Dr. Santoso joined the Department of Electrical and Computer Engineering at the University of Texas at Austin in September 2003. His research lies in the broad area of power systems analysis, electric power quality, wind power integration and interconnections, and time-domain modeling and simulation of electrical systems. He established and directs the Laboratory for Advanced Studies in Electric Power and Integration of Renewable Energy Systems (ASPIRES).

He received his B.S. degree from Satya Wacana Christian University, Salatiga, Indonesia, in 1992 and his M.S. and Ph.D. degrees from the University of Texas at Austin in 1994, and 1996, all in electrical engineering. He was a postdoctoral fellow under the auspices of Electric Power Research Institute in 1997. From 1997 to 2003, he was a senior power systems and consulting engineer with Electrotek Concepts, Knoxville, TN.

Dr. Santoso has carried out a wide variety of power systems studies ranging across generation (planning and operation, economic dispatch, unit commitment), transmission (system interconnection, ATC, load flow, dynamic stability) and distribution (power quality, distributed generation).

Examples of these studies include but are not limited to wind power integration and interconnection studies, wind turbine and plant modeling, subsynchronous resonance, capacitor switching transients, ferroresonance, breaker transient recovery voltage (above and below 100 kV) evaluation, lightning protection, arrester sizing, and series capacitor bank protection. He was also a lead developer for many intelligent systems algorithms such as capacitor bank switching transient waveform recognition and direction, voltage sag waveform recognition and direction, and radial fault distance estimator. These algorithms (commercialized as AnswerModule) are embedded in an advanced power quality monitoring platform, Dranetz Encore (formerly known as Signature Systems).

He is actively involved in the IEEE Power and Energy Society. He is a fellow of IEEE and chaired a task force on intelligent system applications to data analysis. He is also a member of several working groups such as Distributed Resources, Harmonics, and Series Capacitors. He authored Fundamentals of Electric Power Quality, and a book-chapter Power Quality and Reliability, in Standard Handbook for Electrical Engineers, 15^th edition, McGraw-Hill (2006), and co-authored a professional series engineering book with Roger C. Dugan, Mark F. McGranaghan, and H. Wayne Beaty, Electrical Power Systems Quality published by McGraw-Hill in 2003. He has published over 60 technical papers in electric power quality and wind power systems.
