Reference excerpt

Mehmet Önder Efe is a Turkish control systems engineer and academic. He is a professor in the Department of Computer Engineering at Hacettepe University in Ankara, Turkey, where his research focuses on control systems, robotics, neural networks, unmanned aerial vehicles, and machine learning. He served as co-Editor-in-Chief of Transactions of the Institute of Measurement and Control from 2017 to 2022 and has held associate editor positions at several IEEE journals.

Early life and education Efe completed his B.Sc. in Electronics and Communications Engineering at Istanbul Technical University in 1993. He went on to obtain his M.Sc. in Systems and Control Engineering from Boğaziçi University in 1996, and his Ph.D. in Electrical and Electronics Engineering from the same institution in June 2000, under the supervision of Okyay Kaynak. His doctoral dissertation was recognised with the Ph.D. Thesis Award of the Boğaziçi University Research Fund.

Career Between August 1996 and December 2000, Efe was a research assistant at the Mechatronics Research and Application Center of Boğaziçi University. In 2001 he joined Carnegie Mellon University as a postdoctoral research fellow in the Department of Electrical and Computer Engineering, where he was a member of the Advanced Mechatronics Laboratory and worked on a distributed robotics project funded by the U.S. Defense Advanced Research Projects Agency (DARPA). From January 2002 to July 2003 he was a postdoctoral research associate at the Ohio State University Department of Electrical Engineering, contributing to an aerospace research project supported by the Air Force Office of Scientific Research (AFOSR). Following his return to Turkey, he served as an assistant professor in the Department of Mechatronics Engineering at Atılım University from 2003 to 2004. In 2004, he moved to the Department of Electrical and Electronics Engineering at TOBB University of Economics and Technology as an associate professor, and in 2009 he was promoted to professor at the same institution. He chaired the department from 2004 to 2007 and again from 2008 to 2010, and took part in establishing the university's master's and doctoral programs in electrical and electronics engineering. From 2010 to 2011, he worked as a professor in the Department of Electrical and Electronics Engineering at Bahçeşehir University. In 2011, he was appointed professor at the University of Turkish Aeronautical Association, where from 2011 to 2013 he served as dean and vice rector in the Department of Flight Training of the Faculty of Air Transportation. In 2013, he joined the Department of Computer Engineering in the Faculty of Engineering at Hacettepe University as a professor, and chaired the department from 2015 to 2018. He has headed the Computer Hardware Division since 2013 and, since 2014, the Division of Digital Communication Systems and Computer Networks at Hacettepe University's Informatics Institute.

Research Efe's research lies at the intersection of control theory and machine intelligence. His published work includes contributions to sliding mode control, adaptive control, disturbance observer design, fuzzy logic-based control, proper orthogonal decomposition-based reduced-order modelling of distributed parameter systems, and the design and control of quadrotor and other unmanned aerial platforms. More recent research, carried out with collaborators in Europe and East Asia, has addressed adaptive disturbance and uncertainty estimators for linear time-invariant systems, equivalent-input-disturbance methods for unmatched systems, and continual-learning approaches based on switched neural networks with preselected masks. According to Google Scholar, his publications have received more than 5,000 citations. He has authored or co-authored more than 210 technical publications, including conference proceedings, journal articles, and book chapters.

Editorial and professional service Efe served as co-Editor-in-Chief of Transactions of the Institute of Measurement and Control, published by SAGE on behalf of the Institute of Measurement and Control, between 2017 and 2022, after which he continued to serve on the journal's advisory board. He has also been an editor of Measurement and Control and a founding editor of an IEEE journal in the area of artificial intelligence. He has served as associate editor for several IEEE periodicals, including IEEE Transactions on Industrial Electronics, IEEE Transactions on Industrial Informatics, IEEE/ASME Transactions on Mechatronics, and IEEE Transactions on Artificial Intelligence. Additional editorial board appointments have included the Turkish Journal of Electrical Engineering and Computer Sciences, Mathematical Problems in Engineering, Advances in Fuzzy Systems, and International Journal of Industrial Electronics and Control. Efe is among the founding members of the Turkish chapter of the IEEE Computational Intelligence Society, established in 2025.

Awards Efe is a three-time recipient of the Turkish Academy of Sciences (TÜBA) Copyrighted Work Award, given to outstanding academic textbooks in Turkish:

2011 / 2012 – for the two-volume Circuit Analysis I and Circuit Analysis II. 2014 – for Automatic Control Systems. He also received the Ph.D. Thesis Award of the Boğaziçi University Research Fund for his doctoral work.

Worked examples

Example 1 — a first encounter with Mehmet Önder Efe

Start with the simplest possible case. Write down what Mehmet Önder Efe claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Mehmet Önder Efe before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Mehmet Önder Efe ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Mehmet Önder Efe

In research: Mehmet Önder Efe appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Mehmet Önder Efe in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Mehmet Önder Efe is common in secondary-school and first-year university syllabi. It links to neighbouring topics Academic staff of Hacettepe University, Boğaziçi University alumni, Carnegie Mellon University people, so understanding it makes those chapters shorter.
In everyday life: Look for Mehmet Önder Efe outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
