Marina Dubova
I am a Cognitive Science PhD student at Indiana University. My current research aims to reveal and inform the cognitive mechanisms of discovery. I develop formal (e.g. computational models) and empirical methods to put the foundations of scientific method to rigorous tests and use insights from cognitive science to better understand how theories and data can and should be integrated to come up with understandings of the world. 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 ontologies for sciences? What epistemic functions do scientific ontologies play? spoiler from my work: it is complicated; reengineering of scientific concepts should take into account the ways in which previous concepts might have affected the evidence.
Apart from these (already way too broad) issues, I am also studying language learning in humans and AI, mechanisms of language evolution, and conceptual influences on perception.
I combine theoretical analyses, behavioral experiments, and computational simulations 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 attempt to 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 :)
