Worrying over Speaking and the Pretentiousness of Podcasts

Read the transcript here. This was meant to be a podcast about making podcasts. But in the end, this podcast is really just a conversation between two people who used to be close friends. It rambles and meanders. It doesn’t always stick to a coherent point. I wondered then whether it could also be academically useful. Relevant to conversations in anthropology? Or even interesting to anyone other than me? This podcast is a conversation with Thuy Nguyen, founder of the Berkeley Community Acupuncture clinic and licensed TCM practitioner who has her own podcast, You Are Medicine. We first started talking about what it’s like for her to make a podcast back in March, on a long drive together from Bakersfield, California to Window Rock, Arizona. Thuy runs acupuncture pop-up clinics and is training interns as part of her Navajo Healing Project there and she invited me to spend a weekend (read more...)

Space Anthropology with Savannah Mandel

View/Download the transcription for this episode. For this episode of Platypod, I interviewed space anthropologist Savannah Mandel about her new book Ground Control: An Argument for the End of Human Space Exploration (Chicago Review Press, 2024) where she writes about commercial space exploration in the US based on her ethnographic fieldwork with SpacePort America in New Mexico, and with space policymakers in Washington DC.  (read more...)

The Many Modes of Ethnography

Download the transcript for this episode. This podcast episode talks to three anthropologists, Rachel Douglas-Jones, Rine Vieth, and Kara White, scholars working in three different parts of the world who use multimodal methods in their teaching and research. It is not a history of multimodal methods, or even a really detailed review of them; instead, it is a consideration of some of the issues they raise or resolve for ethnography. Whatever Tim Ingold has or hasn’t said about ethnography, he inadvertently offered what I think is the most compelling definition when he wrote: It is where we, “join with things in their passage through time, going along together with them, working with them, and suffering with them” (24, 2020). I’m tweaking the first part of this sentence to make it work here, as he’s actually describing the Latin prefix co- and his idea of “the gathering,” but it works for (read more...)

Platypod, Episode Eight: CASPR 2023

Download the full transcript of this episode. The 2023 edition of CASPR: CASTAC in the Spring discussed digital ethnography and its multiple facets. The event was moderated by Dr. Baird Campbell, who, along with guest speakers Dr. Ilana Gershon, Dr. Nicole Taylor, and Dr. Patricia G. Lange, shared their experiences and valuable insights based on their many years of interactions with digital ethnography—much before the recent spike in interest in this method due to the COVID-19 pandemic. Some critical insights from the event: On the online-offline divide, guest-speakers pointed out that this division will not matter in the future as interlocutors are increasingly interconnected. Speakers were skeptical about how much this topic still matters now, coming to the conclusion that this separation is largely artificial. The speakers mentioned how digital technologies, social media platforms, and other technological products would indirectly be part of future ethnographies, even if the researcher had (read more...)

Platypod, Episode Seven: An Anthropology of Data, AI, and Much More

Download the transcript of this interview. For this episode of Platypod, I talked to Dr. Tanja Ahlin about her research, work, and academic trajectory. She’s currently a postdoctoral researcher at the University of Amsterdam in the Netherlands, and her work focuses on intersections of medical anthropology, social robots, and artificial intelligence. I told her of my perspective as a grad student, making plans and deciding what routes to take to be successful in my field. Dr. Ahlin was very generous in sharing her stories and experiences, which I’m sure are helpful to other grad students as well. Enjoy this episode, and contact us if you have questions, thoughts, or suggestions for other episodes.  (read more...)

Introducing Citizen Technology: Ethnographic Insights from Makerspaces

When I first arrived at the makerspace known as Fab Casa del Mig, in the Sants neighborhood of Barcelona, I crossed a large urban park called La España Industrial. I later learned that the park occupies the site of a former textile factory with the same name. Walking through the park, I passed people walking their dogs, groups playing basketball or pétanque, and others simply spending time with their family there. At the end of the park stands Fab Casa del Mig, the last remaining building of this former industrial complex. Inside, there is a large makerspace. (read more...)

Becoming Experts: Activists Working Against Science Based on Misinformation

In County Donegal, Ireland, an estimated 30,000 buildings are crumbling due to governmental and commercial mishandling of building materials such as concrete. A lack of urgency in governmental response has left homeowners living with severe mold, electrical risks, structural cracks and the impending threat of their homes collapsing, see image below. Homeowners have described living in these homes as being in a constant state of fear—fear their homes will crumble on top of them but also fear that the government they once trusted “to do right by them” will never fix their homes.

“Tech-ing” the “Justice Gap” and/or (Re)imagining Access to Justice in Africa

“What would we say if a health system did not cure 60 to 70 per cent of health problems properly? And I can tell you more, this gigantic justice gap affects more people in the world than some of the big diseases we all know and read about – malaria, HIV, and tuberculosis!” a speaker exclaimed at an international conference called “Tech the Justice Gap” in 2020. Drawing a comparison between healthcare and access to justice, he continued, “5.1 billion unmet justice needs,” emphasizing that the lack of access to justice requires greater international attention.

