Hi, I'm Viv.

I'm currently at LangChain where I lead Applied Research with our Labs team, focused on continual learning, harness engineering, and mining & curating data to build better agents. Before this: a startup building agents for visual reasoning, computer vision & health AI at AWS, and a PhD at Temple University in representation learning. More about me .
