Valentina began her postdoctoral training conducting preclinical studies to target senescent cells in the treatment of Alzheimer’s disease pathology in mouse models of tauopathies, and is now contributing to the translation of these exciting studies into early pilot and phase II clinical trials exploring senolytic treatments for the progression of Alzheimer’s disease. 


Scholar: Clare Murray

Degree Sought: Ph.D.                                                                                                                                          Program: Molecular Immunology & Microbiology                                                                                           Research Interest: Cancer Biology, Immunology Mentor: Tyler Curiel, M.D., MPH,  Department of Medicine /Hematology & Medical Oncology                                                                                                 

Research Topic: Pharmacologic PD-L1 depletion improves tumor response to DNA damage repair inhibitors and aPD-L1 through reduced tumor intracellular PD-L1 signals and non-canonical immune effects

Clare Murray is a fourth year student in the South Texas Medical Scientist Training Program (MSTP). She graduated with a Bachelors of Science in Chemical Engineering in 2018 from the University of Texas at Austin. During her undergraduate studies, Clare studied under Dr. Hal Alper to study the genetic engineering of the oleaginous yeast Y. lipolytica for the production of polyketides. As a summer intern, she worked with Dr. Dario Marchetti at the Houston Methodist Research Institute to study the role of circulating tumor cells in melanoma and triple negative breast cancer brain metastasis. After graduating, Clare matriculated into the South Texas MSTP program and completed the first two years of medical school. She is now in her second year as a graduate student in the department of Microbiology, Immunology, and Molecular Genetics under the mentorship of Dr. Tyler J. Curiel. Clare’s research in Dr. Curiel’s lab focuses on investigating tumor cell-intrinsic signals of PD-L1 and the potential to target these signals with novel PD-L1 depleting drugs. While tumor PD-L1 canonically signals to tumor infiltrating lymphocytes to evade anti-tumor immunity, PD-L1 also has tumor cell-intrinsic signals, including control of mTOR, autophagy, and tumor initiating (stem) cells. Clare’s work during her time as a TL1 scholar will focus on repurposing novel FDA-approved drugs to deplete tumor PD-L1, thus disrupting these signals and sensitizing drug-resistant tumors to select therapies with rapid translational potential.

Degree Sought: Ph.D.                                                                                                                                          Program: IBMS - Microbiology, Immunology & Molecular Genetics                                                                      Research Interest: Malaria, Immunology Mentor: Evelien Bunnik, Ph.D., Assistant Professor, Department of Microbiology, Immunology & Molecular Genetics                                                                                   

Research Topic: In-depth analysis of broadly protective immune responses against the malaria parasite variant surface antigens responsible for cerebral malaria

Raphael Reyes is a third-year PhD candidate in the department of Microbiology, Immunology, and Molecular Genetics. He graduated with a Bachelor’s of Science in Biology in 2017 from the University of California, Riverside. As an undergrad, Raphael studied the regulation of gene expression and chromatin structure in Plasmodium falciparum, the causative agent of malaria, in response to epigenetic drugs. After graduation, Raphael continued his research career at the University of Missouri-Columbia, where he was selected to participate in an NIH post baccalaureate research education program. In 2018, Raphael began his matriculation at UT Health San Antonio’s Integrated Biomedical Sciences PhD program. His dissertation work is under the guidance and supervision of Dr. Evelien Bunnik. During the Translational Science Training TL1 Award, Raphael’s research will focus on the identification and characterization of broadly protective immune responses against the malaria parasite antigen responsible for severe disease. Raphael’s work will involve the use of donor samples from individuals naturally infected with P. falciparum to study malaria specific B cells and their respective antibodies contributing to disease protection. His findings will facilitate the development of a vaccine against severe malaria by identifying the exact antigen epitopes that need to be targeted.
