Kaisorn Chaichana

Kaisorn Chaichana, currently a neurosurgery resident at The Johns Hopkins Hospital, is completing a year-long research fellowship funded by the American Brain Tumor Association (ABTA). Kaisorn received his B.S. in 2003 from the University of Utah and majored in Biology. Kaisorn joined the Brain Tumor Stem Cell Lab in June 2006. He is interested in studying the effects of epidermal growth factor (EGF) on the migration of normal neural stem cell and tumor stem cell migration. In addition, he is trying to determine the phenotype of the invading brain tumor cells that make brain tumors resistant to treatment.

Neurosurgical Fellows

Jordina Rincon-Torroella

Jordina first joined Dr. Quiñones’s team in March of 2012 during her sub-internship at the Department of Neurosurgery. Jordina received her medical degree from the University of Barcelona, Hospital Clínic in February 2013. She joined us again in July 2013 and is currently working as a content developer for various neurosurgical books that will be groundbreaking in the field of neurosurgery as the "Comprehensive multimedia video-atlas of skull base surgery and tumors" and the upcoming "Schmidek and Sweet neurosurgical handbook." She is also involved in various research projects as part of Dr. Quinones´s team.

Jordina will start a neuro-oncology research fellowship with us in 2014 sponsored by the Fundació "La Caixa." Her research interest are tumorgenesis, the treatment of high-grade gliomas and surgical approaches to skull base lesions.

Grants and sponsors:

Fundació Riera i Gubau scholarship for clinical rotations at the US (Government of Catalonia) - 2012
Fundació Pedro i Pons scholarship for research projects at the US (University of Barcelona) - 2013
Sponsored by Elsevier as a video-editor for the book "Comprehensive multimedia video-atlas of skull base surgery and tumors"

João Paulo Almeida

João Paulo Almeida is a senior neurosurgery resident at the State University of Campinas (UNICAMP) in São Paulo, Brazil. He received his medical degree in 2008 from the Federal University of Ceara, Brazil. Before joining Dr. Quinones’ team, João Paulo has worked in several projects in the field of endoscopic pituitary surgery in collaboration with the Neuroendocrinology Study Group of the General Hospital of Fortaleza as well as in microanatomy and microsurgical techniques courses, papers and book chapter in collaboration with the world renowned neurosurgeon Dr. Evandro de Oliveira, MD.
He first worked with Dr. Quinones’s team in 2008 during his subinternship at the Department of Neurosurgery and then as visiting fellow of the Brain Tumor Stem Cell Lab. He returned to Hopkins in February 2014, this time as a fellow, and is working in pituitary tumors, gliomas and meningiomas clinical studies as well as in the development of new surgical approaches and book projects.
João Paulo’s main clinical interest includes neuro-oncology, pituitary adenomas surgery and endoscopic and microsurgical anatomy and surgical techniques.

2. Human Physiology Scholarship – Medical School of Federal University of Ceara: 2006.

Ignacio Jusué-Torres

Dr. Ignacio Jusué-Torres received his medical degree from the Universitat de Barcelona in 2006 and finished his Neurosurgical training at the Hospital Universitario de Getafe (Madrid) in May 2012. He joined the Neuro-Oncology Surgical Outcomes Laboratory in 2012. His clinical interests include neuro-oncology; specifically, the surgical treatment of gliomas and pituitary tumors.

Dr. Jusué-Torres' current research projects include:

Volumetric analysis of extent of resection impact in gliobastoma’s outcomes
Volumetric analysis of brain mapping impact in extent of resection
Prospective study of correlation of clinical and volumetric changes in non-surgical management of brain tumors.
