Φ-Geo is a research group dedicated to exploring topics in the philosophy of the geosciences (historical and current Earth sciences), broadly understood. Areas of research pursued by Phi-Geo members include epistemological, methodological, and metaphysical issues in geochronology, paleontology, paleobiology, ecology, geomorphology, climate & paleoclimate studies, and especially issues related to philosophy of modeling and data. Below you will find group member bios, recent publications, and news.
Director of Research Group:
Dr. Alisa Bokulich
Alisa is currently writing a new book Philosophy of the Geosciences: Data, Models, & Uncertainty, which draws on conceptual and methodological issues in geomorphology, stratigraphy, paleontology, and geochronology, with chapters on issues related to models, data, uncertainty, typification, and the philosophy of geologic time. For further details see her bio and research pages. (She pronounces her name ‘uh-LEE-suh’ ‘BEAU-coo-litch’)
Graduate Student Members
Federica’s PhilPeople Profile
Federica’s research mostly focuses on metaphysical issues in philosophy and in the history of the life sciences. She is particularly interested in exposing the conceptual and metaphysical assumptions embedded in scientific methods and practices. Her interests range from biological essentialism to causation and identity in eco-evo-devo and microbiology. Recently, she has been working on how scientific uncertainty affects ecology and biodiversity estimates, including paleoecology and paleodiversity. (She pronounces her name ‘Feh-deh-REE-kah’ ‘BOKE-key’.)
Leticia Castillo Brache
Leticia is interested in philosophy of science specifically issues regarding measurement in science and climate science. She is currently working on epistemological issues in paleoclimate proxies. She is also interested in philosophy of biology particularly in animal consciousness and conservation biology. Some of her other interests are in feminist philosophy and Latin American philosophy, especially issues regarding identity. (She pronounces her name ‘Luh-TEE-see-ah’ ‘Cas-TEE-yo’ ‘Bruh-CHeh’.)
Aja’s Google Scholar Profile
Aja is primarily interested in epistemological issues in the historical sciences, such as paleontology and paleoclimatology, as well as related topics in philosophy of biology and philosophy of the earth sciences more broadly. In particular, she is interested in how we can use the paleoclimate as an analogue model for contemporary climate change. Aja’s other recent work touches on the topics of developmental biology, microbiology, and feminist philosophy of science. (She pronounces her first name ‘ASIA’.)
Gloria is a senior majoring in Philosophy and Political Science. She is interested in the philosophy of science, environmental issues, and how past mass extinctions can inform us about endangered species today. Her other research has been focused on political philosophy, where she examines topics such as civil disobedience and theories of utopia. She is also interested in Africana philosophy and Feminist philosophy that specifically explores the existential significance of race and gender. She has received a UROP grant this year to pursue her research project on “Are We in a 6th Mass Extinction? What Past Mass Extinctions Can Teach Us”. (She pronounces her last name ‘Grahn-Pea-Air’.)
Henry is a current senior from Singapore majoring in Advertising from the College of Communication. Henry is interested in the philosophy of paleontology, especially with issues of underdetermination in the fossil record, interpretations of unique structures of extinct lifeforms, and the evolution of first life. His passion stems from paleontology, and he created and has managed the Eons Ago Instagram account for over four years to showcase his extensive fossil collection. His recent work includes an interpretation for trilobite anterior cephalic projections through analogous modern arthropods.

Φ-Geo Group News
- Congratulations to Henry, whose awesome dinosaur discovery is a featured story in BU Today!
- Leticia & Aja will be presenting their work in progress on
“Proxy Data: The Epistemic Advantages of Indirect Measurements”
at the international graduate student group Idee in Bozza at the Università degli Studi di Parma
Nov. 18th 12:00 Boston time (18:00 CET).
- Congratulations to our undergrad member Gloria on receiving a $1,300 Student Research Award to pursue her project “Are We in a 6th Mass Extinction? What Past Mass Extinctions Can Teach Us”!
- Our graduate students Federica and Aja have been accepted to the week-long interdisciplinary Summer School on Quantitative Palaeontology, organized by Professor Indrė Žliobaitė (U of Helsinki). They are very much looking forward to exploring issues at the intersection of paleontology, fossil data, philosophy of science, and data science.
- We are thrilled to announce that Aja has received one of the highly competitive 2020 National Science Foundation NSF Graduate Research Fellowships, which will support her graduate studies over the next 3-5 years.
- Alisa’s PSA Symposium session on “Reconstructing Geologic Time” has been accepted for PSA 2021, Nov. 11-14, in Baltimore:
Abstract: The aim of this symposium is to explore some of the key philosophical issues involved in the reconstruction of geologic time. It will address methods for synchronizing the imperfect clocks of geologic time (Katherine Valde, Wofford College), strategies for reconstructing time from the missing stratigraphic record (Alisa Bokulich, BU), conventionality versus naturalness in delimiting the units of geologic time (Joeri Witteveen, University of Copenhagen, Denmark), methodological insights from shallow-time stratigraphy (Carlos Gray Santana, University of Utah), and the high scientific and social costs of failing to recognize the Anthropocene as a formal unit of the GTS (Hernán Bobadilla, University of Vienna, Austria).
