Neha Karanjkar 




Assistant Professor, Computer Science and Engineering
School of Mathematics and Computer Science
Indian Institute of Technology Goa

Office: Room F10, Lab 2, Acad Block A,
IIT Goa, Farmagudi, Ponda, Goa 403401


I work on parallel simulation, performance modeling and simulation-driven design of discrete-event systems, and build open-source frameworks that put these ideas into practice. My recent work applies lessons from Parallel Discrete-Event Simulation (PDES) to the synchronization of multi-agent (LLM/AI) systems that act concurrently on shared state.

I received my M.Tech and Ph.D. in Electrical Engineering from IIT Bombay, and was a post-doctoral fellow at the Robert Bosch Centre for Cyber-Physical Systems, IISc Bangalore, and a research scientist on the Ajit indigenous processor project at IIT Bombay, before joining IIT Goa in 2019.

Research Interests

  • Multi-agent synchronization: AI agents on shared state, conservative-to-optimistic execution, speculation and rollback

  • Parallel and hybrid simulation: parallel discrete-event simulation, mixed discrete-continuous simulation, simulation-based optimization

  • Computer systems performance modeling: cycle-level models of processors, accelerators and systems-on-chip

  • Simulation for digital twins and supply chains: automated model generation, learning-based surrogates (including graph neural networks), open simulation libraries

See the Research page for projects, code and papers.

Prospective Students

IIT Goa students interested in working with me in these research areas can get in touch via email. Students from outside IIT Goa seeking admission to an M.Tech, M.S. by Research or Ph.D. position should apply directly through the institute's admission process.

Internships: I currently do not have any internship positions available, and I am unable to reply to individual requests. IIT Goa announces a call for prospective interns every year, usually between March and May, listing faculty and project areas. Please apply through that call.
