[9] Markin's interest in laboratory automation, blending clinical processes with information technology, began during his graduate studies, which focused on graph theory.

He didn't design the instruments, but sought an automated system to manage the testing processes, leading to increased efficiency, improved reporting and lower laboratory costs.

LAB-InterLink sold automation systems in North America and internationally, and offices were set up in the United States, Canada and Israel.

He has also received the Lifetime Achievement Award from UNeMed Corporation, UNMC's technology transfer office, for his innovations that have transformed the clinical laboratory.

[11] Additionally, the project has potential uses for other applications, including bioterrorism testing,[12] and holds significant promise for the civilian sector.
