Since June 2025, Ashton-Rickardt has served as Managing Director and Chief Scientific Officer at BE Therapeutics, a seed-stage biotechnology company developing proto-cortex technology. The company uses iPSC-derived neurons, glia, and vascular cells combined with proprietary extracellular matrix protein biogels to produce proto-cortex implants designed to replace damaged brain tissue and treat stroke, neurodegenerative diseases, and traumatic brain injury. Animal model validation is underway with a development path targeting chronic stroke patients within three years.

Ashton-Rickardt received the Presidential Early Career Award for Scientists and Engineers from President William Clinton in 1999. His research has focused on T cell biology, CAR-Treg platforms, shielded living cell products, myeloid cell reprogramming, and antibody discovery and engineering. He has served on review panels for the Science Foundation of Ireland, Israel Science Foundation, and Medical Research Council, and was a panel member for NIH Study Sections in Immunobiology and Cell & Molecular Immunology B from 1999 to 2006.
