Tim Lieuwen, professor of Aerospace Engineering and Mechanical Engineering at the Georgia Institute of Technology, was awarded the George Westinghouse Silver Medal by the American Society of Mechanical Engineers at the organization’s annual International Mechanical Engineering Congress and Exposition in November. Lieuwen was honored for his "outstanding contributions to combustion science and technology for low-emission gas turbines."

The George Westinghouse Medals were established by ASME to recognize eminent achievement or distinguished service in the power field of mechanical engineering. The silver medal is given to an individual under the age of 45.

In 1999, Lieuwen began his academic career as an assistant professor in the School of Aerospace Engineering after completing his Ph.D. in mechanical engineering at Georgia Tech. Lieuwen maintains an active teaching and research program in the area of clean combustion.

Karim Sabra, assistant professor of Mechanical Engineering, was awarded the R. Bruce Lindsay Award from the Acoustical Society of America for his work on time-reversal acoustics and ambient noise cross-correlations. 

The R. Bruce Lindsay Award is presented in the spring to a member of the society who is under 35 years of age and who, during a period of two or more years immediately preceding the award, has been active in the affairs of the society and has contributed substantially, through published papers, to the advancement of theoretical and/or applied acoustics. 

Sabra began his career at Georgia Tech in 2007 as an assistant professor. Prior to Tech, he was a project scientist at the Marine Physical Laboratory of the Scripps Institute of Oceanography of the University of California at San Diego.  His research at Georgia Tech emphasizes an interdisciplinary approach to applied and theoretical problems in acoustics, structural health monitoring, biomechanics and seismology based on common wave propagation physics features.
