About Me
Hi! my name is Mariagiovanna Rotundo and I’m a Ph.D. student in computer science at the University of Pisa. I’m currently working on topic of succinct data structures and, with my supervisors, I’ve published my first scientific paper. In my spare time, I’m an active member of the two local communities GDG and WTM Pisa, which organize free talks about different topics and technologies in the field of computer science.
I am most skilled in: Java, Problem solving, and Organization
Professional Experience
Ph.D. student

Nov 2023 - Present
I’m a Ph.D. student :D
Research Fellow
University of Pisa
Jan 2023 - Nov 2023
Working on the topic “Compressed data structures to index datasets of keys with variable length”. We study the problem of engineering space-time efficient indexes that support membership and lexicographic queries on very large static dictionaries of strings. The solution we propose is based on a very simple approach that consists of decoupling string storage and string indexing. Supervisors: Paolo Ferragina, Giorgio Vinciguerra.
Education
Master's degree in Computer Science
University of Pisa
2020 - 2022
I’ve attended the curriculum “ICT Solutions Architect” where, among all the topics, I’ve studied how to design heterogeneous and distributed software systems and how to well parallelize software. I graduated with the grade of 110/110 cum laude with a thesis where we’ve proposed a solution for compressed string dictionaries via Rear coding and succinct Patricia Tries. My supervisors were Paolo Ferragina and Giorgio Vinciguerra.
Bachelor's degree in Computer Science
University of Pisa
2017 - 2020
I’ve learn the basis about different topics in IT. I’ve graduated with the grade of 110/110 cum laude with a thesis where we’ve proposed a python package for the batch simulation of chemical reaction networks. My supervisors were Paolo Milazzo and Lucia Nasti.

Projects
-
Two-level indexing
Master’s degree project extended to implement the data structures and algorithms published in SPIRE 2023. C++ -
Parallel BFS
University project for Parallel and Distributed System course. Implementation and performance comparison of a parallel Breadth-first search (BFS) using the standard thread library and FastFlow. C++ -
SBML-batch
Bachelor’s project to analyze collections of chemical reaction networks. Our goal was to (i) provide an implementation of 2 Theorems that under some conditions can give us information on how the networks behave, (ii) create a package to simulate in batch a lot of chemical reaction networks, (iii) provide an implementation to automathically build the Petri Nets of the chemical reaction networks.
