Neuroscientist studying memory, decision-making, and neural coordination

I am a postdoctoral fellow at NYU’s Center for Neural Science working with Dr. André Fenton. I received a B.S. in Cognitive Science and a B.A. in Spanish Literature from UC Irvine in 2015. I then earned my PhD in Psychology from UCLA (2021) working with Dr. Tad Blair, where I pioneered calcium imaging applications in hippocampus (Blair et al. eLife 2023; Guo, Blair et al. Sci. Adv. 2023) and anterior cingulate cortex (Hart, Blair et al. JNeuro. 2020) of freely behaving rats to study learning, memory, and decision-making.

During postdoctoral research, I study how the hippocampus and cingulate cortex collectively represent task-relevant information by recording from both regions during spatial navigation tasks. Current research is supported by my NIH F32 NRSA fellowship. Outside the lab, I enjoy cooking with my wife, exploring New York on walks with our dog, video games, hip-hop, and sci-fi.
