Sohaib Ahmad

I am a Computer Science Ph.D. student at the University of Massachusetts, Amherst working under the supervision of Prof. Ramesh Sitaraman and Prof. Hui Guan. My research lies at the intersection of systems and machine learning: I use machine learning to improve the performance of computer systems, and use my systems knowledge to improve the performance of machine learning algorithms. I build theoretical models to represent distributed data processing systems, and use the models to improve the performance and efficiency of those systems.

I recently wrapped up an internship at Meta (formerly Facebook) with their Serverless Computing team. Previously, I have been a Research Intern at Bell Labs research twice to work on scheduling and resource allocation for ML inference and training workloads in compute clusters.

Before starting my Ph.D., I completed my undergrad from LUMS in 2017 under the supervision of Prof. Ihsan Ayyub Qazi where my research focused on computer networks and measurement.


  • [Aug 2023] Our paper, “Proteus: A High-Throughput Inference-Serving System with Accuracy Scaling” has been accepted to ASPLOS 2024! (acceptance rate: 16.2%)
  • [May 2023] 🏆 Our paper, AggFirstJoin, won the Best Paper Award at ACM/IEEE CCGrid 2023!
  • [Aug 2022] I wrapped up my internship at Meta (formerly Facebook) with their Serverless Computing team. Over there, I worked on using elastic compute to process asynchronous computing workloads with varying levels of SLA delay requirements.
  • [Dec 2021] I presented our paper, AggNet, at the ACM/IEEE Symposium on Edge Computing! You can find the slides here. I also presented a poster version of the paper at the conference.
