Petras Rupšys

Petras Rupšys is a Professor at the Department of Forest Sciences within the Faculty of Forest Sciences and Ecology at Vytautas Magnus University. His academic career spans over four decades, with a focus on applying stochastic differential equations (SDEs) to model biological populations and forest growth dynamics.

• Education: Graduated from Vilnius University in 1975; earned a Ph.D. in Physics and Mathematics in 1982.

Research Interests: Petras Rupšys specializes in mathematical modeling of biological populations, stochastic differential equations, and statistical methods in forestry. His work bridges theoretical mathematics with practical forestry applications, developing nonlinear mixed-effects SDE models to analyze forest stand growth, stem taper, and resource dynamics.

Advising and Projects: He has supervised doctoral and master's theses, including Martynas Narmontas (2023) on SDE-based forest growth models and Rokas Šturma (2016) on stochastic stand volume estimation. His projects emphasize data-driven calibration of SDEs using empirical datasets from Lithuania's forests.
