Simulations Plus has promoted John DiBella to vice president of marketing and sales.
In his new post, DiBella will have signature authority on multiple corporate documents, including software license agreements, confidentiality agreements, and consulting and collaboration contracts, the company said.
Prior to taking on the position, DiBella held several positions at Simulations Plus including director of marketing and sales; manager of marketing and sales; senior applications scientist; and modeling and simulation scientist.
