Greg Spiro is currently serving as Executive Director of Infrastructure, overseeing operational teams in utilities, buildings and grounds. He is a licensed engineer, LEED AP and CEM with more than 30 years of mechanical systems experience and has worked at Georgia Tech for over 25 years. He leads the Energy and Infrastructure initiative at the Georgia Tech Strategic Energy Institute. 

Throughout his time at Georgia Tech, Spiro has taken an active role in promoting and enforcing Georgia Tech's standards and sustainability initiatives. His past work includes the planning, development and tracking of the Kendeda building (built to meet all imperatives of the Living Building Challenge), implementation of Guaranteed Energy Savings Performance contracts, management of Georgia Tech’s Utility Analytics team, project management team member for Georgia Tech’s Comprehensive Campus and Climate Action Plans and most recently management of Georgia Tech’s Utility Masterplan, that defines utility needs and improvements that align with Georgia Tech’s emission reduction goals as well as support campus construction prioritized for the next decade. Spiro has also served as a voting member on the ASHRAE BACnet committee. 

Dr. Realff’s broad research interests are in the areas of process design, simulation, and scheduling. His current research is focused on the design and operation of processes that minimize waste production by recovery of useful products from waste streams, and the design of processes based on biomass inputs. In particular, he is interested in carbon capture processes both from flue gas and dilute capture from air as well as the analysis and design of processes that use biomass.

Our group is primarily a surface chemistry and physics group which focuses on the use of high-powered pulsed lasers, low-energy electron scattering, micro-plasmas, mass spectrometry and ultrahigh vacuum surface science techniques. We use this "tool-set" as well as some scattering theory to unravel the details of non-thermal processes occurring under a variety of non-equilibrium conditions. Our group is based upon an interdisciplinary approach and thus our research programs span the realm of fundamental investigations in molecular physics, surface physics and chemistry, bio-physics, bio-polymer formation under pre-biotic conditions as well as working in applied areas of relevance to analytical technique developments, atmospheric chemistry, catalysis and molecular hydrogen generation.

Dr. Ng is the Love Family Professor in the School of Chemical & Biomolecular Engineering and the School of Earth & Atmospheric Sciences at the Georgia Institute of Technology. She earned her Ph.D. in Chemical Engineering from the California Institute of Technology and was a postdoctoral scientist at Aerodyne Research Inc.

Dr. Ng’s research focuses on the understanding of the chemical mechanisms of aerosol formation and composition, as well as their health effects. Her group combines laboratory chamber studies and ambient field measurements to study aerosols and air quality using advanced mass spectrometry techniques. Dr. Ng leads the establishment of the first, high time-resolution, long-term aerosol measurement network in the U.S.: Atmospheric Science and Chemistry mEasurement NeTwork (ASCENT), for characterization of aerosol chemical composition and physical properties, and their impacts on climate, human health, and ecosystems.
