Sohaib Ahmad

I am a Research Scientist at Meta working in the Facebook Stories Infrastructure team to improve the efficiency of ML model serving.

I recently completed my Ph.D. at the University of Massachusetts, Amherst working under the supervision of Prof. Ramesh Sitaraman and Prof. Hui Guan. My research interests lie at the intersection of systems and machine learning, particularly improving the resource efficiency of ML inference and model serving. As the demand for ML grows at a much faster rate than the underlying infrastructure to host and serve it, my research aims to improve the efficiency of existing infrastructure to serve this growing demand, through intelligent resource allocation and workload scheduling.

During my Ph.D., I interned at Meta with their Serverless Computing team. I also interned with Bell Labs research twice to work on scheduling and resource allocation for ML model serving and training on the cloud and edge.

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.
