Since most legislation is drafted primarily by professional committee staff, I thought it would be useful to list the following (obtained from various on-line sources, primarily congress.org but there is a Congressional handbook you can buy that has this info)

Republican Staff - House Committee on Transportation and Infrastructure

FULL COMMITTEE, MAIN OFFICE
2163 Rayburn HOB, Washington, DC 20515
202-225-9446
Coon, Jim Chief of Staff
Hines, Clint Staff Assistant
Mullen, Suzanne Newhouse General Counsel
Rosa, Jason Legislative Assistant
Steinmann-Smith, Amy Policy Director

AVIATION SUBCOMMITTEE
The Hon. Thomas E. Petri, Ranking Republican
2251 Rayburn HOB, Washington, DC 20515
202-226-3220
Edwards, Bailey Professional Staff
Lyons, Holly Woodruff Staff Director
Perez, Simone Legislative Staff Assistant

What I've got for the Democratic Staffers is actually more limited in this case:

Majority Communications Director Jim Berard - (202) 225-6260
Majority Press Secretary Mary Kerr - (202) 225-6260
Majority Staff Director David Heymsfeld - (202) 225-4472

and for the Aviation subcommittee Majority Staff Director Giles Giovinazzi - (202) 225-9161

Here is information for Senate professional staffers who may be relevant:

Commerce, Science, and Transportation Committee:

I don't see a listing for professional committee staff for that subcommittee
