Julio was born in Costa Rica. He received a B.S. in Bioinformatics from the University of California at San Diego in 2005 with Summa Cum Laude and was accepted to the Interdisciplinary Graduate Bioinformatics Program at UCSD where he studies under the supervision of Dr. Pavel Pevzner. Julio is interested in developing algorithms for characterization of biomedically important proteins and peptides using mass spectrometry. These studies include identification of fusion proteins in tumors and, more recently, identification of non-ribosomal peptides that represent potential drugs like antibiotics and immunosuppressors. Julio co-chairs the Student Council of the Program for Bioinformatics and Systems Biology at UCSD.
