    Dr. Mark D. Losego is an associate professor in the School of Materials Science and Engineering at Georgia Tech. The Losego research lab focuses on materials processing to develop novel organic-inorganic hybrid materials and interfaces for microelectronics, sustainable energy devices, national security technologies, and advanced textiles.  The Losego Lab combines a unique set of solution and vapor phase processing methods to convert organic polymers into organic-inorganic hybrid materials, including developing the science to scale these processes for manufacturing.  Prof. Losego’s work is primarily experimental, and researchers in his lab gain expertise in the vapor phase processing of materials (atomic layer deposition, physical vapor deposition, vapor phase infiltration, etc.), the design and construction of vacuum equipment, interfacial and surface science, and materials and surface characterization.  Depending on the project, Losego Lab researchers explore a variety of properties ranging from electrical to electrochemical to optical to thermal to sorptive to catalytic and more.

    Prof. Losego received his B.S. degree in materials science and engineering from Penn State University in 2003 (with a focus on electronic and photonic materials), earned an M.S. (2005) and Ph.D. (2008) in materials science and engineering from North Carolina State University (primarily in vapor phase deposition of functional oxide thin films), and completed postdoctoral studies at the University of Illinois (studying chemical surface modifications and nano-scale thermal transport across hybrid interfaces).  Prior to joining the faculty at Georgia Tech, Prof. Losego was a research assistant professor in the Department of Chemical and Biomolecular Engineering at North Carolina State University where he led research efforts in using atomic layer deposition (ALD) to stabilize molecular catalysts for photoelectrochemical energy systems.

    Prof. Losego is also the faculty founder and director of The Materials Innovation and Learning Laboratory (The MILL), an open-access make-and-measure facility operated by and for students with the goal of elevating experiential education and undergraduate student research.   Encompassing over 1000 sq. ft of space in the Love Manufacturing Building, The MILL is staffed by over 40 undergraduate students and is open 30+ hours per week for all students on campus to learn and do materials processing, characterization, and property measurement.  Stop by Love 176 today!
