Robertson Esperanza

Robbie graduated cum laude from the BS Applied Physics program in 2017 and completed the MS Physics program in 2020. He was supported by a DOST-SEI RA 7687 Undergraduate S&T Scholarship. His research involved using density matrix renormalization group (DMRG) techniques to map out the ground phase diagram of a one-dimensional extended Hubbard model from its correlation functions and entanglement entropy. Robbie was also a student assistant for the OVCRD-funded Project No. 161614 PhDIA. He is now a data scientist working for a credit and finance company.
