About Me
My name is Chenghao Lyu. I am also a fifth-year Ph.D. student candidate in the College of Information and Computer Sciences at University of Massachusetts, Amherst, and I am part of the DREAM Lab. I am advised by Prof. Yanlei Diao, and co-advised by Prof. Prashant Shenoy.
Before joining UMass Amherst, I got my BS in EE and MS in CS from Fudan University, where I was advised by Prof. X. Sean Wang.
I worked as a scientific collaborator in CEDAR11 team at Ecole Polytechnique in France for 2.5 years during my PhD.
My research lies in the intersection of big data analytics systems, machine learning, and multi-objective optimization, with a focus on designing optimizers to auto-configure parameters for large-scale systems to achieve improved performance and cost reduction.
I am actively seeking a full-time job in the industrial market in 2024/2025.Email: {first-name}@cs.umass.edu
