Prior to CISAC, Lindsay was a Stanton predoctoral fellow in the Nuclear Policy Program at the Carnegie Endowment for International Peace. In her time at UMD, she was also the instructor of record for an undergraduate nuclear policy course and the Catherine Kelleher research fellow at the Center for International And Security Studies at Maryland (CISSM). Lindsay also has experience working as an adjunct research associate at the RAND Corporation, a research associate at the Center for Global Security Research at Lawrence Livermore National Lab, a NSF fellow on the DHS Science and Technology Directorate quantum technology task force, and a research intern at the Naval Research Laboratory.

Her research draws on her interdisciplinary background in physics and policy to explore how social, political, and technological changes have contributed to the cyclical reconception of "vulnerability" in nuclear strategy and policymaking. In her dissertation, she analyzed the implications for nuclear deterrence due to quantum sensing, and leveraged technical analyses and historical case studies of previous emerging technologies to develop an integrated socio-technical analytic framework.
