Katherine (Kat) Houghton, Ph.D

Co-Founder & Chief Clinical Officer

Kat started ilumivu in 2009 with Mark to support families struggling with autism and look beyond behavioral interventions to discover what other tools could be helpful. Her work with wearable sensors and mobile tacking led to the development of the ilumivu platform to increase the wellbeing of children with autism. Specializing in parent-implemented approaches, there was a desire to empower parents to take the lead in their child’s development and make evidence-based interventions available to those with fewer resources. Her behavioral interventions are still used in Argentina and Poland.

Today, ilumivu has grown into the leading solution for ambulatory data capture and insight in the clinical research market under Kat’s leadership. To date, over 70 health systems and research universities have completed hundreds of different studies using the ilumivu platform. Kat continues to work individually with adults and leads soul-tending retreats and wilderness rites of passage in the Southern Appalachian Mountains.
