Richard earned a B.S. degree in mechanical engineering from Montana Tech in 2014 and a Ph.D. in materials science from Montana Tech in 2018.

From 2000 to 2007, Richard worked for Madison Paper Company where he started as a papermaker and worked his way up to process control. Working in process control, he was responsible for quality of the paper produced at the mill. While pursuing his bachelor’s Richard participated in the summer undergraduate research fellowship (SURF) program at Montana Tech and was an intern at Resodyn.   

After finishing his doctoral work at Montana Tech, Richard was an AIM fellow at Freeport McMoRan where he worked on advanced flotation simulations for PTFI Grasberg. Following the fellowship, Richard worked as a post-doctoral researcher and adjunct faculty at Montana Tech. He performs research as part of four groups: ASSL, CAMP, the Flotation group, and RTR. These groups cover a wide range of mechanical and materials engineering disciplines with Richard’s focus on process design and optimization. Richard was hired in 2021 as an Assistant Professor of Mechanical Engineering. He teaches a wide range of courses related to fundamentals of processing and thermodynamics.

Dr. LaDouceur is the faculty advisor for the Society for the Advancement of Material and Process Engineering (SAMPE) student club and the Associated Students of Montana Tech (ASMT).
