About the role

Research Scientist position in the CBRNE team within the Responsible Development and Innovation (ReDI) group focused on evaluating and mitigating safety risks of frontier AI models in the radiological domain.

Responsibilities

  • Construct threat models prioritizing vulnerabilities, threat actors, and scenarios related to fission, fusion, thermonuclear weapons development, and high-energy-density dual-use regimes.
  • Create evaluation datasets of complex physics and nuclear engineering prompts to elicit the maximum capability of the model to determine how to uplift malicious actors across the domain.
  • Collaborate with engineers to design mitigations that block harmful outputs without overly degrading the model's scientific utility.
  • Support development and refinement of Google’s nuclear safety policy. Communicate complex risks, evaluation findings, and mitigation strategies to leadership and technical/non-technical external stakeholders.
  • Develop mathematical and computational frameworks to quantify capability thresholds, technical feasibility, and potential consequences of model uplift wherever possible.

Qualifications

  • PhD and Postdoctoral research experience in Particle Physics, Plasma Physics, Nuclear Engineering, or a related field.
  • 3 years of experience in research with US national laboratories or security initiatives (e.g., IAEA, NNSA, DARPA, or academic consortia).
  • Experience in research or policy in radiological/nuclear security, safeguards, nonproliferation, material control, or threat reduction.
  • Experience in radiation/neutron transport, reactor monitoring, detection, dosimetry, shielding defeat, and RDD/RED mechanics.
