Sam Marsden

Sam grew up in Greenfield, Massachusetts. He stayed in Western Massachusetts to attend UMass Amherst, where he graduated with a B.S. in Chemical Engineering and a certificate in Material Science in the spring of 2021. At UMass he worked in the lab of Dr. Laura Bradley in the Polymer Science and Engineering department where his primary research was on the synthesis of active colloidal particles but with side projects on computation modeling of surface active particle interactions. Upon leaving UMass, Sam moved to Chicago to join the Pritzker School of Molecular Engineering and the Rowan research group in the fall of 2021.

Sam's research is focused on synthesizing new circular polyolefins with the intention of improving chemical recyclability in plastics.
