing the emission of detectable gravitational wave signals from compact objects, incorporating the uncertainties inherent in the underlying microphysics. Specifically, the successful candidate will focus on parameter estimation in one of two contexts: neutron star binary coalescence, either during the inspiral or post-merger phase, or the continuous gravitational waves emitted by isolated neutron stars.
Within this framework, the successful candidate will contribute to the interpretation of signals from past and ongoing LVK observational campaigns, as well as to the preparation for third-generation interferometers, including post-O5 and the Einstein Telescope. The research will specifically aim to constrain the microscopic properties of dense hadronic matter, such as the nuclear equation of state, and to identify potential signatures of deconfinement phase transitions.

Activities

The successful postdoctoral fellow will be responsible for maintaining and further developing the Bayesian analysis tools for equation-of-state inference within the LPC theory group. This work will be carried out in close collaboration with group members from GANIL and the Strasbourg Observatory, the latter being conducting numerical relativity simulations of post-merger remnants. Depending on the candidate’s previous research experience and interests, there may also be opportunities to contribute to the group’s theoretical developments related to the modeling of dense and superfluid matter in neutron stars. The candidate is expected to contribute to research activities and topics such as:

• Development of the CUTER tool for the improvement of parameter estimation using microphysics informed equations of state, see https://zenodo.org/records/10781539
• Numerical simulations for the physics case prospects of third generation interferometers
• Theoretical modelling of the zero and finite temperature nuclear equation of state and its possible phase transitions, with both effective and microscopic models
• Development and analysis of neutron star cooling simulations and applications to the measurable properties of the neutron star crust

Skills

The successful candidate must have a PhD in theoretical nuclear physics, gravitational wave data analysis or numerical hydrodynamics. Proficiency in scientific programming (C, C++, Python) and numerical simulations is expected. Familiarity with software development tools such as git and gitlab, while not essential, would be an advantage.

Work Context

The successful candidate will be assigned to the theory and phenomenology team, within the Corpuscular Physics Laboratory of Caen.
The team has a longstanding experience in theoretical nuclear modelling. Since 2020, it is part of the Virgo collaboration within a theoretical group including researchers from the astronomical observatory in Strasbourg, and the GANIL laboratory in Caen.
The LPC CAEN, with about 100 staff, is a joint research unit (UMR 6534) under the supervision of three institutions: the CNRS, the University of Caen Normandy (UCN) and the Ecole Nationale Supérieure d’Ingénieurs de Caen (ENSICAEN). It is located on Campus 2 of the University of Caen (Campus Côte de Nacre) and is part of the research park of ENSICAEN (www.lpc-caen.in2p3.fr/).
