Marina Dubova
I am an Omidyar postdoctoral fellow at the Santa Fe Institute. My research aims to reveal and inform the cognitive mechanisms of discovery. I develop formal (e.g., computational models) and empirical methods (e.g., cognitive experiments with scientists) to put the foundations of scientific method to rigorous tests. I use insights from cognitive science to learn how theories and data can be integrated and lead to better understandings of the world. My dissertation at Indiana University focused on the cognitive mechanisms of discovery (see précis here). Some questions that I am currently focusing on:
How to best design a scientific experiment? When collecting new data, should we attempt to confirm our theories, falsify them, resolve theoretical disagreements, or sample the data in a way that is not primarily informed by theory? spoiler from my work: against common intuition, more exploratory experimentation might help scientists develop more accurate & useful theories than the theory-informed experiments.
Which theory-building strategies facilitate scientific progress? Should we prefer theories that are simple? spoiler from my work: maybe not! developing theories with a complexity, instead of a simplicity bias might have some unanticipated benefits.
How can we develop better conceptual systems for sciences? What epistemic functions do scientific ontologies play? spoiler from my work: scientific concepts are perspectives that affect all aspects of the scientific work—from data collection, to interpretation and communication. Improving scientific concepts is not possible without taking into account the ways in which these concepts have affected the rest of the scientific process.
Apart from these (already way too broad) issues, I am also studying concept learning in humans and AI, mechanisms of language evolution, and conceptual influences on perception.
I combine behavioral experiments, computational modeling, and theoretical analyses in my research. I work at the intersection of cognitive science, philosophy of science, complex systems, and artificial intelligence.
When I am not learning or studying learning, I like to play music, sing, travel, conduct clay & glazing studies, work on my bird categorization skills, and sail away from and back to the marinas without sinking.
I am always enthusiastic to discuss your/my research and ideas. Please, feel free to contact me :)
