Associate Professor

LHD obtained his PhD in physics in from Université Laval in Québec. He then branched out in different avenues of complex systems modeling; first in microbial and forest ecology as a James S. McDonnell Foundation Fellow at the Santa Fe Institute, and later as a researcher at the Institute for Disease Modeling. Now at the Vermont Complex Systems Center, he co-leads the modeling arm of the Joint Lab whose research focuses on the interaction and coevolution of structure and dynamics. Recent examples include social networks interacting with the spread of diseases and ideas, the interplay of plant-pollinator dynamics with commercial honeybee colonies and sustainable agriculture, emergence and growth of institutions against societal issues, online interactions between hate and counter speech, or the modeling of learning mechanisms in multidisciplinary team work.
