Current position of Stefano Ricci:Researcher at the Engineering Information Department of the University of Florence,
Stefano Ricci received a degree in Electronics Engineering from the University of Florence in 1997, and, in 2001, he obtained a PhD degree in Electronic Systems Engineering. Since 2006 Stefano Ricci holds a Researcher permanent position in the Engineering Information Department (formerly Electronics and Telecommunications Department ) of the University of Florence.The research interests of Stefano Ricci include the design and development of electronics systems for data acquisition and real-time data processing. In particular Stefano Ricci gained a wide experience in the design of advanced ultrasound systems for biomedical [J4], [J9] and industrial applications [J16]. Recently Stefano Ricci contributed to the design of a complete research echograph [J11], [J15] with 64 independent channels multiplexed over 192-transducer probes. All of these systems are based on advanced digital devices, like DSPs and FPGAs, which grant high programmability and flexibility.Stefano Ricci works on the development and test of novel ultrasound methods as well. His activity has been in particularly focused on Doppler techniques for the accurate assessment of moving-fluids characteristics. For example, by exploiting the features of the aforementioned systems, he tested several vector methods for an accurate measurement of blood velocity in arteries [J10], [J13], [J21], [J24]. Stefano Ricci extended a mathematical model for the assessment of the Doppler spectrum measured from a flowing fluid [J22], and exploited it for blood peak velocity measurements in arteries [J24]. He implemented and tested a method for volume flow measurement [J19] and experimented new spectral estimators for the detection of the Doppler spectrum [J18].Stefano Ricci collaborates with national and international research institutions and industries like University of Lund (Svezia), University of Toyama (Japan), Erasmus MC (Netherlands), Università di Pisa, Università di Roma, Esaote s.p.a. (Genova, Italy), Sika l.t.d. (Zurich), SP Technical Research Institute of Sweden (Sweden), Microtest (Italy), etc. in projects funded by national and international institutions.Stefano Ricci is currently in charge of the “Digital Electronics Laboratory” course of the degree in Electronics and Telecommunications, and the “Digital System Design” course of the master degree in Electronics at the University of Florence. Stefano Ricci is tutor of 2 PhD students of the Engineering Information PhD course and has been tutor of tens of bachelor and master thesis students.Stefano Ricci published more than 80 papers on international journals and international conference proceedings. He is reviewer for journals like ‘IEEE Transacion on Ultrasonics, Ferroelectrics and Frequency Control’ and ‘Ultrasound in Medicine and Biology’. According to Scopus database his h-index is 14.
