abstract = "In this talk I will present our work on two projects relevant to quantum sensing and imaging in the context of chemistry and biology. First, I will discuss an experimental demonstration of a new kind of super-resolution microscopy modality that in principle saturates the quantum Fisher information associated with resolving mutually incoherent point sources. The method could find utility in cases where simultaneously emitting point sources are to be continuously tracked, or when the size and/or aspect ratio of a subdiffraction object is to be accurately and efficiently assessed. Second, I will share how our group has repurposed commonly-used Alexa dyes as photoswitchable spin beacons that can be interfaced with single nitrogen-vacancy (NV) centers in diamond for correlative optical-magnetic resonance microscopy. This offers a possible way forward in the development of a general method for single-molecule nuclear magnetic resonance (NMR) spectroscopy. In this paper I will briefly summarize our findings on both topics, then expound upon some of the theory and simulation used to model the latter.",
