Dr. Peláiz-Barranco was born in June 25th, 1972, in Havana, Cuba. All her studies were developed in Cuba. She began her physics studies in the Physics Faculty, Havana University, in 1990. She developed scientific activities since the second year of her studies and presented her works in the workshops of the students at the Physics Faculty and also at the Havana University. She finished her physics studies in 1995 with very good results and was selected to work in the Physics Faculty.
Since 1996 she began to develop (as a member of the Ferroelectric Group from the Physics Faculty-IMRE, Havana University) some national and international projects. She presented her Master in Science Degree Thesis in 1996 and won by contest her first permanent position in 1997 as instructor in the Applied Physics Department of the Physics Faculty, Havana University. After that she began her studies to obtain the Physics Doctor Degree. Her thesis was successfully presented in 2001. She won a permanent position as Assistant Professor in 2002 and as Auxiliary Professor in 2009. She was appointed as Vice-Dean of Faculty of Physics at Havana University in 2006 (until today).
She is very active as a teacher in pregrade and postgraduate courses. She has also delivered lectures on ferroelectric materials in Universities from Mexico and Brazil.
Today she develops scientific projects on ferroelectric materials with Institutions from Mexico, Brazil, Spain, United Kingdom (supported by the Royal Society) and France. She has developed three Research Grants from TWAS as principal researcher.
She has authored more than 50 papers in high quality international journals and other 40 have been published in national journals and proceedings of national and international meetings. She also has authored more than 100 works, which have been presented in international meetings, and more than 40 in national meetings.
She has supervised undergraduate, Master and PhD thesis. Since 2009, she is member of the National Jury of Physics Doctor Degree. She is also a full member of The Third World Organization for Women in Science (TWOWS). Since 2002, she is a Young Associate of The Academy of Science of Cuba. She has received an important numbers of Awards for her scientific results: Three Prizes of the Sciences Academy of Cuba (1999, 2001, 2005), National Prize Young Research of the Cuban Science and Technology Minister in the Section of Natural Sciences (2003), Prize "Sofia Kovalieskaya" (2003), Young Researcher Award given by the Journal Physica Status Solidi during the XVII Latin-American Symposium of Solid State Physics. Havana, Cuba (December 6th-9th, 2004) and others.
Since 2000, she is the international coordinator of the "Latin-American Network on Ferroelectric Materials" (Network of ICTP), which was created to promote the scientific research on ferroelectric materials in Latin-America and also to contribute to the formation of students and new researchers.
Dr. Pelaiz-Barranco belongs to the Ferroelectric Group of Physisc Faculty-IMRE, Havana University. The piezo- piro-, ferro- and dielectric properties of ceramics and ceramic/polymer composites are areas of her interest. She has studied in detail those properties in a wide group of materials; some of these materials were reported for the first time in her papers. Her studies on those materials have contributed to the development of some devices, which are using in the medicine and the industry in Cuba. Her researches have made emphasis in the importance of the impedance spectroscopy to evaluate the dielectric relaxation behavior and the contribution of the electrical conductivity to the electrical response of ferroelectric materials in a wide frequency and temperature ranges (under different electric fields and hydrostatic pressure conditions). Her work has showed how the impedance spectroscopy can lead to a better understanding of the dielectric response of ferroelectric materials. It includes the dependence of the dielectric relaxation and the electrical conductivity on experimental conditions as the chemical compositions, processing methods, electric fields and hydrostatic pressure, which can be understood more completely. Concerning this kind of analysis, she has also contributed to the analysis of the electrical response of ferrimagnetic and catalytic materials. She is a young hard working scientist whose activities range from teaching, tutor of pregrade and postgraduate thesis, and to de research of very high quality. On the other hand, her initiative has lead to the development of an important international project, the Latin American Network of Ferroelectrics Materials (an ICTP Network with 14 Latin-American Institutions). Dr. Pelaiz-Barranco is the international coordinator of the project, whose activities (most of them have been organized by her) have contributed to promote the scientific research in areas where the institutions are facing budgetary restrictions and also to the formation of students and new researchers.
