Alexander Spangher
Postdoctoral Scholar, Computer Science
BioAlexander Spangher is a post-doctoral researcher advised by Daniel Ho, Sanmi Koyejo and Diyi Yang. His research focuses on modeling human decision-making in creative domains, especially in contexts where data is limited and rewards and goals are less clear. He is building out a new domain of learning, called emulation learning, with the goal of training the next generation of reasoning-oriented language models to be more proficient in these domains. His research has been used at technology organizations like OpenAI, Google and EleutherAI. He is especially passionate about helping journalists and has framed tasks and trained reasoning LLMs to help journalists find stories and sources, structure narratives and track information updates. These tools have been incorporated into newsrooms at the New York Times, Bloomberg and Stanford Big Local News, impacting thousands of journalists; and his work is also informing the next generation of journalistic education at USC Annenberg. His work has received numerous awards including two outstanding paper awards at EMNLP 2024, one spotlight award at ICML 2024, one outstanding paper award at NAACL 2022 and a best paper award at CJ2023; and he has been supported by a 4-year Bloomberg PhD Fellowship. His work is broad: in addition to his work in NLP and computational journalism, he has studied misinformation at Microsoft Research and collaborated with the MIT Plasma Science and Fusion Center to model plasma fusion processes.

Catherine Spurin
Postdoctoral Scholar, Energy Resources Engineering
BioI am a postdoctoral researcher in the Energy Science & Engineering department. My current research is focused on understanding how subsurface heterogeneity can be exploited to increase the amount of CO2 that is residually trapped. This increases storage security and minimizes the spread of the CO2 plume. This research makes up part of the GeoCquest consortium with Melbourne University, Cambridge University and CO2CRC. My supervisors are Prof. Hamdi Tchelepi and Prof. Sally Benson.
I obtained my PhD from Imperial College London in 2021. My PhD thesis "Intermittent flow pathways for multiphase flow in porous media: a pore-scale perspective" explored how flow phenomena not included in the framework of Darcy's law extended to multiphase flow influence the propagation and trapping of fluids. My supervisors were Prof. Sam Krevor and Prof. Martin Blunt. My research was funded by the President's PhD scholarship at Imperial. -
Griffin Srednick
Postdoctoral Scholar, Oceans
BioGriffin Srednick, PhD, is an NSF Postdoctoral Research Fellow at Stanford Oceans and a community ecologist specializing in the spatiotemporal dynamics of marine communities. His postdoctoral research investigates how coral reef communities recover from disturbance and respond to the effects of climate change. Conducted within the National Science Foundation's Moorea Coral Reef (MCR) Long Term Ecological Research (LTER) program, his work examines how spatiotemporal heterogeneity in coral communities can promote ecological resilience. By integrating oceanographic modeling with coral reef ecology, his research aims to reveal the mechanisms underpinning coral recovery following disturbance. His broader scientific interests focus on understanding the complex architecture of ecosystems and how a holistic view of ecological systems can inform and enhance conservation and restoration strategies.

Sriram Sudarsanam
Postdoctoral Scholar, Neurosurgery
BioSriram is broadly interested in how cellular interactions shape neurodevelopment. He completed his undergraduate studies at the Indian Institute of Science, and Masters at the Weizmann Institute. His doctoral research in Alex Kolodkin’s laboratory at Johns Hopkins addressed the development of idiosyncratic axonal arborization patterns of cortical neurons. He developed genetic strategies to visualize and perturb sparse populations of neurons in the mouse brain, using which he identified novel molecular and cellular determinants of spatially-restricted axon branching in vivo.
Now, as a postdoctoral scholar in Brad Zuchero's laboratory, Sriram is working to develop novel genetic tools to observe and perturb neuron-oligodendrocyte interactions in vivo. In collaboration with Ivan Soltesz’s laboratory, he aims to employ these tools to understand how myelination regulates neural circuit assembly and function. -
