MTA Veterans Ronnie Hakim and Sally Librera Join Transit Tech Lab as Executives-in-Residence

2 min readNov 9, 2022

Last week, the Transit Tech Lab announced two Executives-in-Residence who will provide strategic advice to Lab participants.

Ronnie Hakim, HNTB’s national transit and rail market sector leader, and Sally Librera, AECOM’s transit market leader for the Americas, both served in leadership positions at the MTA — North America’s largest transportation network — and have a combined 50 years of experience in public transit operations and policy.

Through this initiative, Lab participants will gain insights on the requirements and operational issues at major public transit agencies. This personalized consultation will ensure that companies’ solutions provide value and address the needs of agencies and riders.

Ronnie and Sally recently joined the Lab to work with the companies selected for the Recovery and Sustainability Challenge pilots. Six companies are deploying technologies to address public transit safety, track new mobility patterns, and support clean energy goals for the MTA, Port Authority of New York and New Jersey, and NJ Transit.

Please join us in welcoming Ronnie and Sally to the Lab family and stay tuned for next year’s challenge announcement!
