Lead the science behind Plexus products and the education that brings it to life. The Director, Research owns clinical research, scientific substantiation, publications, external research partnerships, and product training. This leader turns product and claim priorities into a practical research roadmap, designs and delivers human studies, and ensures Plexus can clearly explain the evidence supporting its products.
