Igor holds the role of a research scientist at CIWRO, where his primary focus lies in the exploration and advancement of innovative signal-processing methods tailored for weather radar applications. Notably, his work has led to the successful implementation of two cutting-edge techniques within the operational framework of the WSR-88D network of weather radars.

Another significant facet of Igor's research centers around the polarimetric phased array radar (PPAR). In this domain, his investigations revolve around the development of strategies to address cross-coupling effects and the calibration of PPAR systems. Notably, Igor spearheads the efforts related to the calibration of the Advanced Technology Demonstrator (ATD) within this field.
