Brian Hentschel

I am a Ph.D. candidate at Harvard University advised by Stratos Idreos.

My research focuses on the intersection between data systems and machine learning. During my Ph.D., my work has focused on how learning contextual properties of the workload, i.e. expected data and operations, can be used to create new designs that bring significant improvements on fundamental problems in data structures. Additional works outside my Ph.D. thesis focus on the opposite direction, trying to build systems which make it easier to get insight from data.

Before my Ph.D., I received my undergraduate degree from Pomona College with concentrations in mathematics and computer science. I additionally have spent time in industry as both a researcher and software developer, spending time at Microsoft Research, IBM Research, LinkedIn, and Amazon.

Please see my resume for more details.
