Dr. Sissy Nikolaou
Dr. Nikolaou is an Associate of Mueser Rutledge Consulting Engineers which she joined in 1998. She is Director of the firm’s Geo-Seismic department and holds PhD and MS degrees from SUNY-Buffalo and a Diploma from National Technical University of Athens, all in Civil Engineering. Her areas of specialization are Seismic Hazard Analysis, Soil-Structure Interaction, and GIS Engineering Applications with more than 30 scientific papers and numerous research activities. Dr. Nikolaou is working on major projects involving long-span bridges, nuclear power plants, deep excavations, tanks, and high-rise buildings. She holds professional licenses in New York and Europe and she is FEMA-certified to conduct post-earthquake safety structural evaluations and provide strategies for urban search-rescue teams when responding to seismic hazards in emergency situations. She has served on many scientific committees, most recently for the upcoming NYC Building Code. In 2003 Dr. Nikolaou was honored with the Prakash Prize for Excellence in the Practice of Geotechnical Engineering and in 2006 she was named one of the 40-under-40 leaders in the Building Design and Construction industry. Recently she was selected as one of the eighty-three young engineers of all disciplines nationwide to take part in the National Academy of Engineering’s Frontiers of Engineering.
