Zvi Biener works primarily on early-modern conceptions of the unity of science and the large-scale structure of fields of knowledge. In particular, he is interested in how early-modern conceptions the unity of knowledge were used to justify the authority of philosophy over the physical sciences. This research consists of three overlapping areas: early-modern views regarding the reduction and dependence of branches of knowledge to/on one another, forms of demonstration and deduction in the new early-modern sciences, and the metaphysical underpinnings of those sciences. When not an academic, he works on web-related projects or codes, compiles, and generally makes a mess with programming languages. His computer concerns mirror his academic concerns: he likes thinking about how knowledge is organized in the computer age, and spends way too much time exploring database and information management technologies.
