Congratulations to Christian Gallardo for a Successful PhD Dissertation Defense!
(July 10, 2020)
The Torbett Lab would like to congratulate Christian Gallardo for successfully defending his doctoral dissertation on July 10, 2020, entitled: “Novel Sequencing Strategies for Interrogating HIV Activation Dynamics in Infected Host Cells and Tracing Viral Evolution at the Single Molecule Level”.
His work sought to address the potential role of alternative splicing during HIV latency and reactivation from latency. To undertake these studies, he developed a quantitative full-length RNA-seq methodology allowing simultaneous profiling of poly-adenylated HIV and host cell transcripts from the J-Lat cell line model of viral latency. These studies resulted in the identification of what appears to be a novel pathway that may modulate Gag assembly. Christian’s work also sought to address the role of novel mechanisms of drug resistance to antiretrovirals in circulating HIV virions. For this, he developed a nanopore-based long-range sequencing methodology to obtain accurate HIV cDNA sequences covering the entire Gag-Pol region from clinical isolates, with the goal of tacing of novel evolutionary pathways that result in drug failure.
Dr. Bruce Torbett supervised his research. The disseration committee included Juan C. de la Torre, Ph.D., Brian M. Paegel, Ph.D. and Ali Torkamani, Ph.D., while Jesse Bloom, Ph.D. of the Fred Hutchinson Cancer Research Center, served as an external examiner.
Christian began his studies at the Torbett Laboratory as a Graduate Student in 2015 through the Scripps Research Institute’s Skaggs Graduate School of Chemical and Biological Sciences. He plans to continue his work on viral genomics, with an emphasis on decoding how viral RNAs modulate fitness at different stages of the viral lifecycle.

Torbett Lab Welcomes Three New Members (August 1, 2019)
As the Torbett Lab expands, three new members have been recruited. Each of therm brings knowledge, experience and skills that add a unique perspective to advance the lab’s research projects.
Christina Garza
Christina Garza is a MD/PhD graduate student of University of California San Diego. She is currently working on her doctoral degree through the Scripps Research Institute’s Skaggs Graduate Program. Her co-mentored project will combine faculty expertise in HIV structure and function (Torbett) and molecular modeling (Forli) and will allow her to perform studies of the HIV capsid. Christina’s project will focus on evaluating the contribution of Gag/Pol proteins and viral RNA forming and contributing to the functional capsid structure. This will allow the identification of sites for potential drug targets and orientation of protein-protein and protein-RNA interfaces. Docking simulations will serve to identify binding sites, as well as potential drug candidates that fit into the sites. Existing screening methods can then assess whether these high-scoring drugs bind to their target proteins.
Before joining Torbett and Forli lab, Christina studied proton transporters with multiscale QM/MM (quantum mechanical/molecular mechanical) molecular dynamics simulations with Dr. Hai Lin at the University of Colorado Denver. Christina earned her Bachelor of Science in Public Health with a minor in Chemistry. She likes to spend her free time climbing, playing board games and participating in competitive jigsaw puzzling.

Torbett Lab, UCSD, TSRI Florida, and VMRF Working with a New Research Grant from NIH (October 1, 2018)
Dr. Bruce Torbett, Associate Professor of The Scripps Research Institute (TSRI), has received a subaward from the National Institutes of Health (NIH) through the University of California San Diego (UCSD).
The three-year grant will help fund the project entitled, “Opioid Impacts on T-cell Pathways and Epigenetics to Modulate HIV Integration, Latency and Reservoirs.” The project is designed in a two-stage process (R61/R63) to tease out the mechanisms of how opioids impact cellular receptor signaling for opioids, cellular co-receptors for HIV, epigenetic control (chromatin packing and methylation), and gene expression. It will also determine how these processes impact HIV replication, integration and latency.
Dr. David Smith of the UCSD School of Medicine is the Principal Investigator of the project. Other Co-Investigators on the grant include Dr. Laura Bohn of TSRI Florida and Dr. Celsa Spina of Veterans Medical Research Foundation (VMRF). Dr. Nadejda Beliakova-Bethell of VMRF, Dr. David Gorkin of UCSD School of Medicine, and Dr. Amalio Telenti of TSRI California are also named as key personnel.
The Torbett Laboratory’s expertise will be provided in evaluating morphine like-agonists and their effect on CD4T cells and macrophages HIV infection, latency and viral persistence in collaboration with Drs. Bohn and Spina. The Torbett group’s experience in HIV sequencing and informatics to evaluate HIV populations from the “final gift” patient cohort will also be utilized. Furthermore, Dr. Torbett will utilize novel RTs to generate full-length cDNAs from patient HIV samples to address whether there is genetic evolution of individual viruses within the viral population of HIV-infected patients before and during opioid use.
The Torbett Laboratory Welcomes New Postdoctoral Associate (September 4, 2018)
The Torbett Laboratory welcomes Shentian Zhuang, a Beijing native and a recent Ph.D. graduate from Peking University in China.

The studies better informed the field on BA’s regulatory roles in human physiology and diseases.
Shentian’s Scripps Resesarch fellowship studies, in collaboration with HIVE Center members, are focused on the identification and characterization of host proteins involved in HIV-1 Gag assembly and trafficking. She will develop chemical proteomics strategies to study metabolite-protein and protein-protein interactions in HIV infected and myeloid cell as well.
In her free time, Shentian enjoys watching movies, listening to music, and bein an innovative chef.
Geraldine Goebrecht Receives Training Grant from National Institutes of Health (September 3, 2018)
Geraldine Goebrecht recently received a four-year training grant (F30) from the National Institutes of Health (NIH) in support of a research project entitled, ” Lymph node-targeted delivery of HIV vaccine candidates.” The grant will provide funds for her tuition and fees, stipend, and an institutional allowance.
Geraldine’s work in the Torbett Laboratory now focuses on tracking the HIV capsid core as it moves towards and docks at the nuclear pore. Using SuFEx chemistry, developed by the Barry Sharpless group, she looks to establish a novel labeling strategy for HIV capsid allowing for the detailed visualization of core degradation.
To further characterize the completeness of capsid cores able to facilitate infection, she has designed cell lines capable of inducibly and reversibly halting nuclear entry. By controlling HIV’s entry into the nucleus, she will be able to assess those capsid structures poised to enable integration in too the host genome.
Geraldine has been in the Torbett Laboratory as a Graduate Student since May 2018. She is currently working on her doctoral degree in Biology through the Scripps Research Institute’s Skaggs Graduate Program. Upon completion of her doctorate, she will return to the UC San Diego School of Medicine to complete her medical training through the Medical Scientist Training Program.
