Lori Severino, Ed.D. is a retired Assistant Professor at the School of Education at Drexel University. She teaches courses in reading, high incidence disabilities, and student teaching. Her area of expertise is in reading disabilities. Prior to teaching at Drexel, she was a special education teacher in public education for 26 years. Most of her teaching career was working with students with dyslexia. She is committed to preparing all teachers to be able to teach all students to read. She is a member of the instructional strategies committee of the Philadelphia Readby4th campaign.

Dr. Severino is a certified Wilson Language trainer and teaches the Wilson coursework as well as offering professional development to local districts. Dr. Severino worked with a team of researchers to develop a web-based reading comprehension assessment for adolescents (ACE: Adolescent Comprehension Evaluation). This assessment uses fNIRS (functional near infrared spectroscopy) during the validation process and is a patent-pending process. She is the Co-author of Using Creativity to Address Dyslexia, Dysgraphia and Dyscalculia: Assessments and Techniques. Dr. Severino has presented nationally and internationally at IDA, CLD, and EECERA.
