Asensio’s research comprises studying the application of wide-ranged in-house and Synchrotron Radiation Based techniques devoted to the spectroscopic characterization of ground-breaking materials in the area of Solid-State Physics. She focuses on the structural and electronic properties of surfaces, interfaces, and complex materials. She is a specialist in angle-resolved photoemission spectroscopy (ARUPS), synchrotron radiation Photoemission (SR-PES), and X-Ray absorption (XAS), among other conventional characterization materials science techniques. She mainly focused on determining the Fermi surface topology and electronic band structure of interfaces and massive materials, which frequently present electronic instabilities due to low dimensional effects. She has recently conceived and realized an innovative chemical and electronic imaging spectroscopic technique combining angle-resolved photoemission and nano- and microscopy, named “nanoARPES.”. She has more than 261 international journals, 1 book chapter, and more than 100 invited lectures. – Factor H: 47 and i10-index: 159, with more than 10800 citations, (Google scholar).
