Ehsan Kamalloo

My name is Ehsan (pronounced /eh☀️/ or /ih☀️/, or even /e☀️/). I am a Senior Research Scientist in the Frontier AI Research team at ServiceNow AI Research.

I am broadly interested in building intelligent autonomous systems that are capable of complex reasoning (PipelineRL and TapeAgents). In particular, my work explores how learning and interaction can enable LLM agents to plan over long horizons, adapt to feedback, and operate effectively in multi-agent environments. Previously, my research focused on reliable evaluation (e.g. “LLM-as-a-judge for QA” at ACL’23 and SIGIR’24, and “MIRACL” at TACL’23).

Prior to ServiceNow, I was a Post-doctoral Fellow at the David R. Cheriton School of Computer Science, University of Waterloo, hosted by Jimmy Lin. I completed my PhD at the University of Alberta, advised by Davood Rafiei. I was also fortunate enough to collaborate with Charles Clarke and Siva Reddy. I also interned as a researcher at Huawei Noah’s Ark Lab in Montreal and worked with Mehdi Rezagholizadeh. Before PhD, I was working as a software engineer.
