Fellowships from the American Institutes of Indian and Pakistan Studies (2011 and 2012), the American Council of Learned Societies (2015 and 2021), and the Institute for Historical Studies at University of Texas at Austin (2016) have funded her research. Her publications have appeared in Public Culture, South Asia, Bioscope, The Journal of Urdu Studies, SAGAR, and The Caravan and Scroll, among others. At Columbia, Huacuja Alonso teaches courses on South Asian history from an interdisciplinary perspective and on sound studies and media history in addition to Contemporary Civilization in the core curriculum.
Second sound is known as the thermal transport regime where heat is carried by temperature waves. Its experimental observation was previously restricted to a small number of materials, usually in rather narrow temperature windows. We show that it is possible to overcome these limitations by driving the system with a rapidly varying temperature field. High-frequency second sound is demonstrated in bulk natural Ge between 7 K and room temperature by studying the phase lag of the thermal response under a harmonic high-frequency external thermal excitation and addressing the relaxation time and the propagation velocity of the heat waves. These results provide a route to investigate the potential of wave-like heat transport in almost any material, opening opportunities to control heat through its oscillatory nature.

Radio for the Millions (Columbia University Press, 2023) examines the history of Hindi-Urdu radio during the height of its popularity from the 1930s to the 1980s, showing how it created transnational communities of listeners. Isabel Huacuja Alonso traces how people engaged with radio across news, music, and drama broadcasts, arguing for a more expansive definition of what it means to listen. She develops the concept of "radio responses" to understand how radio relied on circuits of oral communication such as rumor and gossip and to account for the affective bonds this "talk" created.

As a group, let us make new inquiries about sound and the senses while drawing attention to histories and stories about underrepresented communities from a wide range of historical periods across culture as well as to forms, ideas, and practices that are centered on sound originated from non-Western contexts. 152ee80cbc