Salt: A Provocation

Salt. That everyday thing we use to season our meals, relax our muscles, or make our icy roadways safer to traverse. Salt is an inescapable part of human experience, and yet, as anthropologists, it often escapes our attention. In recent years, anthropologists have turned their attention to what Cymene Howe (2026) calls the ‘elemental’, referring to the objects and processes – often simultaneously both – that constitute the world. Ongoing environmental crisis means coming to experience the elemental in new ways, both within and around the body. Salt, or sodium chloride, is one of these elements. (read more...)

Seeing, Acting, Believing: The CyberKnife and the Transformation of Medical Imaging

Dr. Sinha is the anti-Benjamin of our times. He asks his patients to believe in the aura of the machine. When I meet him in the treatment room at the corner of the Radiation Oncology wing on a Thursday afternoon—its ceiling painted blue with drifting, improbable clouds—he speaks in paragraphs, waxing lyrical about the CyberKnife’s precision. The CyberKnife’s industrial robotic arm, he tells me, is a direct import from the automobile assembly line. At his cue, the technologists in the control room set it in motion. The arm whirrs as it moves along three linear and rotational axes; it is designed to track the movements of the patient’s body in real time. Dr. Sinha walks me through each piece of the ensemble: the ceiling-mounted x-ray machines that track the tumour’s position, the large linear accelerator that charges the radiation beam, a phantom skull laid on the table for setting delivery coordinates. “High dose and minimal margins,” he insists, “is the future of radiation therapy.” (read more...)

Microbes and the Permeable Body: Rethinking Health Through the Holobiont

Donna Haraway opens When Species Meet with the proclamation that “human genomes can be found in only about 10 percent of all the cells that occupy the mundane space I call my body” (Haraway, 2007). The rest of the human body is comprised of bacteria, viruses, archaea and other microorganisms – largely invisible to the human eye, but nonetheless living on and within us. In recent years we have seen a proliferation of research and attention towards these microorganisms, particularly in the gut, skin, lungs, and mouth, with each comprising their own microbiome. Although this research is still developing, it is increasingly clear that these microorganisms may actually be fundamental to the development and functioning of human bodies. (read more...)

Animals in War: Multispecies Agency and the Memory of the Colombian Armed Conflict

In one testimony from Colombia’s armed conflict, a parrot named Lola repeated the phrases she heard around her: “Paraco asesino” (“paramilitary murderer”), “Viva la guerrilla” (“long live the guerrilla”), and “The vultures are coming” Her voice condensed the sounds, fears, and political tensions of war into a multispecies archive of memory. Far from being passive witnesses, animals moved within the infrastructures of conflict as companions, alarms, transportation, and sometimes even weapons. Yet these violent incorporations are only the most extreme expression of a broader multispecies world of conflict. (read more...)

On both sides of the large entrance to the building, posters for art exhibits are prominently featured.

Making for the Feed: Creativity, Platforms, and Visibility in China

Creativity is often imagined as a deeply human capacity: a moment of inspiration, a flash of originality, or an individual act of expression. Yet in contemporary digital environments, creativity rarely unfolds in isolation from technological systems. Across creative industries, from fashion and design to visual media, branding, and online content production, creative work increasingly takes shape within infrastructures of platforms, software tools, and algorithmic systems. These technologies do not simply enable creativity; they actively shape how creative ideas are imagined, produced, circulated, and evaluated. (read more...)

What Would Happen if Ethnographers Learned to Process Signals?

During my doctoral research, focused on neuroscience laboratories and their forms of engagement with other spaces in the city of Bogotá, Colombia, I have been observing how artists and researchers use different processes to modulate, transform, and process biological signals in order to create artistic works. This experience led me to try to learn how to use the same software they employ. I created a small piece that I would like to show, along with a brief presentation of some of the reflections that emerged from it. (read more...)

Blood Circulation: Opening Up a Closed System

On any given day, at any given moment, blood flows through bodies, flesh and viscera, shaping our world from the inside out. The process is rather simple, I have been told: in the human body, blood is propelled by the heart, repetitively flowing from the right atrium and right ventricle, through the pulmonary system, into the left atrium, left ventricle, and aorta. It then unfurls into the rest of the body and back to our starting point, the right heart. (read more...)

What’s in a Name?

