Corsi per la scuola di dottorato
I have followed the next three courses for the Phd school:
• Fisica Medica, magistrale in fisica UNIPI, primo semestre corso 2015-2016
• High frequency finance and microstructure of financial markets, SNS, second semester, year 2015-2016

External schools
I have followed 6 external schools
• First GraWIToN school, held at European Gravitational Observatory (EGO) in Cascina from the 20 of April to the 8 May 2015. It was an introductive school with the courses focused on the different fields present on gravitational wave science. The courses were on data analysis, optics, simulation, high power lasers and multidisciplinary skills. • First data analysis school of the GraWIToN project, held at Gran Sasso Science Institute.
Organized from the 9 of November to the 13 of November of 2015. The school focused on modelling possible sources of gravitational waves and how the signal could be extracted from the data.
• First Technical school focused on lasers, optics and simulations, held at the school of physics in Birmingham, UK. It was organized from the 25of January to the 29 of January of 2016.
• Second Technical school focused on lasers, optics and simulations, held at the Max Planck Institute for Gravitational Physics in Hannover, Germany. It was organized from the 12of September to the 16 of September of 2016.
• Project management school, held at EGO in Cascina from the 21 of November to the 25 of November of 2016.
• Data Analysis: Pandas, Machine Learning, Dictionary Learning October 2016, an introduction to machine learning techniques was presented during 2 days.
Conferences
During this period, I have attended to the next conferences
•
Iberian Gravitational Wave Meeting 2015 (IGWM15) in Barcelona, Spain between the 12th and the 14th of May of 2015. http://www.ice.csic.es/research/IGWM2015/• Gravitational waved advanced detector workshop (GWADW16) at Isola d’Elba, between the 22nd and the 28th of May of 2016
• Amaldi conference in Pasadena, CA, USA. It was held between the 9th and the 14th of July of 2017. During the conference I presented a poster with the title “Estimating noise from stray light with ray tracing” and I gave a talk with the title “Current status of noise hunting in Advanced Virgo”
• LVC meeting in August 2017 at CERN. I did not attend, but I was co-author of a poster with the title “Scattered light noise investigation at Advanced Virgo”
• Einstein telescope Design Update Worksop in Glasgow, UK in September 2017. I presented a short talk about my PhD project.

• I have assisted to the Virgo week, organized once each three months at EGO.
Outreaching
During this time, I have collaborated with several outreaching activities:
• 5 Jun 2015, activity organized by EGO at chiesa Sant’Andrea in Pisa. My work was an explanation of my experience as researcher and as a person who moved into a new country to high school students.
• 17 December 2015, presentation during the opening of the AISF (Associazione Italiana di Studenti di Fisica) meeting in Pisa.
• EGO researcher’s night 2015. I stayed in the stand “European corner”, where I explained the principles of Virgo interferometer and the different opportunities in research for young people.
• Internet festival, 6-9 of October 2015. I performed demonstrative activities about the working principles of Virgo using a model of the Michelson interferometer.
• Researcher’s night 2017. I participated in the INFN stand in front of the Scuola superiore sant’Anna, Pisa
• Collaboration for a journal article of Agencia EFE (Spanish news agency):

Periods outside UNIPI
During my Phd I have spent some period in external institutions:
• EGO, Cascina. In addition of the short visits I have done during the different conferences and courses, I have gone in a daily basis in two periods. The first is during March-April 2015, where I learned the working principles of Virgo and the second is during June-July 2017 to collaborate with the commissioning before the scientific run of Advanced Virgo. • University of Birmingham, UK. I have spent a period of three weeks during February
2017 learning the working principles used to control optical cavities.
• Collaboration with TRII company, Florence and Antonio Cisternino, Dipartimento di informatica, UNIPI. Valuation of the heterogeneous programming for the acceleration of the code. Activity finally carried out at the university where the servers are located.
Other
The 26 of October I participated in a special event at the Research Executive Agency (REA), in Brussels to present the work developed during the GraWIToN project.
I have been tutoring one group on the “Laboratorio 1” course from laurea Triennale in fisica. I did it during my second and third course of the Phd.
