Comparative urban form with a focus on Central and Eastern Europe; comparative urban planning and land-use regulation with a focus on Europe and the United States; and urban planning and design theory and history[2]
Hirt's work attempts to explain why houses in the U.S. are so large relative to other industrialized nations. "People intuitively often think that this is the explanation … because America is such a big country. Well, this is true, but Russia is a big country. Kazakhstan is a big country. Space itself doesn’t really make people do one thing or another."[7] She rebuts President Trump's message to immigrants that "Our country is full", saying "Factually speaking, the country is not actually full — that’s impossible. The real question is, if you continue on the current path of immigration, does this bring more benefits than it brings costs?"[8] She also notes the unusual preponderance of single-family zoning: "I could find no evidence in other countries that this particular form — the detached single-family home — is routinely, as in the United States, considered to be so incompatible with all other types of urbanization as to warrant a legally defined district all its own, a district where all other major land uses and building types are outlawed."[9]