“My Dear Sir,” wrote Henry Fox Talbot one Wednesday in late 1870, “I am informed by Mr. Cooper that a new Society under your auspices is going to be…formed for the promotion of Egyptian and Assyrian Archæology and Biblical Chronology…It will perhaps be difficult to devise a suitable name for the Society, that of Syro-Egyptian being preoccupied. Perhaps Egypto-Chaldæan would do – I know nothing of the Syro-Egyptian beyond its name, but I suppose from the fact of your promoting a new society, that you think the Syro-Egyptian a failure.” Talbot was a British aristocrat and a scholar of Assyrian cuneiform, writing to Dr. Samuel Birch, keeper of Oriental Antiquities at the British Museum. The two men had corresponded about Assyrian antiquity for almost twenty years, working to decipher cuneiform texts stamped into ancient clay tablets. Birch’s response was swift. His new project would combine the Syro-Egyptian Society with another organization, the Chronological Institute, to create an expanded journal for “researches connected with Biblical lands.” (read more...)

What the Map Conceals: Sovereignty and the Sea in the Strait of Gibraltar

An aerial view of the Strait of Gibraltar shows something that resembles order. Container ships move in two disciplined lanes, their wakes parallel lines across the surface. Between them, a single patrol vessel sits like a traffic cop at an intersection. Smaller ships move differently: ferries on fixed schedules, fishing boats angling across the grain, following lines invisible from above. The Strait, fourteen kilometers at its narrowest, appears split down the middle, dividing Morocco from Spain, Africa from Europe. Deleuze and Guattari (1987) described the sea as the exemplary smooth space—fluid, directionless, resistant to the grid—but also as the first place to be striated, ruled into navigable geometry by technologies of longitude and open-water navigation. From above, the striae of the strait are clear. The question is what that striation conceals. (read more...)

A screenshot of an official, public notification from the Gazette of India announcing the enforcement date of the Surrogacy (Regulation) Act, 2021. The text is in English and Hindi, and describes the source of the notification (Ministry of Health and Family Welfare, Department of Health Research, Government of India), and states that the provisions of the Act will come into force on January 25, 2022.

Criminality, Risk, and Labor: Altruistic Surrogacy in Contemporary India

Surrogacy is a form of assisted reproduction in which the gestational labor of birthing a child is carried out by someone other than the intending parent/s. Surrogacy in India has gained a great deal of popularity over the last three decades, emerging as a major transnational commercial hub. Generating close to $2.3 billion in annual revenue (Rudrappa 2015), the industry was largely unregulated, until recently. In December 2021, the Indian state passed the Surrogacy (Regulation) Act, criminalizing commercial surrogacy and permitting only altruistic surrogacy for select clients. The Act bans the “commercialization of surrogacy services,” outlawing any possible compensation for surrogate workers, whether it is “payment, reward, benefit, fees, remuneration, or monetary incentive in cash or kind” (Government of India 2021, 2). In effect, surrogacy is legally permitted only if it is “altruistic,” with heavy punitive measures in place for commercial surrogacy. By “altruistic” surrogacy, the state means an unpaid surrogacy arrangement that is borne out of the good will and selflessness of the surrogate worker, upon whose body the biomedically intensive, complicated, and risky process of surrogacy is carried out. It is important to note that surrogacy arrangements in India are largely shaped by stark power imbalances. Surrogate workers tend to come from marginalized socioeconomic backgrounds, and are often low-income, oppressed-caste women from rural areas. Intending parent/s, by contrast, are typically more privileged – urban, middle-to-upper-class, and from dominant-caste groups. These structural disparities have significant implications for surrogate workers in the current moment, with the regulatory turn to “altruism.” (read more...)

Data Borders: Three Years Later

What should we do today? How would you write Data Borders differently today? But what can I do? People often ask me these questions when I present my research on my book, Data Borders: How Silicon Valley is Building an Industry Around Immigrants (Villa-Nicholas 2023), which examines the growing industry of data collection for the surveillance and control of immigrants in the United States. These questions arise in undergraduate and graduate classrooms, at academic conferences, and among public workers in the United States. I respond by advocating for policy protections for immigrant information rights, providing examples of data rights activism, and demonstrating how we are applying techno-imagined futures within my Southern California community to advocate for humane shifts in technological design and data collection.

Gender Dimensions of Platform Work: How Do They Shape Unionizing?

This article is the fourth article in a series about gig and platform worker unions in India written by members of the Labor Tech Research Network. Read the introduction to the series here, the second post in the series here, and the third post here. In January 2024, hundreds of women workers associated with the on-demand home services app Urban Company (henceforth UC) gathered in protest outside the platform’s regional office in Hyderabad, India. The workers, many of whom were working as beauticians on the app, were protesting a slew of platform policies that had steadily eroded their working conditions over time (Figure 1). Most notable of these was the introduction of a new feature called ‘auto-assign’, which requires workers to mark the time slots that they are available to work on the app, following which they are assigned gigs automatically by the platform. The new ‘auto-assign’ policy marked a significant shift away from a previously more flexible system, where women could choose their gigs and hours. The promise of flexibility has been a prime reason that attracted women workers to platforms like UC, as it enables them to access paid work while also attending to their housework and care work responsibilities. It is this very erosion of flexibility that women were holding UC to account for. (read more...)
