text: # Petros A. Ioannou
  
  Petros A. Ioannou is a Cypriot American Electrical Engineer who made important contributions in Robust Adaptive Control, Vehicle and Traffic Flow Control, and Intelligent Transportation Systems.
  
  ## Early life and education
  
  Petros A. Ioannou was born in the village of Tripimeni in Cyprus. After graduation from the Technical School of Nicosia and completion of his compulsory military service he moved to London, England in 1973 to attend University College London. He graduated with First-class honours from University College London with a B.S. in mechanical engineering in 1978. He earned a M.S. in mechanical engineering and a Ph.D. in electrical engineering from the University of Illinois at Urbana–Champaign in the area of Robust Adaptive Control under the supervision of doctoral advisor Petar V. Kokotovic.
  
  ## Career
  
  Ioannou became an assistant professor at the University of Southern California in 1982 and was subsequently promoted to associate and full professor. He is currently a full professor in the Department of Electrical and Computer Engineering at the University of Southern California where he holds courtesy appointments in the Departments of Aerospace and Mechanical Engineering and Industrial and Systems Engineering. He is the holder of the A.V. Balakrishnan Endowed Chair. He is the founder and director of the Center for Advanced Transportation Technologies and co-founder and associate director for research of the Metropolitan Transportation Center METRANS as well as the director of the Master Program on Financial Engineering. On February 09, 2022, he was elected as a member of the National Academy of Engineering (NAE) for his contributions to robust adaptive control and intelligent transportation systems for improved traffic flow and driver safety. In 2022, Ioannou was also elected to the Academia Europaea and to the National Academy of Inventors.
  
  ## Research
  
  Ioannou’s multidisciplinary research focusses on solving problems related to automatic control with applications in the areas of vehicles, intelligent transportation systems, aircraft, computer disks servo control, noise and vibration cancellation and other applications. He is an expert in Robust Adaptive Control and he is known for the use of σ-modification and switching σ-modification in establishing robustness in Adaptive control. He was one of the pioneers in making adaptive control practical by proposing robustness modifications that prevent instabilities and guarantee performance and robustness. He has been working on advanced vehicle concepts that involved drive by wire, steer by wire and later on cruise control and intelligent cruise control systems in collaboration with major automotive companies in the US. Intelligent cruise control systems also known as Adaptive Cruise Control (ACC) systems allow automatic vehicle following with collision avoidance capabilities for safety and driver comfort in addition to positive environmental impact. He was the first to prove that ACC systems can be designed to guarantee stable vehicle following known as string stability without using vehicle to vehicle communication .
  
  Ioannou’s research also involves the design of control systems for vibration control with applications to laser pointing devices, mechanical systems, noise cancellation devices and disk drive servo control and camera image stabilization.
  
  His research in the area of transportation involves traffic flow modeling and control as well as freight optimum routing and port automation. The development of a traffic simulation of the road network that feeds into Los Angeles International Airport allows the evaluation of different technologies and concepts that influence the traffic around the terminals.
