No. Unless you are commuting from an area with limited public transportation, we do not recommend using or renting a car to attend the courses. Boston street signage can be very difficult to navigate, parking fees are expensive, and multiple public transportation options are available.
MBTA Subway “T” – The Green Line, Branch D, runs between Riverside (in Newton) and Government Center (in downtown Boston). The Longwood stop is a 15 minute walk from HSPH. The Green Line, Branch E, runs between Heath Street (Mission Hill/Jamaica Plain) and Lechmere (E. Cambridge). The Brigham Circle stop is across the street from the Huntington Avenue entrance of the Harvard T.H. Chan School of Public Health.
MBTA Bus – The MBTA also offers an extensive bus system, which has stops all around the Longwood Medical Area, Mission Hill, and the rest of the Boston area. Be sure to check out the MBTA Trip Planner to find the best route to HSPH and around town for you.
Car – Unfortunately, Harvard does not offer parking options for those who wish to drive to attend the courses. We recommend that participants take advantage of the public transportation and ride share options whenever possible as parking can be expensive in the city.
Parking – If you are driving and will need a place to park, look at public parking garages in the area. Please check the rates in advance to determine what you are comfortable paying. Parking garages near by include, but are not limited to:
Simmons University Parking Garage (10 Min Walk)
333 Longwood Ave Garage (10 Min Walk)
375 Longwood Ave Garage (12 Min Walk) – Is slightly cheaper
Ride Share Options – Uber and Lyft are two very popular and easy methods of ride share transportations in the city. These services are accessible through their mobile applications which you can download for free. Taxis can now also be called through the Uber app.
Our History
In 2017, Miguel Hernán, Judith Lok, James Robins, Eric Tchetgen Tchetgen and Tyler VanderWeele set off to create a public, introductory course on causal inference at Harvard University. This course is still offered today under the name “Key Topics in Causal Inference.”
In 2021, CAUSALab was founded under the direction of Miguel Hernán with a core mission of providing training on causal inference to the next generation of investigators.
Building upon this foundation, 2022 saw the introduction of the Target Trial Emulation course, accompanied by the official establishment of the CAUSALab Summer Courses on Causal Inference.
In 2023, four courses were offered over two weeks for individuals to attend in person or virtually for the first time. A total of 445 participants attended representing over 30 countries and 60+ different organizations that spanned across academia and industry. Additionally, 43 tuition waivers were awarded to 28 students.
The 2024 summer courses cohort included 381 participants from 35+ countries and 150+ organizations. 42 fee waivers were awarded across all four course offerings. The 2025 courses welcomed 400+ attendees representing 200+ organizations, 38 countries, and 35 U.S. states.
